To their left is a new parking garage, one designed to receive sunlight and dramatically minimize energy use.
That parking garage is part of what NREL got with the $156.1 million it collected through the American Recovery and Reinvestment Act. The rest of the stimulus funds went to support the expansion of a new "Research Support Facility," a buildout and upgrade of an "Integrated Biorefinery Research Facility," the construction of new technology at NREL's wind center near Boulder...and construction of the new access road.

The total cost of that new road was $6.31 million, which includes all infrastructure costs as well as the new roundabout on South Golden Road.
But this latest round is just a small piece of the facility's financial history. "Lots of the nation's investments actually come flowing through here...and that makes NREL the central point...for all of these technologies," explains Baker, the DOE's director of laboratory operations in Golden, as he shows off the new Research Support Facility.
The RSF, as the building is known, is a groundbreaking structure that the NREL team calls a "net zero energy building": It uses 50 percent less energy than current commercial codes with a wide range of strategies, including solar collectors, day lighting in office spaces, and under-floor ventilation. In the cafeteria, the countertops are made of recycled sunflower seeds; large repurposed natural-gas pipes are integrated into its structure. The RSF shows just what is possible using the best energy-conservation practices, many of which were developed on this very campus.
Since the lab's founding in 1977, Baker estimates, NREL has taken in roughly eight to nine billion dollars (in today's dollars). That's a lot of money, but you need to consider it in the context of energy spending, he suggests: Nine percent of the nation's gross domestic product, or $1.4 trillion a year, is associated with energy. Compared to that figure, the investment in NREL doesn't seem so huge. About 80 percent of NREL's direct funding comes from the DOE's Office of Energy Efficiency and Renewable Energy, and the other 20 percent comes from other DOE sources and outside sources.
What has the country gotten for its money?
The basic progress that NREL has made in renewable technology is the most direct and visible indication that the nation and the world is getting an enormous return on this investment, Baker says. From NREL's perspective, the lab's renewable-energy discoveries have dramatically shaped our transportation alternatives and directly provided new options to power homes and businesses.
The cost of wind energy, for example, has declined from 40 cents per kilowatt-hour when the lab was founded to between 6 and 9 cents today, helping wind energy become the fastest-growing source of new electricity in the nation. And the cost of electricity from photovoltaic panels — which convert sunlight directly into electricity — has dropped from several dollars per kilowatt-hour to 18 to 23 cents per kilowatt-hour.
None of these advancements would have happened at this speed — if they had happened at all — if not for the DOE's investments in the laboratory, Baker says. "Look at the size of the industry today," he continues. "When you see billions and billions of dollars of the renewable energy in photovoltaics and wind, then you come back and say, 'Well, where did all that start?' It started here at NREL. It made all those industries possible."
According to NREL lab director Arvizu, in 1977 the cost of gasoline was 62 cents and the cost of a photovoltaic panel was $100 a watt. Since then, there has been a six-fold increase in gas prices and a 25-fold decrease in the cost of photovoltaic panels. This kind of innovation was made possible by NREL, Arvizu says.
But while NREL has undoubtedly played a huge role in some of the fundamental innovations that have brought solar, wind and other technologies to where they are today, where else might they have gone over the past three decades? Ken Zweibel worked at NREL from 1979 to 2006 and was a director of the thin-film photovoltaics partnership there. "My question is how effective these contributions have been in the sense that [most of] these companies themselves haven't necessarily stuck around and really made an impact," Zweibel says.
If you try measuring the success of the lab by the success of private companies that have attempted to commercialize these technologies, the story of NREL becomes a lot more complicated. In fact, just as NREL was preparing to celebrate its 35th anniversary this summer, Colorado got disappointing news about two of the state's major solar companies. One was going to put on hold a large manufacturing plant it had planned for Aurora; the other would be filing for bankruptcy and shutting its doors for good.

On a tour of NREL in 2005, Brian Murphy was impressed by the research. "I was just really awestruck by all the neat things the scientists were doing in the lab," he remembers.
Murphy had previously worked in applied films technology, which he saw as a perfect foundation for getting into the solar-panel market. It was clear that NREL had the expertise he needed to develop this technology. But it was also clear to Murphy that the lab could have a greater impact if it partnered much more closely with the private sector. "'Why isn't this stuff getting out to the world so people can take advantage of it? So society can benefit from all this unique technology and...really leading-edge stuff?'" he recalls thinking. "It was very clear that the scientists were very proud and excited with what they were doing. It was also clear that there didn't seem to be a great link to industry." It would be a win-win for Murphy and NREL if they joined together and worked on commercializing solar panels.
