Alternative Power for You

Definitely, there are two types of wind-powered generators: one horizontal and one vertical. Horizontal wind generators have blades similiar to airplane propellers. While vertical wind generators, these appear to be massive in size, have blades that move from an apex on a base. Also they are only a small percentage of wind power generators producing energy today.

To produce electricity with the wind, think of it as being the opposite of a motorized fan that uses electricity and with revolving blades forcing the air to move. Wind turbines are turned by the pressure of the wind to provide motion to an array of blades and the mechanical energy made by these blades is then converted into electrical energy by a generator.

During the day land absorbs heat faster than water. So as a result, air expands and moves up, creating a vacuum for fresh air to move in from the environment to take its place and vice versa is done at night when the air cools faster over land than water. Wind power is a cost-effective renewable energy in many parts of the world. Wind is almost a prefect energy, wind generators produce no pollution and no fuel is burned. The only environmental shortfall of wind turbines may be their consequence on wild bird populations.

Wind as a renewable energy source.

Since the beginning of time, people have tried to controll the wind for power. Over 5,000 years ago the Egyptians first used wind for sailing ships on the Nile. Not long after, people constructed windmills to grind wheat and other grains. The first known windmills were in Iran, called Persia then. Thousands of years later, Holland has become famous as a country of windmills and tulips.

Nowadays, wind is widely accepted for creating electricity and as a renewable energy source because the wind will be here until the sun stops shining. Like the windmills of old, these days, wind power employs blades to convert the kinetic energy held in the wind. The wind flows over special styled blades producing force that in turn causes them to spin. The spinning blades are attached to an electric generator producing electricity to be used or stored.
