Economic and Environmental Impacts of Plug-in Hybrids and Battery Electric Vehicles: A Comparative Analysis
<p>Greenhouse gas (GHG) emissions from anthropogenic sources are the leading contributors to global climate change. Over the past century, GHG emissions have increased tremendously due to causes such as deforestation and the burning of fossil fuels. In the US, about 28% of these GHG emissions come …

The Sustainability of Biofuels Produced from Microalgae
… to their worldwide depletion and greenhouse gas (GHG) emissions. Transportation biofuels produced from microalgae are sustainable if GHG emissions are lower than fossil fuels and the sources for materials used during production are sustainable. Four areas were evaluated to address these concerns. …
