Last week, Massachusetts announced it had reached its goal of obtaining 250 megawatts of power — enough to power multiple mid-sized cities — four years early.
The main reason is China, which has so thoroughly flooded the global market with cheap parts that today, Europe slapped them with a new tariff.
But there are other signs that solar power is set to take off.
We’ve compiled some of them here.
In the past few years, the doubling of solar capacity has resulted in a 40% reduction in solar costs.
Mostly thanks to China.
Solar has high start-up costs, but give it enough time and it becomes the cheapest power source out there.
Warren Buffett recently purchased the largest solar development in the world, a set of arrays in California.
Households in many countries can already get solar cheaper than the price of plugging into their local grid.
Residents of the Southwest U.S. reached this point last year.
During peak demand times in some countries, solar is most cost-effective. Here's what the demand cost curve looks like in Germany on a winter's day.
'This peak effect has resulted in some gas plants in Germany running in 2012 for no more than a handful of days, with resulting profit warnings from associated utilities,' Citi writes.
And the amount of new solar New Jersey's largest utility, PSE&G, installed last year was third-most in the country.
As Citi notes, no source of energy reigns forever. That means that a change to our current system will come inevitably.
As some say, 'We didn't leave the stone age because we ran out of stones.'
