Wind
Power
Wind is a form of
solar energy. Winds are caused by the uneven heating
of the atmosphere by the sun, the irregularities
of the earth's surface, and rotation of the earth.
Wind flow patterns are modified by the earth's terrain,
bodies of water, and vegetation. Humans use this
wind flow, or motion energy, for many purposes:
sailing, flying a kite, and even generating electricity.
The terms wind energy
or wind power describe the process by which the
wind is used to generate mechanical power or electricity.
Wind turbines convert
the kinetic energy in the wind into mechanical power.
This mechanical power can be used for specific tasks
(such as grinding grain or pumping water) or a generator
can convert this mechanical power into electricity.
Wind power makes
a wonderful power source if you live in a good wind
area. Wind can be used as back up power in the event
of a power outage or if you have enough energy can
power the entire house. It is an economical and
excellent source of electricity if you live outside
of the power grid and is environmentally friendly.
Typically, at an
average annual wind speed of 12 MPH the a wind energy
system will produce about 4800 kWh of energy per
year. That will reduce an average family's bill
by up to 40% per year (at an average annual use
of 12,000 kWh/year). There are lots of full service
windmill installation
companies as well as do-it-yourself kits on the
market.
