When will solar and wind electric systems replace coal and nuclear power plants?
The US electrical power infrastructure has been built on coal and natural gas. It will take time to replace this infrastructure with renewable energy resources. As public demand for clean energy increases, and society acknowledges that our supply of natural gas is dwindling, the existing industry will be forced to shift to renewable energy sources. Fossil-based energy pollutes the environment, and nuclear energy creates hazardous waste. If we stop to consider the environmental and health costs of fossil-fuel and nuclear energy, then solar and wind energy already makes sense today.
