Hydro power

Water that moves from one level to another can make a wheel spin. The waterwheel was by far our most important source of power for a long time — otherwise it was our own muscle power. It was used for example in mills, sawmills, mines and blast furnaces.

At the end of the 1800s, the water turbine began to be used to produce electricity for industries and dwellings. The water turbine reminds us very much of the waterwheel but is made of steel and spins faster. It drives a generator, which in turn produces electric energy. About half of all electrical power that is produced in Sweden comes from hydro power. In future researchers hope to also be able to use wave power and tidal hydro power.
