ABSTRACT

Water power (hydro-electric stations) Where a natural and continuous flow of water is available (i.e. waterfalls, or fast-flowing rivers), its potential energy can be used to turn a waterwheel coupled to a generator. This method is obviously inexpensive due to the fact that no cost is involved in providing the propulsion. However, in the UK the number of sites available for such generation on any useful scale is limited, and such sites are usually to be found in mountainous areas such as Scotland and Wales.
