Before the economic collapse, before President Obama's election, before cries for action to help ailing businesses, construction workers started building Barton Chapel wind farm in Texas. Turbines started turning at the farm in January 2009 as Congress debated the stimulus bill. A few weeks later that legislation became law and launched a grant program aimed at spurring green energy growth. The new program paid developer Iberdrola Renewables Inc. $72.6 million for building Barton Chapel Wind, even though the farm was finished when the stimulus bill became law. Iberdrola was not alone in collecting stimulus funding for a development under way or completed when the program took effect. Of the 50 highest dollar grants awarded, 64 percent -- worth a combined $2.7 billion -- went to projects that began construction before the stimulus measures started, a Greenwire analysis of the program found.
