Wind energy is a renewable source of energy that does not produce any harmful by-products. People capture wind energy by using turbines. As the wind turns the blades of a turbine, it generates energy to power a generator, which turns the energy into electricity.
People who choose to install wind turbines may save money on energy costs. They may also be able to sell energy to a power company if they generate more than they need. The downsides of using wind energy are that turbines cost a lot of money to install and can be damaged by severe weather. Some people consider them noisy and unsightly. Also, not all locations have winds strong enough to be suitable for generating electricity.
