@Dan, with all due respect, people are smart enough to self-enforce their power use -- it's called "paying your bill". If your bill gets too high, you reduce your use to match your desired expense for power. You don't need the Power Police to monitor your life.
As to solar and wind, since they are intermittent, unreliable, weather-dependent and have a low capacity factor they require some sort of reliable back-up. That normally is supplied by a coal or natural gas-fired plant. No coal plants are shut down due to an increase in solar or wind generation.
Get up to speed with nuclear power plants that consume used nuclear fuel - Integral Fast Reactor or Liquid Fluoride Thorium Reactor (LFTR) www.energyfromthorium.com. With uranium, just don't eat it and you'll be fine.
nucanuck: "population reduction will need to be at the core of any plan"- you sound like Jacques Cousteau - if you are true to your convictions, you will be the first in line to volunteer for that reduction, right?
Uranium supplies, like all commodities, are price-dependent. The greater the demand, the higher the price for a given supply; at a higher price, it becomes more attractive to extract that commodity than it was at a lower price. So practically, there is no limit to uranium.
I am in the solar industry but am not deluded into thinking solar can replace base-load power from nuclear, coal or natural gas. Of those, nuclear poses the least environmental footprint - in mining, siting land-use, emissions, recycling spent fuel potential.
