This is exactly it. All Trump and the GOP have done is KILL clean energy projects left and right to cut deals for their polluter buddies.
To actually have real negotiations on permitting reform, they must first stop their war on clean energy.

I'm dense when it comes to finance, so the fact that I got to a point of understanding how utilities earn profit and why they should or shouldn't earn less means you can too. I stayed up till 3am trying to explain in an accessible way. Hopefully it was worth it!

Another way to reduce electricity prices? Shifting from for-profit, investor-owned monopoly utilities to municipal utilities or member-owned co-operatives would save about 15% on electricity bills, averaged over locations and customer classes.
8. For-profit utilities charge 14% more (13.3 c/kWh, 2023 average) than cities (11.7 c/kWh) and 16% more than rural coops (11.5 c/kWh). This trend is accelerating: For-profit utility prices rose 2.7 c/kWh from 2019-2023, 225% more than cities (1.2 c/kWh) and 270% more than coops (1 c/kWh).
