Horse God is also fire. Mount Sinai was covered with smoke, because the LORD descended on it in fire. Fire gives heat energy plus light. However, we can change fire in work more easily than light. Engineers build engines for that purpose.
Horsepower can measure the power of engines also.
The rest of it goes to heat - to warm exhausted gases, a vehicle's body and its surroundings. However, it should not be so with God. We understand that God built His forces from angels. They are full of His energy. Biblical witnesses are proving it, because they always saw God's angels, just coming from God the Father on our earth, clothed in white .
