Solar energy is a clean source of energy that neither emits greenhouse gases nor requires drilling deep into the ground or the ocean. But both the construction and the deployment of large-scale solar power installations do have some impact on the environment, especially in the desert where they are most typically located.

In Nevada, the sun’s rays provide an abundant and clean form of energy but harnessing that potential can come at a cost. Water is needed to clean solar panels and mirrors as well as to cool solar thermal power plants, but water in the desert is a scarce resource. Consequently, to ensure that solar energy is a sustainable source of energy in arid desert environments, NEXUS scientists are investigating various ways to minimize water use while maximizing solar efficiency.
