Calorific value

Calorific value refers to the amount of energy released when a fuel is burned completely. It indicates how much heat or energy a substance can produce, usually measured in units like calories or joules. Think of it as the fuel's "energy content"—the higher the calorific value, the more energy you get from burning that material. This concept helps determine the efficiency and usefulness of fuels such as coal, wood, or natural gas for cooking, heating, or generating electricity. It's an essential factor in comparing different fuels for energy production.
