Not since President Jimmy Carter had solar panels installed at the White House has there been as much hype for renewable energy sources as there is now. Congress once again is pushing for passage of legislation mandating a "renewable portfolio." South Carolina is wisely letting the free market determine whether renewables will catch on. But 25 states have adopted renewable energy requirements, committing nearly half of our country's population to obtaining as much as 25 percent of their electricity from solar, wind and other "green" sources by 2020. Increasing our use of renewable energy is a worthwhile goal. But if we allow the heavy hand of government to mandate its use, we're setting solar and wind energy up to fail. ...Wind power has appeal not because it's clean, but because tax breaks and subsidies for wind are now so valuable for wind-farm owners.

Not since President Jimmy Carter had solar panels installed at the White House has there been as much hype for renewable energy sources as we are witnessing now.

Tax breaks and subsidies for wind are now so large that their value to wind farm owners - not any possible environmental benefits - is the primary motivation for building a wind farm. Over the past decade, large-scale wind farms have been built in Texas, California, Kansas, Wyoming and other states. But at best, the wind blows only 40 percent of the time. Wind is so unpredictable that electricity shortages have hobbled businesses and industries in both Texas and California, the two states with the most wind energy capacity, mainly because the wind stopped blowing and wind turbines were operating at only 5 percent of capacity.
