Fossil fuels are the remains of plants and animals from the prehistoric era, which have now reduced to mere hydrocarbon chains. These hydrocarbons are in the form of solids or liquids. Fossil fuels have a very high combustion rate and they release tremendous amount of energy. Most of our fuel and energy demands are met by the fossil fuels. Fossil fuels have increased the level of environmental pollution so much, that it has now become a serious environmental concern. Here, we have taken an overview of the advantages and disadvantages of fossil fuels.

Examples of fossil fuels:

Oil
Crude oil, is a liquid fossil fuel made up mostly of hydrocarbons (hydrogen and carbon compounds). Oil can be found in underground reservoirs; in the cracks, crevices, and pores of sedimentary rock; or in tar sands near the earth’s surface. It’s accessed by drilling, on land or at sea, or by strip mining in the case of tar sands oil.

Coal
Coal is a solid, carbon-heavy rock that comes in four main varieties differentiated largely by carbon content: lignite, sub-bituminous, bituminous, and anthracite. Regardless of variety, however, all coal is dirty. Indeed, in terms of emissions, it’s the most carbon-intensive fossil fuel we can burn.
Coal is extracted via two methods: Underground mining uses heavy machinery to cut coal from deep underground deposits, while surface mining removes entire layers of soil and rock to access coal deposits below.

Natural gas

Composed mostly of methane, natural gas is generally considered either conventional or unconventional, depending on where it’s found underground. Conventional natural gas is located in porous and permeable rock beds or mixed into oil reservoirs and can be accessed via standard drilling. Unconventional natural gas is essentially any form of gas that is too difficult or expensive to extract via regular drilling, requiring a special stimulation technique, such as fracking.

Most of the fossil fuel products that we use every day come out of the energy sector. That means we use them for fuel, heating oil, gasoline, and numerous consumer goods. Everything from ink to crayons to deodorant comes from the processing of fossil fuels. Out of the average 42-gallon barrel of oil that is consumed every day, more than 45% of it will be used in automotive gasoline. About 30% is used for either heating oil or diesel fuel. Then about 20% is used for personal products.

Fossil fuels are a technology that is globally developed.
We have numerous technologies available to us because of the presence of fossil fuels. Although this fuel source is often thought of as a way to provide transportation needs, many of the products that we use every day contain items that were manufactured thanks to fossil fuel technologies. That includes the computers and mobile devices that are used to read this content. Even renewable fuels have a foundation built on fossil fuels.

Fossil fuels are both cheap and reliable.
Because the technologies which surround fossil fuels are well-established, the consumer cost to use them is quite load. The energy that is produced by their refinement and combustion is incredibly consistent. If you pour gasoline into your vehicle, there isn’t a doubt that the fuel will fail to ignite. Fossil fuels give us a strong base load, reliable energy, and it can be created around the clock.

Fossil fuels contribute to the overall welfare of an economy.
We use fossil fuels to transport goods and services to one another. We are productive because of fossil fuels. We can generate renewable energy because of fossil fuels. We drive to the grocery store thanks to fossil fuels. Not only does the purchase of fossil fuels contribute to the national economy, but the use of fossil fuels helps to generate revenues for localized economies. Just about everything we do in life right now is tied, one way or another, to the consumption of a fossil fuel.

Fossil fuels are easier to extract and process, hence are cheaper than the non-conventional forms of energy.

It serves as the primary source behind the plastic products we use.

Although plastics can be created from biofuels, the majority of plastics that we use every day come from the fossil fuels industry. Up to 91% of the plastics we use are not recycled either, which means we need new plastics every year. In just 70 years, the global plastics industry has created more than 8 billion metric tons of virgin plastics. That means we could have built the Empire State Building 25,000 times using just plastic.
Without fossil fuels, these products and the jobs within the plastics industry would all go away.

They can be easily stored and transported.
One big advantage of using fossil fuels is that they can be easily stored and transported. Having a stable composition, they are strong enough to be carried from one place to another.

Fossil fuels are priced through three different market influences. They are traded as a commodity, so pricing can be set on what the anticipated price of the fuels will be in the future. They are also governed by free market principles, so when there is a limited supply of them, the price of the fuels moves upward.

Fossil fuels, when consumed, can damage the environment in numerous ways.

One of the most devastating consequences of the transport and use of fossil fuels occurs when a spill happens. Oil spills, especially when they occur at sea, will frequently kill marine mammals. Seals and otters are at a high risk, while whales and dolphins experience severe negative impacts as well. Fossil fuels will contaminate food supplies, which increases the risk. Although the damage is often classified as short-term, the devastation can be so intense that it can cause long-term damage to certain regions as well.

Support networks create environmental damage as well.

For fossil fuels to be effective, a system of transportation and reserve networks must be built to support the power plant, refinery, or processing center. That means a coal-fired plant requires frequent deliveries of coal. Trains and trucks produce emissions because they also consume fossil fuels to generate power. Even the homes of workers consume fossil fuels and contribute emissions as well. That means every support network enhances the negative effects that fossil fuels have on our planet, especially if those who need the power live a good distance away from the power generation stations.

Mining and drilling activities also create environmental damage.

To obtain coal, we must be able to mine it. To obtain petroleum and natural gas, we must drill for it. Even shale oil or tar sands oil requires processing and collection activities. Mining may require trees to be cleared and topsoil to be removed. To reach certain wells or seams, entire regions may be blasted away, forever altering the local landscape and natural habitats. Rain can wash disturbed topsoil into streams, polluting local waterways, which hurts marine life.

Water pollution

Coal, oil, and gas development pose myriad threats to our waterways and groundwater. Coal mining operations wash acid runoff into streams, rivers, and lakes and dump vast quantities of unwanted rock and soil into streams. Oil spills and leaks during extraction or transport can pollute drinking water sources and jeopardize entire freshwater or ocean ecosystems. Fracking and its toxic fluids have also been found to contaminate drinking water.
