FOSIL FUELS.

Types: • Coal. • Petroleum. • Natural gas. They are created from the decomposition of plant matter or animal, which are extracted from the Earth due to remnants of fossils buried for millions of years and marine microorganisms. According to the energy information administration, 91% of the coal burned in the United States is used for the production of electricity. Approximately 70% oil is used for transportation.

Time frame. The use of carbon-based fuels began at the end of the 18th century. The industrial revolution was heralded by the use of coal. The invention of the steam engine and its subsequent use in the mechanization of the British textile industry is given credit as the kicker of the revolution, since coal was used as fuel for steam engines the natural gas contains less contamin before (including carbon) than other fossil fuels.

Effects. "Modern society" would not have developed without these high-energy fuels. However, the use of coal for energy produces sulphur, nitrogen oxide and mercury among many other pollutants emissions. This negatively affects the entire biomes of the Earth, causing storms, acid rain, greenhouse effect, climate imbalance. The oil also has other problems, such as spills and ground-level ozone produced by engines run on petroleum-based fuels. Warfare by seizing oil since it is economically very profitable. While natural gas is cleaner than oil and coal, still emits practically all the same pollutants, only in smaller amounts.

Potential It is the goal of many Governments and organizations to limit the use of fossil fuels. There are technologies such as "scrubbers" pollutants and carbon sequestration techniques that may allow the continued use of coal. The potential of these energy sources has already taken account.

Present.

Alternatives Generate energy and industrial policies that go by moving their employment in non-conventional energy power generation.

The clean coal Clean coal describes a set of technologies and improvements designed to reduce the environmental impact of burning coal as fuel. Without guarantees, burning coal releases large amounts of GHG into the atmosphere. Other carbon by-products include mercury, lead and acid rain. Clean coal involves a technology that eliminates impurities from the coal before burning it.

FUN FACTS. 1. All fossil fuels are the result of the decomposition of plants which took place millions of years ago under water. 2. The most recent discovery of an untapped oil deposit was made in Alaska, where it is thought that the ice covered a sea that existed millions of years ago. 3. Coal, oil and natural gas are fossil fuels. Currently, statistics show that at the global level these fuels provide more than 85% of the energy we consume. 4. The search for oil required to study the type of rock that is under the Earth's surface. Crude oil lies in underground areas called deposits and can be turned into products such as gasoline and electricity. 5. Natural gas is a form of methane that is trapped in "pockets" where there was plant decomposition. New experiments are trying to discover how to get methane from Fossil fuels are not a source of renewable energy, because it takes millions of years to occur. 6. It is estimated that given the pace to which consume fossil fuels and the prediction of discoveries of new deposits, these sources of energy will be exhausted within 100 or 200 years. 7. Fossil fuels are used commonly on the planet because it is easy to convert them into energy. They are made based on hydrocarbons and just burn them so they release energy. 8. Americans use about 18 million barrels of oil every day. 9. Toxic gases that pollute the air and cause serious health problems are released when fossil fuels are burned.
