How power is produced?
It is produced by hydroelectric dams. In these dams, falling water (water in motion) is used to turn turbines which rotate the alternator - the machine that generates the electricity.

How is hydro electricity connected to renewable energy?
Provided water was available in dams, hydro electricity can be produced indefinitely.
Why do Pakistan need dams?
Well ! Pakistan has been facing energy crises for the past 4 years. The electricity produced there does't fulfil the needs. So, they need to build more dams to create more electricity to meet the needs of the population.
What are the advantages and disadvantages of hydel power?
Advantages:It helps in generating electricity for the people .Construction of dams helps in this process.Once dams are constructed electricity can be produced at a constant rate.Dams are designed to last many decades and can contribute the generation of electricity for many years.When in use the electricity produced by dams do not produce green house gases.this helps in pollution free environment. Disadvantages:the release of water from dams during heavy rains can cause floods.Regulating and damming of rivers affect the natural flow of water causing the sediments to settle at the bottom resulting in rockier stream beds.It also fragment the rivers making it difficult for the aquatic fauna to migrate especially for spawning.Also construction of dams are highly expensive.
What is hydroelectrity?
When water (Hydro) falls down through the turbine blades of an electricity generator, the blades are made to spin. The blades are connected to a shaft, which is connected at the upper end to the armature of a large generator, which produces electricity. Most, if not all, hydroelectricity is produced in tall dams on rivers. Examples include Hoover Dam in Nevada, and Grand Coulee Dam in Washington. The electricity produced in dams is no different from electricity produced in other ways.
Where you get your electricity from and how your electricity is produced?
your electricity in your home comes from wires under ground or on power lines. it comes from the power company that gets it from wind, solar, nuclear, hydroelectic dams, or from burning coal.
What is water mainly used for in nz?
electricity dams/hydro dams
Where is hydroelectric energy produced in the world?
Pretty much anywhere where there are decent sized rivers, a need for electricity, and enough money to build the dams.
What dams percentage of electricity is produce in Pakistan?
Dams produce 34 percent of electricity in Pakistan...so my school says :).
