Abstract:

Countries differ in terms of their socio-economic development, population growth, and energy consumption. Many countries still depend on conventional energy to supply enough energy source for their demand, while some have made considerable progress in making the transition to renewable/sustainable energy sources. Owing to the increasing demand and drawbacks of conventional energy sources, policies can play a major role in encouraging and increasing the uptake of renewable energy (RE) technologies. In this paper, a general overview on the RE activities in the three leading countries—China, Braz

Abstract:

In a world of technology and changing habits, but also driven by environmental awareness, renewable resources seem to be our last chance of saving the Earth. Some countries like China, the USA, Brazil or Germany have fully understood the need for alternative energy sources. Still, the emerging countries as well need to make an effort and invest in this field as soon as possible. That is why the present paper wishes to assess Romania's potential in what concerns renewable resources, emphasizing in the same time the level of some top investing countries.

Abstract:

The usage of renewable energies is approximately 11% of the matrix energy worldwide. In countries known for its renewable sources, such as Brazil, the percentage is close to 38%. The importance to study Stirling engines and propose a prototype is that they are a feasible alternative for generation of power and electricity when considering low quality sources such as solar and waste energy. This paper will compare two different approaches of the volume variation, sinusoidal and kinematic, using an isothermal model that represents the Stirling engines. The comparison is made for an a type engine

Abstract:

Shaping a secure and sustainable energy future may require a set of transformations in the global energy sector. Although several studies have recognized the importance of Electric Vehicles (EVs) for power systems, no large-scale studies have been performed to assess the impact of this technology in energy systems combining a diverse set of renewable energies for electricity production and biofuels in the transportation sector such as the case of Brazil. This research makes several noteworthy contributions to the current literature, including not only the evaluation of the main impacts of EVs’

Abstract:

Seasonal droughts occur in Northeast of Brazil by centuries, due to water shortage caused by the 2012-2018 severe drought, state governments have declared a state of emergency for most of the municipalities. As most of the municipalities depend on surface waters for the urban water supply system and the majority of water reservoirs in the Northeast being in a critical situation, the desalination of groundwater would be a feasible solution. This paper aims to identify municipalities in the state of emergency in the states of Ceará (CE), Rio Grande do Norte (RN), Paraíba (PB) and Pernambuco (PE)

Abstract:

The need for a diverse energy matrix has been promoting a favorable environment for integrating new renewable energy sources, such as Concentrated Solar Power plants (CSPs). Nonetheless, as a consequence of the incipient solar generation via CSPs in Brazil, there is a unsatisfactory number of researches that handle technical and economic assessments of CSP plants performance on this country. Given this scenario, this study proposes an assessment of the technoeconomic viability of the implementation of 100 MW CSP plants in Brazil, considering the Solar Tower (ST) systems, Parabolic Trough Colle

Abstract:

Brazil has abundant water resources and depends on them for hydroelectric power generation. In 2011, 81.9% of the electricity in the country was produced by hydropower. A significant change in the Brazilian hydrological cycle reduced this percentage to 64% in 2015. The scarcity of rain decreased the volumes in the reservoirs of the hydroelectric power plants located mainly in the Southeast, Center-West and Northeast regions. In this scenario, the National Operator System authorized the use in full load of thermoelectric plants powered by natural gas, biomass and coal. As a result, thermoelectr

In the face of the population’s growing awareness about environmental degradation, air pollutant emissions from electricity production become a very relevant issue. Therefore, the present work aims to evaluate the greenhouse gases (GHG), NOx and SO2 emissions in the Brazilian electricity production, using the expected capacity expansion from Ten-Year Energy Expansion Plan-2027, the current installed capacity of power generation and the electrical load factor.

The development of alternative energy sources in general and wind energy (including marine) in particular has become increasingly active in recent years. More and more countries around the world are seeking to incorporate the use of renewable energy into their daily lives to meet their international commitments and tasks. Among such tasks are global world policy to reduce greenhouse gas emissions, decarbonize the economy, production, and industry. The best and easiest way to achieve this goal has been the largescale implementation of legal regulation of non-traditional energy sources at both t

Electrical energy has become an essential resource for mankind and, as the population and technological dependency grow, also does the electricity demand. This necessity boosted numerous studies which focus on clean and renewable energy sources. Ocean wave energy is one of the most environmentally friendly sources of energy since it does not emit pollutants to the atmosphere and does not produce harmful waste. Another positive point about ocean waves is that they are inexhaustible, therefore a power plant could, potentially, provide energy indefinitely. Hence the object of this study is to est

The penetration of renewable energy into the electricity supply in Brazil is high, one of the highest in the World. Centralized hydroelectric generation is the main source of energy, followed by biomass and wind. Surprisingly, mini and micro-generation are negligible, with less than 2,000 connections to the national grid. In 2015, a new regulatory framework was put in place to change this situation. In the agricultural sector, the framework was complemented by the offer of low interest rate loans to in-farm renewable generation. Brazil proposed to more than double its area of planted forests a
