The high-powered US investor Warren Buffett has been all over wind energy development in Iowa [cleantechnica.com], and his MidAmerican Energy company has just one-upped itself with a new plan called Wind XI. If approved, the new $3.6 billion wind development initiative would enable MidAmerican to provide its Iowa customers with a grid mix that includes 85 percent wind energy, up from an already impressive current level of 47 percent.

The new turbines will generate up to 2,000 megawatts and put Iowa even farther ahead of the other 49 US states when it comes to wind energy generation statewide. Iowa is already the only state in the US to pass the 30 percent threshold, and the new turbines will put it over 40 percent.To gild the clean power lily, the project will not require state subsidies, and MidAmerican has pledged that its customers’ electricity rates will not increase as a result of the new investment.
Opponents argue the new project would chop air particles into bits and cannot be allowed.
