As India continues to urbanise with its manufacturing sector growing, its energy demands have increased rapidly. In this period, the need for energy monitoring and conservation must be evident. So the consumers can monitor their load consumption by a digital wattmeter. But the digital wattmeter measures and shows the total power consumed by consumer appliances. The consumer has no idea about which appliance consumes more power. Also, the consumer will not be able to know whether any appliance is getting damaged. To resolve these issues, we have come up with this project which is an IOT-based energy monitoring and controlling system, used to measure the power consumed by each appliance (Load). The power consumed by each appliance can be monitored individually by the consumer and it also informs us if there is an issue through a web application. Also the web application stores the historical data of the power consumed by each load. An Internet of Things (IoT) technique was employed to make the system smart. A microcontroller with built-in Wi-Fi - ESP32 - was used to monitor and control each load using a web application.

Abstract. The idea of designing a controller for electrical energy management is due to the need for energy saving and intelligent management of the consumed energy. The article presents the designed and studied device designed to limit the consumption of electrical energy within one day and the magnitude of the load current in single-phase circuits. Thus, the consumer (household consumer) of electrical energy can use the energy at time and in amount at will, but within pre-set limits. The paper discusses the principle of operation of the device for power consumption management, its main characteristics, and applications.

Abstract: It is realized that one of the defective subsystems adding to the tremendous budgetary loss in Power Supply Company is the conventional metering and charging framework. Mistakes get presented at each phase of charging the energy rates, similar to blunders with conventional meters, reading errors by human while noticing the consumed energy; and blunder during the preparation of paid and the due bills. The solution for this downside is a prepaid charging or billing framework of consumed energy. Most of the developing countries are shifting their conventional energy management practices to the modern one by replacing the old and conventional energy meters with the smart meters outfitted with the prepaid facility to quantify the power consumption so as to decrease the income deficits looked by utilities because of customer unwillingness to make consumed energy payments on time. Our proposed design embedded with Arduino and GSM technology is advancement over conventional energy meter, which enables consumer to effectively manage their electricity usage. The system performance is good with the acquired results. An earlier charging will undoubtedly get rid of the issues of unpaid bills and human mistakes in meter readings, along these lines guaranteeing justified income for the utility.

Full textAbstract:
Consumers are often poorly informed about the energy consumed by different technologies and products. Traditionally, consumers have been provided with limited and flawed energy metrics, such as miles per gallon, to quantify energy use. We propose four principles for designing better energy metrics. Better measurements would describe the amount of energy consumed by a device or activity, not its energy efficiency; relate that information to important objectives, such as reducing costs or environmental impacts; use relative comparisons to put energy consumption in context; and provide information on expanded scales. We review insights from psychology underlying the recommendations and the empirical evidence supporting their effectiveness. These interventions should be attractive to a broad political spectrum because they are low cost and designed to improve consumer decisionmaking.

Currently, such topics as improvement of energy efficiency of buildings and energy systems, development of sustainable building concepts, and promotion of renewable energy sources are in the focus of attention. The energy efficiency targets of the European Union are based on information regarding energy consumed by buildings. The amount of energy consumed by buildings depends on the main influencing factors (namely, climate parameters, building envelope, energy systems, building operation and maintenance, activities and behaviour of occupants), which have to be considered in order to identify energy efficiency potentials and opportunities. The article aims to investigate the total amount of energy consumed by a low energy house, built in Lithuania, using a combination of energy consumption data received from a simulation and measured energy consumption data. The energy performance analysis in the low energy house revealed some factors that have the main influence on the total figures of energy consumed by the house. The identified significant factors were used to find the optimal solutions for the design of low energy buildings.

Background: Energy beverages have become popular among youth, especially among university students, and the energy beverage market is a rapidly growing industry; it has many effects on health, so this study aims to assess patterns and factors affecting high-energy beverage consumption among university students. Methods: A cross-sectional design was used. An online self-administered questionnaire was used as a data collection tool. Results: The data reveal that 55.2% of the studied sample consumed energy beverages and half (98.8% and 80.3%) respectively, female and male students consumed high-energy beverages for 1 – 2 weeks with a significant statistical difference (< 0.001 and 0.000058) between male and female students regarding the frequency of consumption and a maximum number of cans consumed per day, (60.2% and 47.1% ) female and male students respectively consume high-energy beverages for the reason of study and exams which was the main factor for consumption. Conclusion: More than half of the studied university students consume energy beverages regularly, and about two-thirds are male. For most, the main factor for consumption was study and exams. Unawareness regarding the ingredients of high-energy beverages and the belief that high-energy beverages have a good effect on health were significantly associated with consumption.

Full textAbstract:
Snack foods can be substantial contributors to daily energy intake, with different types of snacks exerting potentially different effects on satiety per calorie consumed. The present research compared the effect of consuming almonds as a mid-morning snack compared to an energy and weight-matched comparator snack (savoury crackers) or the equivalent weight of water (zero energy control). In a crossover design, 42 female participants (age: 26.0 ± 7.9, BMI: 22.0 ± 2.0) consumed a fixed breakfast then a mid-morning snack. Appetite, 24-h energy intake, food hedonics, and consumer perceptions of the snack foods were assessed under laboratory conditions. AUC analyses revealed a lower overall hunger drive after consuming almonds compared to crackers or water. There was no difference in 24-h energy intake in the almond compared to the cracker or the zero-energy control condition, however participants consumed more energy in the cracker condition compared to the zero-energy control condition. In addition, almonds suppressed hedonic preference (implicit wanting) for consuming high-fat foods and demonstrated a higher satiety quotient (SQ) than crackers. Almonds were perceived to have a more favourable consumer profile aligned with successful weight management. In conclusion, these findings demonstrate that in the context of a 24-h period of objectively measured energy intake, raw almonds are effective for controlling appetite compared to an energy matched alternative snack. This trial was registered at clinicaltrials.gov [NCT02480582].

The team of Building environment in VŠB-Technical university of Ostrava works intensively on options in long-term accumulation of heat in underground storages. The new concept follows the Directive of the European Parliament and of the Council 2010/31/EU on the energy performance of buildings [1]. The Directive requires that energy should be extensively covered of renewable sources produced at or in the vicinity of building, where it will be consumed. The aim of the research is create thermal energy storage with model structure for complex of family house. For the storage will be used recycled materials especially recycled concrete. This system will be heat source in winter period and heat consumer in summer period.

