Like most of the articles that cover this approach this subject, it manages to ignore the flip side of the equation.

Everyone focuses on how much it's going to cost and how much we're going to spend.

It costs a trillion dollars?

So what? When we "spend" money we're actually transferring it. Someone else is producing what we buy.

If we "spend" $200 billion dollars on wind farms... that's $200 billion dollars that's paid to the people who make them and install them. Part of that $200 billion dollars is spent on raw materials and components and generators and things produced by other companies and people.

And the money paid to all of those employees is going to be spent again, on leases and rent and car payments and food and so on.

That $200 billion dollars is money pumped directly into the economy, with a significant multiplier effect.

The same misconception occurred when we talked about money spent on space. But we didn't take all of that money and just shoot it into space. The rockets and systems were made here. The engineers and technicians were paid here.

The money was spent here. On Earth.

Further, solar and wind farms and power transmission/grid upgrades and pumped hydro and so on are all projects that have to happen here, on the ground in the US.

Those jobs exist here. The money is spent here.

There's a trillion dollars worth of opportunity out there.

Why aren't we dong it?
