In 2010, renewable energy accounted for 11.5 percent of U.S. electricity generation ($127 billion market), and is projected to grow to 15.2 percent ($263 billion) by 2015. In 2004, $300 billion was invested domestically in energy-efficient technologies and infrastructure. We distribute the electrical components that soak and harness energy from the sun and wind, and that deliver efficient lighting to homes, buildings and manufacturing facilities.
