Why wind over solar ?

The cost of utility-scale wind power has come down dramatically in the last two decades due to technological and design advancements in turbine production and installation. In the early 1980s, wind power cost about 30 cents per kWh. In 2006, wind power costs as little as 3 to 5 cents per kWh where wind is especially abundant. The higher the wind speed over time in a given turbine area, the lower the cost of the electricity that turbine produces. On average, the cost of wind power is about 4 to 10 cents per kWh in the United States.

Energy Costs Comparison

Implementing a small wind turbine system for your own needs is one way to guarantee that the energy you use is clean and renewable.

Advantages of wind cost (information from US Department of enegry)

Wind energy is fueled by the wind, so it's a clean fuel source. Wind energy doesn't pollute the air like power plants that rely on combustion of fossil fuels, such as coal or natural gas. Wind turbines don't produce atmospheric emissions that cause acid rain or greenhouse gasses.

Wind energy is a domestic source of energy, produced in the United States. The nation's wind supply is abundant.

Wind energy relies on the renewable power of the wind, which can't be used up. Wind is actually a form of solar energy; winds are caused by the heating of the atmosphere by the sun, the rotation of the earth, and the earth's surface irregularities.

Wind energy is one of the lowest-priced renewable energy technologies available today, costing between 4 and 6 cents per kilowatt-hour, depending upon the wind resource and project financing of the particular project.

Wind turbines can be built on farms or ranches, thus benefiting the economy in rural areas, where most of the best wind sites are found. Farmers and ranchers can continue to work the land because the wind turbines use only a fraction of the land. Wind power plant owners make rent payments to the farmer or rancher for the use of the land.
