Over time, windmills began to be built bigger and became more ornate. In fact, some even became homes for the millers who owned and worked in them. During the 1970s, shortages of oil for generating electricity led to interest and research in wind power. By the early 1980s, advances in technology had made it possible for wind turbines to produce large amounts of electricity. Some states, like New York and California, installed thousands of the new wind turbines, which are still in use.
Windmills are perhaps one of the future answers to generating electricity.
