All of this would, indeed, lead to somewhat higher electricity bills — although not nearly as high as the usual suspects claim. It’s kind of funny, actually: right-wingers love to praise the power of free markets and declare that the private sector can deal with any problem, but then turn around and insist that the private sector will just throw up its hands in despair and collapse in the face of new environmental rules. The actual lesson of history — for example, from efforts to protect the ozone layer and reduce acid rain — is that business can generally reduce emissions much more cheaply than you think, as long as regulation is flexible to allow innovative solutions.

Still, there will be some cost. Won’t this destroy jobs? Actually, no.

It’s always important to remember that what ails the U.S. economy right now isn’t lack of productive capacity, but lack of demand. The housing bust, the overhang of household debt and ill-timed cuts in public spending have created a situation in which nobody wants to spend; and because your spending is my income and my spending is your income, this leads to a depressed economy over all.

How would forcing the power industry to clean up its act worsen this situation? It wouldn’t, because neither costs nor lack of capacity are constraining the economy right now.
