Wind Power: Frequently Asked Questions
Why wind power?
It saves our natural resources
It creates no air pollution
It doesn't create any other bad by-products like nuclear waste
It’s a great source of supplemental income for farmers and ranchers
It doesn't cost very much more now, and creates a clean, non-confrontational energy future for the planet.

Some wind power locations are appropriate but the available watts per square foot of wind turbine area are such that if it were used extensively the result would be an endless fight over urban aesthetics, noise and bird kills. Some locations work well with wind power but it is not a sustainable option that all can implement without deleteriously impacting our neighbors and community.

Wind power produces no pollution or emissions of any kind, and employs technology that’s been proven worldwide. Unlike traditional energy forms, such as coal or oil, wind farms generate clean, renewable energy without high costs, environmental risks or health risks. Wind power is also a local, sustainable energy alternative, increasing North America’s energy independence and helping to stabilize electricity costs.

What is the power factor in the wind?
Every time the wind doubles, the power factor increases 8 times (8:1 ratio). For example, if you have a 10 KW wind machine, and the wind blows at 12 MPH for 24 hours, you would get 49.9 KW in that time. However, if the wind blows at 24 MPH for only 12 hours, you would get 419 KW in that time!

What is wind power?
Wind energy is a form of solar energy. Sunlight falling on oceans and continents causes air to warm and rise. Cooler air rushes into the space left by the risen air, which in turn generates surface winds. Wind systems capture the energy in wind using large blades mounted on tall towers called turbines. The wind turns the blades and the blades rotate a generator, which produces electricity.

Wind power is converting wind into a usable energy, electricity, using windmills or turbines.
Source: www.freedomrenewable.com
Wind energy is a converted form of solar energy. The sun heats different parts of the earth and its surfaces at different rates causing the atmosphere to warm differently. As the hot air rises cooler air is drawn down to replace it. This process creates wind. The motion of the wind creates kinetic energy that can be converted into other energy such as electricity using wind turbines.

Wind power generally refers to the electricity that is generated by wind turbine through the natural movement of air (i.e. wind). The first automatically operated wind turbine for electricity generation is said to have been developed by an American named Charles F. Bush in 1887. Later the development of wind power received impetus in Denmark where some 120 local utilities in Denmark had a wind turbine by 1918. ...

Wind power is now the fastest-growing renewable energy source in the world and it is 100 percent pollution free. The wind power we use is supplied with New Wind Energy, a product of Community Energy, Inc., and comes from modern wind turbines mounted on tall towers on farmland in upstate New York and Pennsylvania.

What are the advantages of wind power?
Wind power has the potential to generate clean, utility-quality power 24 hours per day, 365 days of the year, night and day. The solar industry estimates only 5.5 hours of production of solar energy per day in some central California latitudes. Marquiss Wind Power’s patented turbines have a quicker payback period, or return on investment (ROI), than any renewable energy source on the market.

How is wind power generated?
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 to power homes, businesses, and schools.

How is wind power sold ?
Our wind power is sold in the form of Renewable Energy Credits (RECs). Each REC is equal to 1,000 kilowatt-hours (kWh) or one megawatt-hour of energy. 2.

Is wind power reliable?
Yes. The wind turbines that you see today are the result of decades of research and development. Thanks to these efforts, modern turbines are highly efficient. The science of wind turbine placement has advanced a great deal. The output of a wind farm can be predicted accurately well before a shovel hits the ground.

How will wind power be produced?
Wind power will be produced using utility scale wind turbines. The number of turbines built will be determined by the number of customers who choose to subscribe for the service. The higher the level of Wellspring subscriptions the larger the new wind farm. Currently, wind for the Wellspring program comes from the Chandler Hills Wind Farm (nine 660-KW wind turbines with a combined nameplate capacity of nearly 6 MW) and 6-MW wind farm located near Dodge Center, Minnesota. ...

How wind power is calculated?
Wind power is measured in W/m² (Watt per square meter) of swept area and is equal to ½ ρ v ³ (where ρ is air density in kg/m³ and v is wind speed in m/s).

Why is wind power important?
Today, people all over the world are destroying its resources. The main source of energy today comes from valuable, nonrenewable fossil fuels that pollute the environment. Sooner or later we will need a type of energy that is safer, less polluting, and renewable. However, wind power is a renewable source of energy that is clean and safe.

What if the wind slows or stops? Is wind power reliable?
Wind power is reliable. Electricity from a wind power facility is connected to a fully integrated, diversified utility transmission system. When the wind project is not generating during low wind, similar to a hydro plant when there are low flow conditions, power is compensated by other generators in the system. Wind project’s reliability is measured by their availability to run, which often is recorded in the 95-98% of the time range.

How does wind variability affect wind power reliability?
A wind turbine's production is usually expressed as an annual average, masking its highly variable output. But because production falls off dramatically as the wind speed drops (by a factor of eight for every halving of the wind speed), most of the time the wind turbine is producing well below its average rate. The average rate of output or more is seen only about a third of the time.

How does wind power compare to photovoltaic power plants?
Many owners of a photovoltaic plant a have small wind turbine at the same time. This makes sense because the photovoltaic plant only inducts the produced electricity into the grid. A small wind turbine is urgently used for own energy consumption. Even if the side is not optimal the energy output of a wind turbine is much higher and through that there are shorter payback periods also without subsidy.

How much back-up power is needed for wind power?
According to Eon Netz, one of the four grid managers in Germany, with 7,050 MW of wind power capacity installed in its area at the end of 2004, the amount of back-up required was over 80%, which was the maximum output observed from all of their wind power facilities together. That is, for every 10 MW of wind power added to the system in this case, at least 8 MW of back-up power must also be dedicated.

No, wind is a very competitive source of energy generation. A study published in Wind Power Monthly (6) about the costs of generation around the world found that 'Wind is already competing with coal, it is cheaper than nuclear and cheaper to exploit at large scale than any of the other renewable energy sources. In some regions it can be competitive with gas-fired generation today. ' The generation costs of onshore wind power in the UK are around 3.2p per unit, with offshore at around 5.5p per unit. ...

Is wind power subsidized?
Historically, the energy industry has been subsidized as a means of ensuring that the country has adequate and reliable supplies of energy. The National Commission on Energy Policy found a low-end estimate for federal energy subsidies in 2003 to be $37 billion to $64 billion. Total wind energy subsidy payments in that same year are estimated at $155 million - well under one percent of the federal energy subsidy total. ...

What are the benefits of wind power?
Wind power is clean, abundant and reliable. It is a renewable source of energy, it does not produce any greenhouse gas emissions, and because wind turbines use less than 5% of the land where they are sited, they minimize habitat destruction, help preserve open space, and allow for multiple uses of the land such as agricultural farming.
