We do not just need water to survive, it needs to be freshwater.
Water Use in the United States
Globally, nearly 2.1 billion people lack access to safe drinking water in their homes and about 4.4 billion lack access to proper sanitation, putting them at risk of disease.

U.S. Geological Survey reports: Thermoelectric-power withdrawals accounted for 45 percent of total water use in the United States. (https://water.usgs.gov/edu/wupt.html)
THAT IS NEARLY HALF OF ALL OUR AVAILABLE FRESHWATER, THAT WE CAN GET FROM SOLAR OR WIND POWER
Unsafe Drinking Water
Contaminated water is a leading cause of death for children in developing countries.
Bad water kills 4,000 children a day! These deaths have come down significantly over the last decade, from 1.2 million per year in 2000 to about 760,000 a year in 2011. (www.unicef.org)
Over 300 million people live in the United States.
If each person decreases their shower by two minutes each time, we could be saving TRILLIONS of gallons of water each year.
According to the United States Environmental Protection Agency:
1 kWh of thermoelectric generation =
25 Gallons of Water
THUS,
40watts=1gallon of water
​
Different light bulbs burn different amounts of water, for example:
Watts per light bulb compared to 60watts per hour:
​
INC: 60watts= 1.5gals of water/hour
CFL: 12watts= 0.35gal of water/hour
LED: 8watts= 0.2gal of water/hour
