Economic Harm from the Wrong Energy Policies

May 28, 2003

Versions of the energy bill currently before Congress include some economically harmful proposals, including greenhouse gas emissions limits, renewable energy mandates and increased fuel economy standards. If enacted, these regulations would retard economic growth and reduce consumer choice, says NCPA Senior Fellow H. Sterling Burnett.

For example, a renewable energy portfolio mandate would require each energy provider to ensure that 10 or 20 percent of its delivered energy comes from a renewable energy source. Proponents argue that such a mandate would improve air quality, and reduce both the threat of global warming and U.S. dependence on foreign energy supplies.

However, neither wind nor solar power is economically competitive with fossil fuel. The costs for both solar power and wind power have fallen considerably, but even with generous subsidies [See Figure I.]:

  • New solar-power capacity is triple the cost of new natural gas-generated electricity and quadruple the cost of power bought on the open (spot) market.
  • New wind power capacity costs 50 to 100 percent more than new gas-generated electricity and spot-market power

Due to the intermittency of their power source, both types of plants must be backed up by fossil fuel power plants -- an expensive redundancy.

With even modest economic growth during the next 20 years, U.S. electricity demand could increase by more than 45 percent. Thus, requiring each utility's generating portfolio to include intermittent, high-cost wind and solar energy would condemn the nation to energy shortages and stagnant economic growth.

Among other proposals is increasing the Corporate Average Fuel Economy (CAFE) standard. However, raising CAFE standards to 40 mpg would reduce greenhouse gas emissions by less than half of 1 percent -- a negligible amount.
