California’s Boneheaded Solar Remedy for Climate Change

Good intentions can make for awful policies.

In the world of government policy, two chief dangers always loom. The first is people with bad intentions using every available means to achieve their malignant goals. The second, more common but no less destructive, is people with the purest of hearts and the most boneheaded of methods.

For an example of the latter, look west, where the California Energy Commission just decreed that starting in 2020, new homes must be equipped with solar panels. Commissioner Andrew McAllister boasted that the rule “will propel the state even further down the road to a low emissions future.”

He has the right idea. With environmental vandals in charge of the federal government, the state’s leaders are justifiably motivated to do what they can to combat climate change.

“We don’t want to do nothing and just sit there and let the climate get worse,” Gov. Jerry Brown said last year. California is at particular risk from global warming, which will inundate low-lying areas of its 840-mile coastline with rising salt water while fostering more droughts and wildfires inland.

Its utilities are already on track to get half their energy from solar and other renewable sources as soon as 2020. The state is also fighting the Environmental Protection Agency’s plan to gut controls on vehicle tailpipe emissions. The energy commission says the solar panels and other requirements will cut a typical new home’s energy consumption by 53 percent—”equivalent to taking 115,000 fossil fuel cars off the road.”

But there are three major flaws in this approach. The first is that it’s a highly inefficient way to expand solar energy. University of California, Berkeley economist Severin Borenstein told the commission that he and the vast majority of energy economists “believe that residential rooftop solar is a much more expensive way to move towards renewable energy than larger solar and wind installations.”

No kidding. The National Renewable Energy Laboratory figures that on a kilowatt-hour basis, electricity from home solar panels costs 2 1/2 times more than electricity from large solar facilities operated by utilities.

The California approach brings to mind Mao Zedong’s call in the 1950s for Chinese peasants to build steel furnaces in their backyards. Many vital tasks are done best on a huge scale, and generating electricity is one of them.

Another drawback is that it will aggravate the state’s most notorious problem—astronomical housing costs. The median home price is now $524,000, in large part because of regulations that make every attempt to put up new housing only slightly less challenging than the Normandy invasion. California has fewer residential units per person than 48 other states. It’s a major reason more people are leaving the state than coming.

The new mandate will be another burden on new home construction and purchase because it is expected to add $10,000 or more to the cost.
