In order to satisfy the admonition that “California has to be a leader” — a rationale shallow even by the standards of political sloganeering — the Golden State enacted in 2006 the Global Warming Solutions Act (“AB32”), mandating a reduction in purported greenhouse gas emissions to 1990 levels by 2020. This obviously was a large prospective tax on conventional energy use. But even in the land of Hollywood fantasies and San Francisco nuttiness, people have to work to live, suggesting strongly that the employment effects of this law would not prove salutary. Not to worry, said the proponents, prominent among them Governor Arnold Schwarzenegger: California will be transformed as if by magic into a green economy, with green jobs replacing those lost with the decline in conventional energy use.
Suffice it to say that this green jobs gambit is a con job. “Clean” energy is massively expensive and unreliable even apart from its own considerable environmental problems. In short, it has to be subsidized heavily, a policy that is unsustainable beyond the near term, particularly for a state with budget deficits so huge that the governor and other public officials now engage in an annual panhandling exercise in Washington.
The basic problem is twofold. Green energy — solar, wind, etc. — is too diffuse to replace the conventional energy no longer used because of the implicit taxes imposed by greenhouse gas policies. Moreover, labor and energy are economic complements, an eternal truth that even the alchemists in Sacramento cannot change. For the period 1976-2008, during periods of energy prices and/or economic growth low and high, changes in total California energy consumption have driven changes in employment significantly, even after controlling for other central factors. Indeed, the labor intensity of California energy use — in effect, the employment supported by each increment of total energy consumption — has increased virtually every year during that period.
So, AB32, now being implemented, is a job killer in a state with an unemployment rate of 12.4 percent. Accordingly, there is an initiative on the ballot next month — Proposition 23 — that would suspend the implementation of AB32 until the state unemployment rate declines to 5.5 percent for four quarters. A new econometric study published by the Pacific Research Institute (author: yours truly) examines the employment implications of that initiative, finding that it would increase total state employment by over 500,000 in 2012, and over 1.3 million in 2020, or about 5 percent of the working-age population.
In response, the opponents of Prop. 23 have their story and are sticking with it: “AB32 is the next job bank,” and the only question is whether “all our communities and entrepreneurs [are] ready to take advantage of this opportunity.” That was the overriding question at a recent conference at the Public Utilities Commission, attended by the usual green suspects, an echo chamber at which not a single dissenting voice was to be heard.
They protest far, far, far too much. The left-wing environmentalists for decades have used apocalyptic scaremongering as a tool with which to subvert political, regulatory, and legal processes in pursuit of ever-greater confiscation of others’ property. The Alar scare. The population bomb. Power lines and childhood cancer. The supposed hazards of Frankenfood. Global famine. The Northern Spotted Owl scam. The acid rain scare. The ozone hole (actually, a one-sixteenth truth, a stout demonstration of candor by the standards of the Sierra Club). Global cooling. Global warming.
Ad infinitum. Like so many human endeavors, scaremongering seems to be afflicted with diminishing returns, a subtle implication of the enviros penchant for conjuring up a new apocalypse-of-the-century every five years or so. In the case of the global warming mother-of-all-crusades, what is fascinating is how little actually has been done, particularly in contrast to the massive efforts directed by most governments in advanced economies against real pollutants and other such problems of the commons (air, water, etc.) that are undeniable.
That highly limited actual policy response to purported global warming is not surprising. The climate models cannot predict the past or the present; why should we believe their predictions about the future? The surface temperature data are shockingly bad, and the constant revisions are always upward, suggesting the presence of something other than random error. The satellite data are limited, inconsistent with the surface data, and suggest in important respects that the models are simply wrong.
The costs of the policy responses that dominate the conference soirees, to which the anointed fly in their private jets, are massive. And the actual temperature effects of these policies a hundred years in the future would be virtually unmeasurable, even if implemented by the entire industrialized world including China and India. For reasons both obvious and subtle, neither democracies nor autocracies are inclined to accept large costs in the near term in exchange for benefits tiny, uncertain, and distant.
Except, of course, for California.
Opponents of Proposition 23 can blather all they want about “green jobs,” but the larger reality is that such employment represents less than 3 percent of state employment even under an absurdly expansive definition. More fundamentally, without a dramatic change in the state’s industrial mix — and, therefore, a hugely expensive replacement of the fixed nonresidential capital stock (over $200 billion for a replacement of “only” 10 percent) — there is no evidence that the central employment/energy relationship is changing. It will be interesting to see if the voters in this deep-blue state will choose to turn away from a regulatory juggernaut promising enormous costs and, literally, no benefits.
