Water Risks on the Rise for Three Global Energy Production Hot Spots
Energy runs on water. In fact, among industries, the global energy sector is the world’s largest water user. Almost all forms of energy production and power generation depend upon water for their operations. This tension causes stress in both the energy and water worlds. Three-quarters of energy respondents to a 2012 CDP Global Water Survey confirmed that they experienced water-related ...
