With the cost of fuel today, there is much talk about alternative energy. One alternative energy source that is being talked about is wind energy, and how efficient wind farms are. Making use of wind as a source of energy means having a renewable power that is fantastically clean. Solar energy is the real source of wind power, since wind is caused by variations in ground temperature and the ground is heated by the sun. The wind is thus channeled to produce electrical energy.

There are several countries that have embraced the use of wind farms as a way to effectively amass energy from wind. Numerous different wind turbines, along with their propeller-like blades, are set up in a specific spot, in order to amass the wind's power. Wind farms, as a result of the large number of turbines working together, have the capability to make energy in great quantities. The potential of wind farms will become obvious when you understand how they work. Wind energy starts with the wind turning the blades of the turbine, which are linked to a central shaft. The shaft is connected to a generator, which generates electric power from the turning action of the shaft. It employs the same principles as hydropower generation, except that wind power as opposed to flowing water is utilized.

One turbine by itself will not generate energy for more than a house or farm, so it takes more than one to generate energy for a huge area. When the ability of a turbine is magnified by having groups of them, like you see on a wind farm, the combined amount of electric power that can be created is very big. The electricity produced is sufficient for running a whole community when you store it on an existing utility grid or in special large-scale battery cells. These days wind turbines are so high-tech that they can utilize wind coming from any direction, even when it is from inconsistent, variable angles.

The efficiency is raised also when the turbines are taller, or if they have bigger blades. With so many factors that affect how well a wind turbine will function, determining its production efficiency is not a simple task. As Adam Zawartko states, there is no constant, when it concerns wind farms, since they deviate so much in terrain, size of turbines, and the amount of wind. Nonetheless, the standard turbine converts approximately 20% of the power in wind to electrical energy. Wind turbines are at their most cost-efficient in wind speeds of from 5 to 20 miles an hour.

While it is not as constant as solar, wind power is more efficient, estimated as 20% efficient versus solar at roughly 14%. Wind is one of the more favorable kinds of renewable energy, and benefits from technology getting better all the time. As a type of alternative energy source, it is considered as increasingly crucial, but is not yet employed worldwide. One of the leading governments in the use of wind power is Germany.
