New technique could harvest more of the sun’s energy

December 1, 2014 8:32 am | by Jessica Stoller-Conrad, Caltech | News | Comments

As solar panels become less expensive and capable of generating more power, solar energy is becoming a more commercially viable alternative source of electricity. However, the photovoltaic cells now used to turn sunlight into electricity can only absorb and use a small fraction of that light, and that means a significant amount of solar energy goes untapped. A new technology epresents a first step toward harnessing that lost energy.

Matched hybrid systems may hold key to wider use of renewable energy

December 1, 2014 8:09 am | by David Stauth, Oregon State Univ. | News | Comments

The use of renewable energy in the U.S. could take a significant leap forward with improved storage technologies or more efforts to “match” different forms of alternative energy systems that provide an overall more steady flow of electricity. Historically, a major drawback to the use and cost-effectiveness of alternative energy systems has been that they are too variable. This lack of dependability is costly and inefficient.
