Today about 87 percent of the world’s energy consumption relies on nonrenewable energy sources such as oil, natural gas, and coal. The burning of these fossil fuels releases pollutants into the atmosphere and can result in environmental damage. An abundant and promising source of renewable energy exists in the forms of wave, tidal, marine current, ocean thermal energy conversion, and salinity. This publication describes nine different types of wave-energy devices currently under development or nearing completion.
