  2. Thermoelectric generator - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_generator

    Thermoelectric materials generate power directly from the heat by converting temperature differences into electric voltage. These materials must have both high electrical conductivity (σ) and low thermal conductivity (κ) to be good thermoelectric materials. Having low thermal conductivity ensures that when one side is made hot, the other side ...

  3. Thermoelectric effect - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_effect

    When an electric current is passed through a circuit of a thermocouple, heat is generated at one junction and absorbed at the other junction. This is known as the Peltier effect : the presence of heating or cooling at an electrified junction of two different conductors.

  4. Cogeneration - Wikipedia

    en.wikipedia.org/wiki/Cogeneration

    Cogeneration or combined heat and power (CHP) is the use of a heat engine [1] or power station to generate electricity and useful heat at the same time. Cogeneration is a more efficient use of fuel or heat, because otherwise- wasted heat from electricity generation is put to some productive use.

  5. Thermoelectric materials - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_materials

    Cogeneration power plants use the heat produced during electricity generation for alternative purposes; being this more profitable in industries with high amounts of waste energy. [135] Thermoelectrics may find applications in such systems or in solar thermal energy generation. [135] [139]

  6. Solar updraft tower - Wikipedia

    en.wikipedia.org/wiki/Solar_updraft_tower

    The solar updraft tower (SUT) is a design concept for a renewable-energy power plant for generating electricity from low temperature solar heat. Sunshine heats the air beneath a very wide greenhouse-like roofed collector structure surrounding the central base of a very tall chimney tower.

  7. Electricity generation - Wikipedia

    en.wikipedia.org/wiki/Electricity_generation

    Electricity generation is the process of generating electric power from sources of primary energy. For utilities in the electric power industry , it is the stage prior to its delivery ( transmission , distribution , etc.) to end users or its storage , using for example, the pumped-storage method.

  8. Sources of electrical energy - Wikipedia

    en.wikipedia.org/wiki/Sources_of_electrical_energy

    Heat: Energy produced by heating the junction where two unlike metals are joined. Light: Energy produced by light being absorbed by photoelectric cells, or solar power. Chemical: Energy produced by chemical reaction in a voltaic cell, such as an electric battery. Pressure: Energy produced by compressing or decompressing specific crystals.

  9. Thermal power station - Wikipedia

    en.wikipedia.org/wiki/Thermal_power_station

    A thermal power station, also known as a thermal power plant, is a type of power station in which the heat energy generated from various fuel sources (e.g., coal, natural gas, nuclear fuel, etc.) is converted to electrical energy. [1] The heat from the source is converted into mechanical energy using a thermodynamic power cycle (such as a ...
