Hydro power energy Hydropower is the renewable energy contained in flowing water. Electricity generated using hydropower is known as hydroelectricity and is generally considered to be reliable. There are three main methods for generating hydroelectricity: Storage – where a dam collects water in a reservoir, then releases it to drive turbines, producing electricity Pumped storage – where water is pumped to a higher reservoir, usually during times of low-priced electricity, then released to a lower reservoir, again driving a turbine, usually when the electricity price is higher Run-of-river – where the natural flow of a river or stream is used to drive a turbine. How electricity is generated through hydropower In order to generate electricity from the kinetic energy in moving water, the water has to move with sufficient speed and volume to spin a propeller-like device called a turbine, which in turn rotates a generator to generate electricity. Roughly speaking, one gallon of water per second falling one hundred feet can generate one kilowatt of electricity. To increase the volume of moving water, impoundments or dams are used to collect the water. An opening in the dam uses gravity to drop water down a pipe called a penstock. The moving water causes the turbine to spin, which causes magnets inside a generator to rotate and create electricity. There are a variety of types of turbines used at hydropower facilities, and their use depends on the amount of hydraulic head (verticalShow MoreRelatedA Brief Note On Hydro Quebec And The Largest Electricity Company1630 Words   |  7 PagesWhat is Hydro-Quebec?

Hydropower as a source of electricity is a feasible low carbon alternative, as dams and reservoirs have low greenhouse gas and air pollutant emissions compared to fossil fuel energy generation. Canada has harnessed this potential power sourceRead MoreEnergy: What is Micro Hydro Power1098 Words   |  4 PagesMicro hydro power is a concept that has over the years been adopted as an alternative energy supply for communities whose access to a national grid is limited by a factor or two. In fact, hydro power is one of the oldest sources of energy used by the human civilization. It has been used for hundreds of years to turn waterwheels for the purpose of sawing logs, grinding grains, and the manufacture of cloths. From the last century, large scale hydro power plants have been used mai nly for the generationRead MoreHydropower is taking the energy out of water flowing from a higher elevation to a lower one and700 Words   |  3 PagesHydropower is taking the energy out of water flowing from a higher elevation to a lower one and converting it into electricity.
