Summary:
Fossil fuels have long been the world's energy source, but it wasn't always that way. Ancient Eastern cultures developed the first known wind mills for drawing water and grinding grains into flour. The modern three-blade, computer-controlled Wind Turbine does what all wind turbines have always done – harness the energy from the earth's constant flow of air. This program explores wind power's alternative energy production in today's oil-dependent economy - how it works and the environmental factors that scientists are researching.
