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?
Alternative energy sources that are cost-competitive with fossil fuels may be closer than most people realize. Recent renewable energy research has shown that solar, hydropower, wind and other alternative sources are closing ...
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 ...
Scientists solve structure of important protein in energy storage of cells
(Phys.org) -- Scientists at Trinity College Dublin, using a highly specialised crystallography technique have solved a large protein structure that will increase our understanding of energy generation and storage in cells. ...
Report slams new coal power station in India
An independent report into a huge coal power station being built in energy-starved India on Tuesday called for construction to be halted immediately due to environmental damage.
Sea waves as renewable resource in new energy converter design
Sea waves are a renewable and inexhaustible resource found in abundance across the planet. But efficiently converting sea wave motion into electrical energy has been challenging, in part due to the difficulty of compensating ...
No more cloudy days for solar
For a country with so much sunlight, some might think Australia has been slow to adapt its electricity generation mix to include solar power. One of the main reasons for this is solar intermittency.
Renewable energy costs falling: agency
Power from renewable energy sources is getting cheaper every year, according to a study released Wednesday, challenging long-standing myths that clean energy technology is too expensive to adopt.
Compact and flexible thermal storage
Biogas plants, combined heat and power plants don't just generate electricity, they also produce heat. However, unlike the electricity they yield, the heat generally dissipates unused. A new technology is ...
Panasonic to begin mass-production of long-life lithium-ion battery system for solar-powered homes in Europe
Panasonic Corporation announced today that it will start in June mass-production of a compact, secure and long-life lithium-ion battery system the company has developed for European homes. This marks the first time for the ...
Apple says data center will be all green
Apple says its $1 billion data center in Maiden, N.C., will include a second large solar farm to help power the site entirely by renewable energy by the end of this year.
Researchers generate electricity from viruses
Imagine charging your phone as you walk, thanks to a paper-thin generator embedded in the sole of your shoe. This futuristic scenario is now a little closer to reality. Scientists from the U.S. Department of Energy's Lawrence ...
