Heat
All of the energy on Earth we receive is from the Sun. From there, energy is passed on through different forms but is never destroyed. From the sun, energy is transferred to the soil, then from the soil to the plants, then from the plants to the animals, then from the animals to our food, and from our food to us. The energy we get is transferred to us so we can set the mousetrap, and then the energy is transferred to the mousetrap by accelerating, and then the energy is transferred to friction through the wheels, which is then transferred to thermal energy, and then becomes heat. The heat radiates off of the Earth and the cycle continues.
