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...

The new sodium metal halide battery is a high-temperature electric battery that uses molten salts as an electrolyte. This new technology offers both high energy density through the proper selection of reactant pairs as well as a high power density by means of a high-conductivity molten salt electrolyte.

For millions of years, trees have had the whole energy thing down. Grow a few thousand leaves, capture a little sunlight and suck some water out of the ground, and voila! you have energy to grow and reproduce!

On November 15, 2011, The Environmental and Energy Technology Council (E2Tech) and its partners held an event heralded as the launch of Maine's Clean Tech Corridor. While it was safe to witness this launch from a mere distance of 5 feet or so, the potential economic power of the Clean Tech Corridor may be formidable, indeed.
