Conservation Of Fossil FUels

Fossil fuels  are  fuels  formed by natural processes such as  anaerobic decomposition  of buried dead  organisms . The age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years. Fossil fuels contain high percentages of  carbon  and include  coal ,  petroleum , and  natural gas . They range from  volatile  materials with low  carbon : hydrogen  ratios like  methane , to liquid petroleum to nonvolatile materials composed of almost pure carbon, like  anthracite  coal. Methane can be found in  hydrocarbon  fields, alone, associated with oil, or in the form of  methane clathrates . The theory that fossil fuels formed from the  fossilized remains  of dead plants by exposure to heat and pressure in the Earth's crust over millions of year (see  biogenic theory ) was first introduced by  Georg Agricola  in 1556 and later by  Mikhail Lomonosov  in the 18th century. Fossil Fuels

Ride a bike or walk more.  Instead of driving a car or taking a bus, try cycling or walking to your destination. This isn't just great for reducing your fossil fuel use; it's also ideal for keeping you fit and healthy.Kit yourself out with a good bike and safety gear. Look after both  bike and gear  so that they last a long time. Find cycleways wherever possible. These are safer than doing the tango with cars, trucks and semis. Use lighting at night to stay safe and see where you're headed. No cycleways ? Contact your local municipality and campaign for some to be added where you live. H o w Can We Conserve Fossil Fuels

Fossil Fuels Disadvantages Fossil fuels  are one of the greatest threats to the environment today. Their burning contributes heavily to global warming, the pollution of the air, water and land, as well as the production of acid rain.   When fossil fuels are burned huge amounts of carbon are released into the air. This contributes to the greenhouse effect, causing the sun’s warmth to be excessively trapped in the atmosphere. When this occurs, global temperatures rise. Melting of the  polar ice caps  causes ocean levels to rise as well

Importance Of Fossil Fuels Fossil fuels are of great importance because they can be burned ( oxidized  to  carbon dioxide  and water), producing significant amounts of energy per unit weight. The use of  coal  as a fuel predates recorded history. Coal was used to run furnaces for the melting of metal ore. Semi-solid hydrocarbons from seeps were also burned in ancient times, but these materials were mostly used for waterproofing and  embalming .

Fossil Fuels Origin Petroleum and natural gas are formed by the  anaerobic decomposition  of remains of organisms including  phytoplankton  and  zooplankton  that settled to the sea (or lake) bottom in large quantities under  anoxic conditions , millions of years ago. Over  geological time , this  organic   matter , mixed with  mud , got buried under heavy layers of sediment. The resulting high levels of  heat  and  pressure  caused the organic matter to chemically  alter , first into a waxy material known as  kerogen  which is found in  oil shales , and then with more heat into liquid and gaseous hydrocarbons in a process known as  catagenesis . There is a wide range of organic, or hydrocarbon, compounds in any given fuel mixture. The specific mixture of hydrocarbons gives a fuel its characteristic properties, such as boiling point, melting point, density, viscosity, etc. Some fuels like natural gas, for instance, contain only very low boiling, gaseous components. Others such as gasoline or diesel contain much higher boiling components.

Daily life conservation Solar power is a promising, renewable energy resource than can be turned into electricity, and it is used in many toys and even home heating In our everyday lives, we can also work to conserve energy. Insulating, turning off lights and only using appliances like dishwashers when they are full are just some of the ways people can limit energy use in their homes. Also, carpooling, bicycling, and taking public transportation are effective energy-saving ideas.

Car Pool Recycle Reuse Shut off & unplug when not in use Use alternative energy sources Conserve Energy

Wind Power Solar Energy Plant based Energy Geothermal Biomass Water power Alternative Energy Sources

Wind Energy Wind power is increasingly being used as a clean source of renewable energy. Turbines harvest wind on wind farms and generate electricity

Factory and Hydroelectric plants There are many renewable energy sources that are alternatives to fossil fuels, but some are not without controversy. For instance, nuclear power is used to generate about 25 percent of the world’s electricity, but it has inherent risks, especially in the disposal of radioactive waste. Hydroelectric plants use running water to generate electricity, however they may flood nearby lands and can disrupt the normal flow of water, both of which negatively affect the environment

Fossil Fuels are a Non-Renewable source of Energy Coal, oil and natural gas, are a non-renewable source of energy Formed from plants and animals that lived up to 300 million years ago Found in deposits beneath the earth Burned to release the chemical energy that is stored within this resource Over 85% of our energy demands are met by the combustion of fossil fuels
