Energy accounting is like a budget for energy. To keep track of how much energy (electricity, gas, oil, etc.) is being used, we need to keep track of the "in" and "out" of the energy used. In energy accounting, we record how much energy is used for different activities. We also record how much energy is saved or used to generate renewable energy. This helps us see how much energy we are using and how we can use less. It helps us find ways to be more energy-efficient and also helps us figure out how much money we need to pay for the energy we use.
