Impacts of Fossil Fuels on World
Fossil Fuels
Fuel formed by the process of anaerobic decomposition of dead organic material under earth crust over million years is known as “Fossil Fuel”. It contains organic material which gives energy on combustion.
Concept
Such fossil fuels generally have million years age and sometimes life is more than 650 million years. They contain great ratio of carbon, coal, petroleum and natural gas. Fossil fuels are known as primary source of energy. Total almost 85% energy usage is given by fossil fuels. In which petroleum accounts for 34% , coal 27% and natural gas 24%. Thus they are major primary source of energy.
Composition
Fossil fuels contain coal, petroleum, heavy oils and natural gas. Carbon is their vital part. They give great amount of energy under combustion.
Impacts on World/Environment
Fossil fuels are very important for our energy requirements. They have both good and bad effects. With being primary source of energy they also increase the temperature of global which causes several bad impacts on our planet. Thus they have advantages and disadvantages too. We will discuss them below:
Advantages of Fossil Fuels
There are few advantages of fossil fuels:
Cheaper source of energy
Fossil fuels are very cheap source of energy. Extraction process can be costly but in these days new technologies are more efficient and extraction of fossil fuels has become less costly and the quality is also better than before.
Economic benefits
Fossil fuels can affect country’s economy. Fuels like oil and gas generating countries can be economically strong. They can rely on fuels for their economic prosperity. By this we can guess the importance of fossil fuels in our life.
Stability
They consist of carbon and hydrogen and are highly stable due to the bond between them. This quality makes them capable to store for a long period because they do not react with other components when they are stored in cans. So this is also the reason behind their easy and safe transport.
Safe transport
They are stable and can be transported from one place to another without any harm. They can also be sent over long distances. Fossil fuels can be transported in huge trucks and in pipes and they are not the expensive transport methods. Thus they are safe to transport.
Excessive
Fossil fuels are abundant. They are enough to fulfill the requirements of people. They can be found in almost every country.
Reliable
They are reliable. They can give guaranteed supply of electricity as compare to the other sources like sun and wind.
Disadvantages of Fossil Fuels
Here are some disadvantages of fossil fuels;
Non renewable
They are not renewable. Their life is limited and they cannot be renewed before their specific time.
Environment pollution
Fossil fuels cause environmental pollution. Their combustion can cause air pollution. They increase the heat which rise temperature and then global warming is increasing day by day.
Affect on human health
Their combustion can cause dangerous health problems like heart problems and asthma etc. Fossil fuels are harmful for human health.
Impact on aquatic life
Sometimes while transporting fossil fuels leakage occurs like in oil tanks etc, the oil mixed up with water of seas and oceans and affects the aquatic life dangerously. In refinery processes crude oil can mix into water and block the oxygen for aquatic species which can cause their death. Thus they have harmful affect on aquatic life.
Conclusion
Fossil fuels are vital source of energy. They are useful in energy resources. But they can be harmful by some aspects too.
