2. Thermoelectric generator - Wikipedia

   en.wikipedia.org/wiki/Thermoelectric_generator

   From cars the main source of energy is the exhaust gas. [32] Harvesting that heat energy using a thermoelectric generator can increase the fuel efficiency of the car. Thermoelectric generators have been investigated to replace the alternators in cars demonstrating a 3.45% reduction in fuel consumption. [33]

3. Home fuel cell - Wikipedia

   en.wikipedia.org/wiki/Home_fuel_cell

   Home fuel cell systems in homes could lessen reliance on public utilities, increase energy efficiency, and reduce US dependence on foreign energy imports. [16] This self-generation of energy in a distributed generation approach would secure and increase US power generating capacity, enabling unused electricity to be sent back to the grids ...

4. Magnetohydrodynamic generator - Wikipedia

   en.wikipedia.org/wiki/Magnetohydrodynamic_generator

   The hot exhaust gas from an MHD generator can heat the boilers of a steam power plant, increasing overall efficiency. Practical MHD generators were been developed for fossil fuels, but these were overtaken by less expensive combined cycles in which the exhaust of a gas turbine or molten carbonate fuel cell heats steam to power a steam turbine.

5. Gas-fired power plant - Wikipedia

   en.wikipedia.org/wiki/Gas-fired_power_plant

   In total, gas-fired power stations emit about 450 grams (1 lb) of CO 2 per kilowatt-hour of electricity generated. [8] [9] This is about half that of coal-fired power stations but much more than nuclear power plants and renewable energy. [8] Life-cycle emissions of gas-fired power stations may be impacted by methane emissions such as from gas ...

7. Microgeneration - Wikipedia

   en.wikipedia.org/wiki/Microgeneration

   A new wind energy technology is being developed that converts energy from wind energy vibrations to electricity. This energy, called Vibro-Wind technology, can use winds of less strength than normal wind turbines, and can be placed in almost any location. A prototype consisted of a panel mounted with oscillators made out of pieces of foam.
