Nuclear power, strike 3

Nuclear power demands huge quantities of water (43,000 gallons per megawatt hour), making it an unlikely candidate for our water-constrained future.

The race towards carbon neutrality has precipitated a sort of selective blindness when it comes to environmental impacts other than CO2 —impacts like air and water toxicity, habitat encroachment, and freshwater consumption — all of which get sidelined in the debate over our future energy supply. Water, it turns out, may be a far greater problem than CO2 and a problem that may hit us more quickly.
 
Even removing projections on climate-induced summer droughts, most of the U.S. is expected to have moderate to severe water shortages simply due to increased population (and the food and energy demands that go with it) according to a recent report by the Sandia National Laboratory (PDF):
 
 
So knowing that, why would we invest in a source of energy that requires enormous quantities of fresh water to produce? Nuclear uses on average 43,000 gallons per megawtt of electricity, significantly more than coal which uses 36,000 gallons (a total of about 60 trillion gallons last year). By comparison, natural gas use 14,000 gallons per megawatt hour with solar (even water-cooled CSP) and wind using less than 1,000 gallons per megawatt hour. 
 
Strike 3 for Nuclear ... where's all that water going to come from?

75% of the earth surface is covered with water, so no problem of water supply. And the water that boils off the nuclear plants is returned to the surface as rain, contributing to the fresh water supply of the planet. Clearly the guy that wrote this article an anti-human-development, extremist tree hugger, blinded to the facts moron.

Nuclear Sites also get their cooling water from man-made lakes constructed by the utility adjacent to the facility. I happen to know of a few sites where the fishing is great because the lakes are stocked by the plant owners - and the fish are not contaminated by mercury like the fish from the Great Lakes, nor are they radioactive.

Thermal and evaporative cycles dont "consume" water. Mother nature recycles and cleanses it for you! http://en.wikipedia.org/wiki/Water_cycle

If you don't like nuclear due to water consumption, then you really don't like solar thermal. Solar thermal uses even more water (the fraction evaporated), and must be sited in locations where clouds are infrequent and thus water is scarce. We're looking forward to your next article on the topic of solar thermal power.

Yes, nuclear power plants need a lot of water for cooling. But the water is not used up. Usually either a river or a lake is used for cooling the secondary side water, thereby raising the water temperature of the river or lake a few degrees. Oceans also make good heat sinks. But again, very little water is actually used up.

It is stories like this that mislead Americans - and for what purpose? There has been a 40 year effort to socialize America and reduce our freedoms. Being.... More
