"Fossil fuels, even when burned perfectly (natural gas, or methane, burns the best) release carbon dioxide which is a greenhouse gas causing dangerous global warming. Most fossil fuels also release smoke (leading to smog), and they may also release sulfur oxides and nitrogen oxides which contribute to acid rain."

"Geothermal energy uses hot water or steam from deep in the Earth. As a consequence it does not require fuels which produce emissions. However there are hot water (condensate) releases which may cause thermal pollution."

"Fossil fuel power stations typically cost about $2.1 dollars per watt to build solar stations around $7 at present. The efficiency is increasing and costs are falling. This of course does not represent the cost to the consumer. In addition it does not take into account all the various other costs and the advantages and disadvantages of each. Fuel (fossil stations), poor sunlight (solar stations). Maintenance costs are similar for single plants but solar stations do not have the capacity of fossil fuel stations."

"Geo thermal systems heat and cool your house cheaper and better than fossil fuels will with gas going up pretty soon you would not be able to afford it. It might be costly to put one in your house initially but it will pay itself off in 3-5 years. Also there is a company called ECONAR that builds a heat pump that will cool, heat, and do 50 to 100% of your hot water heat. Fossil fuels also produce carbon dioxide when burnt, adding to the greenhouse gases and contributing to climate change."

""Geothermal energy has the potential to generate and deliver sustainable supplies of clean, renewable base load power. Depending on the nature of the resource and the reservoir, individual production wells have the potential to generate consistent supplies of base load power for decades.""

"The Solutions With current technology, renewable energy sources like wind, solar, and geothermal can provide 96% of our electricity and 98% of our total heating demand - accounting for almost all of our primary energy demand."

"Geothermal energy is the heat from the Earth. It's clean and sustainable. Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma."
