renewables are largely unreliable as well so you must add massive storage costs which makes them even more uneconomic

Don't forget that even if you could run everything on wind and solar, you still need to build and operate backup systems to provide electricity when the renewable sources don't. Since the worst case is having ZERO renewable power (night time with no wind) the backup systems need to be big enough to run everything all the time.

So adopting wind and solar as 'primary' sources of power comes with an added cost of ALSO building a hydrocarbon based system big enough to run everything anyway.

The costs for a truly functional and reliable "renewable power grid" are going to be at least twice the cost of current hydrocarbon based systems, and at least half that capacity will sit there unused most of the time.

On the basis of sunk capital costs alone most renewable energy makes no sense.

PS. For those who haven't seen it before, the development of liquid metal batteries for power storage at scale is making some significant strides. Time will tell if it is capable of making intermittent sources practical or not.