Full textAbstract:
There have been vast changes in how net primary production (NPP) has been consumed by humans and animals through the Holocene. Here we ask: how much NPP energy may have become available following the megafauna extinctions? When did humans, through agriculture and livestock, consume more NPP than wild mammals? When did humans and wild mammals use more energy than was available in total NPP in each country? The megafauna extinctions potentially liberated ~2.2–5.3% of global NPP that early humans eventually consumed. By 1850, humans began to consume more than wild mammals (globally averaged). Currently, >82% of people live in ‘ecologically bankrupt’ countries where all plant production could not satisfy our energy demands. To summarize, we began the Holocene with an NPP energy surplus, became the dominant consumers of NPP over the natural world by the start of the Industrial Revolution, but now consume more total energy (including fossil fuels) than is available in NPP in most countries.

Full textAbstract:
The issue of deterioration in the quality of electrical energy as a result of its excess consumption is considered. Such consumption is due to insufficient supply of thermal energy. The concept of general energy consumption by business entities is proposed. Within the framework of the concept, all types of energy consumed by the consumer are taken into account and a correlation dependence of the replacement of one type of energy with another is derived. Thus, a mathematical model of the interconnected energy pool consumed by the consumer is created. Within the framework of such a model, electrical energy, as the most versatile, can act as a substitute or supplement for other types of energy in the consumption pool. It is proposed to measure the types of energy by its market value, adjusted to the needs and demand of the consumer. Moreover, the dependence of the present value should be adjusted in accordance with the energy level of the surrounding space (seasonal temperatures), the need for activity, and so on. The adjustment is proposed to be carried out by the corresponding statistical coefficients. The energy connectivity model is proposed to be built in volume as a combination of the ends of vectors proportional to the present value of the corresponding type of energy. The slope of the vector must correspond to the degree of substitution of one type of energy by another. Thus, the dependence of the mutual influence of various types of energy consumed by the consumer is obtained. The largest amount of energy in our climate is thermal energy. Therefore, the lack of thermal energy or its low quality must be compensated by other types of consumer energy consumption. Since electrical energy is the most versatile, it is used primarily to equalize the body's energy consumption. Such consumption leads to a deterioration in the quality of electrical energy. The concept of the mutual influence of energies is being developed, in which the concept of "energy consumption body" is introduced to enable visual representation and calculation of the influence of the interconnectedness of energies and the creation of a methodology that allows improving the quality of electrical energy by predicting overconsumption for the introduction of timely measures.

This study aimed to determine consumers’ liquid choices, their consumption frequencies and habits. The study was conducted on 332 individuals aged between 16 and 30 (mean age: 20.7 ± 3.1 years). The most important factors that affect consumers’ liquid choices are tastiness (74.7%), easy accessibility (71.4%) and being a continuously consumed beverage (69.3%), respectively. Of the participants, 78.0% consumed liquids at meals, 66.3% of them started the day with a drink, 65.4% controlled alcohol content in energy drinks, 62.3% consumed water while eating, 50.0% consumed water in the recommended amount and 46.7% paid attention to the warning statement when purchasing energy drinks. The liquids that participants consumed over the percentage consumption score were as follows: water (119.3%), tea (114%), ayran (83.7%), coffee (77.7%), fruit juice (66.9%), soda (65.8%) and milk (64.2%). It is thought that especially young consumers need to be informed about the healthy liquid choices and consumption habits.

European Union countries consumed in 2020 more energy than they produced themselves. Onlyits part was obtained from renewable sources (14.4%). Because of this, the Community focuses itsactivities largely on energy, where it is produced and the level of its consumption. To this purpose,through tools such as EU directives, it obliges Member States to reduce the energy they consume,as well as to increase the share of renewable sources in energy production. The paper analyses theenergy and climate targets for the European Union, particularly those for renewables and energyefficiency, for the oncoming years. In addition, the consumption and production of energy fromrenewable sources of each country was summarized. Only Sweden and Latvia have been shownto consume more than 50% of their energy from renewable sources. On the other hand, about58% of the EU’s consumed renewable energy in 2020 comes from biofuels and renewable waste.The countries’ dependence on energy imports is also apparent, but that from renewable sourcesusually does not account for a large share. It has also been shown that sixteen of the twenty-sevencountries import more than 50% of their energy needs.

Abstract Objectives Adolescents from low-income homes are shown to consume energy-dense snacks. However, less is known about the nutrient composition of snacks and the types of foods/beverages consumed as snacks. The overall aim of this study is to examine income disparities in, 1) nutrients consumed from snacks and 2) food/beverages consumed as snacks, among a nationally representative sample of U.S. adolescents. Methods Adolescents (12–19 years) who participated in the National Health and Nutrition Examination Survey 2005–2018, had reliable Day 1 24-h diet recall data, and reported at least 1 snacking occasion were included in the analyses (n = 7132). Nutrient density (g or mg/100 kcal) of snacks was reported for the following: protein, total fat, saturated fat, carbohydrates, total sugar, added sugar, fiber, sodium. We also reported the proportion of adolescents that consume various foods/beverages as snacks, using What We Eat in America (WWEIA) categories. We examined disparities in the aforementioned snacking characteristics by household poverty-to-income ratio (PIR): low-income (PIR ≤ 1.3), middle-income (PIR &gt; 1.3–3.5), and high-income (PIR &gt; 3.5). Data were analyzed using multiple linear and logistic regression models, adjusting for age, sex, and race/ethnicity. Significance was set at P &lt; 0.05. Results On average, adolescents consumed 185.35 kcal (9.30% of total energy intake) per snacking occasion. For every 100 kcals, adolescent consumed 2.02g protein, 2.87g total fat, 0.99g saturated fat, 17.16g carbohydrates, 10.62g total sugar, 1.69g added sugar, 0.88g fiber, and 120.11mg sodium. Adolescents from low-income homes consumed more energy (9.63%) and added sugar (1.76g) per 100 kcals than those from high-income homes (8.52%, 1.49g, respectively; P&lt; 0.05). The top 3 WWEIA categories of snacks were Snacks & Sweets (e.g., potato chips, cakes and pies; 73.3%), Beverages (51.9%), and Milk & Dairy (25.0%). Compared to adolescents from low-income homes, those from high-income homes were more likely to consume Snacks & Sweets (OR: 1.34, 95% CI: 1.05–1.71), but less likely to consume Beverages (OR: 0.69, 95% CI: 0.57–0.84). Conclusions Among U.S. adolescents, there exist income disparities in both the nutrient density of snacks and the types of foods/beverages consumed as snacks. Funding Sources N/A.

