Ocean energy technology development - The challenge of this millennium

Abstract

Ocean is a reservoir of energy. It is not only pollution free but also renewable.Development of suitable technologies for power generation from different forms of ocean energy is challenging. R & D works around the world has improved the hope for technical feasibility of ocean power generation. Increase in the cost of fossil fuel is indirectly helping more focused research work in this area. It is hoped that more pilot plants will be installed at various ocean locations which may lead to commercial ocean power exploitation.This editorial note discusses the different forms of ocean energy, physics of energy conversion, and the technical challenges involved in the technology development.
