First-ever global life cycle assessment of renewable energy future
A future where electricity comes mostly from low-carbon sources is not only feasible in terms of material demand, but will significantly reduce air pollution, a study published in the today's Proceedings of ...
Fully renewable electricity could be competitive
(Phys.org) —A carbon price of between $50 and $100 per tonne of carbon dioxide would make coal-fired and gas-fired power less economical than renewable electricity, a UNSW study shows.
Researchers use real-world data to model the effect of more solar on the grid
American electrical utilities do a pretty fantastic job of getting us electricity when we need it. In 2006, the power was out on average for just 0.03 percent of the year in the United States. But right now, ...
New research warns world to prepare for blackout
(Phys.org) —Living without electricity in today's technological world may be difficult to imagine. Yet the reality of living without computers, mobile phones and entertainment systems, and managing a transport ...
Company unveils small personal-sized hydroelectricity generator
Google offers big prize for small power box
Google is offering a million-dollar prize for a breakthrough that would make solar or wind generated electricity more enticing for everyday uses.
Storing green electricity as natural gas
Renewable electricity can be transformed into a substitute for natural gas. Until now, electricity was generated from gas. Now, a German-Austrian cooperation wants to go in the opposite direction. In the future, these researchers ...
European wind power output tipped to treble by 2020: report
Energy producers expect European wind power generation to triple by 2020, with tens of thousands of new, ever-bigger wind turbines springing up, an industry body said Tuesday.
Solar and wind energy may stabilise the power grid
(Phys.org)—Renewable energies such as wind, sun and biogas are set to become increasingly important in generating electricity. If increasing numbers of wind turbines and photovoltaic systems feed electrical ...
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.
China a surprise leader in clean energy: study
The world's top polluter, China, is a surprise leader in clean energy efforts, a study showed Tuesday, outstripping the United States and Japan and leaving Australia lagging far behind.
Americans using more fossil fuels
American energy use went back up in 2010 compared to 2009, when consumption was at a 12-year low. The United States used more fossil fuels in 2010 than in 2009, while renewable electricity remained approximately ...
Toward a networked energy future
February 1, 2050, is a good day for German electricity consumers. The breeze off the north coast is blowing so strongly that offshore wind farms and the wind turbines on land are running non-stop. Since it's ...
Two-thirds of the world's new solar panels were installed in Europe in 2011
Europe accounted for two thirds of the world-wide newly installed photovoltaic (PV) capacity in 2011, with 18.5 GW. Its overall PV capacity totalled 52 GW. The yearly electricity produced by PV could power a country with ...
