"LPG emits 15 times more CO2 (carbon dioxide) per kg than wood" Interesting. But "per kg" is the wrong comparison. A kg of coal provides much more heat measured in BTUs than the same weight of coal. It'd be interesting to know the more relevant comparison, which is C02 per BTU for coal & Wood. For the same heat in BTUs, which releases more Co2, wood or coal? The comparison is difficult partly because wood is typically measured by volume (a 'Chord') which does not correlate to weight or BTUs. For the same heat in BTUs you'd burn 2x as much wood by volume if you're burning cottonwood or oak. The base problem is there isn't nearly enough square miles of Canada to grow enough wood to replace much fossil fuel. - tilyou1@yahoo.com muextension.missouri.edu [different types of wood] gulland.ca I don't understand this, but it supports your theory that burning wood is okay from a Co2 point of view: "Wood is defined as a renewable energy source, along with wind, solar, hydroelectric and geothermal energy. As one of the few renewable energy sources—each of which has regional and/or site-related limitations—wood can at least be seen as a potentially strategic fuel. Canada's reliance on fossil fuels such as oil, gas and coal makes it among the world's highest per capita emitters of carbon dioxide, the principal greenhouse gas. Both energy and forestry scientists agree that, provided harvesting is conducted in a sustainable manner, the combustion of wood for energy uses contributes no net carbon dioxide to the atmosphere when the normal forest regeneration period is considered. The 1992 United Nations Conference on Environment and Development (UNCED) in Rio was the site of an historic international agreement to stabilize greenhouse gas emissions at 1990 levels by the year 2000. One of the UNCED documents states: The need to control atmospheric emissions of greenhouse and other gases and substances will increasingly need to be based on efficiency in energy production, transmission, distribution and consumption, and on growing reliance on environmentally sound energy systems, particularly new and renewable sources of energy.1 Wood energy could serve as one of the strategic options in the effort to reduce greenhouse gas emissions from fossil fuel combustion."
