We just wrote about the new LED streelights in Ann Arbor. Now we find these self-contained streetlights that generate 100% of their power from the sun and the wind. During the day, solar power is stored in a battery at the base of the light pole. At night, they illuminate while continuing to generate power […]
The “Energy Plus” office building, to be located outside of Paris, is designed to produce all its own energy for heating, lighting and air conditioning.
