Coal-fired power plants produce CO2 daily as waste products, nuclear power plants use fuel rods annually and solar energy uses nothing. The costs for coal-fired

Coal-fired power plants produce CO2 daily as waste products, nuclear power plants use fuel rods annually and solar energy uses nothing. The costs for coal-fired and nuclear power plants are after 50 years, for solar cells probably after 15 years. So the environmental impact is expected to be 50 years, although Chernobyl cannot be recycled forever.
