How does the law of conservation of energy impact the amount of energy that is available on our planet?

The Law of Conservation of Energy impacts the amount of energy that is available on our planet because energy can not be created or destroyed, but it can be transformed into different categories of itself. Generally saying that the creation of energy is impossible, being that energy is itself until it gets transformed into a different category. Energy under that category can run out, therefore, more energy must be transformed into that category to replace the energy that was already yet consumed.
