Environmentalists come up with the most expensive energy solution.
Monopoly site regulated utilities have a statutory right to a return on assets. The amount and mechanism for determine the amount varies but essentially the more a utility invest the greater the absolute return.
In ohio there was a fiasco called Zimmer. The utility blew a billion on nuclear and could not recapture the investment so they spent another billion converting the nuke plant to coal. The state then let them recapture the 2 billion. Ratepayers essentially paid 2 billion for what should have been a $800 million coal plant.
“Geen energy” has the same payback.
