Changing landscapes - hydroelectricity
Exploring hydroelectricity plants in Snowdon, North Wales. A hydroelectricity plant is used to generate power from fast-flowing water. The steep slopes of Snowdon help the mountain streams to flow into the lakes below. The water is channelled from the lakes into large pipes. The fast-flowing water from the pipes travels down the mountain and passes through a turbine. The water turns the turbine and this generates electricity.