Abstract: It is an IOT based paper electricity is one of the fundamental necessities of human beings which is commonly Used for Domestic, Agriculture, Industrial purpose. Power theft and Meter billings are biggest problems in recent days which causes a lot of loss to electricity board. If we can prevent these thefts we can save a lot of power. This is done by Smart Energy Meter by using IOT, present an efficient and cost-effective way to transfer the information of energy consumed by consumer wirelessly as well as it provides facilities to detect illegal usage of electricity. Smart Energy meter by using IOT basically consists of three major components namely controller, Wi- Fi, theft detection device. Whenever there is any fault or theft, the theft detector sensor detects the error. The controller plays a crucial role in keeping all the components in the working state. In this system the energy meter is connected to internet. The proposed system is capable of continuously monitoring and being notified about the number of units consumed to energy provider and consumer. The energy consumption is calculated automatically, and the bill is updated on the internet by using a network of internet of things. This automation can eliminate the manual work in electricity maintenance. In this paper mainly focuses on automatic billing, theft detection, power optimization and providing the relevant energy consumption information to user.

Modern multi-core processors, operating systems and applied software are being designed towards energy efficiency, which significantly reduces energy consumption. Energy efficiency of software depends on algorithms it implements, and, on the way, it exploits hardware resources. In the paper, we consider sequential and parallel implementations of four algorithms of shortest paths search in dense weighted graphs, measure and analyze their runtime, energy consumption, performance states and operating frequency of the Intel Core i7-10700 8-core processor. Our goal is to find out how each of the algorithms influences the processor energy consumption, how the processor and operating system analyze the workload and take actions to increase or reduce operating frequency and to disable cores, and which algorithms are preferable for exploiting in sequential and parallel modes. The graph extension-based algorithm (GEA) appeared to be the most energy efficient among algorithms implemented sequentially. The classical Floyd-Warshall algorithm (FW) consumed up to twice as much energy, and the blocked homogeneous (BFW) and heterogeneous (HBFW) algorithms consumed up to 52.2 % and 21.2 % more energy than GEA. Parallel implementations of BFW and HBFW are faster by up to 4.41 times and more energy efficient by up to 3.23 times than the parallel implementation of FW and consume less energy by up to 2.22 times than their sequential counterparts. The sequential GEA algorithm consumes less energy than the parallel FW, although it loses FW in runtime. The multi-core processor runs FW with an average frequency of 4235 MHz and runs BFW and HBFW with lower frequency of 4059 MHz and 4035 MHz respectively.

The prevalence of energy drink consumption has increased in Hungary over the past 10–15 years. This study assesses the frequency, motivations, and adverse effects of energy drink consumption, and examines how the process of becoming a regular consumer is connected with sense of coherence and depression symptoms. A total of 631 high school and college students were assessed using the Depression Scale (BDS-13) and Sense of Coherence Scale (SOC-13). Logistic regression models were fit to test the effect of and links between factors influencing addiction to energy drink use. A total of 31.1% (95% CI: 27.4–34.7) of those surveyed consumed energy drinks, 24.0% of those affected consumed the energy drink with alcohol, 71.4% (95% CI: 64.7–77.3) experienced adverse effects following energy drink consumption, and 10.2% (95% CI: 6.7–15.2) experienced at least four symptoms simultaneously. The most common motivations of consumption were fatigue, taste, and fun. Obtained by multivariate logistic regression models, after adjustment for sex and age, SOC and tendency to depression had a significant influence on the respondents’ odds of addiction. The tendency to depression increases the chances of addiction, while a strong sense of coherence diminishes the effects of depression. Young people in Hungary have been shown to consume energy drinks in quantities that are detrimental to their health. Complex preventive measures and programs are needed to address the problem. Families and educators should strive to instill a strong sense of coherence in children from an early age.

Background: Commonly consumed foods may be nutritionally inadequate. Schoolchildren may be at risk of undernutrition as a result of this. Objective: To assess the nutrient and energy values of commonly consumed foods and determine their contributions to the recommended nutrient intakes (RNIs) of schoolchildren (6-15 years). Methods: List of commonly consumed foods was obtained through focus group discussions with parents of schoolchildren. Ninety randomly selected schoolchildren were visited at home on 3 consecutive days (2 weekdays and 1 weekend day) during which their portion sizes of these foods were obtained. Aliquots of these foods were collected, wrapped in polyethylene bags, and kept frozen until analysis. The samples were analyzed using standard methods. Percentage contributions of the nutrients to RNI were calculated. Data were analyzed by descriptive statistics. Results: Results per 100 g showed that Pentaclethra macrophylla ( akpaka) sauce had the highest moisture (76.91%), ash (6.9%), iron (13.51%), and vitamin A (44.0 retinol equivalent [RE]). Steamed bambara groundnut pudding ( okpa) had the highest protein (15.08%). Maize + pigeon pea ( ayaraya oka) had the highest fat (15.76%). Tomato stew proved superior in carbohydrate (28.15%) and energy (194.6 kcal). Pterocarpus soyauxii ( oha) soup contained the highest fiber (4.13%). Yam + pigeon pea ( ayaraya ji) had the highest zinc (4.97 mg). Contributions to RNI were protein (5.0%-134.0%), carbohydrate (0.6%-9.9%), energy (4.9%-38.8%), iron (1.5%-168.8%), vitamin A (0.0%-18.7%), and zinc (1.2%-166.0%). Conclusion: Most foods did not meet one-third of the schoolchildren’s RNI for vitamin A, zinc, iron, protein, carbohydrate, and energy. Nutrition education on nutrient adequacy is recommended.

Full textAbstract:
Cotton denim jeans are widely known to be among the dirtiest textiles available in the market. Denim jeans consume a significant amount of water, chemicals, and energy during their entire existence, from cultivation to disposal. This literature review examines the environmental impacts of denim production across four important phases: cotton cultivation, raw material processing, finishing, and disposal using conventional and organic methods. The environmental impact is classified into four areas using the life cycle assessment software openLCA 2.0.2. The four impact categories are: global warming, water consumption, freshwater ecotoxicity, and ozone formation in terrestrial ecosystems. Cotton cultivation makes use of a disproportionate number of chemicals (around 25 percent of the world's insecticides). Denim fabric manufacturing consumes 34, 38, 23, and 5 percent of total energy throughout the spinning, chemical process, weaving phase, and other operations, respectively. Besides, consumer use phase is the most resource consumed phase. People frequently discard or burn clothes, contributing to vast amounts of waste and harming the environment by emitting greenhouse gases. Cotton cultivation and conventional raw material processing produce the highest greenhouse emissions and use the most energy. Organic approaches emit 12 percent fewer emissions than conventional approaches. The conventional approach has a bigger environmental impact.

