Alternative Energy Sources

by Anna Williams

What is alternative energy and what are its forms?


Conventional sources of energy are getting depleted fast,
which leads to a need for renewable energy sources. There are quite a
few promising sources that can be considered.

The term "alternative energy" can refer to any energy source
that doesn't burn any fuel or involve the splitting of atoms. Because
of the pollution caused by our standard energy supplies, there's a
growing interest in finding good alternative energy sources. Hopefully,
this doesn't stop at wishful thinking.

Renewable energy sources, such as solar power, geothermal
energy, wind power, tidal power, and hydroelectric power, are being
seen as possible replacements for our conventional and less clean
energy sources. Technology is still being researched and developed, to
fully maximize their efficiency.

Solar Power

Among the alternative energy sources in use today, solar
energy is possibly the most well known, especially in places where the
sun is always shining. The Earth receives a considerably amount of
solar energy on a daily basis, but only a small percentage of it is put
to good use. It is used to power heating systems for homes and
businesses, to run cars, and to operate space satellites. And as
research advances, the future looks bright for solar energy.

Geothermal Energy

Geothermal Energy is produced by the internal heat of the
Earth, which could be used to generate steam to run a steam turbine.
The turbine would then generate electricity. It could provide
supplementary power even if not functioning as the primary source.

Wind Power

Wind power is one of the cleanest forms of energy production,
able to generate electricity without harmful byproducts. The
disadvantage is that its use greatly depends on the weather conditions
in a particular area.

Hydroelectric Energy

Tidal and hydroelectric power share the same basic principles
in how they generate electricity. They utilize the force of the water's
movement, and convert it into electric power. In hydroelectric plants,
water is usually stored behind dams. As soon as the water has been
released at a high pressure, it is used to turn the turbine blades
below, which are then used to generate electricity.

As technology advances, we become increasingly more capable of
harnessing the full potential of our clean and renewable energy
sources. It is vital that we continue this research and development,
and eventually put an end to the use of fossil fuels or other polluting elementsFree Articles, with their
harmful effects on the environment.

Alternative forms of energy and use

I would be interested in hearing of other less-known types of alternative energy. Does the above include harnessing wave power? I would think that would be an easy adjunct to the already-existing oil platforms.
