Winston Churchill famously quipped, “However beautiful the strategy, you should occasionally look at the results.” What could be more beautiful, never mind seductive, than the strategy to promote renewable energies and a “green economy,” heralded as cure-alls for America's greatest challenges, most particularly economic stagnation?

But a funny thing happened on the way to green utopia. High-paying, clean-tech jobs were a cornerstone of the 2009 stimulus bill, which appropriated $80 billion to promote the “green economy.” Yet, instead of putting us on the green-brick road to recovery, we've learned that subsidizing industry merely results in red — lost jobs, squandered taxpayer resources, scandalous bankruptcies and diminished prosperity. “Green” proponents whose policies produced these shameful outcomes should be red-faced and prepared to Think Again.

With nearly one in six Americans living in poverty — the largest total since tracking began in 1959 (according to newly released Census data), and persistently high unemployment, Americans desperately want to believe the green-jobs predictions of advocates like Van Jones, who wrote “The Green Collar Economy: How One Solution Can Fix Our Two Biggest Problems.”

Yet the reality is that these lofty job creation projections are wrong, as detailed in last month's New York Times story “Number of Green Jobs Fails to Live Up to Promises.” The Times concluded, ”such numbers are a pipe dream” because, as they've previously reported, wind power costs 50 percent more than conventional power, and solar-generated electricity costs up to three times more than wind power. Shifting resources toward less-efficient purposes inevitably results in less prosperity — fewer jobs at lower pay.

Furthermore, in order to compete, renewable energy sources require costly government subsidies, price floors or purchase mandates. Consequently, green policies actually increase energy prices, undermine the economy, destroy jobs and hurt consumers, especially the poorest whose family budgets are consumed by escalating costs for everything. Exacerbating things further, energy prices increase when potential suppliers and energy entrepreneurs redirect scarce capital away from government-manipulated markets.

For these reasons, renewable energies produce only 3 percent of U.S. electricity and remain a fledgling global industry, despite having enjoyed enormous government support in the U.S., Europe and China. Given the industry's small size and inherent unviability, allowing China to subsidize production to remain the lower-cost manufacturer is logical and prudent.

The question remains: Why didn't we examine the troubling European experience with the green-economy strategy before launching our own? After a decade of experimentation and faced with job losses, higher energy prices, economic stagnation and corruption, European governments have cut their green funding. Kenneth Green of the American Enterprise Institute summarizes the findings of research studies conducted across Europe: For every green job created, green programs destroyed 2.2 jobs in Spain and 3.7 jobs in the U.K., while the capital needed for one green job in Italy could create almost five jobs in the general economy. Wind and solar power have raised energy prices by 7.5 percent in Germany, and caused Denmark to have the highest electricity prices in Europe.

Perhaps U.S. policymakers ignored the European experience because they wanted the power and resources to pick winners and losers in the energy sector and to dispense favors to political patrons. But when government presses its massive thumb on the market scale, businesses have huge incentives to win favors through lobbying and campaign contributions. This is not only economically damaging, it's the definition of crony capitalism, the destructive consequences of which were exposed last month by the bankruptcies of three politically connected U.S. solar companies — Solyndra of California, Evergreen Solar of Massachusetts and SpectraWatt of New York. All were showcases for the green-jobs strategy, so their demise has eliminated thousands of these jobs.

Solyndra, whose major shareholder is a significant political donor, was the first clean-tech company to receive a loan-guarantee following passage of the stimulus bill, even though the Energy Department credit committee had already unanimously rejected the loan in early January 2009. ABC News reported Tuesday that Solyndra is under criminal investigation because newly uncovered emails show that they might have bypassed normal vetting procedures in obtaining their loan approval, despite being deemed a high risk.

Even if corruption wasn't a factor, the Solyndra debacle demonstrates the ineptitude of government officials when speculating with other people's money — they pale in comparison to more experienced investors who risk their own money.

So after examining the results, it's that clear green policies haven't made us happier, healthier and richer. Instead, they've lowered living standards globally and weakened the technological progress that market forces usually deliver, distracting us from finding optimal solutions to the economic and environmental challenges we face.

Like the proverbial vampire who fears daylight, optimal solutions are the last thing “green energy” proponents want to see. Given the economic bloodletting, American policymakers must Think Again and drive a stake through the vampire's green heart.
