The use of Fossil fuels, such as coal and oil, belongs the past.

Fossil fuels are natural fuels that are formed when remains of dead organisms pass through episodes of natural processes such as decomposition and disintegration; that exceeded millions of years. Fossil fuels include coal, oil and natural gas; they are categorized as fuels due to their ability to release energy when they undergo combustion. Meanwhile, they are the main source of producing the energy that is consumed by humanity. The scope of this essay will discuss the different advantages and disadvantages of using fossil fuels as sources of energy and alternative energy sources and methods discovered by environmentalists that are more environmentally friendly.

Fossil fuels are non-renewable meaning that they can deplete sooner or later. Fossil fuels in particular need millions of years to get formed meaning that we cannot produce them when they are diminished. But we cannot neglect their several advantages, which include their high availability and accessibility. Coal for example, is currently the most prominent source of electricity and is considered, along with oil, as one of the most abundant energy sources. As for oil, it is also easily transported and relatively cheap compared to other energy sources. Also, both coal and oil have the sufficiency to produce great amounts of energy and have a high calorific value making them very effective. Furthermore, coal and oil can also be both imported and exported by different countries enhancing trade and economic wellbeing.

However, even though fossil fuels are used constantly, they cause harmful effects on our environment. For a start, the burning of fossil fuels is the major factor causing pollution globall...

... are also substitutes to fossil fuels based engines and they are highly beneficial as they can’t pollute the environment with their emissions and they can include hybrid cars. As bio fuels cost less hybrid cars or green cars have a less maintainer cost. They also are unlimited resources of energy. Yet, green engines are extremely expensive to produce and buy and they also require consumers to buy and change their engines completely, which hinders consumers from making this change.

To conclude, although fossil fuels are highly available, produce great amounts of energy and are easily transported, but they cause huge damage to both humans and the environment. This is why renewable energy sources such as solar and wind energy, biofuels and green engines are considered as alternatives because they cause less harm to the environment although they are more expensive.

Fossil Fuels and Alternative Energy Sources Essay

- Fossil fuels are an important part of life. When you turn on the lights, watch TV, or take a shower, the electricity that you are using is being generated by fossil fuels. The three types of fossil fuels are coal, crude oil, and natural gas. They all take millions of years to form, so they are considered to be “non-renewable”- eventually, the fossil fuels will all be used up. One dangerous biological effect of using fossil fuels is ocean acidification. Extracting and transporting fossil fuels can also be very dangerous....   [tags: Energy]
