What is the energy input of wood burning?

The energy input of wood burning refers to the amount of energy released during the combustion of wood, primarily measured in British thermal units (BTUs) or megajoules (MJ). This energy results from the chemical reaction between wood and oxygen, producing heat, light, water vapor, and carbon dioxide. The energy content of wood varies based on its species, moisture content, and density, with seasoned hardwoods generally providing more energy than softwoods. On average, seasoned wood can yield around 4,000 to 8,000 BTUs per pound.
