Renewable Energy: Not Cheap, Not Green?

Abstract

A multi-billion-dollar government crusade to promote renewable energy for electricity generation, now in its third decade, has resulted in major economic costs and unintended environmental consequences. Even improved new generation renewable capacity is, on average, twice as expensive as new capacity from the most economical fossil-fuel alternative and triple the cost of surplus electricity. The uncompetitiveness of renewable generation explains the emphasis pro-renewable energy lobbyists on both the state and federal levels put on quota requirements, as well as continued or expanded subsidies. Yet every major renewable energy source has drawn criticism from leading environmental groups: hydro for river habitat destruction, wind for avian mortality, solar for desert overdevelopment, biomass for air emissions, and geothermal for depletion and toxic discharges.
