Not consuming energy is better than buying or producing it—even when that energy is generated by clean, renewable solar. That’s the message the U.S. Department of Energy Solar Decathlon 2015 is sending to decathletes through the Energy Balance Contest, which measures the energy each team house produces and consumes over the course of the competition.

Since the U.S. Department of Energy Solar Decathlon 2009, a temporary, ground-laid electrical grid (or “microgrid”) has connected Solar Decathlon houses with one another and the local utility. The village microgrid allows excess power generated by the houses’ solar electric systems to be sent back to the larger city utility grid and its customers. The microgrid also enables the competition houses to draw energy from the utility when consumption exceeds production.

I am proud to be an American—and prouder yet to be an employee of the U.S. Department of Energy. We brought an inspiring and beneficial competition to the People’s Republic of China! By the end of the event, a quarter-million people will visit the competition houses displayed at Solar Decathlon China. The event has made a real impression on the government and people of Datong. I hope it leads to positive change.

How do you identify the measured contest captain on each U.S. Department of Energy Solar Decathlon team? Listen for words such as datalogger, monitored performance subcontest, and database-driven scoring application.
