Here’s the website for the IEEE Spectrum Special Report: Water vs. Energy. From the “Water-Energy Nexus” section:
Without water, we’d have practically no energy. Without energy—and therefore cars, planes, laptops, smartphones, and lighting—we wouldn’t be doing much. In almost every type of power plant, water is a major hidden cost. Water cools the blistering steam of thermal plants and allows hydroelectric turbines to churn. It brings biofuel crops from the ground and geothermal energy from the depths of the Earth. Our power sources would be impotent without water.
