Potential water shortages made worse by electricity production

Wind farm and solar panel

The biggest use of water in the US, 41%, is for power generation. Coal, natural gas, and nuclear power require large amounts of water for cooling. The same is true in other countries, many of whom are also facing water shortages. A new study says this should be a primary reason to move to wind and solar PV, because they require practically no water. In addition, another major use of electricity is to move water, especially in arid areas. In California, 19% of power was used to pump water in 2011. Thus, 60% of total California water usage is for creating energy and pumping water. Running faster and faster to stay in the same place?

During the summer of 2011, Texas experienced the worst drought in state history.

One of the main reasons residents did not experience blackouts that summer was Texas’ wind energy production, the researchers said. At least 10 percent of the state’s energy needs were provided by wind that summer, up to 18 percent on some days — making it an important alternative to nuclear, coal and natural gas.
