Abstract:

The Environmental Kuznets Curve is an inverted U-shaped relationship which demonstrates how environmental degradation increases as countries begin to develop and lowers as they become wealthier. The classical EKC measures the effects of GDP per capita (a country’s wealth) on pollu-tion. This paper is a study of the connection of a number of factors- GDP per capita, fossil fuels, al-ternative and nuclear energy, rural population and life expectancy at birth to the Environmental Kuznets Curve. Two econometric approaches are applied in order to test whether the variables have a more pronounced li

Abstract:

The European power sector is facing significant challenges related to investments in grid infrastructure and generation capacity. The continued deployment of intermittent renewables also puts pressure on current grid conditions. Smart grids is seen as a cost-efficient way to overcome these challenges through a more efficient use of current capacity. Demand response is a corner-stone in smart grid development, and is implemented to introduce flexibility on the demand side. Most demand response programs have used dynamic pricing to incentivize consumers to shift consumption from peak to off-pea

The U.S. electric power sector is in the early stages of transitioning from a reliance on carbon intensive generation sources to a system based on low-carbon sources.

The effects of bulk electricity storage on the PJM market I analyze the value of three storage technologies in the PJM day-ahead energy market, using a reduced-form unit commitment model with 2010 data. I find that large-scale storage would increase overall social welfare in PJM. However, the annualized ca

Abstract:

Two weeks before the Copenhagen summit on climate change, China officially made a pledge to cut its carbon intensity by 40 to 45 percent below 2005 level by 2020. The thesis has tried to look into the quality and quantity concern of this pledge made by the biggest CO2 emitter in the world. From the existing projections on China’s business as usual (BAU) scenarios to 2020, there are no unanimous conclusions showing whether there is additionality in China’s pledge to reduce 40-45% of its carbon intensity between 2005 and 2020.

I have tried to address the physics of laser-plasma interactions in a comprehensive way, emphasizing the correlation between various phenomena. The theoretical part is based on a monodimensional analytical description of the plasma created by direct laser irradiation of the target. Such description takes into account the absorptio

Abstract:

Temperate forests are an important carbon sink, yet there is debate regarding the net effect of forest management practices on carbon storage. Few studies have investigated the effects of different silvicultural systems, and the relative strength of in-situ forest carbon versus wood products pools remains in question. Our research (1) describes the impact of harvesting frequency and degree of post- harvest structural retention on carbon storage in northern hardwood-conifer forests, and (2) tests the significance of including harvested wood products in carbon accounting at the stand scale

Land ecosystems absorb about a quarter of all human emissions of carbon (C) by fossil fuel burning and land use change. This percentage varies greatly within years due to the land ecosystem response to climate variability and disturbance. Significant uncertainties remain in our knowledge of the magnitude and spatio-temporal changes in the land C sinks. The aims of my thesis are 1) to evaluate the capacity of different dynamic global vegetation models (DGVMs) to reproduce the fluxes and stocks of the land C cycle and 2) to analyse the drivers of change in the land C over the last two decades (1

Prior research suggests lawns sequester large amounts of carbon, but the effects of different management regimes on this is poorly known. Within the Eugene-Springfield, OR urban area lawn management ranges from intensive (high: weekly mowing, summer irrigation, herbicide and fertilizer application) to non-intensive techniques (low: spring and fall mowing, clippings left on lawn). I examined if these two regimes affect soil carbon content and vertical distribution after at least 20 years of consistent management.

Abstract:

There is a growing demand for climate reporting of digital solutions and Internet services. However, the impacts of data transmission have historically been the least studied part of the ICT sector and in the few studies that exist, the magnitude of Internet energy intensity varies by a scale as large as 20,000. This indicates that the assessment of network traffic is a complex task, and there is currently no consensus of how to correctly assess it. In an attempt to guide process development within the area, this report sought to identify and address potential challenges with assessing the en

To effectively inhibit the use of private vehicles, common strategy is to raise the cost of private vehicles, so fuel user fees and carbon tax play an important role in this regard. Therefore, a thorough study and analysis for the fuel user fees and carbon tax will be introduced in the resea

Abstract:

Excessive emission of carbon has emerged as the single most dangerous threat in recent times towards the earth’s environment and well being. A fair bit of damage has already been caused to the environmental ecology and a continuous deterioration is being seen in the climatic behaviour all over the world. A lot of scientific research has being going to study these emissions effectively which will help in reducing its concentration in the future without hampering the fast economic advancements going on.

How to keep the balance between tourism development and tourism carbon emissions is an important issue. Therefore, the research aims to explore the relationship between tourism GDP and tourism carbon emissions through decomposition analysis to catch the dynamic change in the period from 1999-2015 in Taiwan.

Modified Environmental Kuznets Curve, la letteratura non è unanime: non c’è accordo né sui coefficienti stimati né sui loro segni, poiché diversissimi sono i contributi.

The results showed that economic development had a positive influence upon the carbon emissions, but the rate of increase became slow at 22% of GDP per capita. Population and carbon emissions had a relationship that gradually rose, then unchanged, and finally declined. The possible reasons were that in the developed countries, people realized the importance of carbon pollution control

Abstract:

Brown macroalgae or brown seaweed is a promising source of ethanol that may avoid the challenges of arable land use, water use, lignin content, and the food vs. fuel debate associated with first generation and cellulosic ethanol sources; however, this promise is challenged by seaweed’s high water content, high ash content, and natural composition fluctuations. Notably, lifecycle studies of seaweed ethanol are lacking in the literature. To address this gap, a well-to-wheel model of ethanol production from farmed brown seaweed was constructed and applied to the case of Saccharina latissima farmi
