Humans have been using wind power for at least 5,500 years to propel sailboats and ships. Wind power provides a renewable source of energy that can generate electricity and power homes without the need for burning fossil fuels. Modern windmills have three streamlined blades to capture wind energy and convert it into electrical power, helping power homes and reduce energy costs, especially for those who cannot afford other power sources. Wind power is particularly suitable for countries with windy climates.
