Are people still alive who believe the world is flat? Investments in wind, solar and geothermal energy sources have tremendous paybacks over the lives of the investment. The return on investment is estimated to be 30 percent.
Location, however, is crucial. One needs wind, sunshine and underground thermal waters for putting the resources to work. Nevada is fortunate. There are ample resources across the state for all three energies.
Will wind and solar energy resources entirely eliminate traditional power generation? Probably not for decades; until energy can be stored for use during periods of calm or between sunset and sunrise. But other forms of renewable sources — geothermal, hydropower and biofuels — are available for around-the-clock use.
Renewable energy now supplies 10 percent of this nation’s electricity; since the world is actually round, we can expect that percentage to increase dramatically.
