Geothermal energy is applied by using heat created within the Earth to power turbines typically by pumping water into a heated pocket of the Earth creating steam emissions to spin turbines similar to a natural geyser.
Kinetic energy is the energy created by an object in motion. It is defined as the amount of energy required to take an object not in motion to a given velocity. Gravity is often a factor in the analysis of kinetic energy on Earth and throughout the Universe.
Magnetic energy is a common but often unnoticed force which affects the daily lives of all life on Earth. Without polar magnetism our planet would be bombarded with solar radiation making it impossible for the myriad complex living organisms to thrive.
Nuclear energy or nuclear fusion is a result of the scientific developments from the arms race of World War II and essentially equates to creating a sun like phenomenons to produce heat which evaporates water into vapors to power turbines.
Electricity is the backbone of our power infrastructure system and almost all forms of energy production used currently are designed with the intention of creating electricity through various means to power our growing world.
Fossil fuels are created through anaerobic decomposition from the tissues of dead living organisms which have been buried for an extended period of time. Typically these are created from microorganisms or plant life and contain high amounts of carbon.
