What is Hydro Power?

Hydropower is energy that is derived from moving force of water which is used to generate electricity. This form of power generation has been used for centuries in the form of waterwheels and mills alongside rivers. Hydroelectricity is created using conventional hydroelectric methods such as dams. Hydro dams use the energy flow of the dammed water to drive a water turbine and generator in order to create electricity. Run-of-river hydroelectricity is produced by using the water running downstream to generate power as it passes the dam. Tidal power is also a form of hydro power that makes use of the rise and fall of the ocean to produce energy. Hydropower is a renewable source of energy that emits no pollutants or greenhouse gases. Hydropower, can however, have its setbacks, as damming rivers can permanently alter the surrounding eco-systems and habitats. However dams can offer flood control and regulation of water supply. Hydropower is the most cost efficient method of electricity generation in currently in existence. In Canada, 75% of all electricity is generated in British Columbia, Manitoba and Quebec is generated through hydroelectricity.