<abstract> <p>Energy consumption in the tertial sector is largely attributed to cooling/heating energy consumption. Thus, forecasting the building's energy consumption has become a key factor in long-term decision-making, reducing the huge energy demand and future planning. This manuscript outlines to use of the variance analysis method (ANOVA) to study the building's passive parameters' effect, such as the orientation, insulation, and its thickness plus the glazing on energy savings through the forecasting of the heating/cooling energy consumption by applying the Seasonal Auto-Regressive Integrated Moving Average (SARIMA) and the Long Short-Term Memory (LSTM) models. The presented methodology compares the predicted consumed energy of a baseline building with another efficient building which includes all the passive parameters selected by the ANOVA approach. The results show that the improvement of passive parameters leads to a reduction of heating energy consumption by 1,739,640 kWh from 2021 to 2029, which is equivalent to a monthly energy consumption of 181.2 kWh for an administrative building with an area of 415 m<sup>2</sup>. While the cooling energy consumption is diminished by 893,246 kWh from 2021 to 2029, which leads to save a monthly value of 93.05 kWh. Consequently, the passive parameters optimization efficiently reduces the consumed energy and minimizes its costs. This positively impacts our environment due to the reduction of gas emissions, air and soil pollution.</p> </abstract>

Shiftworkers have a higher risk of CHD and type 2 diabetes. They consume a large proportion of their daily energy and carbohydrate intake in the late evening or night-time, a factor which could be linked to their increase in disease risk. We compared the metabolic effects of varying both dietary glycaemic index (GI) and the time at which most daily energy intake was consumed. We hypothesised that glucose control would be optimal with a low-GI diet, consumed predominantly early in the day. A total of six healthy lean volunteers consumed isoenergetic meals on four occasions, comprising either high- or low-GI foods, with 60 % energy consumed predominantly early (breakfast) or late (supper). Interstitial glucose was measured continuously for 20 h. Insulin, TAG and non-esterified fatty acids were measured for 2 h following every meal. Highest glucose values were observed when large 5021 kJ (1200 kcal) high-GI suppers were consumed. Glucose levels were also significantly higher in predominantly late high- v. low-GI meals (P < 0·01). Using an estimate of postprandial insulin sensitivity throughout the day, we demonstrate that this follows the same trend, with insulin sensitivity being significantly worse in high energy consumed in the evening meal pattern. Both meal timing and GI affected glucose tolerance and insulin secretion. Avoidance of large, high-GI meals in the evening may be particularly beneficial in improving postprandial glucose profiles and may play a role in reducing the risk of type 2 diabetes; however, longer-term studies are needed to confirm this.

The energy consumption issue has become one of the significant problems that are given great attention by The governments, especially in the case of energy generation being less than required. It also has importance because of the rapid growth in the population and development and the dependence of millions of people on electric energy in their daily lives. In order to ensure the continuity of energy, it is necessary to regulate electricity consumption by providing the necessary real-time data to consumers. Currently, real-time data on energy consumption and information on the appropriate consumption time are not fully available for consumers. In addition, data is read manually at the end of each month to provide monthly invoices, a workforce is needed to complete this work, and errors occur due to human intervention. The proposed real-time invoice-based smart meter system is a measuring device to automatically read the data and provide the consumer with information on the energy consumed per hour, day, and month. The device helps the consumer choose the most suitable time for energy consumption and predicts the time when the amount of energy consumed exceeds the desired power.

Abstract The first cars with air conditioning appeared in the early 1940s. Then, 1500 Packard cars received an air conditioning system developed by Nash. In the 60s about 20% of the total production of cars had air conditioning system. Nowadays car manufacturers consider air conditioning as a standard option and try various solutions to increase thermal comfort and road safety. The air conditioning system in the current configurations is a big energy consumer system. All changes made to reduce the energy consumed will take into account temperature, humidity level, vibration and noise so that human safety and comfort are not affected. The purpose of this paper is to review the ways to reduce the energy consumed by the air conditioning system of cars and their importance.

<strong>Abstract</strong> This paper has presented energy efficient analysis of a heterogeneous Wireless Sensor Network (WSN). Wireless Sensor Network (WSN) can be applied for a variety of purposes such as security services in military and police operations, civilian and commercial services. The topology and routing algorithm for WSN was validated through simulation experiments conducted in MATLAB. Simulation results indicated that the overall energy consumed by the WSN topology was less than the initial energy of each node set as 2.0 J. With respect to the variation of energy consumed per traffic volume, it was observed that as the number of messages transmitted across the WSN increases, the average energy consumed per node and energy consumed by the network increases but with decreasing transmission capacity. In the case of the average energy consumed per node, the value increases from 0.0007418 J to 0.004425 J while the transmission capacity drops from 501-77 (84.6% reduction), and increases from 0.08632 J to 0.4011 J (maximum energy consumed) in terms of energy consumed by nodes with transmission capacity decreasing from 503 to 71 (85.9% drop) for 5000 messages to 30000 messages respectively.

This study aims to analyze the actual heating energy consumption according to the location and size of apartment houses. The study shows the variation in heating energy consumption in accordance with the living pattern of residents in such apartments. By calculating the average annual heating energy consumption and distribution of the measured heating energy of two years, it was found that the outdoor temperature was inversely proportional to the average heating energy consumption. Moreover, the lowest/highest floors and corner houses were the most vulnerable since they had a lot of area exposed to the outside air and, thus, consume a huge amount of heating energy. According to this study, the heating load had relevance to the factors such as wall loss, window loss, ventilation loss, and solar radiation gain that were analyzed in accordance with the growth in house size. Based on the survey outcome on the living pattern and number of residents, a simulation was conducted to analyze the variation in heating energy consumption. Households consumed the average heating energy for 15.8 h/day and occupied for 16.4 h/day. Households consumed more than the average heating energy for 22.2 h/day and occupied for 21.2 h/day, meaning 6.4 extra hours than those consuming the average heating energy. Households consumed less than the average heating energy for 5.2 h/day and occupied for 10.9 h/day, meaning 10.6 less hours/day than those consuming the average heating energy and 17 less hours/day than those consuming more than the average heating energy.

The influence of the structure of the electromechanical water supply system of a multi - storey building on its energy efficiency is investigated. A quantitative estimate of the reduction in the efficiency of the system compared to the supply of water to the top floor, depending on the number of floors. A complex mathematical model of the system with one and two risers (asynchronous motor - pump - branched hydraulic network) with determination of parameters of operating modes taking into account the mutual influence of system components is developed. The value of the system efficiency criterion as the ratio of the potential energy of water at the consumer to the consumed energy is substantiated and quantified. The electromechanical water supply system of a multi-storey building with two levels of risers consumes 30% less energy than the system with a single riser, due to the reduction of the amount of excess pressure in consumers of lower floors.

