1. Nuclear Energy:

    • Uranium or plutonium atoms are split in a reactor to release heat.
    • Heat generates steam, which drives a turbine connected to a generator, producing electricity.
  2. Solar Energy:

    • Photovoltaic (PV) Cells: Sunlight hits PV cells, generating electric current through semiconductor materials.
    • Solar Thermal: Mirrors focus sunlight to heat fluid, producing steam that drives a turbine to generate electricity.
  3. Wind Energy:

    • Wind turns turbine blades connected to a generator.
    • The rotation of the blades generates mechanical energy, which is converted into electricity.
  4. Hydroelectric Energy:

    • Flowing or falling water (often from a dam) spins a turbine.
    • The turbine powers a generator, converting kinetic energy of water into electricity.
  5. Tidal Energy:

    • Tidal Stream: Moving tides turn underwater turbines, generating electricity.
    • Tidal Barrage: Water flows in and out of a dam-like structure, driving turbines as tides rise and fall.
  6. Wave Energy:

    • Wave motion moves floating or submerged devices, driving pistons or turbines.
    • This movement generates electricity, often converted directly or stored in batteries.
  7. Geothermal Energy:

    • Heat from underground reservoirs heats water, producing steam.
    • Steam drives a turbine connected to a generator to produce electricity.
  8. Biomass and Bioenergy:

    • Direct Combustion: Biomass is burned to produce heat, which can generate steam for turbines.
    • Biochemical Conversion: Microorganisms break down organic material, producing biogas (methane) for combustion.
    • Thermochemical Conversion: Biomass is gasified or pyrolyzed to create biofuels for combustion or refining.
  9. Fossil Fuels (Coal, Oil, Natural Gas):

    • Combustion: Fuels are burned to produce heat, creating steam.
    • Steam drives turbines connected to generators, producing electricity.
  10. Battery Energy Storage:

  • Charge: Electric current flows into the battery, storing energy in chemical bonds.
  • Discharge: The process reverses, releasing stored energy as electric current.
