Add wood as an energy meter. You can track wood in the following units:
- kBtu (thousand Btu)
- MBtu (million Btu)
- Tonnes (metric)
"Cord" is not listed as an available unit because a cord of wood can be different weights (depending on how much water it contains) which will affect the amount of heat it can produce. If you purchase wood in Cords, ask your supplier for a weight.
