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 kinds of renewable energy are there?
Renewable energy comes from a renewable source, that is, that keeps on coming, like sun, wind, tides, ocean waves and geothermal heat (from deep under the ground).
Non-renewable energy comes from burning fossil fuels like oil, coal, wood and nuclear power. When we've used them all, there's none left.
So the renewable energy that we are harnessing is:
- Solar Power (using the sun to heat water and generate electricity)
- Hydro-electric power (from damming rivers)
- Wind Power (using wind turbines to generate electricity)
- Tidal Power (using the power of the tides to generate electricity)
- Ocean Wave Power (using the power of the waves to generate electricity)
- Geothermal Power (using heat from deep under the earth)
- Ocean Thermal Power (using the difference in temperature of surface and deep water) Biomass which is:
- producing biofuel like ethanol from vegetation.
- producing biogas by capturing methane (natural gas) from landfill sites and from animal and human sewage. * using vegetation to burn in steam generators. Burning it will release (very recently captured) carbon dioxide, but if we allow the vegetation to decompose it releases methane, a much more dangerous greenhouse gas.
What is the cost of maintaining a hydroelectric dam?
It costs about 0.7 cents per kilowatt hour (kWh) of electricity
There are: Hydro electric, Nuclear, Solar, Wind, and Fossil fuels, Geo- thermal and Biofuels.
Hydro electric has two categories : Tidal and Wave
What does a hydroelectric generator looks like?
Water moves through a pipe and spins a propellor of some kind. This spinning is then connected to a magnet, or a series of magnets which rotate inside stationary coils of copper wire. This generates electricity. So there are two spinning parts, the wet part providing the power, and the dry part generating electricity. The whole thing is usually built inside the bottom of a dam, but smaller ones are installed in river channels.
What is hydroelectricity made of?
Hydroelectricity is using the charges in water to create electricity, commonly exhibited through water falls.
Reply # 2. answer by rbbt - Hydroelectricity is the use of running/moving water to power generators that in turn create electricity. (Electricity created through the use of hydro - ie. water)
Does hydro electric power station produce CO2?
No because it does not burn any fuel, the energy comes from falling water that turns turbine blades.
How does a power plant look like?
It looks like a huge building with electrical things all around it. It is next to the entrance to the Rock tunnel but you need surf because you follow the river to get to it. Zapdos, level 50 is at the end.
How many hydroelectric plants exist in the US?
There area little over 850 Hydroelectric Power plants in the United States
How can water power be used for homes schools and businesses?
Water power is used to produce electricity - all homes schools and businesses use electricity so hydro power is just part of this.
If you mean direct water power using your own water wheel to drive some mechanism, this is rather old fashioned. Millers used to do this, but surely no-one still does this? I don't see any relevance to homes and schools, what would they do with a mechanical water wheel?
How much money needed to set up hidropower?
That depends how big is going to be; small hydro power stations could cost between 350 and 700 hundred thousand pounds ,and large ones cost millions of pounds.
How effective is hydroelectricity?
well, hydro electricity is water that falls into the blades of turbines and moves the turbines to make electricity.
Some advantages are that it is reliable, i am pretty sure it is renewable, it does not pollute the earth, and it is a natural resource.
Some disadvantages are that if it is not cared of properly then it may flood and kill wildlife, and i think it costs alot of money.
How do we get energy from Hydropower?
- Dams: Falling water spins turbines to generate electricity.
- Wave power: Ocean waves transfer their energy to moving machinery which generates electricity.
- Tidal power: Tidal water rushes through narrow channels turning electricity generators.
What is the advantage of dendrothermal power?
Dendrothermalpower plant has potential to be considered as one of the alternative technologies for a small agricultural community-based development in terms of electricity generation, economics feasibility and environmental impacts
If a fan uses 10 amps plugged into 120 volts AC what is the kWh used?
10 amps at 120 volts is 1200 watts or 1.2 Kw, so in 1 hour it will use 1.2 Kwh
Is hydroelectric power source good or bad?
Positives include the fact that it is an enormous reserve of renewable energy; negatives are that it can seriously impact an environment, and is not the most stable of sources.
