Wave Energy
Introduction
Wave Energy is the energy generated through
the power of the ocean wave. It is a renewable energy (i.e. it cannot be
depleted) as long as we have ocean wave. It therefore provides a good
alternative to the traditional energy sources - the
fossil fuels.
Wave, like most other renewable energy
sources such as solar, wind etc, derives its energy from the Sun (i.e.
from solar energy). Sun heats up the air and the differential heating
results in wind. When wind blows over the ocean, it creates the wave
energy.
Besides being renewable, wave energy is
clean. It does not generate pollutions as fossil fuels do. Consequently,
it does not generate greenhouse gases (CO2, methane (CH4) etc. responsible
for global warming, nor SO2 responsible for acid rain). Adopting wave
energy is therefore environmental friendly.
Scientists believe that, if properly
harnessed, wave energy alone can meet the energy requirements of the
entire World, since about 71 percent of the World's land mass is covered
by water. The wave energy from this vast amount of water has been said to
be capable of producing twice the amount of energy being currently
generated in the entire World (World
Energy Council).
