Hydropower and thermoelectric power make up 98 percent of the world’s electricity generation. These two most common forms of power are also the most water-intensive, which makes them extremely vulnerable to drought, competition over water resources and other water shortages.
Thermal power plants use fuel to create heat, which is then converted to electrical energy. These plants whether fueled by coal, natural gas, nuclear energy or even solar thermal electric energy—often require water to cool down plants’ high temperatures.
