Water is stored at a height behind the dam. It is then allowed to fall through special channels in the dam, gathering speed as it goes (the potential energy being turned into kinetic). Near the bottom it goes through several turbines, which turn large magnets inside coils of wire (turning the kinetic energy into electrical) and the water is then allowed to continue its flow through the river.
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.
No
electricity from water is called hydro - or hydroelectric power
Steam is used to spin a turbine, which then generates electricity.
Coal power stations burn coal to heat water to produce steam, which is then used to spin electricity turbines to generate electricity. The burning coal releases carbon dioxide.Wind farms have blades which turn in the wind to spin electricity turbines to generate electricity. There are no harmful carbon dioxide emissions.
Moving water can be used to generate electricity in hydroelectric power stations.
There are nine hydroelectric power stations that generate electricity on the Waikato River. They were constructed between 1929 and 1971.

Yes
No
They both generate electricity.
Yes most power stations do use heat to generate electricity. Heat energy of the fuel (e.g. burning coal, burning oil, nuclear fission) is utilized to heat water present in the boiler. This heating generates steam, which is then utilized to run the turbine. However some power stations get the energy to generate electricity without using heat (e.g. hydroelectric dams, wind power, sea wave power, solar cell generation systems).
Singapore does not use hydroelectric dams to generate electricity.
Singapore does not use hydroelectric dams to generate electricity.
In hydroelectric power station we use the potential energy of water to generate electricity.
Whether the electricity is generated by conventional power stations, or hydroelectric power generation, the electricity used in homes and businesses will still be the same, and used the same.
