I expect that all the true believers will, by now, have parked their vehicles; turned off their thermostats; flipped off their main breakers and started harvesting their own locally grown (no transport required) veggies which they will eat raw.
If they're not doing that then they're part of the problem and have no right to act "superiour".
Hopefully they have put solar on their roof and bought a electric car that's powered by it. Hell, when you think about it that isn't a bad idea.
The only thing stopping it is the price of solar to be able to power your home and car.
Yeah -- the only thing stopping you then would be a rain/snow storm, your lattitude or night..
