The latest report from the EIA anticipates that total world energy investment will drop by 20% in 2020, due to the coronavirus pandemic.

The supply of materials—and specifically minerals—could be tightened due to restrictions aimed at the coronavirus pandemic.

The economic effects of the pandemic might drive a shift to renewable energy, suggests a recent report from the IEA.

A company aims to make the driveway a very productive part of your home—enough to power your whole house, potentially.

A report suggests that it makes no financial sense to continue to support coal as it's not more expensive than wind and solar. That's good news for electric cars.

At least one startup may be getting close to scaling up fuel production with carbon captured from the air. But burning the fuel would still pollute.

A transition to 100 percent renewable power would require huge investments in energy storage and may need new financial systems to trade energy.

The past couple of weeks have seen the convergence of two troubling trends. Perhaps most troubling, the Scripps Institute of Oceanography released data last week from the National Oceanic and Atmospheric Administration that concentrations of carbon in the atmosphere have reached record levels...

If electric cars are supposed to clean up the environment and reduce global warming—and they are—EV drivers would like to rely on 100 percent renewable energy to do charge. And charging networks are striving to provide it. Many, including Tesla with its Supercharger stations, are...

A new transmission line between Wyoming and the Hoover Dam could help solve some of the issues regarding renewable energy production and demand.

Tech giant Qualcomm sells its Halo wireless charging business to rival WiTricity. GM and Amazon could be in talks to invest in startup electric pickup-maker Rivian. A new computer model tests how a 100-percent renewable power grid would have held up to the recent polar vortex. And results of last...

There's nothing like a good polar vortex to put the power system to the test—unless maybe it's a summer heat wave. Energy consulting firm Wood Mackenzie used the opportunity of this event as a chance to measure demand on the power grid. In a detailed study of power demand during the severest...

Last week, two prominent Congressional Democrats released an outline of a "Green New Deal" that they hope will spur discussion and even commitment to eliminating fossil-fuel use. The Resolution picked up support from a wide range of other Democrats in Congress, while others expressed caution. The...

For electric-car drivers looking to emit less pollution as the drive, 2019 could be a banner year. The U.S. electric grid has been getting gradually greener as utilities replace coal fired powerplants with primarily wind and natural gas. That trend is due to reach a tipping point in 2019, according...

Sit down before you read this. Good. With all the dire warnings about climate-change coming from the most recent studies—from the Fourth National Climate Assessment released on Black Friday to an October report by the UN Intergovernmental Panel on Climate Change which showed that catastrophic...

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...

Over the years, we've noted the paucity of solid data on the intersection of home solar energy and driving plug-in electric cars. A California-only study from 2012 still gets quoted occasionally, and we continue to seek more recent and more comprehensive data. Out of a mix of curiosity and...

Drivers who buy an electric car that plugs into the power grid to recharge the battery often start to consider the source of their energy. A 2012 analysis from California, in the earliest days of modern electric cars, indicated as many as four in 10 electric-car drivers were already using or...

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...

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...
