The sun's energy hitting a photocell that is not turned into electricity is also waste heat, and that's waste heat that's very hard to put to use.

Sigh with the political screes.

How did you make it past elementary school without learning that there's more than one way to increase revenue.
In the case of taxes, yes- you can increase the final rate of taxation.
You can also raise the amount of money taxed.

That's the problem with political screes. They almost always involve someone who would otherwise be smart, making themselves look stupid. Do better.

Wood contains a lot of minerals. Much of this remains in the ash, which is part of the reason some land is cleared by fires. Some of the minerals are airborn, and that's pollution.

Because that's only something you can do to a limited extent. Continue doing it, and you'll run out of paper to print that money on before you've got enough for a loaf of bread.
The Fed exists to smooth over panics. Nobody thinks you can print your way to replacing the economic ladder.

In this hypothetical universe you've contrived, if your robots can be maintained by less than millions of workers.... Sure.
The supply line for robots is quite large.
No rich people are capable of being an economic island, yet. They need to get much bigger still.

Ya, I should further qualify my assessment with "economic collapse, if you've still got a somewhat free market, democratic, and capitalist society operating it."
L'état, c'est moi, literal slavery, or financial institutions knocking over governments they don't like (domestically I mean, foreign- well that's just Tuesday) changes it.
There's no bottom needed if you've got them at gun point.

There have been some scientific reports that the sound from wind generators is detrimental to whales. I don't know how valid those reports are, but they're something to be considered.

Conservatives want the U.S. to be self-sufficient with petroleum. They want Europe to not have to depend on petroleum from Russia.

40 years ago leftists were having hissy fits about diamonds from the Union of South Africa. Petroleum is far more important and the Islamist and Russian governments far more dangerous.

It can be overcast for weeks at a time, and low wind for a few days. With that in mind, your analysis still looks like a valuable contribution, but a bit too optimistic.

Pumped hydro efficiency is in the range of 70% to 80%. That's a lot of waste. The the ability to make pumped hydro depends heavily on local geography. Substantial capacity would require building new reservoirs, and many environmentalists are already unhappy with the reservoirs already in place. They aren't maintenance-free, but I'd guess the effective mean time between refurbishments is not much different than lithium batteries.

Loss of heads is part of. Economic collapse is another part of it.
You can't get rich anymore if there's no one with any money to spend.
Ultimately, way down there in the dredges, someone with not a lot of money needs to buy something that leads to money getting to you.
You can only hollow out the bottom so much.

No, it absolutely is a nonsequitur.

Liquidity is very different than "the economy".
If you add enough asterisks, they can be pretty analogous, but at the worst, they're almost entirely disconnected.

History is littered with the corpses of seemingly immortal companies. The East India Company is centuries gone. General Motors went bankrupt and the name now exists on top of a new corporation. The Great Atlantic and Pacific Tea Company is a shadow of its former dominant self, and Sears Roebuck is dying. Standard Oil and Bell (AT&T) were shattered by the U.S. government.

lol. Commenting with lol is lame... but I had to. lol.

Tens of billions of dollars?
The US pulls in almost 5000 billion dollars of tax money per year.

I don't think 10 billion dollars were going to change our "high gas prices" (I'm going to find that particularly funny if you're European) and "high tariffs" (I guess they're higher than the EU blank 20% on Chinese imports?)

I still think you might just be trying to swing your politics around.
