This study analyzes the climate change and economic impacts of food waste in the United States. Using loss-adjusted national food availability data for 134 food commodities, it calculates the greenhouse gas emissions due to wasted food using life cycle assessment and the economic cost of the...

The increase of renewable sources in the power sector is an important step towards more sustainable electricity production. However, introducing high shares of variable renewables, such as wind and solar, cause dispatchable power plants to vary their output to fulfill the remaining electrical...

Waste-to-ethanol conversion is a promising technology to provide renewable transportation fuel while mitigating feedstock risks and land use conflicts. It also has the potential to reduce environmental impacts from waste management such as greenhouse gas (GHG) emissions that contribute to...

Accelerating demand to reduce the environmental impact of fossil fuels has been driving widespread attention to renewable fuels, such as biogas. In fact, in the last decade numerous policy guidelines and laws regarding energy, the environment and agriculture have been issued to encourage the use...

The need to reduce dependency on fossil resources and to decrease greenhouse gas (GHG) emissions is driving many countries towards the implementation of low-carbon electricity systems. In this study the environmental impact of a future (2030) possible low-carbon electricity system in Denmark was...

This work aims at optimizing life cycle performance of a hybrid combined cooling heating and power (CCHP) system incorporating with solar energy and natural gas. A basic natural gas CCHP system containing power generation unit, heat recovery system, hybrid cooling system and storage tank, is...

Western Canada is endowed with considerable reserves of deep un-mineable coal, which can be converted to syngas by means of a gasification process called underground coal gasification (UCG). The syngas can be transformed into hydrogen (H2) through commercially available technologies employed in...
