There are too many interested parties involved in the energy sector. The only common sense I can think of is solar+storage at the single building level and interconnected through smart grids with neighbours.

But that leaves out the government and all those interested parties so we're never ever getting that.

Sure.

But at the scale of a city or state one home uses close enough to zero power that it being a net user or net producer of electricity is irrelevant.

Scale up to tens of thousands of homes and suddenly you need an organising body approximating government to manage those homes being net users or net producers from moment to moment.

Additionally most cities tend to want to have commercial and industrial users of electricity, and energy more broadly. Your home solar & battery does approximately nothing to help them, and if any of the data is to be believed has resulted in electricity prices increasing for everyone.

While I do not know if the following is relevant for the Carolina Long Bay area, and while neither Republicans nor Democrats can be trusted, it is not without precedent for offshore wind turbine projects to be disallowed due to radar concerns.

Other possibilities than radar concerns is that the stopping of the project here hinders corruption, or is corrupt itself, or it moves corruption around (as in both the old project and new project was corrupt). Whatever the case, a way to avoid corruption would be helpful. Perhaps like making it market-driven and contest-driven as much as possible. Solar and wind is already significantly cost-efficient and market-driven despite their significant drawbacks like not producing energy consistently and on demand. If the main challenge is creating domestic production of wind turbines and solar cells instead of being reliant on other countries and without state support ending up being mired in corruption, perhaps some bidding and contract process that moves the financial risk onto private companies, such that the government never pays in advance, could work.

I agree with posts here saying that a mosaic or plethora of energy sources should be used. Wind, solar, fossile, nuclear (for big countries like the USA at least), geothermal, etc. In general, energy companies should not be focused on just one kind, but lots of kinds.

And in the winter in the North people are just supposed to freeze?

That leaves a lot of free energy sources untapped - especially hydro.

That’s not a good idea. Millions would be left without electricity.

Even in Texas/California photovoltaic output in the winter is measly, anywhere more to the north and it's effectively inexistent. Solar+storage requires massive overprovisioning, to the level that it's cheaper to burn literal money.

Windmill farm outputs tend to dip during summer and peak over winter. With a given minimum power output windmills + photovoltaics + storage is massively cheaper per unit of yearly energy. Of course, if you value any semblance of network stability.

Solar+storage is clear path towards either guaranteeing reliance on fossils or brownouts. The smart energy meter you got that encourages running the washing machine during cheap hours will ensure that you voluntarily go dark during undersupply as the cost will skyrocket.
