Although electric cars do not emit exhaust, it's widely recognized that the electricity to charge their batteries often still comes from fossil fuels. This has led to the scrutiny of electric cars to determine whether their overall "wells-to-wheels" carbon footprints exceed those of regular vehicles powered by internal-combustion engines.

Although electric cars do not emit exhaust, it's widely recognized that the electricity to charge their batteries often still comes from fossil fuels. This has led to the scrutiny of electric cars to determine whether their overall "wells-to-wheels" carbon footprints exceed those of regular vehicles powered by internal-combustion engines. For most... 
The industrial revolution that began around 1750 was powered in large part by coal, and the carbon-rich fuel had 200 good years after that. By the middle of the last century, however, serious studies had begun of its deleterious effects on human health—and that was before the climate-change impact of human emissions of carbon dioxide became... 
As rules to boost fuel economy and lower carbon emissions in vehicles around the world continue to stiffen, acronyms like EREV, CNG, and MPGe are becoming more and more common. Ever wonder what they all mean? This glossary is your chance to enter a veritable Twilight Zone of terminology--and find out, say, whether a PZEV is related to a PHEV... 
The future of energy production remains in considerable debate, but some new research provides a more optimistic view for a lower-carbon future. Sources for new and replacement energy production remain uncertain, especially the degree to which renewable sources can replace those based on fossil fuels. Even with the newer, optimistic predictions... 
The best analog to EPA administrator Scott Pruitt's latest action might be for the U.S. Geological Survey to undertake a "scientific critique" of theories that the world is round. After all, numerous authoritative sources over the years have raised doubts that the Earth is not flat. Surely their views deserve to be aired. Late last week, it... 
Yesterday, U.S. president Donald J. Trump signed an executive order to begin the process of rolling back pretty much every vestige of U.S. efforts to address climate change. In both his campaigning and since his inauguration, Trump has claimed that his government and its actions focus on creating or bringing back jobs for working-class Americans... 
One of the major sources of carbon emissions is electricity generation. It's an issue that is becoming increasingly important in the automotive sphere, due to the slow rise of plug-in electric cars. So what would it take to eliminate carbon emissions entirely from making electricity? DON'T MISS: Bipartisan governors' group urges Trump to back... 
Substantial growth in U.S. renewable-energy capacity will undoubtedly have a positive environmental impact. But the reduction in carbon emissions renewable-energy advocates aim to achieve does not exclude potential benefits to consumers. Because as renewable-energy generating capacity has expanded significantly over the last decade, household... 
While homeowners are more familiar with photovoltaic solar panels, large-scale wind power is an increasingly important part of the growth in renewable energy. For the first time, the total installed capacity of wind energy in Europe now exceeds the total output of electric powerplants fueled with coal. And that imbalance is likely to grow as more...
