PowerPoint Presentation:

What are fossil fules? Fossil fuels are non renewable sources.They are formed by natural Processes such as anaerobic decomposition of buried dead organisms.

PowerPoint Presentation:

What are the different types of fossil fuels? Three major fossil fuels are: 1.coal 2.oil 3.Natural gas

PowerPoint Presentation:

IMPORTANCE OF FOSSIL FULES: 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. Petro chemical refinery In U.K

PowerPoint Presentation:

2.Commercial exploitation of petroleum, largely as a replacement for oils from animal sources(whale oil) , for use in oil lamps began in the 19th century. 19 th century lamp

PowerPoint Presentation:

3.Natural gas, once flared-off as an unneeded byproduct of petroleum production, is now considered a very valuable resource. 4.The other major use for fossil fuels is in generating electricity and as feedstock for the petrochemical industry. Coal plant & wind turbines

PowerPoint Presentation:

4.Tar, a leftover of petroleum extraction, is used in construction of roads. Tar clin at sweden Process of pyrolysis

PowerPoint Presentation:

5.The invention of the internal combustion engine and its use in automobiles and trucks greatly increased the demand for gasoline and diesel oil, both made from fossil fuels. 2 stock internal combution engine

PowerPoint Presentation:

6.The widescale use of fossil fuels, coal at first and petroleum later, to fire steam engines enabled the Industrial Revolution Simplified triple-expansion engine.High -pressure steam (red) enters from the boiler and passes through the engine, exhausting as low-pressure steam (blue) to the condenser.

PowerPoint Presentation:

ENVIRONMENTAL EFFECTS The combustion of fossil fuels more than 90% of greenhouse gases are emitted. Combustion of fossil fuels also produces other air pollutants, such as nitrogen oxides, sulfur dioxide, volatile organic compounds and heavy metals. In this volatile organic compounds causes acid rain.It affect the wild life.

ALTERNATIVES : 1.Solar energy 2.Nuclear energy 3.Hydroelectricity 4.Wind energy 5.Geothermal energy

PowerPoint Presentation:

RENEWABLE ENERGY SOURECES: 1.Solar energy: Solar energy is the energy derived from the sun through the form of solar radiation. Solar cell

PowerPoint Presentation:

2.Nuclear energy: Nuclear power is the use of sustained nuclear fission to generate heat and do useful work. Nuclear power plant

PowerPoint Presentation:

3.Hydroelectricity: Hydroelectricity is the term referring to electricity generated by hydropower the production of electrical power through the use of the gravitational force of falling or flowing water. Largest hydroelectric powerplant -china

PowerPoint Presentation:

4.Wind energy: Wind energy is the kinetic energy of air in motion. Wind power in an open air stream. Wind turbines

PowerPoint Presentation:

5.Geothermal energy: Geothermal energy is thermal energy generated and stored in the Earth. Steam rising from the geothermal power station

PowerPoint Presentation:

Conclustion fossil fuels are non-renewable. They are limited in supply. Burning fossil fuels creates carbon dioxide, the number one greenhouse gas contributing to global warming.

PowerPoint Presentation:

No single solution can meet our society's future energy needs. The solution instead will come from a family of diverse energy technologies that share a common thread -- they do not deplete our natural resources or destroy our environment.
