Question

Explain why geothermal energy is not a realistic option in all locations.?

Answer 1

Duh! In some places the geothermal source is buried way too deep to access.

You couldn't think of that????

Answer 2

Because geothermal energy is only readily available in certain locations (Yosemite, Iceland).  Otherwise you have to drill down pretty far to tap into it.

Answer 3

lack of surface stability due to ground movement, lack of enough groung water, magma is too close or too deep from the surface. each geothermal site has to be custom built to match the local conditions, which costs alot of money.  the bad thing is that the local conditions are always changing so the equipment needsconstant upgrading, which costs more money. the people if iceland  and the japanese have done amazing things with their geothermal sites.

Answer 4

There are several environmental concerns behind geothermal energy. Construction of the power plants can adversely affect land stability in the surrounding region. This is mainly a concern with Enhanced Geothermal Systems, where water is injected into hot dry rock where no water was before. Dry steam and flash steam power plants also emit low levels of carbon dioxide, nitric oxide, and sulfur, although at roughly 5% of the levels emitted by fossil fuel power plants. However, geothermal plants can be built with emissions-controlling systems that can inject these gases back into the earth, thereby reducing carbon emissions to less than 0.1% of those from fossil fuel power plants.

Although geothermal sites are capable of providing heat for many decades, eventually specific locations may cool down. It is likely that in these locations, the system was designed too large for the site, since there is only so much energy that can be stored and replenished in a given volume of earth. Some interpret this as meaning a specific geothermal location can undergo depletion, and question whether geothermal energy is truly renewable, but if left alone, these places will recover some of their lost heat, as the mantle has vast heat reserves. An assessment of the total potential for electricity production from the high-temperature geothermal fields in Iceland gives a value of about 1500 TWh or 15 TWh per year over a 100 year period. The electricity production capacity from geothermal fields is now only 1.3 TWh per year.

Answer 5

There has to be access to enough of the sub surface heat from the below the earths crust. at present we can only take advantage of what mother nature offers up to us at random geographic locations. The people of Iceland are lucky because they get to heat their homes and green houses to grow fresh vegies in the polar region.