<em>Electricity boards and consumers are facing problems like unpredictability of power consumption bills, power theft, Unannounced power failure etc. The solution to all of these issues is to promptly monitor customer load, which aids in appropriate billing. Thus, a smart energy management system called Energauge is proposed to track maximum demand, prevent power theft, and optimize the energy usage of the consumer. The Static Digital Energy Meter is a system that measures the energy consumed by a load and regulates abnormal electricity usage due to multiple loads being used at once. The controller system monitors the load within a limit and uses an opto-coupler to collect the pulse from the energy meter. The consumed electricity is calculated based on the TNEB standard tariff-based slab rating, and a mobile app displays the consumed energy and cost by date. The electricity usage analyzer and controller system ensure that the maximum demand is monitored and controlled effectively. An electromagnetic power relay controls the maximum demand, which is fixed in the system. The power circuit and lighting circuits are connected to the electromagnetic relay, which activates the load only after the load has been reduced and the acknowledge push button has been pressed. The Static Digital Energy Meter is a reliable and efficient system that allows users to monitor and regulate their energy consumption. The proposed energy management system is implemented and tested in a real-time environment.</em>

In wireless sensor networks (WSNs), consumption of energy is the major challenging issue. If the data is transmitted directly from the node to the base station, it leads to more transmissions and energy consumed also increases if the communication distance is longer. In such cases, to reduce the longer communication distances and to reduce the number of transmissions, a clustering technique is employed. Another way to reduce the energy consumed is to reduce the transmission from node to CH or from CH to BS. Reducing the transmission distance is a NP-Hard problem. So, optimization techniques can be used effectively to solve such problems. In this article, is the implementation of a social group optimization (SGO) to reduce the transmission distance and to allow the nodes to consume less energy. The performance of SGO is compared with GA and PSO and the results show that SGO outperforms in terms of fitness and energy.

Full textAbstract:
Energy drinks are beverages marketed to quickly increase alertness and performance of the consumer that typically contain relatively high quantities of caffeine, simple carbohydrates, and a mixture of additional ingredients. The carbohydrate sources, usually glucose and sucrose, found in the beverages supply the substrates needed for physiological energy, while the high caffeine content supplies the perceived energy through enhancing feelings of alertness during fatigued states. Although mean youth caffeine consumption as a whole has decreased over the past 2 decades, adolescent energy drink consumption has significantly increased in the past 10 years. High energy drink consumption of youth is concerning due to the range of reported adverse reactions attributed to excessive caffeine consumption, ranging from mild sleep disturbances to death. Reactions are severe enough to require reporting to the National Poison Data System and may even require emergency medical treatment. Studies have also shown that adolescents who consume energy drinks are likely to also use tobacco, alcohol, and illicit drugs. There is substantial evidence to suggest that the risk energy drinks pose to health are incredibly hazardous and should not be consumed by children and adolescents.

Background: Consumption of energy drinks (EDs) has increased exponentially among younger generations, and this increase is projected to continue. Objectives: This study aimed to examine the prevalence, knowledge level, intake patterns, and consumer experience of consuming EDs among university students in Jordan. Methods: A cross-sectional study of 467 students from 29 universities was conducted by a webbased questionnaire. Descriptive analyses, chi-square tests, and logistic regression were performed, with a p-value of ≤0.05 indicating significance. Results: The prevalence of EDs was 40.1% among university students. Over half (62.7%) of students had poor knowledge of EDs. The most significant determinants identified were male (OR=2.18; 95%CI: 1.14-4.15), undergraduate (OR: 4.01; 95% CI: 1.70-9.72), in a nonmedical discipline (OR=2.92; 95% CI: 1.56-5.44), smoker (OR=9.91;95%Cl: 5.30-18.54) and having a poor knowledge level (OR=40.46;95%CI: 14.33-114.27). Students mainly consumed Red Bull, and the majority consumed 1-2 can(s) daily. Students were more likely to consume EDs during exams to mainly stay awake. The major side effects experienced by this sample were increased urination and headache. No changes in mental or physical performance, weight, appetite, and sleeping pattern were observed among the majority of respondents. Conclusion: Consumption of EDs was moderate among university students. Gender, study course, study year, smoking, and knowledge level were determinants of their intake.

The process of energy transformation is one of the crucial elements of the process of improvement of the quality of consumed energy. The aim of the research is to assess the European Union countries in terms of the quality of their consumed energy and the speed of adaptation of this aspect of the energy transformation process. We assess the quality of consumed energy by means of the synthetic measure obtained by means of the dynamic version of the COmplex PRoportional ASsessment (COPRAS) method. We compare the countries with the dynamics of the energy transformation process by means of the dynamic time warping method and the hierarchical clustering. Obtained results indicate the best countries with respect to the quality of consumed energy were Malta, Austria, and Germany, and the worst ones—Poland, Czechia, and Slovakia. The process of energy transformation was evolving in the right direction—the quality of consumed energy increased. This increase was the fastest in Malta, Luxembourg, and Poland. The direction for future research is extending the set of variables to also consider other aspects of the energy transformation.

Full textAbstract:
Abstract Buildings present a unique opportunity to not just effectively decrease global energy use but also drastically reduce nearly 40% of global carbon emissions to help mitigate the ongoing climate change. Although most of the building energy use is attributed to building operations as operational energy (OE), a portion of it is termed embodied energy (EE) that is consumed in building construction, transportation, and material production activities. EE of a building, therefore, includes energy consumed directly in onsite and offsite construction and transportation and indirectly through material consumption since each construction material consumes energy in its production and transportation. Like EE, buildings also consume significant amounts of fresh water directly and indirectly as embodied water (EW) in their construction, which is becoming a major concern globally. As fresh water is also depleted in producing and refining energy sources used as EE, a portion of this EW is attributed to energy-related water use (EREW). Most research so far has been focusing on the energy and carbon emission dimensions of buildings overlooking the equally important aspect of water use, which is also crucial for delivering a truly environmentally sustainable building. In this study, an input-output-based hybrid (IOH) model is created to compute and compare EE and EW of 10 higher education buildings and examine the correlation of the calculated EE and EW values. The results demonstrate that the total EE and electricity EE of the study buildings share a very strong positive correlation (r2 = 0.93-0.99) with the buildings’ total EW at the building level. This correlation, however, weakens at the material level. The share of EREW in the total EW ranges from 9-13%, which indicates that reducing just EE may not help decrease EW, and additional efforts may be needed to address EW and reduce fresh water use in building construction.

