Wave energy is the most promising form of
ocean energy which during extraction process does not
emit carbon dioxide or produce any waste. It creates no
noise pollution and is environmental friendly. Unlike
other renewable energy sources, it is more predictable.
Till date, only a small part of abundance energy stored in
waves has been utilized. This large untapped source of
energy could meet the global energy demand if technical
and other barriers are overcome and its cost is thereby
reduced. This paper presents an overview in respect of
current status of research and development in harnessing
of wave energy. The article focuses on available
technology to extract power, its estimated potential and
current exploitation level both globally as well as in India.
Further, barriers and obstacles in its deployment and
commercialization and perspective of the cost of
generating power have also been discussed.
