The U.S. state that takes climate change most seriously—California—has unanimously approved new rules dubbed the Advanced Clean Cars program to lower carbon emissions, reduce oil dependence, mitigate health impacts from pollution, and save …

FirstEnergy says it would not be cost-effective to install scrubbing technology at aging plants to meet new federal emissions rules.

Scientists have devised a new way to produce ethanol directly from seaweed, offering the potential to generate biofuels that don’t compete with terrestrial food production and won’t suck up scarce freshwater, reports a study published today in Science.

Manhattan started out with a mere handful of public charging stations for electric vehicles. It now has more than 50.

As humans we take many things for granted. When we come down with a sore throat, a fever, or the dreaded stomach flu, we drag our aching bodies into our cars and visit the doctor. Animals have no such luxury. Instead they have mastered evolution and h…

In July, at the Association for Computing Machinery’s MobiSys conference, researchers from MIT and Princeton University took the best-paper award for a system that uses a network of smartphones mounted on car dashboards to collect information about t…

MIT researchers have found a way to improve the energy density of a type of battery known as lithium-air (or lithium-oxygen) batteries, producing a device that could potentially pack several times more energy per pound than the lithium-ion batteries th…

President Obama has unveiled a deal on vehicles, fuel and CO2.

“Zero emissions” is a tricky phrase. Electric vehicles produce zero emissions at the tailpipe, but more often than not there are emissions at the power plant. The only way to have a truly zero-emissions EV is to get your power from a renewable source l…
