11 of the 12 most polluted cities on earth are in India. They need to build a lot faster given coal is still 3/4 of their energy generation. The US is a laggard on solar as a percentage of energy generation, and even the US has a larger share of its energy derived from solar than India does.

India's air pollution problem is only partially due to power plants. Much of it comes from things like cooking fires, agricultural burning, and combustion vehicles. Closing down coal would be a step forward, but wouldn't solve the problem alone.

Pretty much off topic by me but:

Do you know what is the total surface area of currently installed solar panels by SolarCity?

Alternatively the largest total area solar panels operated by a single entity?

(it's for an astronomy idea I have)
