President Barack Obama was in Nevada touting his energy plan and touring the country's largest solar energy generator.
The Copper Mountain Solar 1 facility has nearly a million solar panels that generate power for 17,000 homes.
It was financed in part with $40 million worth of federal tax credits.
The president says it's part of his plan to diversify the country's "energy portfolio" and promote alternative energy sources like solar.
That brings us to tonight's number: 15.
According to an analyst at Pacific Crest Securities, that's how many years customers would have to commit to solar energy to break even.
Electricity prices are tied to coal and natural gas – not oil – and even though oil prices are high, natural gas is still low.
So you'd have to "sweat it out" for a couple of decades before you see returns.
But, even if you're willing to put in the time, solar energy won't work everywhere.
Right now, there are only three states: California, Florida and Hawaii with the right mix.
What do you think about the President’s energy plan? How "solar ready" is your hometown?
Would you be willing to commit to a 15-20 year “time horizon”?
