Every day, you and everyone you know use energy. We need energy to heat and cool our buildings, provide us with lights when it is dark outside, and to get us from place to place. Energy is even used to print on paper. The main sources of energy that we use everyday are fossil fuels. Pick three fossil fuels and include supporting details to explain how they are used. *

Answer:
I am mentioning about 3 fossils
Explanation:
- Fossil-Asphalt
Details/uses:-Asphalt is a black or brown petroleum-like material that has a consistency varying from viscous liquid to glassy solid. .Asphalt consists of compounds of hydrogen and carbon with minor proportions of nitrogen, sulfur, and oxygen.There are two types of asphalt which are natural asphalt and residual petroleum asphalt.Natural asphalt (also called brea), which is believed to be formed during an early stage in the breakdown of organic marine deposits into petroleum, characteristically contains minerals, while residual petroleum asphalt does not.
The use of asphalt is very old, dating back to its use as a water stop between brick walls of a reservoir at Mohenjo-Daro (about the 3rd millennium BC) in Pakistan. In the Middle East it was extensively used for paving roads and sealing waterworks, important applications even today. The Pitch Lake on the island of Trinidad was the first large commercial source, but natural sources have since declined in importance as petroleum became the major source. Gilsonite, wurzilite, and similar vein asphalts have special uses in heat-resistant enamels; they are hard and are mined like coal. Petroleum asphalt is produced in all consistencies from light road oils to heavy, high-viscosity industrial types.
Asphalt softens when heated and is elastic under certain conditions. The mechanical properties of asphalt are of little significance except when it is used as a binder or adhesive. The principal application of asphalt is in road surfacing, which may be done in a variety of ways. Light oil “dust layer” treatments may be built up by repetition to form a hard surface, or a granular aggregate may be added to an asphalt coat, or earth materials from the road surface itself may be mixed with the asphalt.
- Fossil-Bitumen
Bitumen is a dense, highly viscous, petroleum-based hydrocarbon.There are two types of bitumen.Natural bitumen is the bitumen which is found in deposits such as oil sands and pitch lakes and refined bitumen is the type of bitumen which is obtained as a residue of the distillation of crude oil.
Bitumen is defined by the U.S. Geological Survey as an extra-heavy oil with an API gravity less than 10° and a viscosity greater than 10,000 centipoise.
In addition, bitumen frequently has a high content of metals, such as nickel and vanadium, and nonmetallic inorganic elements, such as nitrogen, oxygen, and sulfur. Depending on the use to which bitumen is put, these elements may be contaminants that have to be removed from the finished product. By far most refined bitumen is used in paving asphalt and roofing tiles, as is a large amount of natural bitumen. However, most of the bitumen extracted from Canada’s oil sands is upgraded into synthetic crude oil and sent to refineries for conversion into a full range of petroleum products, including gasoline.
- Fossil:Peat
Peat is actually a fuel.Peat is a fuel consisting of spongy material formed by the partial decomposition of organic matter, primarily plant material, in wetlands such as swamps, muskegs, bogs, fens, and moors. The development of peat is favoured by warm moist climatic conditions; however, peat can develop even in cold regions such as Siberia, Canada, and Scandinavia.
Peat is only a minor contributor to the world energy supply, but large deposits occur in Canada, China, Indonesia, Russia, Scandinavia, and the United States. In the early 21st century the top four peat producers in the world were Finland, Ireland, Belarus, and Sweden, and most of the major users of peat were these and other northern European countries. Peat is sometimes considered a “slowly renewable energy” and is classified as a “solid fossil” rather than a biomass fuel by the Intergovernmental Panel on Climate Change (IPCC). Although peat is not strictly a fossil fuel, its greenhouse gas emissions are comparable to that of fossil fuels.
The uses of Peat are:
Dried peat burns readily with a smoky flame and a characteristic odour. The ash is powdery and light, except for varieties that have a high content of inorganic matter. Peat is used for domestic heating purposes as an alternative to firewood and forms a fuel suitable for boiler firing in either briquetted or pulverized form. Peat is also used for household cooking in some places and has been used to produce small amounts of electricity.
In horticulture, peat is used to increase the moisture-holding capacity of sandy soils and to increase the water infiltration rate of clay soils. It is also added to potting mixes to meet the acidity requirements of certain potted plants. Given that peat harvesting is destructive to wetland habitats, its use as a soil amendment has been discouraged by conservationists.
Peat can be used in water filtration and is sometimes utilized for the treatment of urban runoff, wastewater, and septic tank effluent. It is also used to soften aquaria water and to mimic habitats for freshwater fish.
