Kaya identity

Kaya identity refers to how much energy is used in a country or a person's daily life. Imagine you have a toy car and you need to make it go. You can use a battery and change it often, or you can use a bigger battery that will last a longer time. The same is true for countries or people. They can use more energy or less energy to do the same things.

The amount of energy used is important because using too much energy can have negative effects on the environment. Just like how leaving the lights on for too long can waste energy and make your electricity bill higher.

To calculate kaya identity, we look at several things like how much energy is used for transportation (like cars and planes), how much energy is used for heating and cooling buildings, and how much energy is used for making products. This helps us understand how much energy is being used and where we can make changes to use less energy and be more eco-friendly.

In summary, kaya identity measures how much energy is used in a country or person's daily life and it helps us find ways to use less energy and be more eco-friendly.
