We know that the two resources are connected: We need water to produce electricity, mostly for thermal power plants (though we are going to put that aside today). We need energy to pump water out of the ground, treat it so it is potable, and then re-treat it after we use it to shower or wash clothes. We also need energy to heat water in our homes, businesses, and industrial facilities. Recognizing these intersections opens up opportunities for utilities and businesses to save more energy and conserve more water, while helping policymakers and regulators design more strategic and cross-cutting policies.
