Texas is the undisputed wind capital of America, with over 7 gigawatts of turbine power. The only problem is that it's located in the middle of Texas and the electrical grid doesn't have the capacity to get all that extra juice to the big cities. To remove this roadblock, the state is pumping $4.93 billion into new transmission lines. If this plan sounds familiar, it's because it made news last May when it was proposed.

When completed in 2013, the bulked up electrical lines will be able to handle 18,500 megawatts of wind power. Officials say a detailed plan will be completed by August of this year.

Seven deals have already been reached with transmission firms to build the 2,400 miles of new lines, ranging from  $390 million to $1.34 billion. Each company will pay all the up-front costs, which will be made up later through higher rates for customers.

In 2006, Texas overtook California in wind energy capacity and has since built a two-fold lead over the Golden State. In fact, Iowa is now the 2nd place challenger with 2,790 megawatts.
