How much Wind Turbines Does it take to Make the Energy in a Power Plant?

Best answer:

Answer by MTRstudent
Your question is confusing!

Do you mean: how many wind turbines does it take to produce the same power output as a power station?

The answer depends on a lot of things. Modern power stations vary in size. A ‘typical’ one is somewhere between 1000MW and 1600MW. (but you can get bigger ones – Drax is over 4000MW)

Wind turbines tend to be between 1.5MW and 3.6MW each, but 5MW models are being released this year and 7.5MW and 10MW ones are being researched.

So at maximum output, a 1600MW coal power station would require about 640 2.5MW turbines to match it. Or 320 of the new 5MW turbines.

The total amount of energy produced is different though; wind turbines on average only produce ~30% of their total possible output (ie their ‘capacity factor’ is about 30%). Nuclear power stations, because of their low marginal cost, tend to have a ‘capacity factor’ of 90% or so. Other power stations like coal and gas may be anywhere from 40-90%, but the US average is 55%:

So a 1600MW coal power station will average 880MW output. You’d need almost 1200 2.5MW turbines to get the same average power output; or 600 new 5MW models.

Question by Akhil R P: Where is this much of energy in a nuclear fission or fusion?
When is the energy coming from fission or fusion.
Where is this much of energy been saved.
Please explain.
How this mass is converted to Energy?

Best answer:

Answer by Gee Whiz
In addition to decaying, a nucleus can be transformed in two other important ways: fission and fusion. The isotope iron-55 is the most stable nucleus. Atoms with higher mass will tend to go through fission and give off energy while atoms with mass lower than iron-55 can go through fusion to become more stable and give off energy.
Fission -If an unstable nucleus breaks into two smaller pieces, it can form two new atoms. This is known as fission. When this occurs some energy is also released. This is the source of energy that powers nuclear power plants and the first nuclear bomb.

If two nuclei collide with enough force then they may fuse together forming a larger single nucleus. This is known as fusion. When this occurs some energy is also released. This is the source of energy that powers the sun (as well as other stars) and hydrogen bombs.

nuclear reactions can produce an enormous amount of energy. Both fission and fusion produce energy in this way. A bomb releases the energy all at once while a nuclear power plant releases the energy slowly over very long periods of time. Currently we don’t have any way to control a fusion reaction. All nuclear power plants in operation today use fission to produce energy.
Fusion reactions similar to the one described above are the source of power for the Sun and other stars. Notice how the lighter hydrogen nuclei fuse to form a heavier helium nucleus. Inside the sun heavier and heavier atoms are then fused together to form more and more elements. That is where all of the elements heavier than helium have come from – inside a sun.

Question by hi: how much % of light coming in to solar cells is changed to electricty?
the efficency of a solar cell

Best answer:

Answer by roderick_young
From Wikipedia:

Solar cell efficiencies vary from 6% for amorphous silicon-based solar cells to 40.7% with multiple-junction research lab cells and 42.8% with multiple dies assembled into a hybrid package.[26] Solar cell energy conversion efficiencies for commercially available multicrystalline Si solar cells are around 14-19%.[27] The highest efficiency cells have not always been the most economical — for example a 30% efficient multijunction cell based on exotic materials such as gallium arsenide or indium selenide and produced in low volume might well cost one hundred times as much as an 8% efficient amorphous silicon cell in mass production, while only delivering about four times the electrical power.

—
And my comment: after the cells are put into practical panels, subtract another few % of efficiency. So 14% would be pretty typical for a crystalline panel you buy on the open market.

Question by Lame O: Why is everyone so into solar energy and wind energy? When nuclear energy is so much more powerful?
We all know how much more powerful nuclear energy is. I don’t get it, is it a fad? Solar and Wind energy is a waste of land and ineffective. Yea the technology is probably going to improve, but so is nuclear technology. I don’t know much about this stuff, this is simply my assumption.

Question by Ethan Tom: how much supplies would me and 5 to ten people need for a trip to mars using an ion engine?

im doing a science project where we have to create a colony on another planet

Best answer:

Answer by Stephen
How big an engine? With an ion engine you are going to be accelerating very slowly, so you might need anywhere from a few months to a few years to reach Mars.

Also, you did not say if you want to come back again, if you want to descend to the Martian surface, or if you want to explore while there.

Question by Question Man: How much does a geothermal power plant cost?
I need to make a commercial for a school project about alternate energy sources. I have picked geothermal. I am needing every little bit of info if someone can get me a website with this info i would greatly appreciate it. My most important information would be how much one costs and how long does it averagely take to pay its self off.

Best answer:

Answer by Breath on the Wind
The initial cost of a facility will vary based upon installed KW ” around 00 per installed kW in the U.S., probably 00 to 00/kWe for a small (<1Mwe) power plant. Operating and maintenance costs range from .01 to .03 per kWh.” This is comparable to the cost of running a coal fired plant. But while most coal fired power plants have a capacity factor of about 75%, “most geothermal power plants can run at greater than 90% availability” 1

Question by billy25685: How much fluid will flow out of a 20″ pipe assuming 5000psi?
Since BP engineers and the US government can’t finalize their numbers, I’m betting the Answers Community has a good answer.
There were some pressure ratings called out during the “top kill” operation, let’s assume 5000psi.
Yes some mud and gas is coming out of the pipe but for simplicity just assume all fluid flow.

Best answer:

Answer by jpopelish
In effect, something like 5000 psi is being used up to push oil and gas up through about two miles of well bore and pipe. How much that pressure will deliver depends on the bore diameter and roughness of that two miles, what else in in there (the drill pipe) and the viscosity of the fluid. It is not a simple calculation. Besides, I haven’t heard how much of that 2 mile deep bore holds drill pipe, and how much is unobstructed. Oh, only the riser pipe above the blow out protector has a 21 inch diameter. The well casing below the BOP is much smaller and the uncased bore below that casing is a bit larger than the casing, but is still smaller than 21 inches. And it is a good thing, because a 21 inch bore pipe, all the way to the reservoir would deliver several (10?) times as much oil as we are seeing.

[8x8 inch per min]

Best answer:

Answer by jpopelish
1 watt to a few watts (joules per second) in full sunlight. The combination of volts and amps that produce that couple watts depends on how many cells are connected in series. (figure about a third of a volt per cell).

Question by Anonymous: How much time for Vasimr to get to other planets?
I heard of something called Vasimr on the Science Channel, I was watching Earth Exodus. It said it could get us to Jupiter in a matter of months. So, the question is, how much time to be exact to get to Mars, Luna (The Moon), and/or Jupiter?

3 months (or in some estimates only weeks) to get to Mars. So I guess that makes hours to go to the moon. Interplanetary conquest, here we come!

The most I had ever paid for an electric bill prior to this was 70 for a 3-month period (2-person apartment connected to central heating). Last month I moved to a 1-person place that is NOT connected to central heating (instead uses 3 electric space heaters). I don’t have many appliances and I try to conserve electricity whenever I can, but this month my bill was 135 for the same 3-month period!!!

I realize that space heaters are inefficient for energy use, but can they really affect my energy bill in such a drastic way???
