There are many different types of electrical power stations. Wave energy is intended to decrease use of older, traditional power stations, such as those that burn oil, gas, or coal, or nuclear power plants. These types of power stations are costly to run and pollute the environment. But even hydroelectric power plants have been criticized by some as being harmful to the environment. Have students compare the average electric bill in your state with the average bill in California.
Ocean waves have other ways in which they transmit energy.
