Band 5+: The diagram shows the production of hydro-electricity. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The diagram illustrates how a production of hydro-electricity works.

Overall, the process includes many tubes going from the reservoir yet, the entire production does not only rely on them. Moreover, the powerhouse contains another instrument called a generator.

Firstly, the water gets sucked in by a penstock that is directly connected to a reservoir in order to spin a turbine. Furthermore, the H2O goes through a turbine, which starts spinning thanks to the force of the current, and gets discarded under the long distance power lines.

In continuation, the spinning tool down the generator powers the entire powerhouse due to the important force of the pushed water so, it generates electricity that goes straight into the long distance power lines. A noticeable element of this chart is the level of each component of the production of hydro-electricity. Furthermore, some of the elements are under the surface like the penstock and the turbine, while others, such as the generator and the lines, lie on top of it.
