Question by Midzy: how does a geothermal power station work?
is the power converted into wind energy? :s but how?
i mean how does this thing provide electrical power to houses and all..
does it use steam to spin the turbine?
Best answer:
Answer by ammassridhar Geothermal power (from the Greek words geo, meaning earth, and therme, meaning heat) is energy generated by heat stored beneath the Earth’s surface or the collection of absorbed heat in the atmosphere and oceans.
Prince Piero Ginori Conti tested the first geothermal generator on 4 July 1904, at the Larderello dry steam field in Italy.
The largest group of geothermal power plants in the world is located in The Geysers, a geothermal field in California. As of 2007, geothermal power supplies less than 1% of the world’s energy.
Question by Lonely Spirit: What are the physics principles of geothermal energy?
What are the physics principles used by devices used for geothermal energy? It doesn’t matter what type of geothermal extraction is being used, but if anyone has some good physics principles that would be great :D
Best answer:
Answer by Lou Go back to the laws of thermodynamics. They will give you all the limits,
you cannot extract all the heat, you will have to put out some waste heat, and
if you use a Carnot cycle as a heat pump, what “efficiency” you could obtain.
Question by : Will geothermal energy be a big hit for us?
We’re looking at purchasing a home with geothermal energy. Right now we have the traditional central air and propane heat. Can anyone tell me stories (good and bad) of their experience with geothermal energy? I’ve heard it’s expensive to install (but that’s already done for us) that’s about all we know. Anyone have a difference in bills? Big difference, small difference?

Answer by Money saving Coach Hi Lacey,
As far as I know, The Queen of England and other high net-worth people like the singer Elton John have already equipped geothermal heating system for their estates. But can the ordinary householder tap into geothermal energy and save money on heating and electricity bills? Yes, for the price of a small car it is possible to drill hundreds of feet into the ground and you can not only reduce heating and electricity costs by around 70% but you can also benefit from a free supply of pure water.

Question by lil joker: Which of the following is an advantage of using geothermal energy to produce electricity?
A) Geothermal energy comes from heat deep under the earths surface.
B) the major uses of geothermal energy is to generate electricity.
C) it is very expensive to build a geothermal power plant.
D)Geothermal energy is a free energy resource.
Best answer:
Answer by Marcia A) is a statement of fact and not specified as an advantage
B) From what I understand geothermal energy to be, this one is false
C) is a disadvantage rather than an advantage
D) is the only answer presented as an advantage

Question by ǝƃɐʞǝpuɐd: What is the effectiveness of geothermal power?
Is there a country that takes a large percentage of power (at least 10%) from this method?
Best answer:
Answer by Percy I strongly suspect that Iceland would be in with a chance of taking the title and New Zeeland would run a close second. Have you checked Wikipedia for geothermal power?
Question by Cara: Why are geothermal energy and solar energy power plants good alternatives,?
but at the same time not always easy to have?
A. Both are nonpolluting and inexpensive to maintain, but their startup costs and limited locations make them difficult to have everywhere they might be needed.B. Geothermal energy may cause unwanted volcanic activity while solar energy is not useful unless the Sun is shining.C. The operating costs of both are too high.D. Geothermal energy can cause pollution, but both geothermal and solar energy are easy to capture.
Best answer:
Answer by Lennard Boehnke If either is used by a private home, the energy supplying company will pay you for whatever extra power you have, if you send it to them.
Question by Bobby: How does geothermal energy not contradict the second law of thermodynamics?
If entropy increases because of increasing amounts of heat, how does geothermal energy, which basically gets energy out of the heat in the earth, not contradict the second law of thermodynamics?
Best answer:
Answer by MarcThyme The Second Law of Thermodynamics applies to a CLOSED system (like, for example, the Universe); the planet Earth is NOT a “closed system”, it is both receiving energy from and losing energy to the Universe around it….
