Renewable Wind

The wind is clean, it's renewable, and enough of it blows across our planet to meet everyone's energy needs many times over. In fact, just one giant wind turbine can turn enough wind energy into electrical energy to power hundreds of homes.

Unless the wind isn't blowing, of course. Then those turbines do nothing. So can we rely on wind, clean and renewable as it may be?
