What happens if politicians dont stop lying? Houston, we have a problem.

The first step to fixing the problem is remove the power system from
the control of politicians and give control to the engineers.

The second is to force everyone to read a paper by the Upsalla
University's Global Energy Group on oil and coal reserves and supplies.

Take notice of the profits of the major oil companies.
Note the reports that give a suspicion that we have reached world peak coal.
Then design our power generation with these thoughts during the next
twenty years by which time there will be no point in arguing.

It is inevitable that wind, solar cannot do the job on its own.
Forget batteries, to store for 5 overcast still days means
you have to spend six times as much on generation & batteries.
Pumped hydro is a good scheme but you need more than twice the
generating capacity of the daily electricity consumption if it is to
be the only backup. That storage can be multiple weeks worth of power.

When conventional plants go down they take a while to stop spinning,

Once their speed falls they are well already disconnected from the grid.
Multiple machines are running in parallel and when one attempts to
go slower it is driven by the others. At that time it is no longer
providing its rated power and if the power to keep it up to speed
is too much it is disconnected.
Up to that time they are all rotating at the same speed.
ie they are no longer in sync.
