Wave and Tidal Generation Devices

The potential of wave power lies in waves' kinetic energy. Waves have a far greater energy density than wind or solar and can generate between 24-70 kW per meter of wave. The global tidal energy potential is estimated to be 3 TW, with approximately 1 TW in comparably shallow waters. The challenge for the development of marine energy converters (MEC) is to achieve an investment cost and rate of return that will make marine energy devices viable, compared to other sources of electrical power.
