Months into Donald Trump's presidency, it is clear the administration has worked diligently to downplay the role of science in setting policy on energy. Some moves to diminish scientists' roles have been more evident than others, but a new report details what has gone on behind the scenes. In...

The question is a reasonable one: electric cars may be zero-emission, but what about the electricity to recharge them? While renewable energy is growing globally, burning fossil fuels is still the source of most electric power today. The good news is that in most areas of the U.S., the "wells to...

Transitions into new technologies always generate confusion and misinformation, and certainly that has been the case with modern electric cars. Buyers, automakers, and analysts debate their cost, suitability, real-world range, wells-to-wheels carbon footprint, and recyclability, among other issues...

A Union of Concerned Scientists survey shows which states and carmakers lead in promoting electric cars.

Personal automobiles have given hundreds of millions of people the great luxury of a convenient and comfortable mode of transportation. But there's no escaping that manufacturing these vehicles, driving them for 10 years or more, and then disposing of them creates pollution that has a wide range of...

The Union of Concerned Scientists revises its carmaker emissions rankings in light of the Volkswagen diesel scandal.

Electric cars have no tailpipe emissions, but their overall impact on the environment includes the electricity generated to recharge their batteries. The carbon emissions associated with that power vary greatly, depending on the local utility that provides it. Now an updated study from the Union of...

The hydrogen fuel-cell cars being promoted as the future of zero-emission transport--aggressively by Toyota, slightly less so by Honda and Hyundai--generate quite a lot of controversy. Now a new analysis by the Union of Concerned Scientists suggests that the wells-to-wheels carbon emissions of a...

Honda has long had the reputation of offering fuel-efficient, relatively green vehicles--but this year, it has lost the "Greenest Automaker" laurels that it's held since 1998 to an upstart: Hyundai-Kia. The latest award, detailed in a report that's now been issued six times by the Union of...

Every so often, electric-car skeptics will attack the idea of using grid electricity to power a car by bringing up coal. "Yeah," the argument goes, "but you're just burning coal instead of gasoline in your electric car--so how's that any better?" There is, of course, a fair amount of science that...
