We
have harnessed wind power since a long time. Sailing
ships had toiled the seas with wind on their sails for
ages while the early Egyptians used wind power in
pulling water and grinding corn with the help of massive
windmills. However, the first wind powered mill in
Europe was commissioned by Prof. James Blyth of
We
however managed to forget about wind power for all these
years till only recently when people realized their
blunder in depending on fossil fuelled power that had
literally polluted the world to the core. Moreover,
these thermal power stations are the biggest
contributors of Carbon Dioxide or CO˛ that destroys life
and the environment. It is indeed a welcome sign that
people are now keen on replacing fossil fuel generated
powerhouses with wind generated power. Wind as a
renewable natural power is today extensively used to
generate electricity in innumerable homes while large
wind parks are supplying power to national
grids.
Known
as wind turbines, these revolutionary mechanisms come in
many different shapes and sizes, generating power for
homes that range from 5 to 15 kilowatts while utility
scale systems provide 300 to 1,000 kilowatts of
electrical power. In fact they are so numerous now in
most
Information
on wind power
may remain incomplete if we fail to see wind as another
form of solar energy. Though sounding a bit weird, it
nevertheless is true since wind power is largely
dependant on the sun’s heat rays that creates
temperature difference between the land, sea, desert as
well as air. For instance, when one surface area on the
earth heats up faster than its adjoining surface, the
air above it expands, loses its normal density and
propels up, leaving a temporary void. As a result of
this, the atmospheric pressure in that area abruptly
drops (a fact that can be checked with the help of a
barometer), urging the neighboring cooler air to rush
in, filling the void. Popularly known as Thermal, this
common phenomenon is mostly responsible for wind
sessions. As a matter of fact, this is one of the
primary reasons for wind gathering its force or
power.
Wind
power and its ability to generate electricity depend on
several factors, one of which concerns its resources
that also includes it average speed or velocity. For
instance, a very weak wind will not be able to turn the
blades of a wind turbine and so no electricity will come
out of it. However, to overcome this problem one can
always take the help of the Windpower map of the
Get complete information on wind power and how to set up a system at home to make your own safe and clean energy with the help of a manual. This manual teaches you where best such a system works in the home, helps you learn how to set it up and wire the system and also makes you know where you can get cheap parts from. Plus you can also learn about the safety precautions. There are numerous ecological and financial benefits and so wind power as an alternative cannot be ignored anymore.
