Access to affordable and reliable energy from these hydrocarbons increase economic growth by industrial activities, investments, and enhancing productivity across various sectors of the economy. Hence, one of the important advantages of fossil fuels.
Disadvantages Of Fossil Fuels
Now the we have seen the advantages of fossil fuels, let’s discuss that what are the disadvantages of fossil fuels –
Create Environmental Pollution
Burning these combustible fuels releases pollutants such as carbon dioxide (CO2), sulfur dioxide (SO2), nitrogen oxides (NOx) into the atmosphere, which contribute to air pollution, acid rain, and smog formation.
Reported by Amnesty International, the climate justice researcher of the same Candy Ofime has stated that, we are headed for even more climate disaster if we continue to grow the world’s supply of coal until 2030 and global production of oil and gas until at least 2050.
Environmental pollution is one of the two main disadvantages of fossil fuels, the other one is their non-renewable nature.
They Are Non-Renewable
Fossil fuels are non-renewable resources, which means they cannot be replenished within a human time frame once they are depleted.
Effect On Climate Change
One of the disadvantages of fossil fuels is their effect on climate change. Fossil fuel combustion is a major contributor to climate change, as it releases large amounts of greenhouse gasses (primarily CO2) into the atmosphere, causing global warming.
As recently reported by The Guardian, due to pollution from fossil fuels, the home of walruses, seals, and polar bears may consist mostly of water for months as early as 2035.
Disruption Of Land
Land disruption is also a major issue during fossil fuel extraction activities. Mining and drilling, require large land areas and can lead to habitat destruction, soil erosion, etc.
External Impact And Subsidies
Another disadvantages of fossil fuels is that their production and consumption are often subsidized by governments, leading to market distortions and inefficient allocation of resources.
Additionally, the social and environmental costs associated with these hydrocarbons known as externalities are sometimes not fully accounted for in market prices.
Types of Fossil Fuels
Fossil fuels are primarily categorized into three main types –
- Coal
- Petroleum (Oil)
- Natural Gas
Coal
Coal is a combustible sedimentary rock mainly made up of carbon, along with varying amounts of other elements such as hydrogen, sulfur, oxygen, and nitrogen.
What makes coal truly remarkable is its origin: it is formed from the remains of ancient plants that underwent transformation under heat and pressure over millions of years.
Coal serves as a major part of the advantages of fossil fuels. From illuminating our homes to fueling power plants for electricity generation, heating, steam generation, industrial processes, etc. coal occupies a key position.
According to Aljazeera, the International Energy Agency (IEA) has stated that in 2023, the demand for coal is seen rising by 1.4 percent, topping 8.5 billion tons for the first time.
The main drivers being India and China, where the usage is expected to rise by 8% in India and 5% in China as a result of growing electrical demand.
Petroleum (Oil)
Petroleum, commonly known as oil, is a naturally occurring liquid hydrocarbon mixture found under the Earth’s surface. Hydrocarbon present in petroleum is a vast class of chemicals composed of both carbon and hydrogen.
This carbon-based fuel is formed from the decayed organic matter of ancient marine organisms, such as algae and plankton, which collected in sedimentary rock layers over millions of years.
From the use of Liquified petroleum gas in gas fireplaces, cooktops, and barbecue grills, to transportation fuel, facilitating road construction, and serving as lubricant, the advantages of fossil fuels like petroleum fulfills a variety of essential roles in modern society.
Natural Gas
The main hydrocarbon gas in natural gas is methane (CH4), however there is also small amounts of ethane, propane, butane, and other gasses.
This combustible fuel is formed from the decomposition of organic matter, similar to oil, and is typically found in underground reservoirs.
There is an advantage of switching to natural gas as a fuel instead of oil is that natural gas is a much cleaner fossil fuel.
Compared to burning coal or petroleum products, using natural gas produces less emissions of carbon dioxide (CO2).
The advantages of fossil fuels are not complete without natural gas. It is extracted through drilling and is commonly used for heating, electricity generation, cooking, and transportation.
Why Are Fossil fuels Important
Fossil fuels play a significant role in global energy systems and economies due to several important reasons.
Other than the diverse advantages of fossil fuels, for cooking, transportation, to industrial processes and chemical production, the 3 reasons why fossil fuels are important are –
Energy Availability and Reliability
Fossil fuels give us a reliable and abundant source of energy that meets a significant portion of global energy demand.
The advantages of fossil fuels include providing power in homes, businesses, industries, and transportation systems, keeping in check the continuous functioning of economies and societies worldwide.
Economic Significance
The advantages of fossil fuels has a crucial role in global economies, contributing to job creation, revenue generation, and economic growth.
From extraction and refining to distribution and consumption, these hydrocarbons serve a wide range of industries and sectors, increasing investment, trade, and prosperity.
Infrastructure and Versatility
One of the great advantages of fossil fuels is that they have given us large infrastructure networks which are built over decades to extract, transport, refine, and distribute them efficiently.
This infrastructure, including oil and gas wells, pipelines, refineries, and power plants, allows the delivery of energy to consumers in various forms and applications, which support diverse energy needs and technological advancements.
Now that we have seen the advantages, disadvantages, types and importance of these natural hydrocarbons, let’s learn how fossil fuels are actually formed.
How Are Fossil Fuels Formed
Here is a step wise procedure of how fossil fuels are formed –
- So the formation of fossil fuels begins with the collection of organic matter, derived from ancient plants and microscopic marine organisms, such as algae and plankton.
- When these organisms die, their remains settle in oxygen-poor environments, such as swamps, rivers, or deep ocean sediments, which prevent their complete decomposition by bacteria and other organisms.
- As the organic matter becomes buried under layers of sediment, this increases the pressure from the layers which is compressing the organic material.
- Additionally, the Earth’s heat from within and the natural decay of radioactive elements within the Earth increase temperatures from within as well.
- Under the pressure and heat, the organic matter undergoes biochemical and physical changes. Initially, the organic material is transformed into peat, which is an earlier form of coal.
- Over millions of years, the peat is buried deeper and exposed to increasing pressure and temperature.
- As a result, the peat undergoes further chemical and physical changes, compacting and solidifying into different types of coal.
- Now in marine environments, the buried organic matter undergoes a different process of transformation.
- As layers of sediment collect over time, the organic material is exposed to heat and pressure, which lead to the formation of petroleum and natural gas.
- Once trapped in underground reservoirs, fossil fuels can be extracted through drilling techniques, such as drilling wells into the reservoir rocks.
Conclusion
Fossil fuels provide reliable and versatile energy for electricity, transportation, and industry, supported by extensive infrastructure and economic significance. The undeniable advantages of fossil fuels have driven economic growth, contributing to energy security for countries with abundant reserves. However, their use raises environmental concerns highlighting the need to shift to cleaner and more sustainable energy sources.
