Hydropower

This lecture is devoted to the hydropower – the power derived from the energy of falling water or fast running water, which may be harnessed for useful purposes. Since ancient times, hydropower from many kinds of watermills has been used as a renewable energy source for irrigation and the operation of various mechanical devices, such as gristmills, sawmills, textile mills, trip hammers, dock cranes, domestic lifts, and many more. We will discuss in details hydroelectricity production as this energy source plays a key role in Iceland.
