I was surprised by this bit: 47% of global energy is spent on indoor heating, and 42% of that specifically for residential heating. Seems like a lot to me. A cynic may say that, if that's true, then global warming would be self-correcting since, as the world heats up, fewer people will need heating.
- maxerickson 12y agoIt's not true. According to the EIA, 11% of global energy consumption went to residential uses in 2007: http://www.eia.gov/forecasts/archive/ieo07/enduse.html http://www.eia.gov/forecasts/archive/ieo07/enduse.html So it would be difficult for residential heating to be more than 10% of total consumption.
- gwern 12y agoIf you google the stat, it seems to be a little more plausible: 47% for heating and cooling. it is not obvious that global warming would be a net savings of energy: much of the world is already very warm and relies heavily on air conditioning.
- maxerickson 12y agoThe only plausible way to reach 47% is for "building energy consumption". So excluding things like industry and transport.
