OK, for the simple answer, find a chart with the various species of wood and the amount of btu's per cord (search - btu firewood chart). But you want the kwh so divide btu's by 3412 to get the kwh equivalence (search - fuel energy equivalents calculator).
For example, one cord of good mixed hardwood averaging 24 Mbtu's, divide by 3420, is 7033 kwh, given no losses. Like calculating the wind speed and swept area, it's the maximum potential, a starting point before figuring in losses to well... everywhere energy can be lost. You will have to figure out some of the losses, or efficiency on your own. Burning wood, to boil water, to create steam, to turn machinery, to generate electricity, to charge batteries, will be less than efficient. But undoubtedly you will learn things from it, and probably have some fun on your journey too.
