When electric cars first arrived in 2011, it was a reasonable question: Aren't you just shifting emissions from the tailpipe to the smokestack? The answer is yes, but the carbon emissions per mile of an electric car—properly measured on a wells-to-wheels basis—are virtually always lower than those of a gasoline or diesel car. It's not... Electric cars emit less carbon than average U.S. new car, everywhere in the world

Everyone knows what a gallon of gasoline is, or what they paid the last time they put fuel in their car. But trying asking your friends, relatives, and neighbors how much they paid per kilowatt-hour in their last electric bill. Or even what a kilowatt-hour is. We guarantee you that 19 out of 20 of them won't have a clue. DON'T MISS: Chargeway: the... ![Containers holding spent nucleat fuel [Nuclear Regulatory Commission photo]](https://images.hgmsites.net/tmb/containers-holding-spent-nucleat-fuel-nuclear-regulatory-commission-photo_100501742_t.gif)
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 for renewable energy. Given the ascendance of... ![Tesla Kauai solar-energy generation and storage project [photo: Tesla]](https://images.hgmsites.net/tmb/tesla-kauai-solar-energy-generation-and-storage-project-photo-tesla_100625574_t.gif)
Tesla’s summer announcement of the world’s biggest battery-storage system in South Australia characteristically kept key details confidential. Fortunately, while mystery and mystique still shroud that project, more can be unearthed or inferred for Tesla's solar panel and battery energy-storage deployment in Kauai, Hawaii, which came... 
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 vehicles powered by internal-combustion engines. For most... ![The White House, Washington, D.C. [Creative Commons license by dcjohn]](http://images.hgmsites.net/tmb/white-house_100170583_t.gif)
The Trump administration has reneged on one aspect of a promise widely discussed throughout the 2016 presidential campaign: reviving the coal industry. President Donald Trump declared the United States coal industry would thrive under his watch, but the Trump administration and the Energy Department have just delivered a blow to the... 
For southern California residents, it's an excellent time to start considering the purchase of a BMW i3 or Nissan Leaf electric car. San Diego Gas & Electric has joined a host of other utility companies in the state in offering incentives towards the purchase of an i3 or a Leaf. In total, the incentives slash $10,000 from the purchase price of... 
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 impact of human emissions of carbon dioxide became... 
The future of energy production remains in considerable debate, but some new research provides a more optimistic view for a lower-carbon future. Sources for new and replacement energy production remain uncertain, especially the degree to which renewable sources can replace those based on fossil fuels. Even with the newer, optimistic predictions... 
The U.S. is coming up to its Independence Day holiday, in which we celebrate the Declaration of Independence from England and reflect on our history and traditions as a nation. This is an interesting time to do that, and there's a cynical argument to be made that backroom politics is as American as apple pie and bald eagles. Which brings us to the...
