Maybe people could club together and form some form of group which provides that minimum requirement for the whole area. You could perhaps have an equal say in the group, and have a meeting every few years where you elect some people to run the thing on your behalf.

My guess is it'll meet the same fate as municipal broadband. (i.e. It is explicitly outlawed in Texas.¹)

Or the state government could implement a regulatory regime that ensures its citizens have reliable electricity. A feat the other 49 states seem to have mostly accomplished.

In my country the price of roof mount solar is now under €2000 for 10kWp. That includes government subsidies, however they are not that high (€350 per kWp).

Texas is a much richer economy than where I live, so I see no reason why it couldn't be a requirement, at least for single family homes.

With a subsidu of €350 per kWp, does that mean the government subsidizes €3500 for the roof mounted solar that you quoted at €2000 for 10kWp?

If so that seems like a pretty substantial subsidy to me, the government is covering around 63% of the total cost.

We must have very different definitions of urbanized. Hundreds of square miles of suburbs doesn't quite count as "urbanized".
