Energy.

In physics, energy is a measure of the material that must be transferred to an object in order to perform a function, or to heat an object. Power is a stored value; energy conservation law states that energy can be transformed into form, but can be created or destroyed. The SI unit of power is the joule, which is the energy transferred to an object by the function of moving it a distance of 1 meter compared to the power of 1 newton.

The Sun is the source of energy for many life on earth. It derives its energy primarily from nuclear fusion in its core, converting it into energy as the protons combined form helium. This energy is then transferred to the sun and released into space, especially in the form of light (simple) energy.

Typical forms of energy include kinetic energy of a moving object, potential energy in the position of an object in the energy field (gravity, electricity or magnet), elastic energy is stored by stretching solids, chemical energy released when fuel is burning, light energy is held by light, and thermal energy because of the temperature of the object.

Mass and power are closely related.

Living organisms need energy to survive, just as humans do from food. Human civilization needs energy to operate, found in energy resources such as fossil fuels, nuclear fuel, or renewable energy. Earth's ecological processes are driven by the radiant energy that the Earth receives from the Sun and the earth's warming energy contained in the earth.
