4. Pros and Cons of Wind power

7. Wind speed vs. Number of hours of wind Related to variability is the short-term (hourly or daily) predictability of wind plant output. Like other electricity sources, wind energy must be "scheduled".

9. Land Use To reduce losses caused by interference between turbines, a wind farm requires roughly 0.1 square kilometres of unobstructed land per megawatt of nameplate capacity. A 200 MW wind farm might extend over an area of approximately 20 square kilometres. Clearing of wooded areas is often unnecessary. Farmers commonly lease land to companies building wind farms. In the U.S., farmers may receive annual lease payments of two thousand to five thousand dollars per turbine. The land can still be used for farming and cattle grazing. Less than 1% of the land would be used for foundations and access roads, the other 99% could still be used for farming. Turbines can be sited on unused land in techniques such as center pivot irrigation. The clearing of trees around tower bases may be necessary for installation sites on mountain ridges, such as in the northeastern U.S.
