NASA researchers who developed a new way to power robotic underwater vehicles believe a spin-off technology could help convert ocean energy into electrical energy on a much larger scale. The researchers hope that clean, renewable ...
Two decades ago, a section of the Amazon rainforest was flooded for a dam that currently produces little electricity. Engineers now see that artificial lake as an ideal surface for floating solar panels.
(AP) -- The manager of most of the electricity in the Pacific Northwest is running such a surplus of power from hydroelectric dams that it put wind farms on notice Friday that they may be shut down as early as this weekend.
Giving new meaning to the term "server farm," a team of Hewlett-Packard researchers has come up with a plan for combining cow chips and computer chips to build an environmentally friendly data center -- powered by manure.
(Phys.org)—Americans used less energy in 2011 than in the previous year due mainly to a shift to higher-efficiency energy technologies in the transportation and residential sectors. Meanwhile, less coal was used but more ...
Widely hailed as 'green' sources of renewable energy, hydroelectric dams have been built worldwide at an unprecedented scale. But research from the University of East Anglia reveals that these major infrastructure projects ...
Brazil's Belo Monte hydroelectric dam in the heart of the Amazon will have fewer environmental effects than fossil-fuel alternatives and will be cheaper than other renewable energy sources, state media said Sunday.
China's Three Gorges Dam has caused a host of ills that must be "urgently" addressed, the government has said, in a rare admission of problems in a project it has long praised as a world wonder.
Scientists have found that some reservoirs formed by hydroelectric dams emit more greenhouse gases than expected, potentially upsetting the climate-friendly balance of hydroelectric power.
Ethiopia has begun diverting the Blue Nile as part of a giant dam project, officials said Wednesday, risking potential unease from downstream nations Sudan and Egypt.
