Lots of Sun. Lots of Rooftops. But Not Lots of Energy. Why Not?

Commercial real estate agents and planners like to use the phrase "rooftops" when they talk about growth patterns.

When a shopping center is proposed, it's usually because the new "rooftops" in the area warrant it. New schools are considered when "rooftops" are projected to reach critical mass. But how often is the phrase "rooftops" linked with another phrase - "solar."

Not very often. By some estimates, less than one-tenth of a percent of the electricity in the United States comes from rooftop solar and solar power plants, according to this report. The percentage should be much higher, especially in the San Joaquin Valley, where temperatures reach triple digits and residential power bills have been known to contain a comma.
