The term “energy” is defined by physicists as “the ability to do work.” The laws of physics tell us that energy can neither be created nor destroyed, but only transformed from one form to another. In practical terms, Earth gets most of its energy from the Sun. The Sun is a large natural fusion energy source, sending its light and heat (forms of energy) into the surrounding solar system and into the universe beyond. Most stars are engaged in a similar process. The energy impinging on the Earth from the Sun is captured and stored in many ways but most importantly in living organisms. The Earth’s extensive fossil fuel resources are the result of transformation and storage of the energy of living animals and plants over billions of years. Energy is also released from currently living organisms, most often by burning wood, but also by chemically transforming crops and other organic matter into burnable fuels.
