Juan Cole: Five Signs Solar Power is Taking Over the World

The only energy source that has a hope of fixing this problem and of resolving the coming energy crisis is solar. The cost of solar panels is falling rapidly, raising the hope that we can put in enough panels quickly enough to avoid the very worst scenario of carbon-induced climate disruption. (I put in 16 Enphase microinverter panels at my place this winter and they generated 120 kilowatt hours in the past week; my house and electric car averaged 150 kilowatt hours usage per week last month; and that is in Michigan at the tail end of winter).
Here are some promising signs with regard to solar power that have recently been in the news:
1. Cheaper solar panels and more efficient wind turbines now produce so much energy that they pay for themselves quickly even if you add the cost of storage into the mix, and they also pay for the cost of adding more wind and solar. The Scientific American writes that Charles Banhart, a post-doc at Stanfords Global Clmate and Energy Project, told them: What were saying is that theoretically, it is now theoretically possible to have this perfect world thats just based on wind and solar. It adds, Rather than using existing stock fuels like fossil fuels, he said, renewables put out enough excess energy to fuel their own expansion.
2. The price of electricity generated by solar panels in India has fallen so much that solar is now competitive with coal. India wants to add 22 gigawatts of solar by 2022, but is already looking like it will do at least 3 times that because of falling costs. In twenty years, India will be the country generating the most new demand for electricity in the world, surpassing China.
