I'm a writer, and I recently asked for a couple of people to help me out with an article that I'm writing on heating with wood heat. You guys were great, and I got a lot of help. But now I'm looking for some technical details about wood burning... Basically, I want my piece to be able to say that "wood heat is the most environmentally friendly way to heat your home". But...I need some stats/research/hard facts to back me up. Can anyone think of any studies or well-researched articles/websites that have done comparisons between the "environmentally friendliness" (or something similar) of different types of heat? Basically, my main reason for posting this is that I need some facts from a reputable source that I can quote from. I know this is a heated topic, and many people have different opinions on what constitutes "environmentally friendly". Do you think it's even going to be possible for me to find any hard, undisputed facts on this topic? One more thing...when comparing geothermal and woodheat, do you think that geothermal is "greener" (if you ignore the cost difference)? I've read that geothermal may not necessarily be the most efficient option in really cold climates? Any advice and links that you can share would be appreciated. Best, Laura-Jane Professional: www.laura-jane.com Personal: www.whimfield.com Edit: Two factors that I should mention: 1. I would like to ignore "cost" as a factor in the comparison; 2. I'm talking about heating in cold climates. Thanks again!
