Last week, an energy analyst at Deutsche Bank came to a startling conclusion: By 2016, solar power will be as cheap or cheaper than electricity from the conventional grid in every state except three. That’s without any changes to existing policy. In other words, we’re only a few years away from the point where, in most of the United States, there will be no economic reason not to go solar. If you care about slowing climate change or just moving toward cleaner energy, that is a huge deal.
And solar energy is already going gangbusters. In the past decade, the amount of solar power produced in the United States has leaped 139,000 percent. A number of factors are behind the boom: Cheaper panels and a raft of local and state incentives, plus a federal tax credit that shaves 30 percent off the cost of upgrading.
So what’s the holdup? A few obstacles: pushback from old-energy diehards, competition with other efficient energy sources, and the challenges of power storage and transmission. But with solar in the Southwest already at “grid parity” — meaning it costs the same or less as electricity from conventional sources — Wall Street is starting to see solar as a sound bet. As a recent Citigroup investment report put it, “Our viewpoint is that solar is here to stay.”
