Introduction video
Hydro-electricity is the most widely used form of renewable energy (16% of global electricity generation)
Based on 2 things:1. The difference in heigth2. The flow of water
What?
Water Turbine Generator
What?
Electricity
Hydro-electricity = 99% 200 power plants More than 800 small river plants
In Norway
3 power plants 6 small river plants
In Sykkylven
Power plant + Water plant = unique By going through the power plant, the water
loses his very strong pressure. So it can go through a water plant too. (otherwise the pressure would be to high)
In Sykkylven
Several small river plants in Walloon No big power plants because we don’t
have the difference in height
In Belgium
CleanRenewableNo CO2 pollution
Pro’s
Impact on the local communityPlants are destroyed in the area
where it is built
Contra’s
Windmills Wave energy Thermal energy
Other ways in Norway

Pro`s
No pollution Reduced dependence Job prospects/opportunities Cheap energy
Contra`sImpact on the environment Impact on the landscape Annoying sounds Shadow pollution

Windmills Solar panels
Other ways in Belgium
A lot in Belgium, few in Norway The light of the sun is transformed into
energy
Solar panels
Pro`s
No pollution Reduced dependence Job prospects Cheap energy
Contra`s
It’s ugly It needs a lot of cleaning
When we came to Norway we noticed that Norwegians don’t switch off the lights as quickly as we do in Belgium.That’s because energy is cheaper in Norway than in Belgium.So we can conclude that hydro-electricity is very important in Norway.
Save energy?
