There is much more to renewable energy than saving fossil fuels and improving carbon emissions. Because water and energy are closely connected, technologies like wind and solar power, digester-gas-to-energy, and geothermal heating and cooling also help make optimal use of increasingly stressed water resources.
Technologies like wind, solar and geothermal help reduce demand on increasingly stressed water resources while also conserving fuels. At the same time, renewables can replace some of the fossil-fuel energy needed to pump, treat and heat water.
