Do You Have All The Information You Need To Choose A Wind Turbine?
Oct 9, 2009 Save Money
Home wind turbines typically do not deliver their maximum rated output.Why is this the case? Simply because surface and near-surface winds are generally neither strong nor consistent enough to rotate the propellers at their “best RPM range” all of the time. Raising the turbine to higher elevations usually increases the average current output because wind strength typically increases at higher elevations/altitudes although wind directions still remain variable.
The same wind supply inconsistency makes wind power inappropriate as a fixed, demand-driven source of energy unlike coal- or diesel-burning power plants that can be turned on or off according to consumer needs. This situation should change, however, if superconducting charge (or current) storage devices become cheaper. Very large-capacity battery banks, or very large batteries, or super capacitors should also be designed for the purpose of storing large amounts of electricity.
Small wind turbine generators have been around in the US since the 1920s. The Jacobs Wind Electric Company consistently sold 1- to 3-kW wind turbines to consumers in North America and around the globe until the US rural electrification grid came fully online in the late 1940s, consequently reducing the demand for independent energy supplies.
Because wind turbines are based on old technology they are incredibly reliable and pretty easy to keep running for anyone who is even a reasonably good mechanic. Even making your own unit won’t require to many expensive tools.
A Jacobs wind turbine unit was installed at the South Pole by members of Richard Byrd’s Antarctic expedition in 1933. Jacobs wind turbines are still available for purchase in the US today. Wind turbines probably can be a useful alternative sources of energy for household or commercial end-users. Denmark currently sources about 20% of its national electrical energy supply from offshore wind farms.

Finding out how to make a wind turbine that will endure for a reasonable period of time is not simple but with the right guide book it can be done. Your own wind turbine can reduce the electricty bills dramatically.
