As the matter on the earth has energy that it get so the various inputs like the solar and tidal and the geothermal factors. As recycling is part and parcel of the earth and each and every day the attr is recycle and processes and thus create an abundance of energy that again is available in the 24 hour format.
The law of energy states that energy can transform itself but is never destroyed hence the ,matter is recycled so is the energy that is needed to transport the matter and recycle the contents and thus the earth produces this energy in tidal tectonic and glacial movement and same.
Thus this phenomenon also take place in the form of a crustal recycling and the energy thus is recyclied along with it and becomes available in the next day.
