Fossil fuels, including coal, oil, and gas, have been the world's primary energy source, accounting for 79% of energy production. Their affordability has contributed to their dominance, but they have significant negative side effects, including harmful emissions and air pollution, which lead to severe health issues and environmental degradation. Alternatives like renewable energy sources and nuclear power offer cleaner and safer options but have faced challenges with consistent power supply and infrastructure demands. As renewable technologies advance, their costs are decreasing, making them increasingly competitive with fossil fuels. However, the transition to cleaner energy sources requires addressing energy storage, supply stability, and infrastructure development to meet the world's energy demands.

What You'll Learn
Fossil fuels are abundant and easy to find
Fossil fuels are generally concentrated in giant deposits, making them abundant and cheap. Their price is often marked up only slightly above the cost of extraction and transportation to the point of consumption. This has resulted in energy prices that are incredibly low compared to any other time in human history.
The world has become accustomed to cheap energy, with fossil fuels powering the planet for the last 250 years. Over the last two centuries, the vast reserves of coal, oil, and gas meant that there was always enough energy to meet demand. This abundance of fossil fuels allowed energy suppliers to keep up with demand, even during spikes, and maintain sufficient buffer stocks.
The infrastructure for fossil fuels is already in place, making them a reliable and convenient source of energy. For instance, coal and oil are energy-dense and stable, making them easy to transport to their point of use. In contrast, renewable energy sources are often less convenient, as they may require battery storage and grid upgrades.
However, it is important to note that the true cost of fossil fuels is much greater than their market price, as they have significant environmental and health impacts that are not reflected in their cost. As fossil fuel supplies dwindle, the cost of extraction from deeper wells and mines in more hostile environments will further increase the expense of fossil fuels.

They have been the main energy source for decades, so the infrastructure is already in place
Fossil fuels have been the primary energy source for over a century, and in that time, the infrastructure to support their use has been developed and optimised. This infrastructure includes pipelines, refineries, power plants, and oil rigs. The long-standing and widespread use of fossil fuels has allowed energy suppliers to create a system where supply can keep up with demand, even when demand spikes. This has resulted in a cheap and reliable energy source.
The infrastructure in place for fossil fuels has been refined over many years, and the technology used to harness them has advanced significantly. Techniques such as hydraulic fracturing (fracking) and horizontal drilling have made accessing fuel reserves easier and more efficient. This efficiency helps to keep costs low. Additionally, the energy industry has become highly centralised, with giant utility corporations extracting, processing, and supplying fossil fuels, further optimising the process and driving down costs.
The abundance of fossil fuels in the past has also contributed to their affordability. The vast reserves of coal, oil, and gas discovered over the last two centuries meant that there was always enough energy to meet demand. This abundance, combined with efficient infrastructure, has kept prices low for consumers. However, this dynamic is changing as fossil fuel supplies dwindle, making new deposits more challenging and costly to find.
The infrastructure supporting fossil fuels has become so entrenched that it has shaped the way energy is generated and distributed. Fossil fuels' energy density and stability have made them convenient to transport and use, solidifying their position as a cheap and readily available energy source. However, this convenience comes at a cost. Fossil fuels are non-renewable and unsustainable, contributing to climate change and causing harm to the environment and human health.
While fossil fuels have been cheap and reliable due to their established infrastructure, the tide is turning. The environmental and health costs of fossil fuels are becoming more apparent, and their true cost to society is much higher than their market price. Renewable energy sources, on the other hand, are becoming more efficient and affordable, offering a sustainable alternative that is better for the planet and human wellbeing.

They are dependable and not weather-dependent
Fossil fuels are dependable and not weather-dependent. This is one of the reasons why they are cheap. For much of the last 50 years, the way energy has been generated and distributed has changed very little. Fossil fuels have been powering the world for decades, making them dependable since the infrastructure is already in place for their continued use. Most of our infrastructure, including pipelines, refineries, power plants, and oil rigs, is built around fossil fuels.
The world has become accustomed to energy being amazingly cheap compared to any time in human history. Fossil fuels have been abundant, and their price has been set at some markup on the cost of getting them out of the ground and to the point of consumption. Fossil fuels are energy-dense and stable, making them convenient to transport to their point of use. Even natural gas can be piped relatively easily or transported by LNG tanker.
The world is moving towards green energy, but this does not mean that we can completely throw away fossil fuels. Fossil fuels are the most widely used energy sources globally and account for ~80% of total energy consumption. They were the fundamental drivers of the Industrial Revolution. Fossil fuels have been used for over 100 years, allowing plenty of time for technological advancement.
While fossil fuels have negative impacts and contribute to human-induced climate change and global warming, they have also provided tremendous benefits to society. Fossil fuels have lifted over 660 million people in China out of poverty. In addition, as electricity consumption increases due to fossil fuels, the infant mortality rate decreases, and access to improved drinking water sources increases.

They are energy-dense, making them convenient to transport
Fossil fuels are energy-dense, making them convenient to transport. This is particularly important in the transportation sector, where a vehicle needs to carry its fuel as it travels, so the weight and volume of that fuel are key.
Liquid fuels made from oil can be pumped, which opened up new technologies, especially in transportation. For example, gasoline is the dominant transportation fuel in the United States, followed by distillate fuels (mostly diesel fuel) and jet fuel. In 2023, petroleum products accounted for about 89% of the total US transportation sector energy use.
The energy density of fossil fuels means that a smaller weight or volume of fuel is needed to do the job. For instance, coal has three times the energy density by weight of dry wood. Pound for pound, gasoline or diesel fuel contains about 40 times as much energy as a state-of-the-art battery.
Other fuels like compressed propane, ethanol, and methanol offer energy densities per unit volume that are less than gasoline and diesel, and energy densities per unit weight that are less than or equal to that of gasoline.
However, it is important to note that the advantages of fossil fuels come with a devastating downside. The release of carbon dioxide (CO2) from burning fossil fuels is warming the planet faster than anything seen in the geological record.

As supplies dwindle, the cost of finding new deposits goes up
Fossil fuels have been the world's primary energy source for decades, and their infrastructure is well-developed and in place. This has made them a cheap and reliable source of energy. However, fossil fuels are non-renewable, and as their reserves deplete, the cost of finding new deposits will inevitably increase.
Fossil fuels, formed from decomposed organic matter, take millions of years to form. As we continue to use fossil fuel reserves, less will be available for the future. This is in contrast to renewable energy sources, which do not deplete our fuel reserves. For example, using solar panels to harness solar power does not diminish the sun's energy.
The law of supply and demand dictates that as supplies of fossil fuels dwindle, prices will increase. This is already being observed in certain contexts, such as with the UK's North Sea oil and gas fields, Mexico's Canterell oil field, and Kuwait's Barghan oil field. As these finite resources become scarcer, the cost of finding new deposits will rise, leading to long-term economic challenges.
The social cost of fossil fuels, including their impact on climate change, human health, and the environment, is also significant. According to research, the true cost of fossil fuels is much greater than the price we pay at the pumps or on our utility bills. These externalities, such as the health, climate, and environmental problems linked to emissions, are not typically factored into the price of fossil fuels. As a result, society has become accustomed to having an abundant and cheap energy supply, but this dynamic will change as fossil fuel depletion impacts input availability.
