Photos: Top fifteen inventions and innovations of the National Renewable Energy Lab

In print, we take an in-depth look at NREL's important role in solar energy and other industries over the past three decades. Here, we count down the top fifteen inventions and innovations NREL leaders tout as the lab's key accomplishments.
