Wind Power ConcernsWind Power Concerns

Wind is intermittent and unpredictable

Costlier than other sources of electricity

Requires new transmission linesfrom where the wind is to where the need is

Delays up to 2 years by a lack of parts

Delays by “Not in my back yard” (even if

it’s 5 miles away)Huge first cost

The power of the wind increases in relation tothe cube of the wind speed.If the wind speed is doubled, the power outputis 8 times greater.

Wind speeds increase at greater heights.Construction that allows hub heights of 1000feet is foreseeable.

Texas becoming top site for wind power growth

T. Boone Pickens is planning to build thebiggest wind farm in the world,

.

Why build it in Texas??

Based on wind speeds at 100 feet

Energy Tax Credits

As part of the $700 Billion bailout, Congress renewedthe wind energy tax credits for 1 year, and solar for 8

Can wind power provide20% of our electricity by 2030?

Will take about $1 Trillion over the next 25 years, to installacres of wind turbines across Midwest and Great Plains,plus thousands of miles of transmission lines.

Would require cutting red tape anda “Git ‘er done” attitude.Comparable to building the Interstate Highway systemin 1950s and 60s.

As the percentage of electricity from wind and solar increases,an equal amount of “instant-on” backup generatorsare required

In Wisconsin…One company pays landowners $3,000 to $8,000a year for up to 30 years to place towers on their land.

“If you've got one turbine, that's so much. If you have three or four,it's a retirement plan."
