Net Zero Emissions of Carbon is a Myth:
The reasons they are a myth is because
They are reliant on the pipe-dream that there is some affordable way to store surplus electricity at scale.
The reality is that many of them have kept the lights on only by using existing fossil fired stations as backup for periods of low wind and sun.
Efficient combined-cycle gas turbines are being replaced by open-cycle ones because they can be throttled up and down easily to back up the rapidly changing output of wind and solar farms.
But, open-cycle gas turbines burn about twice as much gas as combined cycle gas turbines. Switching to high-emissions machinery as part of an effort to reduce emissions is, frankly, madness!
Under net-zero plans, all nations will need to generate many times more electricity than they now can, as the large majority of our energy use today is delivered by burning fossil fuels directly.
Power prices will soar, making more or less everything more expensive, and there will be frequent blackouts.
Building even more renewables capacity will not help: even ten or 100 times the nominally-necessary “capacity” could never do the job on a cold, windless evening.
Wind farms cost about $1.5 million per MW so the cost of battery storage would be astronomical: 80 times greater than the cost of the wind farm!
A major additional constraint would be that such quantities of batteries are simply not available. Not enough lithium and cobalt and other rare minerals are being mined at the moment.
Some countries are gambling on hydro pumped storage.
Many pumped systems have been built in China, Japan and United States but they have storage sufficient for only 6 to 10 hours operation.
