Natural gas is a gaseious fossil fuel consisiting primarily of methane and including amounts of ethane, propane, butane and pentane. Natural gas is also discussed under the “Geothermal Energy” article.
Natural gas can be found in oil fields, dissolved or isolaed natural gas fields, and in coal beds. When methane rich gases are produced by the [...]

Geothermal energy is energy obtained by tapping the heat of the earth itself, usually from kilometers deep into the Earth’s crust. It is expensive to build a power station but operating costs are low resulting in low energy costs for suitable sites. Ultimately, this energy derives from heat in the Earth’s core.
