Question: how much power does biomass produce?
Answer: A kilogram of cut grass contains about 4 million joules, also known as megajoules (MJ). That's slightly more electricity than the kilowatt hour used in the energy retail market. And wood, the most commonly used biomass, contains around 15 MJ/kg. But if it's dried before it's burned, that's boosted to around 18 MJ/kg.
