Electricity is the most common form of power used in the world. In order to provide electrical energy to users, power companies build power plants. Electrical energy is usually generated by a spinning magnet called a turbine. The turbine is moved by wind, water, burning fuel, or some other energy source. This energy then travels through power lines to homes, schools, and businesses. The United States has about 7,700 power plants. Throughout the world, there are approximately 62,500 power plants. Another way to produce electrical energy is to use a solar panel. Solar panels use light energy from the sun to produce an electric current. This energy source can work on a small scale, such as producing energy to power a single street light. It can also work on a very large scale. A large solar powered facility uses thousands of large panels to produce enough energy for a small city, READING CHECK Sequence Number the order of events involved in producing electric energy and supplying it to a home.​
