If you want to have an argument, try using arguments. Quantitative ones, like in https://escholarship.org/uc/energy_ambitions

If you don't want to have a conversation, continue to use empty assertions and slurs. But count me out of that.

Your choice entirely.

That would be sure nice, but the hard numbers of the physical reality say otherwise.

If you think we do have 50 years I recommend to reexamine the data. E.g. https://escholarship.org/uc/energy_ambitions is pretty comprehensive.

Well, we don't even have 50 years. Net energy of oil liquids is projected to peak as early as 2025. So trying to address that by trying to scale up even more volume only makes the energy cliff steeper.

The goals of renewable should be quantitative substitution of fossil primary energy within less than 50 years.

The only current storage technology cheap enough if you happen to have the nice problem of having to curtail renewable production during peak is water electrolysis -- if you also happen to have the natgas storage and distribution infrastructure already in place.

MWh and GWh scale battery infrastructure isn't cheap at all. It will likely take a decade to have affordable 10 kWh scale domestic storage, and it will be most likely sodium, not lithium. 100 kWh scale, which is almost enough for seasonal demand levelling will still take pressurized hydrogen in cylinders.

Adding even 10% of renewables (minus biofuels since fake renewable) to primary energy use of major industrialized countries is by no means easy. Which is why world fossil fraction of primary energy use is nearly a constant.

Garbage reports like that do a lot of damage. Fraction of fossil in the primary energy use is nearly constant, and net zero is merely a greenwashing scam.

The cleanest EV is a pedelec. Better Wh/km than even subway or muni rail.

If you have a working, borderline efficient ICE keep it until it falls apart, only then buy an EV.

Remarkably badly written. Unless paid by the word count.

Except when it's dark and/or windstill. MWh and TWh scale storage is the opposite of inexpensive.
