> What's the upside of moralizing energy consumption, especially once it's 100% renewable.
Because of the reason I just explained above. 100% renewable energy does not mean that producing that energy does not have an environmental cost.
> Why not just let the market decide? If I'm paying for it, why does anyone else get a say in how I use it?
Because the "free market" does not internalize externalities (costs to shared resources like the environment, air quality, public health, etc.).
Focussing on pricing those externalities (tiny as they'll be in a 100% renewable world), through laws + policy, is a better strategy than trying to convince people not to use their electricity for <thing I personally don't value>.
