Energy production

Energy production


Sun
 Photovoltaics - Solar cells. Solar panels
Photovoltaics convert light into electricity using semiconducting materials that perform the photovoltaic effect.
Types of solar cells:
  Black silicon
   Achievements up to 22 percent efficiency
  Perovskite solar cell
   Up to 22 percent efficiency
  Monocrystalline silicon
   Around 15 percent efficiency
  Polycrystalline silicon
  Amorphous silicon
  Thick film and thin film
  And more
New photovoltaic technology:
 Tandem and multi junction solar cells
 With each layer having its own efficiencies due to the wavelengths of light

Wind
 Wind Energy
  Normal
  And axis

Water stream dynamo's and dams (hydroelectricity)
Tidal power plants and sea wave energy


Sunlight reflection
 And turning water into steam to drive a turbine

Biomass


Laser powerplant
 Produces energy by colliding laser beams.

Nuclear fusion


Geothermal power plants
 Thre three basic types of geothermal power plants are:
 Dry steam, flash steam and binary cycle.


Nuclear powerplants
 Atom splitting of for example uranium or plutonium. Nuclear fission

Thorium reactors


Thermal power plants
 Fossile fuels
  Coals, gas and petrolium.
