Wood Species Energy BTU per Cord
Not all trees are created equal. Hard wood has more energy than soft wood does. The sapless, hardest woods are best for wood stoves. White Oak has double the energy of White Cedar.
The U.S. Forest Products Laboratory rated wood species energy in BTU per cord of seasoned, 20%-moisture wood, which I sorted with the highest-energy wood first:

Hello .. firstly I would like to send greetings to all readers. After this, I recognize the content so interesting about this article. For me personally I liked all the information. I would like to know of cases like this more often. In my personal experience I might mention a book called Generic Viagra in this book that I mentioned have very interesting topics, and also you have much to do with the main theme of this article.
To start with I would like to congratulate the cradores of this blog, mainly because when I read it I enjoyed it very much. A few years ago I attended a conference called guanacaste costa rica real estate, at that conference had many interesting topics. Perhaps readers may find no relationship between the blog and this conference, but if someday can attend, would realize that there is much to do with this blog.
I am taking a Thermal Solar class for Clean Energy, Green training and a homework assignment was to find out how many BTU's were in a cord or wood, (oak).
This has been very helpful information and a a great comparison chart of a lot more information. I will share this with my class and teacher. Thank you! This is very interesting.
