Stop making up non-sense that have zero basis in reality.

The costs are fairly well captured in LCOE of these various sources of electricity. Questions like "How many year it lasts" is especially well captured.

> How many years do these batteries last.

For grid storage? Probably 1-3 decades. They'll have excellent battery management systems, chemistries that are optimized for longevity rather than energy density, they won't be fast charging/discharging, they'll probably never be discharged to 0%, mostly above 20% probably, which is also very gentle for batteries.

My EV battery is on its 8th year now with very little degradation. That's with primitive cooling (air cooling), older battery chemistry and fairly many charge/discharge cycles, including many deep discharges, since the EV battery is tiny (27kwH).

> The batteries end up in toxic waste dumps.

Completely false. Battery recycling is already happening at massive commercial scale, and reaching near 100% recycling. From consumer products like Apple iPhones to car and grid batteries. Car and grid batteries are particularly easy to recycle since you get huge bulk of identical cells.

Think about how insane it is to even consider this a disadvantage for batteries. How insanely many tonnes of coal will a coal power plant have burned in a decade? All that mining is gone forever. With battery materials mining, we'll eventually have enough materials for all the batteries we could ever need.

> All the solar panels end up in the garage.

Solar panels are a bit trickier, but that's also starting to ramp up at a commercial scale.

EU is already well ahead with regulations targeting recycling of these things. And given what's already demonstrated commercially, there's no reason to think 100% efficient recycling won't be the reality in a decade or so.

> what happens if there is ash in the air for a month and no solar can be provided?

Over a whole continent?

In France several of the supposedly reliable nuclear reactors went down at the same time a little while back. Huge amount of power went offline. They got by just fine with the help of their UK and German neighbors.
