There are 2 main things blocking this: Zoning issues. A lot of states have restrictive zoning that makes energy installation hard[0]. And money. (Although he Inflation Reduction Act will help[1], at least for windmills.)

Since the 2nd problem is money, Bloomberg could have helped here - all he needed to do was invest all this money into buying and installing windmills. But he didn't.

Warnings are worthless, activism is worthless, political posturing is worthless.

The only thing that actually matters is private investment (and government can help make that attractive). Provide tax credits or loan guarantees for new energy investments (the bipartisan Inflation Reduction Act is a good step).

My advice for Mr. Bloomberg? Take this money and start a public investment company, anyone can join him and invest, and he takes every bit of the money and starts installing windmills and solar. Use the proceeds to install even more.

If he put out some long term contracts for windmills parts he could dramatically boost manufacturing[1].
