Abstract
Wave power presents as the movements of water particles close to the ocean surface. The energy intensity depends on the height and frequency of waves. A large amount of wave power in random sea motivates us to think of using ocean wave energy for generating electricity. We use wave energy converters (WECs) to change potential kinematical energy of sea waves to electrical energy. Waves in the ocean have a vast amount of renewable energy. This makes the ocean a renewable source of power in order of terawatts (TW). The global power resource represented by waves that hit all coasts worldwide, has been estimated to be in the order of 1 TW.
