If you liked that, you're going to love this. It's almost exactly the price tag to switch - completely - to renewables.

I know, I know, many studies, many different amounts, but come on! Let's try!

How about we take.that and spent it on climate change mitigation instead

This is disheartening.

Here in Alberta, Canada our Premier (moron with the biggest hat) has legitimately given hundred of millions to big oil companies under the guise of well clean up, future contracts, more work etc. etc. If you have a Texas hat, walked up to Danny Smith and stoof there with your lad in your hand (real or not) and demand money because you're oil, she'll ask how much and pull out my wallet.

most of these companies take the money and leave, not doing a fucking thing afterwards. Doing even less, if the money was to help clean up their fucking mess.

So there's that.

Difficult one for the Indian government - more business = more power required, but subsidies not acceptable

These subsidies are mostly implicit. Particularly in countries like the US, Canada etc. Implicit are basically environmental costs. The only countries that government actually is subsidizing growth to any extent are countries like Saudia Arabia, Iran, Russia. To a lesser extent you have Western nations like Germany and the UK that are subsisting energy to your house so you don't pay so much.

In other words the biggest cost or implicit subsidies as they call it is not subsidies to companies but the environmental costs us consumers do not pay to use energy.
