Solar/wind is the cheapest form of power generation by far. You just can't beat it because they don't have any fuel costs. Gas peaker plants will always make sense until we have enough grid scale batteries. They will hold on for now until the price of natural gas hits rock bottom. But with the current advances in low cost battery technology I see them becoming less and less necessary. They would probably already be dead if hydrofracturing hadn't propped up the cost of gas.

I think you've missed that all generators have upfront cost. That's why the monetary payoff time for installing solar is non-zero. Versus a backup generator you're paying 2-3x the cost upfront. And yes we know the running cost is almost 0, the maintenance is almost nothing, etc etc, but I could see that argument not holding as much water as we need it to.

		Loans transfer upfront costs into operating costs, thus making upfront costs largely meaningless for anyone with access to cheap credit.

		Are you talking backup generator vs solar for a home? If so, solar continually supplies power without paying for an input vs a backup generator which is only meant to run infrequently and is costly to run and requires you to pay for inputs and of course maintenance of an ICE. It's kinda an apples/oranges comparison
