  • How does hydro-electric power (HEP) work?
  • How important is it for the UK?
  • Advantages & Disadvantages of hydro-electric power:
  • Hydro-electric power is large-scale dams or smaller micro-dams, which create a head of that spins turbines to generate electricity. There are two ways of using the energy in the flowing water to produce electricity, these are: hydroelectric dams or pumped storage. The hydroelectric dams trap the flowing water, then release it again but under great pressure. And the pumped storage is not really a renewable energy, but it is a way of storing energy.
  • The importance of hydro-electric power in the is that the large dams are expensive.Micro-dams are becoming popular options at the local level. In 2016, HEP supplied just 1.4% of the UK's electricity production. And in 2017, they supplied 1.8% of the Britain's total electricity supply. And also, 18% of their renewable energy. This is the 4th most-generated renewable energy source after:wind power, tidal power, and solar power.
  • Advantages of hydro-electric power:Advantages of hydro-electric power is that there is: no waste or pollution is produced, and electricity can be generated constantly.Disadvantages of hydro-electric power: Disadvantages of hydro-electric power is that: dams are very expensive to build, and suitable sites for large-scale projects are very hard to find.
