Ocean Wave Energy is the future of energy generation in India as it could result in most economic green process with minimal carbon emission. The power consumption and power generation of India lagging behind share of renewable energy because of increasing power requirement. Further few wave energy techniques have been discussed briefly, which focuses on potential scope research and development in the future. The wave energy technology is not so popular if current status of energy generation in India is taken in account. In case of India, there is tremendous scope for the energy from the ocean as India has a vast coastline and numerous islands in Bay of Bengal and Arabian Sea. This paper represents a basic review of the technology used in wave energy conversion and discusses its magnitudes in India.
