Energy Production in Sweden

Hydropower Plant

  • About 45% av Swedens energy is produced by Hydro Power Plant
  • We have like 2000 hydro power plats in Sweden. 200 of these are quite big and their effect is 10 MW or even more.

Hydropower Plant

How does it work?

  • The rain gathers in big reservoir.
  • The water flows from a higher to a lower level passing a turbine that starts rotating. The kinetic energy from the water is converted into machanical energy.
  • The turbin is connected to a generator by shafts and gears. When the turbine spins, the generator spins as well and converts the mechanical energy from the turbine into electric energy.
  • Transmission lines conduct electricity from the hydropower plant to our homes.

Nuclear Power Plant

  • 40% av Swedens energy is produced by Nuclear Power Plant
  • Currently we have 8 active ractors in Sweden, placed in 3 locations: Ringhals, Forsmark and Oscarshamn

Nuclear Power Plant

How does it work?

  • Uraniun athoms split in the reactor, causeing the water to boil. The steam is leded to the turbin.
  • As the steam blows past the turbine's vanes, they spin around at high speed. The heat energy from the water converts into mechanical energy.
  • The turbin is connected to a generator by shafts and gears. When the turbine spins, the generator spins as well and converts the mechanical energy from the turbine into electric energy.
  • Transmission lines conduct electricity from the hydropower plant to our homes.

Wind Power Plant

  • About 10% av Swedens energy is produced by Wind Power Plant. It gets bigger and bigger every year,
  • The biggest wind power plant is called Lillgrund and it started 2008.
