Why are water and electricity often though about separately?

"Electricity production from fossil fuels and nuclear energy requires 190,000 million gallons of water per day, accounting for 39% of all freshwater withdrawals in the nation, with 71% of that going to fossil-fuel electricity generation alone.

Coal, the most abundant fossil fuel, currently accounts for 52% of U.S. electricity generation, and each kWh generated from coal requires 3.3 gallons of water. That means U.S. citizens may indirectly depend on as much water turning on the lights and running appliances as they directly use taking showers and watering lawns. According to the Bush administration's 2001 National Energy Policy, our growing population and economy will require 393,000 MW of new generating capacity (or 1,300 to 1,900 new power plants—more than one built each week) by the year 2020, putting further strain on the nation's water resources."

"Proposed restrictions on the use of water for power generation to protect fish and other aquatic organisms could result in increased costs of electricity or potential energy shortages.

Rising costs associated with electricity.

Because the energy required for treatment and delivery of water accounts for as much as 80% of its cost, an insufficient supply of affordable energy will have a negative impact on the price and availability of water.

The interdependency between the water and carbon cycles could lead to shifts in water distribution that are difficult to predict. That is, increases in electricity production – and use – may lead to higher levels of atmospheric carbon, which can impact the availability of water to electricity producers in certain regions.

In summary, the link between clean, affordable energy and clean, affordable water is crystal clear. There cannot be one without the other."
