As more governments sign on to ban internal combustion cars going forward, some are also pulling forward the dates they plan to implement those bans. Last week, Britain, which already had a ban on new gas and diesel vehicles without plug-in capability on the books starting in 2040, tightened its anti-global warming rules with a new measure that... New vehicles in Britain could go all plug-in by 2035
As more governments sign on to ban internal combustion cars going forward, some are also pulling forward the dates they plan to implement those bans. Last week, Britain, which already had a ban on new gas and diesel vehicles without plug-in capability on the books starting in 2040, tightened its anti-global warming rules with a new measure that... 
There's a lot of good data to be found in public reports from national labs and other government research papers, but it's not always easy to find or easy to parse. For years, federal Department of Energy collected and published that information—but it has eliminated that effort under the Trump Administration. So the Natural Resources... 
A majority of the photovoltaic solar panels used in the U.S. are imported from such countries as China, Malaysia, South Korea, Thailand, and Vietnam. Now, environmentalists and energy analysts worry that the new 30-percent tariff on solar-panel imports announced last Monday by President Donald Trump may stymie the rapidly growing clean-energy... 
Tesla CEO Elon Musk made a bet that he'd build the world's largest lithium-ion battery in Australia in 100 days. If his company failed, Musk would personally pay for the project, but the battery is now ready for its first test ahead of full operation—and on schedule. The massive 129-megawatt-hour battery will plug into South Australia's... ![Estimated U.S. energy consumption in 2016 [graphic: Lawrence Livermore National Laboratory]](https://images.hgmsites.net/tmb/estimated-u-s-energy-consumption-in-2016-graphic-lawrence-livermore-national-laboratory_100634001_t.gif)
One of the interesting side effects of plug-in electric cars turns out to be a greater awareness of energy sources and uses. A 2012 California study, for instance, showed roughly four out of 10 electric-car drivers either had or were considering solar panels to provide electricity to their home. And because electric cars everywhere in the U.S... 
Although claims of imminent volcanic eruption are likely exaggerated, any eruption of what's known as the Yellowstone Supervolcano would cause global chaos. Through intense monitoring programs, scientists have a clear idea of the Yellowstone volcano's behavior. Now NASA scientists are exploring a radical idea that could one day neutralize the... ![Tesla Kauai solar-energy generation and storage project [photo: The Verge]](https://images.hgmsites.net/tmb/tesla-kauai-solar-energy-generation-and-storage-project-photo-the-verge_100625575_t.gif)
For years, renewable energy has been cast as the most expensive option to reduce emissions and the world's reliance on fossil fuels. But 2016 may have marked a turn for the renewable energy sector, with solar energy in particular rising significantly in output. For the first time in history, renewable energy sources accounted for fully two-thirds... 
The Senate Committee on Appropriations recently exhibited a quality somewhat rare in U.S. politics these days: bipartisanship. The committee released a lengthy report on the 2018 fiscal year budget for the Department of Energy that walks away from the Trump Administration's efforts to defund clean energy. In fact, the committee voted on a... 
Olive drab isn't the only green thing in the U.S. Army. Currently undergoing testing at Fort Carson in Colorado, the Chevrolet Colorado ZH2 hydrogen fuel-cell vehicle illustrates the unlikely intersection between eco-friendly powertrains and the demanding needs of a vehicle that may be deployed to a war zone. The Colorado ZH2 is a collaboration... 
The White House declared this past week "Energy Week" and offered up a few key points on which the Trump administration plans to focus to unleash what it calls a new American dominance in energy. However, neither the initiatives nor the proposed policy changes hone in on where the world is heading: renewable energy, free of fossil fuels. Instead... 
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... 
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... 
No matter how you measure it, 2016 was a major year for solar energy. More solar-generating capacity was added last year than either natural gas or wind, according to the U.S. Department of Energy. A study by investment bank and research firm Lazard found that utility-scale solar has now become the single cheapest form of unsubsidized electricity... 
The combination of Tesla and SolarCity is already promoting its potential synergies, albeit in a location far away from the mainland United States. The island of Ta'u in American Samoa is located more than 4,000 miles from the U.S. West Coast, and typically relies on imported diesel fuel to generate electricity. With no local sources of fossil... 
Over the past few years, China has made impressive strides in renewable-energy investment. The promotion of renewable energy will only become more important as China works to meet its commitments under the recently-ratified Paris climate agreement. But the country's reliance on coal for electricity generation still poses a huge problem for these... 
The energy sources used to generate grid electricity can be a major source of greenhouse-gas emissions, and thus they affect the environmental impact of electric cars. The cleaner the electricity used to charge an electric car, the cleaner that car becomes in operation. And among potential energy sources, hydroelectric power from dams would seem...
