The National Renewable Energy Laboratory opened the Solar Energy Research Institute in Colorado 35 years ago.
NREL's 327-acre main campus got an infrastructure boost in 2006 and 2007 when projects in the pipeline were accelerated. On the right, beyond the solar panels, is the Research Support Facility, recently tagged as the top net-zero energy building in the world.
