Solar now being the cheapest energy source made its rounds on Lemmy some weeks ago, if I remember correctly. I just found this graphic and felt it was worth sharing independently.
There's a lot more nuance to this than most people will admit.
Net metering is 100% unsustainable, when renewables become a big enough chunk of the grid generation mix, they often generate when no one needs the power. Forcing the grid to accept that power and even pay the homeowner a premium for it is a perverse incentive. Effectively what it does is allow solar array owners to avoid paying to maintain a grid they still use, and since the rich trend to go solar first, the poor are left holding the bag to maintain the grid for everyone.
