President Obama invests in clean energy business growth and job creation through $2.3 billion of Advanced Energy Manufacturing Tax Credits. This investment positions the United States to regain leadership positions in green technologies globally. The competition for the tax credits was 
intense as the program was significantly oversubscribed with cleantech manufacturing projects. …
… “The investment tax credits, worth up to thirty percent of each planned project, will leverage private capital for a total investment of nearly $7.7 billion in high-tech manufacturing in the United States. One hundred eighty three projects in 43 states will create tens of thousands of high quality clean energy jobs and the domestic manufacturing of advanced clean energy technologies including solar, wind and efficiency and energy management technologies. ” …
Via The Whitehouse: 183 projects, 43 states, Clean Energy
Sample cleantech project:
Clean-Tech Manufacturing: “Solar Energy: PPG Industries, Inc. will produce a double anti-reflective coating for glass to make solar cells more efficient. At their Louisiana facility, PPG will produce a special tire tread component that reduces rolling resistance and improves fuel economy. Before the solar industry had begun, PPG pioneered the first low-iron glass that has been used in solar cells and on countless solar installations over the past two decades. Today, this credit will help to expand the manufacture of one of the critical components of glass solar cells, the transparent conductive oxide (TCO) coatings of the glass, without which the cells cannot function. ”
