In 2007, the U.S. solar energy industry saw a glimpse of a gigawatt future. There was signi?cant growth in the commercial and residential PV markets and a new utility-scale segment for PV emerged with the fastest growth of all segments representing over 15 percent of the annual U.S. installed PV capacity. The ?rst concentrating solar power plant was built in more than 15 years with dozens more utility-scale projects in the pipeline. The expansion of the solar water heating market continued. Thousands of U.S. jobs were created and billions of dollars were invested. And, the industry strengthened its presence in Washington and our united coalition support across the country.
