Energy policy of Australia is subject to regulation and fiscal influence of the three levels of Government in Australia, however State and Federal energy policy deals with primary industries, such as coal. Federal energy policies continue to support the coal mining and natural gas industries through subsidies for fossil fuel use and production as these industries export and significantly contribute to the earnings of foreign exchange and government revenues.

Product Description
The geothermal gradient is the rate at which the Earth’s temperature increases with depth, indicating outward heat flows from a hot interior. Away from tectonic plate boundaries, it is 25-30°C per km of depth in most of the world. Strictly speaking, geo-thermal necessarily refers to the Earth but the concept may be applied to other planets. The Earth’s internal heat comes from a combination of residual heat from planetary accretion (about 20%) and heat produced thr… More >>

How does a geothermal power station work?

Posted by: admin | Comments (1)

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?

Despite the obvious advantages, geothermal energy comes at relative costs. For instance, it is for now fairly impossible to implement it on a large scale. Opponents of the idea of geothermal energy to produce electricity argue that it

Just to show you what I’m talking about:

http://en.wikipedia.org/wiki/Geothermal_power

Please read this if you don’t know what geothermal power generation is – I am NOT talking about geothermal heat pumps!!!

This form of power eletricity generation has the potential to completely replace fossil fuels sustainably for several thousand years and would solve the problem of climate change, reduce the use of water and land and the creation of other kinds of pollution (so even if you don’t support the notion of climate change it’s a good idea) and stop reliance on foreign owned oil at the same time. It is far cheaper to produce eletricity geothermally than through using “clean” coal or nuclear power and it can be done on small as well as large scales so you could create more efficient grids than with nuclear and not waste power by transporting it long distances.

The US and Australia are in the two best positions to exploit geothermal resources, what are we waiting for?
Just want to make people aware of something in the article in case they don’t look at it:

“The MIT report estimated that there was enough energy in hard rocks 10 km below the United States to supply all the world’s current needs for 30,000 years.”

and

“Drilling at this depth is now routine for the oil industry (Exxon announced an 11 km hole at the Chayvo field, Sakhalin. Lloyds List 1/5/07 p 6). The technological challenges are to drill wider bores and to break rock over larger volumes. Apart from the energy used to make the bores, the process releases no greenhouse gases. Compared to the difficulties of developing other forms of energy supply (nuclear, wind, wave, solar etc.) EGS seems to be well worth encouragement.”
1. There is more than enough available, extractable energy to power not just the entire US but the entire planet beneath the western US.

2. There are geothermal power companies in more than 20 countries around the world but they never get the press attention of solar, wind, nuclear or “clean” coal… it is still however financially viable though: cost of energy production is lower than nuclear and about a third of “clean” coal energy costs. This is an under developed power resource.

3. That is true, you need to pump in water if it isn’t already there though not much with binary systems…. it also does need to be done with care and with understanding of the underlying geology of the area. Not sure this is an issue because it can be overcome and there are still plenty of places (such as the US for one) with more than enough geothermal power resources to run their entire country on cheaply.
“A 2006 report by MIT that took into account the use of Enhanced Geothermal Systems (EGS) concluded that it would be affordable to generate 100 GWe (gigawatts of electricity) or more by 2050 in the United States alone, for a maximum investment of 1 billion US dollars in research and development over 15 years.”

1 billion dollars ain’t a whole lot, if this were getting a tenth the resources of solar, nuclear or “clean” coal then it would be very much financially viable.
Still waiting for this supposed email from Yupchagee – far as I’m concerned though it’ll take some strong proof from him to show how everyone else even opposed to geothermal power recognises that it causes very little to no emissions.

Is this a good way to increase the percentage of the worlds energy generation that is clean green and renewable? Would it be a good step in moving towards a world where all energy generation is clean green and renewable?

How to prove geothermal power plant does not violate the second law (especially in mathematic)
I know that it is a close system and it obey the internal energy conservation. But I hardly express it into mathematical to make it a stronger statement. Anyone can help please. Thank You.
