Energy generated from wind has both advantages and disadvantages. What is true about wind energy?

No greenhouse gases are given off by wind power, but payback for construction takes many years.

Some erosion occurs around the towers of wind turbines, but electrical fires are highly unlikely.

There is enough wind power in the U. S. to drive the entire country, but aesthetic considerations cause some people to oppose its use.

Modern turbines are safe for birds and bats that fly in the area but can reduce the number of crops grown on farmland.
