Wind has provided 35% of all new electric generating capacity in America since 2007

Data Source: AWEA, EIA, SEIA, SNL

Nearly 81,000 MW of new generating capacity installed between 2007 and 2010

Wind installed over 35% of all new generating capacity between 2007 and 2010, or 28,740 MW.

Turbine Productivity Up, Costs Down

Source: AWEA, U.S. Wind Industry Annual Market Report Year Ending 2010

• Turbines’ availability to make power is usually above 98%

• Taller towers and better siting let wind farms operate from the high 30% to low 40% range of capacity year-round

• A turbine with a nameplate capacity seven times larger can make 15 times more power

Iowa: Case Study of Leadership in Growing Wind Generation and Manufacturing

Iowa not only has the greatest percentage of electricity generated from wind – 3,675 MW, approaching 20% of the state’s electricity – it’s also a leading state in attracting manufacturing.

17

Significant Economic and Environmental Benefits

• Iowa’s wind industry has generated:• Support for 5,000-10,000 total direct and

indirect jobs• $16.5 million in annual property tax

payments by wind project owners

• $11 million in annual land lease payments

• Avoids over 6.2 million metric tons of carbon dioxide
