The California startup Prometheus Fuels is one of many efforts aiming to scale up a process that can sound remarkably simple: “We remove CO2 from the air and turn it into gasoline.” The process, which has in recent years seemed alternately like a Holy Grail or a red herring for the oil and gas industry, has already been achieved.

The California startup Prometheus Fuels is one of many efforts aiming to scale up a process that can sound remarkably simple: “We remove CO2 from the air and turn it into gasoline.” The process, which has in recent years seemed alternately like a Holy Grail or a red herring for the oil and gas industry, has already been achieved.

Within the next decade, companies and fleet operators face a serious logistics dilemma: If the future is autonomous and electric, as some major automakers now argue, the only way this works smoothly is if the charging is as well-automated as the driving itself. That’s what Electrify America plans to study together with the San Francisco... 
“Reduce, reuse, recycle” is one of the core concepts for greening your life—and with the right motivations along the way, reducing your carbon footprint. It’s part of what makes the idea of electric-car conversions so compelling. You take a tired, polluting old vehicle with a tailpipe, remove everything having to do with... 
The all-electric Ford F-150 teased for the first time last week is something to get excited about—especially as an electric version of the top-selling vehicle in America. The model isn’t likely to show up at dealerships for at least another couple years, though. And there are electric F-150 pickups already in use today. About a dozen... 
We’ve all seen it while following big rigs: Clouds of sooty smoke coming from a single truck, prompted by an uphill grade, a passing maneuver, or sometimes seemingly nothing at all. How can that be legal? It might not be legal, but it underscores a current loophole in U.S. emissions for larger (Class 4-8) trucks: There’s no mechanism... 
At the start of a call Wednesday to provide guidance on Tesla’s record sales but $408 million loss in the second quarter, Tesla CEO Elon Musk dropped a bombshell: that its chief technical officer, JB Straubel, will be stepping down from his executive post. Drew Baglino will take over most of the responsibilities held by Straubel, who will be... 
Tesla is facing pressure about pricing from all directions. Despite strong delivery numbers, the California automaker announced it posted bigger losses Wednesday for the second quarter of 2019 than Wall Street had anticipated, prompting analysts to scrutinize its margins on cars. In a financial call held Wednesday, that scrutiny took form around... 
You don’t have to look long to see the counterculture influences that persist around Eugene, Oregon. Last week, mostly avoiding tailpipe emissions and driving the 2019 Porsche Cayenne E-Hybrid on plug-in charge, we quietly cruised past the eco-villages, community gardens, and co-ops that are a permanent fixture there, to the tie-dyes and...
