Despite expensive and extensive green-job policies, a surprisingly low number of jobs were created. And about two-thirds of those "green" jobs were just to set up the energy source, in construction, fabrication, installation, marketing and administration. Only 10 percent of the green jobs created were permanent jobs actually operating and maintaining the renewable sources of energy.

Each wind industry job created in Spain required a subsidy of about $1.4 million. Overall, the average subsidy cost for each green job was about $800,000 (571,138 euros). And to create about 50,000 green jobs, Spain lost 110,000 jobs elsewhere in the economy, principally in metallurgy, nonmetallic mining and food processing and in the beverage and tobacco industries.

Each green megawatt brought on line destroyed 5.28 jobs elsewhere in the economy (8.99 by photovoltaics, 4.27 by wind energy and 5.05 by mini-hydropower). The total higher energy cost -- the higher cost of renewable energy over the market price of carbon-based energy -- between 2000 and 2008 was about $10 billion. Moreover, the report concluded, "These costs do not appear to be unique to Spain's approach but instead are largely inherent in schemes to promote renewable energy sources."

The high cost of green energy predictably drove energy-intensive Spanish companies and industries out of Spain to countries with cheaper carbon-based energy, while the cost to Spanish taxpayers of renewable-energy subsidies was "enormous … 4.35 percent of all (value-added taxes) collected, 3.45 percent of the household income tax, or 5.6 percent of the corporate income tax."

There is much more in the report, which at about 50 pages in length would make useful reading for our elected representatives. Those who are worried about global warming may, after studying this report, still want to subsidize renewable-energy production. But it will be hard for such people to honestly continue to believe that they can think they are addressing global warming while creating millions of net new jobs.
