electric energy: electric light can be converted into light energy

thermal energy: internal energy can be converted into heat energy when cooking in a stove

mechanical energy: electric motor can be converted into mechanical energy

chemical energy: dry battery can be converted into electric energy. Nuclear power plant

hydropower: hydroelectric power can be converted into electric energy

wind power can be converted into electric energy

magnetic energy, and electromagnet can be used to convert magnetic energy into mechanical energy, and compass < p It is converted into mechanical energy or electric energy by fan.

water energy: the potential energy formed due to different water heights is converted into mechanical energy or electrical energy by a hydraulic turbine.

heat energy: it is caused by the movement or vibration of a large number of molecules in a substance and is related to temperature. Generally, heat energy needs to be converted into mechanical energy: working medium, high-temperature heat source, low-temperature heat source, conversion equipment, commonly used internal combustion engines, steam turbines, gas turbines, etc., commonly used cycles: Rankine cycle, Carnot cycle ...

Chemical energy: energy is released through chemical reactions: combustion is the most common and widely used, such as the combustion of coal and oil. Two kinds of common conversion: the primary battery is converted into electric energy, the heat energy is generated by combustion, and then it is converted into mechanical energy by a heat engine.

solar energy: the photoelectric effect generates current, and the irradiated object generates heat energy (radiation heat exchange).

kinetic energy: the energy produced by the macroscopic movement of a mass object or the energy possessed by the movement of tiny particles, the former is mechanical energy, and the latter is the cause of heat energy. High-quality energy forms can be completely converted into any other forms of energy.

mechanical energy: the sum of kinetic energy and potential energy. The highest quality energy type can be completely converted into any other form of energy.

energy conversion equipment: turbine machinery, internal combustion engines, steam engines, water turbines, fans and so on. .....
