Energy Reviews

Renewable energy has four important sources mainly- solar, hydrogen,
biomass and wind. Wind power seems to have maximum potential in terms of
investment and development. This new definition of energy has generated
interest in people and government because of its cost effectiveness in
generating electricity. Some of the developed countries implementing
wind power on a huge level are Germany, India, Spain, China and America.
The most important feature of this energy sources is that these sources
are replenish-able and never run out. The highest amount of energy
comes from the Sun and this energy is used in heating and lighting up
the house and business premises.

In present scenario, where the level of pollution is at its peak level
and we are breathing polluted air which is not only polluting our
environment but also creating global warming effects. Therefore, using
renewable source of energy is important not only it has environmental
benefits but also saves thousand bucks. These energy power plants are
clean and have low environmental effect in respect of conventional
technologies.

With growing awareness, people have now started to
concentrate on solar power system and wind turbines. The wind turbines
are placed on high tower to capture as much wind as possible. The
turbine capture wind with the help of blades and in each turbine, three
blades are placed.

As it is already told that renewable energy
is eco logical and it can be restored, this is considered to be the best
alternative of electrical source. Like renewable source of power, other
power sources do not use natural resources and instead of it, they use
some kind of materials that prove harmful for global environment. This
new source of energy helps in eliminating waste materials and save our
environment. With the growing awareness of people, if each nation
focuses on developing renewable sources, then we can eventually decrease
our dependency on fossil fuels. In recent times, scientists have
discovered some more sources like the use of methane which can be used
as a source of power. Recycling of garbage also helps to generate
electricity. In fact, today, the scientists are not just only use
renewable energy but also take the step to decrease the waste in the
world.

Renewable power of energy provides steam and heat for industrial
purposes. In respect of homes, these are mainly used for transportation
and heating purposes. Today, the growing advancement of science is of
great help in maximizing the use of renewable sources in generating
electricity and power. The green technology is a waste energy system
that helps in producing green energy without polluting the environment.

There are mainly two categories of solar technology. One is passive
solar design that needs no other energy. Green roofs, solar chimneys,
solar architecture are example of passive solar energy. Another category
is active solar that converts solar energy into other forms like
electricity and heat. Concentrated solar power and photovoltaic are
examples of active solar.
