Natural gas is growing as a part of the world's grid mix, because its carbon per kilowatt-hour is much lower. But methane leaks that emit large volumes of climate-change gas into the air may offset that advantage.

Natural gas is growing as a part of the world's grid mix, because its carbon per kilowatt-hour is much lower. But methane leaks that emit large volumes of climate-change gas into the air may offset that advantage. Now, a Google Street View car has allowed researchers to pinpoint and quantify the severity of natural-gas leaks in five different... 
Given the current political landscape in Washington, it's not unreasonable to worry about the future of U.S. efforts to combat climate change. The Trump Administration has embarked on an explicit mission to undo all Obama Administration efforts to reduce carbon emissions. Climate-science deniers in the current administration include Trump himself... 
While renewable energy gets significant press as an alternative to coal in electricity generation, it isn't the main factor in decreasing the use of that carbon-intensive fuel. Thanks to its generally lower cost, natural gas is quickly displacing other fuels in the nation's power plants. In addition to its cost benefit for electric utilities... 
The California Air Resources Board voted Friday to confirm its stricter emissions standards for 2025, setting up a potential clash with the Trump Administration. The CARB vote reaffirms a decision by the EPA in the waning days of the Obama Administration to lock in emissions standards for vehicles in model years 2022 through 2025. Under Trump, the... 
While political control in Washington has changed, the debate over a mandate to blend specific volumes of ethanol into the U.S. fuel supply has not. Since its passage in 2007 as part of the Energy Independence and Security Act, the ethanol-mandating Renewable Fuel Standard has attracted controversy. Its requirement of specific volumes of ethanol... 
California is very different from the rest of the United States. All by itself, it's the sixth largest economy in the world. One eighth of all Americans live there. It's home to Silicon Valley, as well as much of the global entertainment industry, and it produces a large proportion of the nation's fruit and vegetables. DON'T MISS: A Brief History... 
The auto industry tends to oppose, viscerally and viciously, all attempts to regulate any aspect of its products or business operations for any reason. With President Trump in the White House, the industry has succeeded in getting the comment period reopened for the EPA emission standards finalized ahead of schedule, covering vehicles in model... 
At the 2017 Geneva auto show, General Motors announced the sale of its entire European operations—comprising factories and the Opel and Vauxhall brands—to PSA Peugeot Citroën. German Opel and its British Vauxhall sibling have represented GM's main presence in Europe for decades, but the U.S. automaker was willing to let them go... 
It crops up in comments from electric-car advocates and clean-energy users fairly regularly. And it goes something like this: "Big Oil and Gas are on the verge of collapse, as clean energy and electric cars make them obsolete." Occasionally the sentiment is followed by an approving emoji. DON'T MISS: Electric cars pose little threat to oil demand... 
Fiat Chrysler Automobiles continues to be dogged by allegations that it cheated on various diesel-emissions tests. In the U.S., the company faces two lawsuits alleging that diesel vehicles use "defeat device" software to circumvent emissions tests in a similar manner to Volkswagen's cheating TDI vehicles. In January, the EPA said FCA had failed to... 
As it tries to put the ongoing diesel-emissions scandal behind it, VW Group is focusing its future on electric cars. The Volkswagen brand within the sprawling German company has developed an electric-car specific platform called MEB, and has shown multiple concepts based on it. Those include the ID hatchback, and the ID Buzz and Budd-e, both... 
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: Bipartisan governors' group urges Trump to back... 
Tomorrow is expected to be the day when President Donald Trump announces the EPA will reopen the comment period for the vehicle emissions standards it finalized in the waning days of the Obama Administration. The event will likely be accompanied by predictable language: Trump will be “highlighting the need to eliminate burdensome regulations... 
It seems fair to say that the new presidential administration may have increased the generalized level of worry among many Americans, not to mention the rest of the world. Among the things to worry about are the future of incentives, infrastructure, and legislation encouraging the adoption of zero-emission vehicles, primarily electric cars. These... 
Even with a new leader apparently at odds with its mission, the Environmental Protection Agency continues to function on some level. On Thursday, EPA administrator Scott Pruitt said carbon dioxide released by human activity is not a major cause of climate change, directly contradicting the scientific consensus. The day before that, however, the... ![Bill Nye in new 2017 Chevrolet Bolt EV, Jan 2017 [photo: Oskar Liners, Community Chevrolet, Burbank]](http://images.hgmsites.net/tmb/bill-nye-in-new-2017-chevrolet-bolt-ev-jan-2017-photo-oskar-liners-community-chevrolet-burbank_100590950_t.gif)
The U.S. Environmental Protection Agency is emerging as one of the government entities most targeted by the new Trump Administration for change. In this case, if reports of the administration's draft budget proposal are accurate, change means wholesale elimination of staff, funding, and programs. Yesterday, however, an even more remarkable fact... ![Smog obscures George Washington Bridge, 1973 [From EPA Documerica series]](http://images.hgmsites.net/tmb/smog-obscures-george-washington-bridge-1973-from-epa-documerica-series_100594067_t.gif)
Imagine putting a pacifist in charge of the U.S. Defense Department. Or appointing a committed racist to enforce civil rights in the country. The appointment of Scott Pruitt as the administrator of the U.S. Environmental Protection Agency could perhaps be viewed in a similar light. In his former position as Oklahoma attorney general, he sued the... 
China's latest effort to promote electric cars focuses on taxis in its capital city of Beijing. The country that is now the world's largest new-car market already offers generous purchase incentives for electric cars bought by individuals. Now the city also plans to replace its entire fleet of gasoline taxis with electric cars. DON'T MISS... 
California leads the nation in policies that promote reductions of carbon emissions from road vehicles. It is unique in having a federal waiver that allows it to set its own, stricter emissions standards, along with a zero-emission vehicle mandate that requires automakers reaching certain sales volumes to sell a certain number of cars without...
