What innovation had the effect of producing electricity and improving farming?
A Dam
What does hydro electricty mean?
Hydroelectricity is generated by huge amount of water pouring through electric turbines in a water dam. Great Coulee Dam, Hoover Dam, and Lower Granite Dam are some that I can think of.
How do dams help produce hydroelectric energy?
Dams produce electrical energy by utilizing the energy in the water stored in an elevated lake. Outlets in the dam allow water to escape down a pipe, trading potential energy for kinetic energy, ie, as it falls it moves faster. At the bottom of the dam, the fast moving stream of water enters a turbine where the it hits the blades of the turbine and makes it spin rapidly. The spinning turbine is connected to a generator, a rotating machine with magnets that converts the energy of rotation into electrical energy, usually AC. The AC voltage is run into a transformer to convert it to high voltage (higher voltage is better for long distances) and sent on towers to where it is needed.
What is the largest hydroelectric project?
Hoover Dam is the largest hydro electric dam in the world. This Is Totally Wrong. The Largest Hydro-Electric Dam In North America Is The Mighty Grand Coulee Dam In The State Of Washington Which Produces 3 Times The Megawatts As Hoover Dam. Grand Coulee Produces 6,809 megawatts And Hoover Dam Only 2,078 megawatts. The Mighty Grand Coulee Contains Nearly 12 Million Cubic Yars Of Concrete And Hoover Only 3,250,000 Cubic Yards. Grand Coulee Dam Contains In It's Third Powerhouse 3 Of The Worlds Largest Generators At 805 Megawatts Each. The Mighty Columbia River Flows 3 Times The Water As Does The Colorado. These Two Dams Are Not Even Close In Comparison.
How many kilowatts a hour does a dam produce?
Most power plants produce several Megawatts of power. A Megawatt is one million watts.
Can water produce electricity?
yes in a hydro dam
How many watts of electricity does a hydro electric dam produce?
a lot
What is a hydro electric generator?
Hydro- means water. A hydro-electric generator uses moving water from a river or dam to turn the generator and produce electricity.
What dam creates a large amount of hydro electricity in Zambia?
The Kariba Dam creates most of the electricity in central Africa.
Is dams built on rivers to produce electricity?
Because you need running water to spin the turbines to create electricity in a hydro plant.
How does hydro-power form?
Hydro-power is electricity created when water is forced by gravity from a dam and through turbines. The spinning turbines turn generators, and electricity is produced.
What is the purpose of a hydro electric dam?
to generate electricity by utilizing energy of falling water
How do tunnels in dams produce electricity?
The tunnels in the dam (what you see on the "low side" of the dam) dont produce electricity. These are the 'outflow' channels for water that is exiting a turbine (which is what generates the electricity). The weight of water behind the dam forces it down a tunnel to a turbine where the water pressure spins the turbine, which generates electricity. The water, once it passes through the generator, goes out a tunnel to a river below the dam. This is typically the water you see coming out from under a "hydro-electric" dam. There are also spillways to let excess water out from the reservoir (high side) behind the dam if the water gets too high.
How reliable is hydro electricity?
As long as the rain keeps falling in the catchment area, hydro electricity is very reliable. It will run day and night if required, as the water is stored up behind the dam. If the rainfall is unreliable, then hydro electricity is unreliable too.
What type of structure is three gorges dam?
The Three Gorges Dams were made of concrete.
Canada has a number of hydroelectric plants what is a hydroelectric plants what does the prefix hydr or hydro mean?
Hydro means 'fluid' and Hydro-electric means electricity derived from devices driven by fluid. IE a hydro-electric power plant uses the power of water channeled from a dam to drive water turbines which in turn drive the generators that produce the electricity.
Where is a good place to built a hydro electricity dam?
Anywhere on a river where there is a quick moving current.
