Fuel for Thought

Coal is the world's primary source for electricity production. Power plants that use coal burn it to heat water and produce steam. The steam spins a turbine, which rotates a shaft in a generator. The generator converts the energy to electricity.

We need energy to produce electricity. Electricity powers everything from small appliances to huge industrial machines. We use electricity in our homes, schools, and businesses. Where does electricity come from? We generate it from several energy sources. According to the World Wind Energy Association (WWEA), the world currently generates 1.3 percent of its electricity usage from wind energy.
