There are a number of wind turbine on the market that are rated as "1 KW," but what does this mean when it comes to wind turbines? Well, first of all KW stands for kilowatt or one thousand watts. Watts are a measure of power or "energy output over time." But what does "1 kilowatt wind turbine" mean? Does it mean that you will get 1 kilowatt of power all the time? No!

If the wind is not blowing, you will get zero power from any turbine, no matter what the kilowatt rating. The 1 kilowatt rating is based on a specific wind speed. Usually turbines are rated at a wind velocity where the conversion efficiency is highest. For instance, a turbine converts energy inefficiently at 8 miles per hour, but will be much more efficient at say 20 miles per hour. So, the kilowatt rating of a turbine usually corresponds to a wind speed of 20 miles per hour or more. These kind of wind numbers are higher than most operators will experience at their property.

For instance, there is a turbine called the Windspire that is rated as a 1 kilowatt wind turbine. If you read the specs on the turbine it says that it guarantees 1900 kilowatt hours of energy per year with an average wind speed of 12 miles per hour.

If you do the math, the turbine produces 5.2 kilowatt hours per day in an average 12 mile per hour wind. So, the turbine is not putting out 1 kilowatt at your 12 mile per hour expected average wind velocity. At 12 miles per hour, the turbine is only putting out about .22 kilowatts, or about a fifth of its rating of 1 kilowatt.

So, what does 1 KW Turbine mean? This means the turbine will put out 1 kilowatt of power at a specific wind velocity, usually greater than 20 miles per hour.

Achieving 20% wind energy will require the number of turbine installations to increase from approximately 2000 per year in 2006 to almost 7000 per year in 2017.

Integrating 20% wind energy into the grid can be done reliably for less than 0.5 cents per kWh.Achieving 20% wind energy is not limited by the availability of raw materials.Addressing transmission challenges such as siting and cost allocation of new transmission lines to access the nation's best wind resources will be required to achieve 20% wind energy.

Offsetting the Costs of Wind Powered Electrical Technology.Although Small wind generator electrical power seems to be an unlimited resource, and, the best wind sites appear to be competitive with market electricity prices in most U.S. regions, several factors exist that make it a less appealing source of alternative energy in terms of economic cost. First off, wind is not uniformly priced resource. Its costs vary widely depending on project scale, wind speed, region, and other factors. Second, the benchmark for comparison with wind to other fuels varies regionally. Third, extra revenue is required to make a project viable, sunk costs are considerable.

To offset the factors that make wind powered electricity a less appealing source of alternative energy and promote its continued growth, wind energy in many areas receives some financial or other support to encourage development. Wind energy benefits from subsidies either to increase its attractiveness or to compensate for subsidies received by other forms of production, such as coal and nuclear, which have significant negative impacts. In the United States, wind power receives a tax credit for each Kilowatt hour produced; that was 1.9 cents per Kilowatt hour in 2006. The tax the credit has a yearly inflationary adjustment. Many American states also provide incentives, such as exemption from property tax, mandated purchases, and additional markets for "green credits." The Energy Improvement and Extension Act of 2008 contain extensions of credits for wind, including micro-turbines.

Secondary market forces also provide incentives for businesses to use .wind-generated power, even if there is a premium price for the electricity, socially responsible manufacturers pay utility companies a premium that goes to subsidize and build new wind power groundwork. Companies use wind-generated power, and in return they can claim that they are making a "green" effort.

Undoubtedly, further tax credits, subsidies and incentives will also be needed to achieve the goal of 20% Wind Energy by 2030. Today, wind power approximately accounts for about 2% of the electricity generated in the United States.

The technology of wind generated electrical power functions by creating electricity through the use of various styles of wind turbine is a very viable alternative energy. Although wind generated electrical power does have some negative impacts, this author feels that in terms of long-term cost and benefit compared with other types of energy, such as the burning of fossil fuels, using a renewable resource such as wind generated electrical power economically, environmentally, and socially is making more and more sense.

People feel the countryside should be left intact for everyone to enjoy its beauty. Where Wind Powered Electricity Can be Effectively Generated.

Places in the world where wind blows strong and often, people and businesses can harness the wind as an option to use in the generation of electricity. Globally, these places include much of North America, southern South America, Greenland, most of Europe, Northern Africa, eastern Asia, most of Australia, and anywhere there are mountains or large hills. The top 5 countries producing electrical wind power in 2007 were: Germany, United States, Spain, India and China, respectively.

Considerable wind speeds also occur across oceans and large water bodies. Since most of the world's population lives near oceans, wind farms with strong offshore and onshore breezes could produce an abundant amount of electricity. On land in the USA, the major wind corridor is the Great Plains which includes the states of North Dakota, South Dakota, Nebraska, Kansas, Oklahoma and Texas. The wind turbine also extends into the states west to the great mountains west, including eastern Montana, Wyoming, Colorado, and New Mexico. There are also considerable wind resources in eastern and southern Minnesota and the entire state of Iowa, diminishing south through Missouri and east through southern Wisconsin and northern Illinois, Indiana and Ohio. Parts of New York and the New England states also have considerable wind.

The Department of Energy (DOE) estimates that wind power could supply the US with 100% of its electricity, just from the Great Plains wind corridor or from offshore wind farms alone. According to the "Pickens Plan," a $10 billion wind farm with 2500 generators can supply enough energy for 1.3 million homes, and for $1 trillion the Great Plains wind corridor could supply 20% of America's electricity. That would be about 250,000 wind generator to supply 130 million homes.

In a report published by the U.S. Department of Energy, "20% Wind Energy by 2030: Increasing Wind Energy's Contribution to U.S. Electricity Supply," that report concluded that:

Reaching 20% wind energy will require enhanced transmission infrastructure, streamlined siting and permitting regimes, improved reliability and operability of wind systems, and increased U.S. wind manufacturing capacity.
