Describe the environmental advantages and disadvantages of using hydroelectric power to generate electricity in the UK. (6 marker)

Hydropower is generally available as needed; engineers can control the flow of water through the turbines to produce electricity on demand.

Explanation:

Impact on Fish. To create a hydro plant, a running water source must be dammed.

Limited Plant Locations. While hydropower is renewable, there are limited places in the world that are suitable for plant construction.

Higher initial Costs.

Carbon and Methane Emissions.

Susceptible to Droughts.

Flood Risk.

explanation:

Hydroelectric power is energy created using the power and movement of flowing or falling water. It currently makes up only around 2.2% of Britain's total electricity supply, but has a long history in the country, having first been harnessed in 1878 to power the lights of Cragside country house in Northumberland. Globally, hydropower accounts for around 17% of all energy production, so should the UK rethink its approach to going green.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
