Worked in energy as a quant a few years back: the current 'greening' of the grid is nothing of the sort. It's just a cash grab by creating extreme volatility in energy prices. On the right (wrong) days you had swings of $10,000 USD within 5 minutes of each other.

The net result was the grid being taken over by the government after a series of rolling blackouts in a number of states and letting everything rip. All this is was directly attributed to _one_ coal station going offline unexpectedly and losing the baseload it generated.

I can write a book on how fucked the market here is.
