It is a little bit embarrassing that this is from a former US Army General, as I was a prior Corps of Engineers officer, but we came to accept long ago that the Air Force got the smart Generals, and we (the Army) had what was left.

Would you like to go down this and see how much is not correct?

The real numbers wind up very favorable -- but so much so that the Oil, Gas, Nuke and related Industries will be largely wiped out.
how? How can renewables replace non renewables?

Look at the numbers and give us the answer.

Currently NON HYDRO renewables account for about 13% of generation in the US or about 500 billion Kwh out of 4009 billion installed.

They'll replace much of the fossil fuel use, but it won't be near 100 percent. It'll take a long time. It takes about 30 years to replace the vehicle fleet. The useful life for power plants, solar farms, and wind farms run from 20 to 40 years. The efficiencies will take time to materialize because of the existing infrastructure. Rare earth minerals will be substituted by other rare earth minerals or other minerals or alloys.

Do you think we will ever get recharge time below 15 minutes? As EV's are right now I could function just fine driving around town but I would never take one cross country and I drive cross country fairly frequently.

I think electric cars and batteries will be mostly subscription service and people will just swap out batteries. The long-haul trucks are probably going fuel cell and biofuel in the long run.

Have we not done this 100 times?

THAT was 2020. We agree that you are expert of what Once Was. You can correctly tell US all about looking in the Rear View Mirror.

Driving FORWARD is rather different than looking in the Rear View Mirror. The Generation Mix of 2020 you are looking back at goes back to sources now 50 years PAST included, but still existing at near end of Service Life.

It is NOW 2021.

What is being built ahead? ZERO Coal, (near) ZERO Nukes, Gas Under 20%, and near 80% renewable?

This is your same site source (EIA) showing what is Being Built NOW -- so this points to what we will have 10, 20, 30 years or more into the Future.

Turn around a take a look out the Windshield ahead?

What you are asking about is already happening.

There is no need for Perfection.

As we saw in Spring of 2020, just a 10 to 20% drop in demand can wipe out the Oil Industry.

Recall Texas Oil at Negative Numbers?

(and for about the 1000th Time.) ZERO Rare Earth Elements or Materials are required for Silicon Solar PV (the dominate New Generation Source).

what are you babbling about? You don't have the answer so you dribble hyperbole down your chin like a geriatric in the nursing home...
You don't have a clue how to replace 3000 billion plus Kwh of generation do you? do you even have a clue as to the scale of construction required?

the eia data link I provided pretty clearly stated:
Preliminary data as of February 2021

Green energy will fail to meet current energy demand, but it will eventually be all we have left. Using less energy is the simple answer that fake greens don't want to hear.

We have already known for the past 10 years.

4E15 kWh per year / 2000 Hours Run Time per year = 2E12 Watts (or about) of Silicon Solar PV.

2E12 Watts spread out across 40 Years (Service Life) means about 5E10 Watts per year.

Costs about $50E9 (US $50 Billion per year).

Let Existing Coal, Nukes, and Gas fall off along the way.

It is ALREADY happening.

Yes. A+ That was a REVIEW of the Calendar Year 2020.

A look in the REARVIEW Mirror.

Did you hit the other link? That will tell you the NEW Plants we are building 2021 and beyond.

The FUTURE as it is.

It is mostly Renewable and more so all the way AHEAD.

It does not have to hit current demand. Just about 1/3

Existing Fossil is SO LOSSY that it only takes about 1/3 of the present energy inputs to totally replace it.

Have you ever looked at the Lawrence Livermore National Labs Sankey Energy Flow Diagram?

You can see all the present Energy Inputs on the Left Side. And the resulting Work Output on the Right Side.

See where it says "Rejected Energy" on the Right Side?

That is mostly Heat Loss due to burning Fossil Fuels. That Heat Loss all goes away with Full Renewables.
