Water energy

Questions How does a water energy plant function? How does it effect: ◦ wildlife ◦Nature Difference in Norwegian and German energy forms? Why water energies is more lucrative in norway then in german?

water energy plant Reservoir Dam ◦differnt types ◦Depends on water mass Intake ◦Water flow control ◦Filtering higher velocity ◦Because of  Water Pressure  Water mass Turbine ◦Rotating engine ◦(Francis, Kaplan etc.) Generator ◦”Makes” the water energy to electricity Transformers ◦Altern the electricity Outflows ◦Water flow control

Disadvantages with water energy Fish ◦Disrupts  breeding  Living conditions River animals ◦Disrupts  Food resources  Breeding  Survivial condition Vegetation ◦Disrupts  Nutricion  Spreading  Over flow Damming

Advantages with water energy No carbondioxide release It’s renewable There are a large amount of water Always available can store the water No production cost

Reasons Mountains ◦Needs less daming ◦Higher drop Lakes ◦Much water Waterfall ◦High speed ◦Much energy Experience ◦Technology Rivers

Differences Norways main energy source is pure water energy

Possibility for water energy

Other water energy types Tidal EnergyWave energy use energy from the movements under water Use the energy on the water surface
