  • Tesla Powerpacks

    A new report on pollution, economic growth, and renewable energy in California sheds new light on the link between emissions regulations and economic growth ahead of the Global Climate Action Summit in San Francisco next month. The report released Thursday shows that even as the state implemented stricter emissions standards than other states and most countries, its economy continued to grow faster. The report, the 10th edition of the California Green Innovation Index, was produced by Next10, a non-profit research and education firm, and Beacon Economics, a California economic research and...

    Solar investment falls in midst of erupting trade war

    Electric cars and solar power fit together like a hand in a glove. Charging with solar power, electric cars can drive using almost no non-renewable energy. Now according to a report in Bloomberg New Energy Finance last week, solar investment has dropped by 19 percent worldwide in the second quarter...

    This one 11-year-old chart explains the problem with hydrogen fuel-cell vehicles

    Today, there are roughly 750,000 plug-in electric vehicles on U.S. roads and about 3,800 powered by hydrogen fuel cells. Proponents of each type of vehicle argue strenuously that their powertrain is a better way to produce vehicles with zero emissions from the tailpipe. Electric cars can be charged...

    Trump promised to save the coal industry; it hasn't happened

    You may recall that President Donald Trump made some ambitious and audacious campaign promises about his plans to revive America's dwindling coal industry. Two weeks ago, The Washington Post fact-checked the president's delivery on those promises after his first year in office—in multiples of...

    U.S. regulator rejects coal, nuclear bailout, says renewable energy may double by 2020

    For much of last year, U.S. Energy Secretary Rick Perry pursued a plan that, in essence, would prop up the financially challenged U.S. coal and nuclear industries. His proposal, submitted to the Federal Energy Regulatory Commission last fall, provided financial subsidies to electric-generation...

    It's not just the world automotive industry that's grappling with rapid changes brought about by the need to reduce the effects of climate change. The world's fossil-fuel extraction, refining, and delivery industries are also faced with the reality that two centuries of burning their core products...

  • Estimated U.S. energy consumption in 2016  [graphic: Lawrence Livermore National Laboratory]

    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. have lower wells-to-wheels carbon-dioxide emissions than the average new vehicle, their ability to slow those emissions that contribute to climate change is huge.

    Two-thirds of world's new energy capacity in 2016 was renewable: IEA

    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...

    Electric cars in UK cleaner than best diesels in summer, not yet in winter

    Although electric cars do not emit exhaust, it's widely recognized that the electricity to charge their batteries often still comes from fossil fuels. This has led to the scrutiny of electric cars to determine whether their overall "wells-to-wheels" carbon footprints exceed those of regular...

    'Fossil fuels are dead,' says CSX railroad chief: no more new trains for coal, ever

    The industrial revolution that began around 1750 was powered in large part by coal, and the carbon-rich fuel had 200 good years after that. By the middle of the last century, however, serious studies had begun of its deleterious effects on human health—and that was before the climate-change...
