Hydro Power

Hydro Power

IrrigationIrrigation means its something artificial application of water to the land or soil.How does Hydro power work?Flowing water from a high level will flow into a pipe called the penstalk which carries the water down to a turbine water wheel. The water pressure increases while it goes down the pipe, and the pressure powers the turbine connected to the a generator. Inside the generator is a router that is spun by the turbine. As the turbine spins the generated energy is turned into electricity and transferred to the power lines. The electricity goes to the generator. Once the electricity is generated it is mixed with all of the other power grid.What it is use for?Hydro power is use for irrigation and the operation of many mechanical devices such as watermills, cranes and sawmills. It is generated of electricity by the push/pull of the water. It generates it by 3 different ways: Tidal power, Wave power and Hydroelectric powerIt is also use for flood control and for navigation.

How does hydro power worksBenefits of having hydro powerThe benefits of having hydro power is Dams are designed to last many decades and so can contribute to the generation of electricity for many years / decades.How much Hydro Power CostsHydro power is very expensive.It depends on the place it was produced (created).To build a dam would cost 250 mill to 1.25bill.Advantages and disadvantages that Hydro power haveAdvantages1.If electricity is not needed, the sluice (its like a slide that takes out rocks from rivers) can be shut and stop the electricity generation. The water can be saved for another time when electricity charge is high.2.Dams can be last for decades and can assign electricity for many years.3. When it is use, electricity by dam systems do not harvest green house gases.4.Once a dam is created electricity can produced at a constant rate. (it means a amount of a number or more than one amount of numbers)5. A lake that forms behind the dam can be used for water sports and other activities in the water. Large ones become tourist attractions.DisadvantagesDams are expensivePeople living in towns and villages that is in a valley has to move out because of flood. they lost their farms and their lands.If a dam breaks, many people would probably die. It happened before in The U.S because of a heavy rainfall.

4. hydropower dams can disturb the natural flow of rivers which can have negative impact on many river ecosystems5. If really large hydropower dams are built, it can lead to earth quakes, erosion, landslides and serious geological damage.Reliability Hydro power is more reliable than any other forms of electricity. Why?Because the water will keep flowing down hill, as long as the water never dries out, they will always create electricity.You will never run out of gas or uranium or coal to power the plant.How much of Canadas energy comes from hydropower?Canada is the worlds second highest producer of hydroelectricity in the world after China.It is one of few countries to generate the majority of its electricity from hydroelectricity (59% in 2006). In 2007, Canada produced 368.2 terawatt-hours of electricity using hydroelectric dams,11.7%.Some provinces and territories, such as British Columbia, Manitoba, Newfoundland and Labrador, Quebec and Yukon, produce over 90% of their electricity in Canada

Thank youI hope you learn a lot about hydro power.Bye
