Nobody has ever made solar power at night yet, nor wind power when she's in irons. So using these renewable power rigs means having to store some of the energy somehow for low-production times.

Energy Storage: How Erratic Energy Sources can Meet our Demands

We can store energy in many ways. To use renewable energy sources, whose supply is intermittent compared to our demand, we need to store energy at times of peak production for use when demand is high. To explore the ways we can store energy, read on...

Roadways of the future may not be paved by asphalt. A creative new alternative to paving roadways without asphalt is glass! Solar roadways could collect heat and harbor the energy. Incredibly, these roads would be able to pay for themselves. But is it possible to drive on glass? In addition, do you think it can catch on in Maine?

Projects funded by the U.S. Department of Energy's (DOE's) Solar Energy Technologies Program (SETP) are developing new forecasting tools that can help utilities plan for reductions in solar photovoltaic (PV) power outputs and determine how to move or add generation resources in the future.  The first project, funded by SETP with cost-share from the California Energy Commission, is managed by the University of California at San Diego's (UCSD's) director of strategic energy initiatives, Byron Washom. It utilizes the campus' own microgrid as the project's high-tech laboratory.

The newest and biggest technological innovation for electric vehicles is the lithium-ion battery, which was recently explored by the EERE's Energy Blog when it travelled to Michigan for the "Electrigying the Economy-Educating the Workforce" workshop in April.

The Shoals Marine Laboratory, a field station cooperatively run by Cornell University and the University of New Hampshire, is located on Appledore Island off the NH and Maine coasts. From 2007- 2010, they installed both wind and solar power to reduce their need for diesel-generated electricity.

Welcome to Maine’s conversation about energy storage. Remember from high school physics that all energy is either kinetic or potential?  Anything that holds potential energy is storing it for later use, when it will be converted to kinetic or working energy.  Food is one example: Solar energy is stored in plants until we eat them (or eat the animals that ate them).
