  2. Energy - Wikipedia

    en.wikipedia.org/wiki/Energy

    equal amount of energy carried by matter that is moving from one system to another. A turbo generator transforms the energy of pressurized steam into electrical energy. Energy may be transformed between different forms at various efficiencies. Items that transform between these forms are called transducers.

  3. Joule - Wikipedia

    en.wikipedia.org/wiki/Joule

    A human in a sprint has approximately 3 kJ of kinetic energy, [20] while a cheetah in a 122 km/h (76 mph) sprint has approximately 20 kJ. [21] One watt-hour, of electricity or any other form of energy, is 3.6 kJ. Megajoule The megajoule is approximately the kinetic energy of a one megagram (tonne) vehicle moving at 161 km/h (100 mph).

  4. Energy transformation - Wikipedia

    en.wikipedia.org/wiki/Energy_transformation

    Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. [1] In physics, energy is a quantity that provides the capacity to perform work or moving (e.g. lifting an object) or provides heat. In addition to being converted, according to the law of conservation of energy, energy is ...

    e. Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Common phenomena are related to electricity, including lightning, static electricity ...

    Gray (unit) – (symbol: Gy), is the SI unit of energy for the absorbed dose of radiation. One gray is the absorption of one joule of radiation energy by one kilogram of matter. One gray equals 100 rad, an older unit. Heat. Mass–energy equivalence – where mass has an energy equivalence, and energy has a mass equivalence.

  7. Renewable energy - Wikipedia

    en.wikipedia.org/wiki/Renewable_energy

    Renewable energy (or green energy) is energy from renewable natural resources that are replenished on a human timescale. The most widely used renewable energy types are solar energy, wind power, and hydropower. Bioenergy and geothermal power are also significant in some countries. Some also consider nuclear power a renewable power source ...

    Wind farm is a group of wind turbines in the same location used for production of electric power. Wind power is the conversion of wind energy into useful form, such as electricity, using wind turbines. An electrical grid is an interconnected network for delivering electricity from generation facilities such as wind farms to consumers.

  9. Primary energy - Wikipedia

    en.wikipedia.org/wiki/Primary_energy

    Primary energy (PE) is the energy found in nature that has not been subjected to any human engineered conversion process. It encompasses energy contained in raw fuels and other forms of energy, including waste, received as input to a system. Primary energy can be non-renewable or renewable. Total primary energy supply (TPES) is the sum of ...
