Natural gas is growing as a part of the world's grid mix, because its carbon per kilowatt-hour is much lower. But methane leaks that emit large volumes of climate-change gas into the air may offset that advantage. Now, a Google Street View car has allowed researchers to pinpoint and quantify the severity of natural-gas leaks in five different... Google Street View car used to spot, quantify methane leaks
Natural gas is growing as a part of the world's grid mix, because its carbon per kilowatt-hour is much lower. But methane leaks that emit large volumes of climate-change gas into the air may offset that advantage. Now, a Google Street View car has allowed researchers to pinpoint and quantify the severity of natural-gas leaks in five different... 
Today, we have a drive report on Honda's hydrogen fuel-cell sedan, an unhappy Nissan Leaf owner, and Elon Musk playing stern daddy to an eager Model 3 buyer. All this and more on Green Car Reports. The Trump administration is working to wipe out all U.S. government climate-change efforts. What can you do to reduce carbon emissions yourself? The... 
There are now three different vehicles powered by hydrogen fuel cells on sale in California, and we've driven them all. The 2017 Honda Clarity Fuel Cell is the first one in which we were able to forget about the powertrain and simply drive. It's the best of the three, although that won't matter much to the majority of U.S. car buyers who live... 
Being a pioneer isn't easy. When you're pioneering new automotive technology, it can be challenging and sometimes costly. Just ask anyone who owned an early turbocharged sport sedan, for instance. That also applies, in some cases, to some of the first modern electric cars, and in particular the Nissan Leaf. DON'T MISS: Nissan Leaf leases can... 
Never let it be said that Tesla CEO Elon Musk isn't a man of strong opinions. His tweets are the stuff of legend, his dismissals of hydrogen fuel-cell cars as "fool cells" have been consistent for many years, and if you get his attention, he will definitely tell you what he thinks. Perhaps U.K. software developer Nick G hadn't really expected to... 
The 2017 Chevrolet Bolt EV is the first mass-priced electric car with more than 200 miles of range to go on sale in the U.S. That alone makes it a landmark vehicle, and has led to significant interest in the first electric car that provides comparable range to that of Tesla cars over the last nine years. Its maker, however, often refers to the... 
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... 
Most of the Volkswagen and Audi diesel cars sold in the U.S. from 2009 through 2015 are likely to be bought back from their owners, probably leaving fewer than 100,000 on U.S. roads. That's not the case in Europe, where the impacts of the Volkswagen diesel emission scandal are still playing out. Roughly 11 million cars with TDI diesel engines were... ![Section of 2018 Nissan Leaf spy shot [image via S.

The more camouflaged spy shots that emerge of a car being tested on public roads, the closer it likely is to being introduced. After seven years of the first-generation Nissan Leaf electric car, a redesign is due—some might say overdue. Now we have a second set of spy shots of the 2018 Leaf being tested, indicating a likely unveiling this...
