California, whose population is 12 million higher than ours,
uses only 60 percent of the energy we do
This is sometimes called the Rosenfeld Effect for the long-time member of the California Energy Commission who pioneered energy efficiency standards, Dr. Arthur Rosenfeld.
Here's a great interview with Rosenfeld upon his retirement from the commission, "Art Rosenfeld, the 'godfather' of energy efficiency",

There's also a Wikipedia article for Rosenfeld Effect,

There are disputes about how effective California's strict energy efficiency standards have been. But the Mercury News article is a great read simply because Rosenfeld seemed to have been a great scientist who left lasting impressions with all the people he worked with, not to mention on our laws and standards. He passed away at the beginning of this year.
