Drivers, start your batteries: electric cars to race
Motor racing is set for an electric makeover that will see a new generation of green cars speeding at 220 kmh (138 mph) around urban racetracks—at least until their batteries run out.
Microgrids: So much more than backup energy
(Phys.org)—Most Americans don't have to think much about energy reliability. We plug in a computer and it powers up; we flip a switch and the lights come on.
US carbon emissions in surprise drop
US emissions of carbon dioxide blamed for climate change fell in 2011 and have slipped to a 20-year low this year as the the world's largest economy uses more natural gas and less coal, data shows.
Self-charging battery both generates and stores energy
How affordable is alternative energy?

Replacing coal with natural gas would reduce warming: study
A debate has raged in the past couple of years as to whether natural gas is better or worse overall than coal and oil from a global warming perspective. The back- and-forth findings have been due to the timelines taken into ...
New biofuel process dramatically improves energy recovery
A new biofuel production process created by Michigan State University researchers produces energy more than 20 times higher than existing methods.
Study on fungi helps explain coal formation and may advance future biofuels production
A new study--which includes the first large-scale comparison of fungi that cause rot decay--suggests that the evolution of a type of fungi known as white rot may have brought an end to a 60-million-year-long ...
New loo turns poo into power
Scientists from Nanyang Technological University (NTU) have invented a new toilet system that will turn human waste into electricity and fertilisers and also reduce the amount of water needed for flushing by up to 90 per ...
