The Indian government says the country receives more than enough solar radiation to meet its annual energy needs
Sometimes the learning curve is shallow and sometimes it is steep, but it always seems to be there.
In the case of PV cells, it’s quite steep: for every doubling of output, cost falls by over 20%.
And this matters because output is increasing so fast: between 2010 and 2016 the world produced 100 times more solar cells than it had before 2010.
…
As early as 2012, PV projects in the sunny US states were signing deals to sell power at less than the price of electricity generated by fossil fuels.
That was the sign that solar power had become a serious threat to existing fossil fuel infrastructure, not because it’s green but because it’s cheap.
…
But the learning curve tells us that the ultimate triumph of solar PV seems likely: it is getting cheaper as it gets more popular, and more popular as it gets cheaper.
