1,373 Questions
Why has hydroelectric power come under criticism recently?
The environmental consequences are quite high.
Do hydro electric power plants make a lot of noise?
If you stand next to a turbine or generator yes. Overall very little.
Can you put the word hydroelectric in a sentence?
In hydroelectric power station we use the potential energy of water to generate electricity.
What is Selection criteria for site for hydro power plant?
While selecting a suitable site for a hydro-electric power plant, if a good system of natural storage-lakes at high altitudes and with large catchment areas can be located, the plant will be comparatively economical.
Anyhow the essential characteristics of a good site are:
- large catchment area,
- high average rain fall and
- a favorable place for constructing the storage or reservoir.
- The land should be cheap in cost and rocky in order to withstand the weight of large building and heavy machinery.
- There should be possibility of providing adequate transportation facilities so that the necessary equipment and machinery could be easily transported.
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.
What do most power plants use to turn a generator?
Steam, created by heating water through the burning of fossil fuels or through nuclear reactions.
Overall hydro power safe than fossil fuel systems and nuclear as the are are no site air emissions, no waste and no thermal degradation of water.
The creation of hydro power usually requires the diversion of the water at an existing waterfall or the creation of a reservoir. The diversion of a waterfall may not cause problems as the water is eventually released to the same water course. The hydro power reservoir with its associated dams is another case. These systems can:
- be an impediment for spawning fish
- flood ecosystems
- result in methane losses from decomposing drowned vegetation
- change the hydrodynamics of the lower reaches of rivers
Hydroelectric power is produced when water is dammed or concentrated to one point: turbines. The turbines spin as the rushing water speeds down the pipes or dam. As the turbines spin, they also turn a generator which needs movement to provide energy. The electricity produced by a generator is then transfered to power lines which carry electricity for hundreds of miles.
What is good about hydro energy and what's bad about hydro energy?
the good thing about hydro energy is that water (hydro) is all around us so we will pretty much never run out of it. the bad thing is it's hard to control
Where does tidal energy have to be sited?
Anywhere where the tides move fast through a narrow entrance. This makes it economical to install a tidal energy system.
in the sea
How does the general public feel about hydroelectric power?
he general public would not feel comfortable using hydroelectic power because, why should they waste all this money to make the machines for it? I would want that cause shouldn't the public reserve the earths energy?
he Earths energy wont be lasting forever you know.
How is Hydroelectricity collected and then turned into useable energy?
If a dam is built across a river, water can be allowed to flow in a controlled way through turbines that generate electricity.
Almost all electrical energy is produced as a result of hydroelectric power?
NO. Almost all electrical energy is produced as a result of burning fossil fuels.
How much does it cost to replace hydro mast?
The cost to replace a hydro mast typically ranges from $300 to $1,500, depending on factors such as the type of mast, labor rates in your area, and any additional repairs needed. For more accurate pricing, it’s best to obtain quotes from local service providers. Additionally, insurance coverage may help offset some of the costs if applicable.
How is electricity generated in hydro electricity power plants?
Hydroelectricity is electricity generated by hydropower, i.e., the production of power through use of the gravitational force of falling or flowing water. It is the most widely used form of renewable energy. Once a hydroelectric complex is constructed, the project produces no direct waste, and has a considerably lower output level of the greenhouse gas carbon dioxide (CO2) than fossil fuel powered energy plants. Worldwide, hydroelectricity supplied an estimated 816 GWe in 2005. This was approximately 20% of the world's electricity, and accounted for about 88% of electricity from renewable sources.
Industrial hydroelectric plantsWhile many hydroelectric projects supply public electricity networks, some are created to serve specific industrial enterprises. Dedicated hydroelectric projects are often built to provide the substantial amounts of electricity needed for aluminum electrolytic plants, for example. In the Scottish Highlands of United Kingdom, there are examples at Kinlochleven and Lochaber, constructed during the early years of the 20th century. The Grand Coulee Dam, long the world's largest, switched to support Alcoa aluminum in Bellingham, Washington, United States for American World War II airplanes before it was allowed to provide irrigation and power to citizens (in addition to aluminum power) after the war. In Suriname, the Brokopondo Reservoir was constructed to provide electricity for the Alcoa aluminum industry. New Zealand's Manapouri Power Station was constructed to supply electricity to the aluminum smelter at Tiwai Point. As of 2007 the Kárahnjúkar Hydropower Project in Iceland remains controversial.What type of fuel is used to run most power plants?
If you mean nuclear plants, it is usually uranium oxide with the uranium enriched to about 4 percent U-235. The form is of small cylinders 10 mm diameter encased in zirconium tubes, and these tubes are made up into bundles called the fuel assemblies, which are the units handled in fuelling and refuelling.
Has hydro-electric energy been successful in the past?
HYDROELECTRIC DAms are free energy souceonce inplemented.
yes
Is hydro power environmentally friendly?
Yes, and no.While it does not give off any emissions, it creates a tremendous problem with the environment of the river from which it is harvesting power. For example, a dam and turbine stop salmon from going up the river to spawn every year, hence greatly decreasing salmon populations. So in some ways it is, some ways it isn't.
hydro boost uses pressure created by the power steering pump to make pressing the brakes easier. they are used for a few reasons. the first is the lack of vacuum from the engine. like in a diesel. or a heavy duty gas application where the motor is under heavy load most of the time. the second reason is space.. IE there isn't enough room for a big vacuum can to assist the brakes
What are the bad things uses about hydroelectric power?
The dams that are made in order to harness the power of the water floods the near by area !
