Scientists generally debate their studies and projections in relatively civil language, but perhaps the currently adversarial tenor of U.S. politics has spilled over into science. A 2015 study on the potential for renewable energy use in the U.S. has now produced not only a stringent attack, but a harsh rebuttal to that attack in language rarely... Scientists debate: could renewable energy entirely replace fossil fuels in U.S. by 2050?

It's now widely acknowledged that the energy and electricity-generation landscape is changing rapidly. The U.S. has vastly increased its oil and gas production, driving down prices of fossil fuels globally. At the same time, ever-cheaper renewable energy—not only solar, but surprisingly fast-growing wind generation—is now... 
With more plug-in electric vehicles on the road today than ever, automakers are working to solve an impending issue: what to do with used lithium-ion batteries. Once the batteries are no longer suitable to power vehicles, automakers must recycle or repurpose them. Now, through a partnership with The Mobility House, the Renault Nissan Alliance is... ![Electric-car wells-to-wheels emission equivalencies in MPG, May 2017 [Union of Concerned Scientists]](http://images.hgmsites.net/tmb/electric-car-wells-to-wheels-emission-equivalencies-in-mpg-may-2017-union-of-concerned-scientists_100608699_t.gif)
Electric cars have no tailpipe emissions when running. But unless they're charged entirely on renewable energy—still statistically unlikely today—there are emissions associated with generating the electricity used to charge their batteries. For several years now, rigorous "wells-to-wheels" analyses of the carbon-dioxide emissions... 
The 2017 Nissan Leaf might well be the hottest electric car deal on the market right now, with a slew of potential discounts. Nissan is working with numerous partners to provide $10,000 off a 2017 Leaf lease, which adds to the $7,500 federal income-tax credit, giving a total of $17,500 in incentives. Among the partners offering the $10,000... 
Sometimes a picture is truly worth a thousand words. In the case of the rapidly rising rate of solar generation for electricity, numerous forecasts by internationally respected bodies have proven woefully conservative. The image in the tweet below, created by Auke Hoestra at the Technical University of Eindhoven, in The Netherlands, shows it... ![2015 Nissan Leaf with CHAdeMO fast-charging cable plugged in [photo John Briggs]](http://images.hgmsites.net/tmb/2015-nissan-leaf-with-chademo-fast-charging-cable-plugged-in-photo-john-briggs_100558582_t.gif)
California already offers generous incentives to get consumers into electric vehicles, but now the electric utility Southern California Edison has joined in. SCE has announced what it calls the Clean Fuel Rewards Program to offer a $450 purchase rebate for battery-electric and plug-in hybrid vehicle owners. The utility company isn't limiting the... 
It is widely accepted in the energy industry that U.S. coal production will fall as a percentage of the total electric grid mix. That has little to do with its high carbon footprint per kilowatt-hour generated; it is largely due to far greater supplies of much cheaper fracked natural gas. It is also widely accepted that renewable energy sources...
