How reliable is wind powered electricity?

The reliability of electricity produced by windmills depends on the reliability of the winds. In some places the wind tends to blow steadily for much of the time, but there are always times when the wind does not blow. It is therefore necessary to have reliable backup generating capacity, which could be oil, coal, nuclear, or geothermal. Water power produced by hydroelectric generating stations taking the energy from flowing water are generally reliable, but in times of extreme drought can lose a large fraction of their capacity.

Of course, all forms of power generation can fail due to mechanical or political problems (people have protested nuclear power plants and caused them to shut down), so excess capacity is always needed.

In my opinion nuclear power is the safest, cleanest, and most reliable, but it fails politically.

I am not sure what you mean by the term "reliable". As long as the wind keeps blowing the wind mill will keep on generating energy. That energy, assuming it is electrical, is stored by some mechanism such as a battery, or other means.

Vince Calder

As reliable as the wind.
