@Mastermind I think this could be sticky for future reference just my .02 cents.

I can convert it to a spreadsheet table with everything aligned and easier to read. Might take a reference at the bottom. I can rank by BTU or list wood species in alphabetical order. Let me know.
I did an Excel chart but it will not paste into a post correctly.

Yes, it will not. You have to convert it to a graphic image. The way I do that is print the Excel chart to Adobe Acrobat. Save the PDF to a PNG file. Load that to a picture host, such as Photobucket, and then copy that image to this website. Sounds like a PITA (and it is) but it works. If you do not have Adobe Acrobat, it may be impossible for a chart this big. A screen capture program might do it.

We get quite a bit of live oak down here. Takes a bit to dry but, it's worth it to us.

I think this chart is more accurate for cottonwood. Most charts say 15 to 17 MMBTU per cord. It all depends on where the tree was growing and which part was burned during the test.

Also, note something else: if you take the weight in lb of a dry cord (col. 3) and divide that by the MMBTU per cord (Col. 1), you get about the same number (132 to 133 lb per MMBTU) for all of the species listed in the table.

Yep. I always heard a pound of wood is a pound of wood. Almost all wood burn ratings start with the heaviest dry wood at the top

Yes, "a pound of wood is a pound of wood." Larger stoves that can swallow less dense logs will put out the same heat while burning them. Lots of people who burn cottonwood and willow love the heat that it releases and it's easy to light. It just takes a bigger log than oak to do it. They also love the flames. To each his own.

I recently told a customer that all I had left was cottonwood and that all my dense hardwoods such as ash, oak, and locust were sold. He said, "So what? Bring on the cottonwood. Dang it, I want heat."

I made the delivery to a satisfied customer.

You might like to take a look at this:

Recent Energy Prices per MMBTU
Coal – Powder River Basin – $0.56
Coal – Northern Appalachia - $2.08
Natural gas - $5.69
Ethanol tax credit – $5.92
Propane - $13.28
Petroleum – $13.43
#2 Heating oil - $14.74
Jet fuel - $15.48
Diesel - $15.59
Gasoline - $17.81
Wood pellets - $18.57
Corn ethanol - $23.46
Electricity - $26.31
Cellulosic ethanol from corn cobs – $30.92

These are pretty good spot prices and I admit they do fluctuate. For example, gasoline has been cheaper than propane recently. Suppose a cord of dry firewood averages 4000 lb and costs $300 delivered and stacked. That’s 30 parcels at 133 lb each, and each one produces a million BTUs. So, I figure that firewood energy today averages about $10 per MMBTU.

That's great work on the charts fellers, but I'd have to disagree with some of the drying times. At least for the East coast. West coast maybe , but not up here.;)
