All to produce more carbon contamination in cities that can not handle it, cutting down less carbon holding trees, to not really produce all that much energy, and burning the equivalent of a couple gallons of gas to get it.

That said, the supply did increase after that as lots of little producers took up the slack.

What would be your ideal heating system here? The one that will be useful even after a big earthquake in the middle of an abnormally cold winter.
Electric heating, with a backup generator if cash is no problem, the generator would be useful for other things too. I guess a gas bottle supplied heater is the cheapest back up, you can use the same gas bottle for emergency cooking facilities. Hell you could use a cooker for a inefficient way to heat your house in an emergency too.
