It is so basic – save money on energy and there is more to spend on other things.

Paul Krugman: Colorless Green Ideas

Now that the scientific debate over global warming is all but over, Paul Krugman looks at what we can do limit greenhouse gas emissions:

Colorless Green Ideas, by Paul Krugman, Commentary, NY Times: The factual debate about whether global warming is real is, or at least should be, over. The question now is what to do about it.

Aside from a few dead-enders on the political right, climate change skeptics seem to be making a seamless transition from denial to fatalism. In the past, they rejected the science. Now, with the scientific evidence pretty much irrefutable, they insist that it doesn’t matter because any serious attempt to curb greenhouse gas emissions is politically and economically impossible.

Behind this claim lies the assumption, … that any substantial cut in energy use would require a drastic change in the way we live. To be fair, some people in the conservation movement seem to share that assumption.

But the assumption is false. Let me tell you about … an advanced economy that has managed to combine rising living standards with a substantial decline in per capita energy consumption, and managed to keep total carbon dioxide emissions more or less flat for two decades, even as both its economy and its population grew rapidly. And it achieved all this without fundamentally changing a lifestyle centered on automobiles and single-family houses.

The name of the economy? California.

There’s nothing heroic about California’s energy policy… [T]he state has adopted … conservation measures that are … the kind of drab, colorless stuff that excites only real policy wonks. Yet the cumulative effect has been impressive…

The energy divergence between California and the rest of the United States dates from the 1970s. Both the nation and the state initially engaged in significant energy conservation after that decade’s energy crisis. But conservation in most of America soon stalled…

In California, by contrast, the state continued to push policies designed to encourage conservation, especially of electricity. And these policies worked.

People in California have always used a bit less energy … because of the mild climate. But the difference has grown much larger since the 1970s. Today, the average Californian uses about a third less total energy than the average American, uses less than 60 percent as much electricity, and … emit[s] only about 55 percent as much carbon dioxide.

How did the state do it? In some cases conservation was mandated directly, through energy efficiency standards for appliances and rules governing new construction. Also, regulated power companies were given new incentives to promote conservation…
