Oil and Water Truly DonБЂ™t Mix Everyone knows that it takes water to get food. Less obvious is how much energy it takes to get water (for pumping, moving, purifying, and so on). And hardly anyone grasps how much water is needed to get energy. But like hopeless lovers, water and energy are inextricably intertwined. Pressure on water resources, therefore, is intimately linked to pressures on coal, oil, and natural gas resources. Except for wind and certain forms of solar power, even renewable energy sources demand a lot of water. Power plantsБЂ”regardless of whether they run on coal, natural gas, uranium, biomass, garbage, or whateverБЂ”use water in at least two important ways: to make steam to turn a turbine and thus generate electricity; and to get rid of excess heat. The single greatest demand for water in the energy sector today is for the cooling of power plants. Over half of all water withdrawals in the United States alone, slightly more than for irrigating crops, are used for this purpose. ThatБЂ™s a half-billion acre-feet of water per year (enough to flood the entire country ankle-deep in water) to cool off our power plants ...»
