Question

Why would the wind not be a practical source of energy?
Sources would be helpful, because I need two reasons.

Answer 1

Bob is right. As a matter of fact, it is among the most practical sources of energy. Wind was the main source of power for ships for many centuries, and windmills have been used for many centuries to pump water and perform other work.

With highly efficient modern generators, it's probably the best source for electricity in many areas when everthing is considered.

Answer 2

Wind IS a practical source of energy.

The power contained in wind gets more powerful by the function of the CUBED value as the speed increases, so wind at 10 miles an hour has value 2, wind at 20 miles an hour has value 8 (for example)

Look up Google for Lamar Colorado wind and read about the cost of electricity NOW in production there from 4 large wind turbines. The blades are 115 feet long alone!

Lots of info on wind on the web. Even a place on our website captioned below. Good luck.

Answer 3

1)... times when wind would NOT be blowing...

2)... times when wind would blow so hard it would damage the turbine or wings....
