Abstract:
Increase in human population has increased the demand for more energy. Technical improvement in
transport and electrical appliances gives a lot of facilities to our life nowadays. Still we need to generate
or convert this energy. Energy generation based on conventional technologies is always accompanied by
environmental pollution. It gives overheating and greenhouse effects that later result in biosphere
degradation. Nowadays sea wave energy is being increasingly regarded in many countries as a major and
promising resource. It is renewable and environmentally friendly. In this paper wave parameters related
to wave energy is analyzed. Then the paper describes the development of many different types of waveenergy
converters. Several topics are addressed; the characterization of the wave energy resource, range
of devices and how such devices can be organized into classes.
