Generating 20% of U.S. electricity from wind by 2030 is possible, alleges Pew Center on Global Climate Change

In a recent report by the Pew Center on Global Climate Change it is noted that supplying 20% of U.S. electricity from wind power by 2030 would be "challenging but not unachievable." Currently, wind and solar provide 2% of U.S. electricity production. Generating 20% from wind would, however, add 4-6% to the cost of electricity and require $3-4 billion be spent on transmission lines. To achieve this goal, the report notes that the wind turbine installation rate would have to double over that of 2008 in which 8.5 gigawatts of wind power was installed.
 
In the past such an investment would have been seen as substantial. However, in this era of hundreds of billions being spent to bailout Wall Street firms, banks, and AIG, the amount seems almost modest.
