Wind resistance: Analysis suggests generating electricity from large-scale wind farms could influence climate
Wind power has emerged as a viable renewable energy source in recent years -- one that proponents say could lessen the threat of global warming. Although the American Wind Energy Association estimates that ...
Some suggest it's time to rethink which direction we point our solar panels
Researchers discover source for generating 'green' electricity
University of Minnesota engineering researchers in the College of Science and Engineering have recently discovered a new alloy material that converts heat directly into electricity. This revolutionary energy conversion method ...
New materials turn heat into electricity
Most of today's power plants--from some of the largest solar arrays to nuclear energy facilities--rely on the boiling and condensing of water to produce energy.
Liquid battery could charge green energy
Engineering professor Donald Sadoway on Thursday used an old-school chalk board at the prestigious TED gathering to write the formula for a liquid battery that could one day cut the need for new power plants.
