We have been harnessing the wind’s energy for thousands of years. But we’ve been using it to generate electricity for only the last few decades. Initially, wind power was considered a science experiment at best. But not anymore. Today, it’s the cheapest form of renewable energy. In fact, wind power is the cheapest form of energy, period. Wind is cheaper than nuclear power, coal and, now, even natural gas. Until 10 years ago, utilities were the only buyers of wind-generated electricity. Since then, a few things have happened to change the demand for wind. Many climate-conscious companies began to look for ways to reduce their carbon footprints. Replacing fossil fuel-generated power with renewable energy started to rise in popularity. As it turns out, there were a lot of wind generators looking for more customers. And corporate America was looking to buy a lot of renewable energy.
