Water resources are threatened as companies compete for control of these resources. This challenge is even greater in arid areas with high density and volume of population.
Water is used in thermal power generation and hydroelectric plants. Electric power generation is responsible for almost 40% of freshwater withdrawals in the US.
Agriculture accounts for approximately 80 percent of the United States' consumptive water use and over 90 percent in many Western States. In 2015, this was measured at around 200 Billion gallons per day in the US.
Water is essential to fuel extraction, production, refining, processing, and transportation. It takes 5 barrels of water to produce 1 barrel of oil. This totals around 4 Billion gallons per day in the US.
