This is slightly outdated but you can see the potential problems for Las Vagas running out of electricity and that part of the country because of drought that could be the new normal.
"Under pressure from the region’s growing population and years of drought, Lake Mead was down to 1,087 feet, a 54-year low, as of Wednesday.
If the lake loses 10 feet a year, as it has recently, it will soon reach 1,050 feet, the level below which the turbines can no longer run.
Those hydroelectric generators produce cheap electricity for the Metropolitan Water District of Southern California, which is responsible for pumping water across the Colorado River Aqueduct to hydrate much of Southern California."
