But what if they have missed something and the heating continues even after the Western World has crippled their economies to reduce the drivers of greenhouse gasses? The seesaw is finely balanced and if something as simple as albedo or a combination of other un-forseen variables still tip us into a heating path, then where are we?
But what if they have missed something and the heating prevents winter storms and takes the edge off the next Ice Age?

Comments from the fine article:

Quote:
As E-P points out the stability of 50/60HZ comes from the mechanical inertia of all the motors and generators spinning in the grid. Originally this was
'free' in the sense that as only spinning generators could make power (on a large scale) you got the inertia whether you wanted it or not.
As you add non synchronous generation the inertia declines. So you have to add inertia somewhere. Real or synthetic.
....
The first of these CAES plants were built to store cheap off peak power from nukes.
If you had a mountain you would use pumped hydro.
The salt caverns are also a geographic feature that can be exploited. No more no less.
At the moment all the seasonal storage of gas in the US (and quite a lot in Europe) is stored in such caverns,
Quote:
'In an article by Sonal Patel in POWER, the author focused on clarifying what that 1,000 MW of renewable power actually represents. The project could store up 1,000 MW of renewable energy year-round. It could be provided to "variability-challenged" Western power markets.

Patel also said that, responding to a request for clarification about the 1,000-MW figure attributed to the facility, which will comprise both storage and power generation, "MHPS said on May 31 ACES is still in the project scoping phase, and that the next step, which entails securing off-taker agreements for power, would determine the mix between renewable hydrogen, CAES, solid oxide fuel cells (SOFC), and flow batteries."

So, renewable hydrogen is not the only technology on tap. Three others are involved to serve the needs of 150,000 households for a year. The ACES initiative will deploy a total of four types of clean energy storage at utility scale. Joining renewable hydrogen are compressed air energy storage; large-scale flow batteries; and solid oxide fuel cells.'

storage

There's also a bit of Flywheel,Railcar storage,Underground gravity,cryogenic,and pumped-heat electrical storage.

And all of them add to the expense of renewables.

Added costs for energy storage and tons more transmission lines for infrequent energy sources being mpved to where its in surplus to where its needed is being completely ignored as long as it's riding on the back of fossil fuel power.

Look for something cheaper at scale: https://duckduckgo.com/?q=move_a_mountain_for_energy_storage

Quote:
The company Energy Cache is pursuing a different option for mountainside energy storage. In their system a series of scoops attached to a ski lift like system move up and down the mountain side. A each end of the transport system the scoop travels over and under a hopper. When passing over the hopper the scoops can depoisit graven into the receptacle and when passing under the hoper they can recieve a load of gravel from the receptical. In the energy storage mode the scoops receive gravel at the bottom of hill and deposit gravel the top of the hill. In the energy production mode this sequence is reversed. The gravel lift is powered by a reverisible generator/motor as is the train engine in the ARES system.

Ain't got any mountains around here.
Nearest are between 200 and 240 miles away.

Here is something interesting.
Voters are more worried about drug addiction, cost of health care, fake news, our political system, violence crime than they are worried about climate change.
Accordingto pew research.

Eric Dollard is still working, he will be at a conference in Idaho demonstrating Tesla technology:


At this time stamp, he shows Ecomodder-style animated charts: https://youtu.be/PkrzXUyvSDg?t=1122

In addition to validating Tesla technology (which he says will be used for communication since power transmission isn't compatible with digital tech), He's working on an earthquake prediction system and an AM crystal radio.

This is what our climate crisis looks like. Things are going to get rougher and rougher - and if we act decisively and in a big way - we might be able to slow the rate of decline.

We have caused a great big problem. A month's worth of rain in 24 hours ...

I'm not going to link directly in order to protec Ecomodder, but it's important to look at what the young folk think.

If you can find a site called Bit*chute and find a poster named soph, her last post on 2019-06-02 takes Greta Thunberg to task. I found it very informative. And amusing.
