Energy content
A common hardwood, red oak, has an energy content of 14.89 megajoules per kilogram (6,388 BTU per pound), and 10.423 megajoules recoverable if burned at 70% efficiency.[2]
The Sustainable Energy Development Office (SEDO), part of the Government of Western Australia states that the energy content of wood is 16.2 megajoules per kilogram (4.5 kWh/kg).[3]
According to The Bioenergy Knowledge Centre, the energy content of wood is much more dependent on the moisture content than the species. The energy content (number of joules of heat produced) improves towards the total number of joules stored in the wood as it dries. [4]