<abstract> <p>The construction of protected housing in Spain during the period analysed (1939–1989) reached its maximum between 1950–1980 with the construction of almost three million homes per year. The analysis of the homes built for railroad workers from this housing stock is distinct for four main reasons: it is a housing stock with a representative number of homes in relation to the total of social housing built in Spain, which is still mostly in use and covers all the typologies used in the country and which is dispersed throughout it. Thus, for the present analysis, there is a sample that is adequately representative of the whole stock of social housing constructed in Spain, this sample enables a comparative global analysis that can be extrapolated to the remaining stock. The objective of this study is to analyse the energy efficiency of homes through the thermal analysis of the envelope, as well as to acknowledge the specific constructive limitations of these homes and if possible, their rehabilitation that guarantees compliance with the required standards regarding sustainability and energy efficiency set by the Sustainable Development Goals (SDGs) established in the 2030 Agenda. This is a crucial goal to achieve, as the Spanish building stock currently consumes 30% of the total energy consumed, in addition to the socioeconomic profile and the potential for energy poverty, there is a portion of social housing with a precarious construction lacking the heating facilities, which is required due to the weather, with a significant potential for savings and the incorporation of renewable energies.</p> </abstract>

Malnutrition is a major public health concern in the Philippines. Milk and dairy products are important sources of energy, protein, and micronutrients for normal growth and development in children. This study aims to assess the contribution of different types of milk to nutrient intakes and nutrient adequacy among young and preschool children in the Philippines. Filipino children aged one to four years (n = 2992) were analysed while using dietary intake data from the 8th National Nutrition Survey 2013. Children were stratified by age (one to two years and three to four years) and by milk beverage consumption type: young children milk (YCM) and preschool children milk (PCM), other milks (mostly powdered milk with different degrees of fortification of micronutrients), and non-dairy consumers (no milks or dairy products). The mean nutrient intakes and the odds of meeting nutrient adequacy by consumer groups were compared, percentage of children with inadequate intakes were calculated. Half (51%) of Filipino children (all ages) did not consume any dairy on a given day, 15% consumed YCM or PCM, and 34% consumed other milks. Among children one to two years, those who consumed YCM had higher mean intakes of iron, magnesium, potassium, zinc, B vitamins, folate, and vitamins C, D, and E (all p < 0.001) when compared to other milk consumers. Non-dairy consumers had mean intakes of energy, total fat, fibre, calcium, phosphorus, iron, potassium, zinc, folate, and vitamins D and E that were far below the recommendations. Children who consumed YCM or PCM had the highest odds in meeting adequacy of iron, zinc, thiamin, vitamin B6, folate, and vitamins C, D, and E as compared to other milks or non-dairy consumers, after adjusting for covariates. This study supports the hypothesis that dairy consumers had higher intakes of micronutrients and higher nutrient adequacy than children who consumed no milk or dairy products. Secondly, YCM or PCM have demonstrated to be good dairy options to achieve nutrient adequacy in Filipino children.

Full textAbstract:
Ammonia can be produced from a wide range of raw materials such as coal, natural gas, coke and oil. Coal gasification is a process that converts biomass or fossil fuel-based carbonaceous materials into CO, H2 and CO2. A cryogenic air separation process was used to obtain oxygen from air because of high purity and high amount of oxygen, which will be used for coal gasification. For an ammonia synthesis process using pure oxygen gasification, the energy consumption of cryogenic air separation occupies a large proportion. The aim is to reduce energy consumed in the ammonia plant. The models of the process were developed with the aid of Aspen Plus. The energy consumption of the different processes was obtained through energy analysis, economic analysis and sensitivity analysis. From the three simulations, it can be seen that Simulation 3 produced oxygen with the highest purity of 0.979. From the energy analysis, the energy consumed on the total utilities in Simulation 1 was 5.626×1010 BTU/h with an energy savings of 1.55%, the energy consumed in Simulation 2 was 5.286×1010 BTU/h with an energy savings of 1.53% while the energy consumed on the total utilities in Simulation 3 was 1.425×109 BTU/h with an energy savings of 74.90%. Simulation 3 consumed the least energy. The economic analysis showed the total cost of each plant for a 10-year duration. Simulation 1 had a total operating cost of 42.083 billion USD/year, Simulation 2 had a total operating cost of 41.9615 billion USD/year and Simulation 3 had a total operating cost of 918.841 million USD/year. Therefore, Simulation 3 consumed the least cost of total operation. It can also be seen that the higher the energy consumption in a plant, the higher the total cost of the plant as Simulation 3 consumed the least energy, which justified that. Simulation 3 is the air separation plant that optimises the energy consumption, thereby reducing the energy consumed in the whole ammonia plant.

Use of computers, mobile phones and various hand held electronic devices are increasing rapidly in recent years. Several applications run simultaneously in these devices and some of the devices like mobile phones and laptops are battery powered. Desktop computers and servers running several applications starting from simple word processing to complex big data analytics, also consume a large amount of energy. Energy consumed mostly by hardware of the devices such as by CPU, memory units, networking interfaces and so on have become area of serious concern and the subject of Green Software Engineering have emerged to study ways for reducing energy consumption. Computer scientists and engineers are seriously looking at reducing energy consumption by various means including redesigning the algorithms. In the area of Green Software Engineering, accurate measurement of energy consumption is very important and various tools have been suggested for the purpose. In this paper, we have measured the energy consumption of various sorting algorithms using open source library jRAPL [6]. The energy consumed in joules was measured on six sorting algorithms and the values compared for different data sets. Comparison of the results is given in the paper.

Abstract Objectives Insulin takers’ diets have rarely been described although insulin dosing is highly dependent on dietary intake. The objective was to determine the most frequently consumed food or beverage items, food subcategories, and food categories, and items that contributing most to total energy intake among U.S. adult insulin takers compared with those with type 2 diabetes without taking insulin (T2D w/o insulin) and those without diabetes. Methods Fasting plasma glucose and hemoglobin A1c concentration from the laboratory tests and diabetic and insulin taking status from questionnaires in the National Health and Nutrition Examination Survey 2009–2016 classified 907 insulin takers, 2 758 T2D w/o insulin, and 34 360 participants without diabetes. U.S. Department of Agriculture Food codes of each item reported in the first reliable 24-hour dietary recall, were categorized by food subcategory and category based on What We Eat in America categories. Raw and weighted frequency and energy contributions of each food item, food subcategory, and food category were calculated and ranked. Results Diet soft drinks ranked 4th and 7th most consumed food subcategory in insulin takers and T2D w/o insulin, respectively. Soft drinks ranked 8th and 6th most consumed food subcategory in T2D w/o insulin and those without diabetes, and contributed 5th and 2nd most to energy, respectively (2.75% and 3.85% of total energy intake, respectively). Eggs and cold cuts were uniquely reported in insulin takers’ top 10 most consumed food subcategory list. Protein foods represented 4 rankings in insulin takers’ top 10 highest energy contributing food subcategory list including chicken, egg, meat dishes, and cold cuts (10.42% of total energy intake), 3 rankings in T2D w/o insulin list including chicken, egg, and meat dishes (7.22% of total energy intake), and only chicken for those without diabetes (2.70% of total energy intake). Conclusions Differences in dietary intake may exist among U.S. adults by diabetic status. Insulin takers are likely to consume more protein foods and less soft drinks compared to those with T2D w/o insulin and those without diabetes. Lists of the most frequently consumed foods and foods contributing most to energy may be helpful for nutrition education, prescribing diets, and technology-based dietary assessment for insulin takers.

