If plug-in electric cars and trucks receive purchase incentives from national and state governments, what about electric bicycles? That's just what a recent report from the European Cyclists Federation suggests. It recommends directing purchase incentives and infrastructure subsidies towards electrically assisted bicycles, known as e-bikes... 
No vehicle on earth is entirely free of emissions; even electric cars charged on renewable energy have emissions associated with their manufacturing. Those emissions, however, are a tiny fraction of the carbon dioxide and other substances emitted by gasoline or diesel cars when scientifically assessed on a "wells to wheels" basis. This is well... 
The ability to travel long distances has long been a distinguishing feature of Tesla's luxury electric cars, whose Supercharger fast-charging network now offers access to essentially every part of the 48 continental states. But where hydrogen infrastructure exists, which can cover a long road trip faster: a hydrogen fuel-cell vehicle or a Tesla?... 
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... 
California is very different from the rest of the United States. All by itself, it's the sixth largest economy in the world. One eighth of all Americans live there. It's home to Silicon Valley, as well as much of the global entertainment industry, and it produces a large proportion of the nation's fruit and vegetables. DON'T MISS: A Brief History... 
About 600,000 plug-in electric cars have been sold in the U.S. in the past 10 years. The number for hydrogen fuel-cell vehicles is lower: as of the end of last month, it's below 1,600. Nonetheless, Honda, Hyundai, and Toyota today offer zero-emission vehicles powered by hydrogen in limited areas of California, and other makers are likely to launch... 
For 50 years now, California has been at the very forefront of reducing vehicle emissions. It was doing so before the U.S. Environmental Protection Agency was even formed, and its powerful Air Resources Board has been a vital force in getting plug-in electric vehicles onto the state's roads. Despite the national political currents, the state will... 
Well, never let it be said that this site's readers don't practice what they preach. We asked our Twitter followers when they thought they would buy their very last gallon of gasoline ever. Remarkably, one third of them (35 percent) said they had already done so. DON'T MISS: What will you be driving 10 years from now? Poll results That means they... ![Cumulative battery-electric and plug-in hybrid sales in California to hit 250,000 in Nov 2016 [PEVC]](http://images.hgmsites.net/tmb/cumulative-battery-electric-and-plug-in-hybrid-sales-in-california-to-hit-250000-in-nov-2016-pevc_100581772_t.gif)
It's long been obvious that California is the epicenter of emission reduction and electric-car adoption in the United States. And its outsize influence on U.S. environmental policy has global ramifications as well. Of the 1.25 million plug-in vehicles estimated to be on global roads by the end of this year, fully one-fifth are in the Golden State...
