The largest growth in consumption for residential and commercial has been in space-cooling (air conditioning). For the US 30% of the overall power generated is used to power space-cooling.

This has the side effect of making cities hotter. Mix that in with global warming and this will make space-cooling to continue to be the largest growth factor for electricity consumption in the years ahead.

Here is an article I wrote detailing this:
Power Struggle: Plugged in to Global Cooling

The two are not unrelated.  Computers throw off a lot of heat, especially if you have a lot of them, and they are more vulnerable to heat than human beings.

My office did not have air-conditioning until we computerized. I bought an air-conditioner for my computer room because I was afraid the heat would burn it out during the summer.  Before I got a computer, I lived here 10 years without an air-conditioner.