The effect of embodied energy on energetic effectiveness of biodiesel production is studied. Embodied energy, i.e. energy consumed for production of a technical device, is gradually consumed during the life time of that device. The amount of embodied energy consumed during individual agricultural operation affects the energetic effectiveness of that operation, as well as that for the whole production process. The embodied energy in agriculture is associated with the use of machinery , transportation means, fertilizes, etc. The paper estimates the effect of embodied energy in the rapeseed biodiesel production basing on computer modelling.

Full textAbstract:
Abstract This article investigates the energy intensity and related impacts of the Eastern Route of China's South-North Water Transfer Project, based on the concept of the water–energy nexus. It finds that from November 2013 to May 2017 a total of 2.35 billion kWh of energy was consumed to transfer 15.5 billion m3 water driven by a large-scale system of pumping stations. This energy production required 7.4 million m3 of virtual water and emitted 1.93 MtCO2e of carbon. An average water–energy nexus ratio of 0.05% indicates that transferring 100 m3 of water consumes 0.05 m3 of virtual water due to the electricity consumption of the Eastern Route's pumping stations. It is estimated that to transfer 7.3 billion m3 water by 2030, this mega project will consume 1.35 billion kWh of energy, 4.6 million m3 of virtual water and emit 0.94 MtCO2e of carbon. These findings and scenario analysis demonstrate that strategies are needed for mitigating the energy intensity of the Eastern Route, such as improved pumping efficiency, reduced water loss during water delivery, decreased water quotas, and promotion of other, less carbon-intensive water sources in destination provinces.

Full textAbstract:
AbstractObjective:A consideration of eating patterns in the general population is necessary when deriving food-based dietary guidelines (FBDG) as promoting the intake of one food may indirectly result in the increased consumption of another, which may not always be desirable. A number of issues that influence meal patterns such as temporal distribution of food intake (using data from the Netherlands), converging and diverging foods (using data from Ireland) and meals eaten inside and outside of the home (using data from the UK) are examined and discussed in the context of developing FBDG.Setting:Food intake databases from three EU countries: The Netherlands, Ireland and the UK.Results:The hot meal (dinner) was found to be the main contributor to the intake of energy and macro-nutrients in the Dutch population. It was also the main contributor to the intake of all micro-nutrients with the exception of calcium where the bread meal contributed a similar proportion as the hot meal to the intake of this micronutrient. Furthermore, fruit intake showed a very different temporal distribution to vegetable intake. Exploring the convergence of certain foods in the Irish population also revealed differences between fruit and vegetables. A low correlation was shown for consumers of fruit and vegetables indicating that being a high fruit consumer did not suggest being also a high vegetable consumer. An examination of where meals were consumed among British adults showed that 71% of all meals were consumed inside the home while 29% were consumed outside. 27% of food energy and 45% of alcohol energy was consumed out of home by the total population. In addition, those eating less of their foods out of home obtained a lower proportion of their food energy from fat and protein and a higher proportion from carbohydrate. A different demographic profile was associated with eating out compared to eating in, comprising more males and younger individuals.Conclusions:Information on patterns of food intake and food habits, specifically temporal distribution, the convergence and divergence of foods and foods consumed inside and outside of the home, give a culturally specific picture of food consumption practices within a population. This should enable the development of more culturally acceptable and realistic FBDG.

AbstractObjectiveLittle is known about adolescents’ non-core food intake in the UK and the eating context in which they consume non-core foods. The present study aimed to describe types of non-core foods consumed by British adolescents in total and across different eating contexts.DesignA descriptive analysis, using cross-sectional data from food diaries. Non-core foods were classified based on cut-off points of fat and sugar from the Australian Guide to Healthy Eating. Eating context was defined as ‘where’ and ‘with whom’ adolescents consumed each food. Percentages of non-core energy were calculated for each food group in total and across eating contexts. A combined ranking was then created to account for each food’s contribution to non-core energy intake and its popularity of consumption (percentage of consumers).SettingThe UK National Diet and Nutrition Survey 2008–2011.SubjectsAdolescents across the UK aged 11–18 years (n 666).ResultsNon-core food comprised 39·5 % of total energy intake and was mostly ‘Regular soft drinks’, ‘Crisps & savoury snacks’, ‘Chips & potato products’, ‘Chocolate’ and ‘Biscuits’. Adolescents ate 57·0 % and 51·3 % of non-core food at ‘Eateries’ or with ‘Friends’, compared with 33·2 % and 32·1 % at ‘Home’ or with ‘Parents’. Persistent foods consumed across eating contexts were ‘Regular soft drinks’ and ‘Chips & potato products’.ConclusionsRegular soft drinks contribute the most energy and are the most popular non-core food consumed by adolescents regardless of context, and represent a good target for interventions to reduce non-core food consumption.

Energy meter monitoring with automatic tariff calculation is a project that can produce the output from energy meter to prepare a bill of electricity. Energy meter is a device that measure the amount of electric energy consumed. In Malaysia, the meter of Tenaga Nasional Berhad (TNB) travels for a long distance and take the reading manually to prepare the bill by visiting inside each of consumer house. This is high dependent on human forces. Sometimes the absence of consumer during billing process visiting make difficult to the meter reader to get the reader. Moreover many consumers are not satisfied with the estimate bills which are calculated based on average consumption. Soaring bill by estimate bills of electricity which consumer have to pay extra for the electricity billing. By using microcontroller and radio frequency transmitter for remote monitoring, the meter reader do not have to travel anymore. Global System for Mobile (GSM) uses to transmit and receive data from energy meter. The output which is calculated bill will be shown at Liquid Crystal Display (LCD) after apply the program coding in the microcontroller.

