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...

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...

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...

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...

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...

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...

Pity Energy Secretary Rick Perry, the man now running the cabinet department he couldn't remember that he wanted to eliminate altogether during a notorious 2011 presidential debate. He has pulled off an unusual feat, by uniting lobbyists for fossil-fuel interests with their counterparts advocating...

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...

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...

The best analog to EPA administrator Scott Pruitt's latest action might be for the U.S. Geological Survey to undertake a "scientific critique" of theories that the world is round. After all, numerous authoritative sources over the years have raised doubts that the Earth is not flat. Surely their...

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...

One of the major sources of carbon emissions is electricity generation. It's an issue that is becoming increasingly important in the automotive sphere, due to the slow rise of plug-in electric cars. So what would it take to eliminate carbon emissions entirely from making electricity? DON'T MISS...

As a presidential candidate, Donald Trump vowed to "bring back coal" as part of a larger program to encourage greater production of fossil fuels. But the coal industry believes it needs more than an ostensibly friendly administration in Washington to survive. With coal production down and electric...

Substantial growth in U.S. renewable-energy capacity will undoubtedly have a positive environmental impact. But the reduction in carbon emissions renewable-energy advocates aim to achieve does not exclude potential benefits to consumers. Because as renewable-energy generating capacity has expanded...

Mass adoption of electric cars and renewable energy could significantly decrease global consumption of fossil fuels. But does the established energy industry view these new developments as a threat? In a recent report, ExxonMobil said coal could continue to provide the majority of the world's...

Long a leader in the push to reduce vehicle emissions and switch to renewable energy, California marks another milestone this week. The last of three battery energy-storage sites will come online in Southern California, providing storage and buffering for unpredictable renewable energy. Together...

At first glance, renewable-energy sources like solar power and energy-storage battery packs seem like a logical match. Energy storage allows excess power collected by solar panels to be stored for later use, addressing the intermittent nature of solar power. It's a concept that has already won over...

Renewable energy sources may eventually render fossil fuels irrelevant in energy generation, but when will the switch between the two energy sources occur? It's a question that fosters much debate among policymakers, environmental advocates, and financial analysts. For its part, ExxonMobil believes...

From the perspective of both renewable-energy advocates and electric utilities, grid-scale energy storage offers many potential benefits. By storing energy in battery packs for later use, energy storage can make intermittent renewable sources like solar and wind into more reliable forms of power...
