Sunlight is Earth's primary source of energy. The other significant source of Earth's energy is the store of fissionable materials generated by the cataclysmic death of other stars. These fissionable materials trapped in Earth's crust give rise to geothermal energy, which drives the volcanism on Earth and also makes it possible for humans to fuel nuclear reactors. The solar constant is the amount of power that the Sun deposits per unit area that is directly exposed to sunlight.