Full textAbstract:
Most Americans do not meet dairy food recommendations from the 2015 Dietary Guidelines for Americans (DGA). This study assesses differences in nutrient intake between Americans who meet recommendations for dairy intake and those who do not, using data from the National Health and Nutrition Examination Survey from 2013–2014 and 2015–2016 (n = 5670 children ages 2–18 years and n = 10,112 adults ages 19+). Among children and adults, those meeting dairy food recommendations were significantly more likely to have adequate intake (% above Estimated Average Requirement (EAR)) of calcium, magnesium, phosphorus, riboflavin, vitamin A, vitamin B12, and zinc and consume above the Adequate Intake (AI) for potassium and choline than Americans not meeting dairy recommendations, regardless of age, sex, or race/ethnicity. Americans meeting dairy recommendations were also more likely to exceed recommendations for sodium and saturated fat but consume less added sugars. Nearly 60% of Americans 2 years and older not meeting dairy recommendations consumed calcium and magnesium below the EAR. Only about 20% of Americans who did not meet dairy recommendations consumed above the AI for potassium. Dairy foods make important and unique contributions to dietary patterns, and it can be difficult to meet nutrient needs without consuming recommended amounts of dairy foods.

Full textAbstract:
Thirty-six normal-weight, habitual snackers (eighteen males, eighteen females) completed a medium-term intervention study designed to examine the tendency of four different types of snacks, varying in nutrient (low- (LF) or high-fat (HF)) and sensory properties (sweet (SW) or non-sweet (NSW)), to influence the control of appetite and to adjust daily energy intake. Subjects were exposed to each snack category for a 3-week period and were asked to consume a minimum number of snacks each day so that at least 25% of their daily energy intake would be derived from the test snacks. Energy and macronutrient intakes from the test snacks were calculated every day and also from other eating episodes (using 3 d food diary records) during the third week of snack exposure. Subjects consumed more energy/d from the SW snacks than from the NSW snacks, with most energy being consumed from the HF/SW snacks (3213 kJ) and least energy from the LF/NSW snacks (1628 kJ). This differential snack intake remained stable across the whole snack exposure period. Total daily energy intake did not differ significantly during exposure to any of the four snack types. Furthermore, the encouragement to eat freely from the test snacks did not lead to daily overconsumption of energy when compared with pre-study intakes. Hence, the level of snack consumption was largely compensated for by the energy consumed from the rest of the eating pattern. Although daily energy intake during exposure to the HF snacks was an average of 364 kJ higher (NS) than that during exposure to the LF snacks, the clearest and most significant effect of snack consumption was on daily macronutrient intake. Appreciable consumption of the HF snacks raised the percentage of total daily energy intake consumed as fat from 37 to 41% (P < 0.01). In contrast, the LF snacks reduced daily fat intake to 33.5% (LF/SW, P < 0.05; LF/NSW, NS) of total daily energy. The results, therefore, suggest that, in habitual snackers, generous consumption of LF snacks, when compared with HF snacks, is an effective strategy to reduce fat intake so that it approaches the recommendations of dietary guidelines without increasing total daily energy intake.

This study aimed to determine the description of energy drink consumption in Papuan athletes. Energy drinks are popular, and their consumption is increasing in today's fast-paced and active era, including among active workers and athletes. This study used a cross-sectional survey design involving 146 athletes using an accidental sampling technique. The energy drink consumption was known by a questionnaire consisting of 9 questions. The data to be collected includes sample characteristics (age, gender, sports, and last education), consumption, form, time, the purpose of consumption, perceived effect, amount, and side effects. The results showed that 52.74% of Papuan athletes had never consumed energy drinks, while 47.26% said they had consumed energy drinks. The energy drink consumption habits were 1-4 times in the form of sachets consumed during the day with no specific purpose. The perceived effect was the loss of tiredness with the amount taken one can/sachet/portion without experiencing side effects.

In developing countries like Nigeria, high energy inefficiency and poor technology have led to increased energy costs and wastage. This paper focuses on the second goal of the African Union Agenda 2063, which emphasizes the importance of science, technology, and innovation in creating well-educated citizens and a skills revolution. The objective is to investigate how evaluating and automating energy consumption can contribute to national development. The study utilizes a mixed-methods approach, gathering qualitative and quantitative data. The quantitative phase includes data collection from surveys via wellstructured questionnaires to quantify energy usage patterns and assess the potential for automation. The qualitative phase includes in-depth interviews with energy users on their perspectives on energy evaluation and automation. For data analysis, ETAP, SPSS, and Microsoft Excel version 2016 are utilized. Consequently, hardware and software applications are developed to automate energy consumption through the utilization of a microcontroller and a mobile app. The key findings reveal eight loads measured over a year that an automated meter consumed 806.65 Joules of energy, whereas the existing meter consumed 1447.23 Joules. This demonstrates that automated systems consume less energy compared to the existing meters. The study emphasizes the significance of efficient energy consumption for achieving sustainable development goals and explores the potential of automation in optimizing energy usage.

Abstract Objectives US adolescents with overweight (OW) and obesity (OB) consume larger and more frequent snacks (i.e., foods consumed between meals) than adolescents with normal weight (NW); but, the food group sources of these snacks by body weight status remains largely unknown. This research aimed to evaluate snack food group composition by weight status among US adolescents. Methods Cross-sectional analysis evaluated 10 USDA Food Patterns Equivalents Database (FPED) components from snacking occasions using two, 24-hr dietary recalls among U.S. adolescents (n = 6,591;12–19 y) participating in the 2005–2016 National Health and Nutrition Examination Survey. Analysis of covariance was used to evaluate food intakes by weight status, adjusted for energy misreporting and other covariates. Results Consumption of added sugars, solid fats, and refined grains from snacks alone represented 64%, 38%, 32%, respectively, of recommended daily limits. Adolescents with OB consumed greater total daily energy from snacks (NW = 441(11)kcal; OW = 540(17)kcal; OB = 645(23)kcal, P &lt; 0.05) and a greater percentage of total daily energy from snacks than adolescents with OW and NW (NW = 22%; OW = 24%; OB = 25%, P &lt; 0.05). Adolescents with OB also consumed significantly higher amounts of refined grains, dairy, protein, oil, solid fat, and added sugar from snacks and total daily intake than adolescents with OW and NW (P &lt; 0.05). Conclusions US adolescents consume one to two-thirds of recommended daily limits of added sugar, solid fats, and refined grains from snacks. Adolescents with OB consume higher levels of those and other food components from snacks than adolescents with OW and NW. Funding Sources National Institutes of Health; R21HD085137.
