Because in a drought there is not enough water to drive the turbines. So no electricity is generated.
There are around 2,000 hydroelectric power stations in Britain. These power stations generate renewable energy by using the flow of water in rivers and streams to turn turbines and produce electricity.
because the conditions for a hydroelectric power stations in the uk aren't right so only a few can be built.
Hydroelectric power stations certainly have their advantages and disadvantages, as do all forms of electrical generation. Probably the best solution is to use a combination of different means of producing electricity, with hydroelectric stations as part of the mix.
A power station that harnesses power from running water.
The three main types of power stations are thermal power stations, hydroelectric power stations, and nuclear power stations. Thermal power stations generate electricity by burning fossil fuels, while hydroelectric power stations harness the energy of flowing water. Nuclear power stations utilize nuclear fission to produce heat, which is then converted into electricity. Each type has its own advantages and environmental considerations.
Moving water can be used to generate electricity in hydroelectric power stations.
Hydroelectric power is a great way to keep our environment clean. Unlike gasoline, hydroelectric power combusts to form water as a byproduct which does not harm earth.
No, they can't, they have to be powered up and down over several hours - especially nuclear power stations. This is why hydroelectric power stations are so useful to deal with surges in power demand, they can go from zero to full in seconds - Dinorwig Hydroelectric powerstation is the fastest, taking 12 seconds to go from 0 - 1,320 mw.
Tidal power stations require specialized technology to capture energy from changing tides, which is still in the early stages of development and more expensive to build and maintain compared to traditional hydroelectric power stations. Additionally, tidal power stations face more technical challenges due to the harsh marine environment, increasing their construction and operation costs.
for the passage of flood discharge
i don't now so haaaaaaaaaaaaaaaa
Hydroelectric power plants or H.E.P stations use a flowing river to turn a turbine which powers the genertator much like other power sources to create electricity. The water is then returned to the river. H.E.P stations can also be in a reservoir.
