The Earth itself can be thought of as a giant battery. All the solar radiation that is absorbed by the planet as short wave solar energy is then radiated back out to space every night as long wave radiation. In most areas, the sub soil is kept at a constant 50F/10C, no matter the time of year.

The wind power industry has been transformed in the 1990s by dramatic breakthroughs in efficiency, economy, and adaptability. One of the most exciting developments in the production of renewable energy at home is the use of micro-turbines.
