The Las Vegas Valley Water District pays residents $2 for every square foot of grass they remove and replace with desert landscaping.
Las Vegas seems to be on a roll with renewable energy.
Next month, Acciona Solar will begin pumping power out of Nevada Solar One, a solar thermal plant with 184,000 mirrors arranged to focus the sun's energy on a metal tube filled with oil that's encased in specialized glass. The sun heats the oil to 750 degrees Fahrenheit and then the oil gets transferred to a heat exchanger where it makes steam, cranks a turbine, and makes electricity. The plant will produce enough power for 15,000 homes or 22,000 hotel rooms, said an Acciona spokesman. Check out a few photos here.
