The Oil Drum

As the shortest day of the year is just ahead, and colder temperatures abound, (at least in the North), I thought I'd edit and repost an analysis on home heating I ran last summer. (That post was followed by quite a good discussion)

A short fifty years ago, people heated their homes in winter with coal. A hundred years ago and before, people living in cold climates largely stayed warm in winter with firewood. Today, in a country (and planet) with vastly more people, we heat homes in northern climates largely with high quality fossil fuels, specifically natural gas, heating oil, and propane. Trees, a less energy-dense form of stored sunlight than oil and gas, have recovered a good part of their former % of landcover in the US, despite being still used for paper, wood, furniture, pulp and some heat. Below is an analysis of how the US residential sector heats its homes, how large are our forests and how much they grow and how much wood we could use for heat, after fossil fuels decline.
