The overall carbon emissions associated with electric cars decrease as the electricity used to recharge them gets cleaner. And the latest statistics from the International Energy Agency (IEA) will be good news indeed for electric-car drivers. Last year saw record growth in renewable energy, according to the IEA, which surpassed coal to become the... 
Among U.S. states, California continues to lead the way in policies that aim to cut carbon emissions. The Golden State has ambitious emission-reduction targets, and has implemented policies for both transportation and energy to achieve them. But the city of Santa Monica has just done something unprecedented—even for California. DON'T MISS... 
The failure of cellulosic ethanol may prove beneficial to oil giant Royal Dutch Shell. Cellulosic ethanol was seen as an important component of mass ethanol adoption because it is made from non-edible plants. But despite the hopes of ethanol advocates and policymakers, cellulosic sources never materialized in significant quantities. DON'T MISS... 
Owners love them, but modern electric cars have not made a large dent in sales of internal-combustion cars since becoming widely available five years ago. In fact, but for a few exceptions, electric cars essentially wouldn't exist without legislation aimed at lowering transportation-related carbon emissions. Tesla's success in raising the profile... 
The U.S. Department of Energy (DOE) loan program that became a lightning rod during the 2012 presidential election is now turning a profit. The program became infamous for backing solar company Solyndra, which later went bankrupt. Three years after Soyndra's failure, though, the program is now in the black. DON'T MISS: Carbon emissions from U.S... 
Back in 2007, the Energy Independent and Security Act included a Renewable Fuel Standard intended to boost adoption of lower-emission alternative fuels. It mandated increasingly-large amounts of ethanol to be blended with the U.S. fuel supply. Just under a decade later, the legislation has attracted criticism from both opponents of ethanol and the... 
Critics of the renewable-energy industry argue that it's unfair that energy sources such as wind and solar often benefit from government subsidies. But the volumes and amounts of subsidies received by the fossil-fuel industry are substantial, as new analysis shows. In December 2013, the U.S. and China announced plans to undertake a reciprocal peer...
