The dangers of plate techtonics are also a real consideration. The geothermal energy method takes advantage of the natural radiant heat from the core of the earth to power turbines. Areas that are suitable for geothermal plants are usually located near earthquake zones or places of volcanic activity. Iceland has managed to make this form a viable and efficient means of producing electricity, but geothermal energy is not a useful option for most areas. Our society is powered by fossil fuels.
Fossil fuels are all hydrocarbons formed from decaying organic matter under severe pressure.
Whether the reserve of organic matter was compressed to form coal, oil, or natural gas depends on the geography of the area in which it is deposited. Oil and Natural Gas Oil and natural gas are deposits remaining from ancient seas. These minerals soak into the permeable rock layer, which later undergoes intense pressure as the earth's crust flexes and contracts. Geologists perform land surveys to look for anticlime layers, which appear as folds in rock. Once approximately two thirds of a reserve is exhausted, it is necessary to re-pressurize to bring the remaining third of oil or natural gas to the surface.
