Fossil fuels are reliable, cheap, and ingrained in our infrastructure
Fossil fuels have been the primary energy source for over 150 years, and our infrastructure is built to use them. They have been instrumental in shaping the modern world, with their usage dating back to the 18th century. The discovery of coal and its widespread adoption during the Industrial Revolution marked a transformative moment in history, allowing rapid industrialization in countries like the UK, US, and Europe. This was followed by the discovery of oil, which revolutionized transportation and the automotive industry.
The accessibility, energy density, and affordability of coal, oil, and natural gas have propelled economic growth and development on an unprecedented scale. Fossil fuels are reliable and have helped society advance in ways that would not have been possible without them. They are energy-dense, meaning a smaller volume of fuel is needed to do the job. Liquid fuels made from oil, for example, can be pumped, which opened up new technologies, especially in transportation.
However, the advancement brought about by fossil fuels has come at a devastating environmental cost. With climate change accelerating, it is impossible to ignore the need to shift away from fossil fuels and towards renewable energy sources. Yet, this is no simple task. Fossil fuels are ingrained in our infrastructure, and transitioning to renewable energy sources comes with a hefty price tag. For some countries, this transition may not be feasible.
In addition, there are workforce implications, with a vast number of jobs depending directly or indirectly on the continued use of fossil fuels. There are also technological limitations, as existing electrical grids need to be revamped to integrate renewable energy sources. The intermittent nature of renewables like solar and wind also demands innovative energy storage solutions to ensure an on-demand supply.
Furthermore, fossil fuel industries have a powerful influence in many economies and may resist efforts to transition away from them to protect profits. Political hurdles also exist, with differing views among countries and leaders on the urgency and extent of the climate crisis. Policymakers often focus on short-term issues, and transitioning away from fossil fuels requires careful planning and foresight to avoid economic disruption.
Despite these challenges, the need to transition away from fossil fuels is now widely recognized, and progress has been made, especially in the adoption of renewable energy in the transport and energy sectors. However, the pace of change must accelerate to meet global net-zero ambitions.

Historical data suggests that demand will enable producers to access new deposits
Fossil fuels have been a catalyst for human advancement. For almost three centuries, fossil fuels have served as the lifeblood of industrialization, transportation, and energy production, helping to transform societies and raise living standards across the globe. The discovery of coal and its widespread adoption during the Industrial Revolution marked a transformative moment in history. Society's energy needs changed forever as coal-powered steam engines fueled factories, railways, and ships, setting the stage for rapid industrialization in countries such as the UK, the US, and across Europe. In the early 20th century, the discovery of oil as a versatile energy source revolutionized transportation and gave rise to the automotive industry.
However, this advancement has come at a devastating cost to the environment. With climate change accelerating, it is impossible to ignore the need to shift away from fossil fuels and transition towards using renewable energy sources. The world needs to cut its greenhouse gas emissions quickly. While there has been remarkable progress, especially in the adoption of renewable energy in the transport and energy sectors, the pace of change is still not fast enough to meet global net-zero ambitions.
Historical data suggests that as demand grows, producers will be able to access new deposits. An analysis by MIT and University of Chicago researchers concludes that market forces alone won't reduce the world's reliance on fossil fuels for energy. As Knittel states, "It's true that there's a finite amount of oil and natural gas in the ground, so every barrel of oil we take out means there's one less barrel of oil left. But each year we get better at finding new sources or at taking existing fossil fuels out of the ground." Data from the BP Statistical Review of World Energy shows that proven reserves (economically recoverable deposits) for coal, oil, and natural gas have grown at least as fast as consumption. Technological advances constantly make new deposits economically accessible and extractable.
While the transition to renewable energy sources is underway, it is dependent on a complex web of factors, including economic, political, technological, and social considerations. Investment in renewables and lower-carbon technologies is growing but not at the level required to enable a complete energy transition. At the same time, investments in fossil fuel infrastructure continue, locking in emissions for decades.

Political hurdles and differing views on the climate crisis hinder global unanimity
Political hurdles and differing views on the climate crisis are significant obstacles to achieving global unanimity in the transition away from fossil fuels. While there is a growing recognition of the need to address climate change and promote sustainability, the pace of change is not keeping up with the urgency of the situation.
One of the key challenges is the differing views among countries and leaders regarding the severity and immediacy of the climate crisis. Some sceptics believe that the scientific consensus might be overstated or that risks can be addressed at a later stage, delaying the implementation of necessary policies and measures. This lack of global unanimity hinders coordinated action and slows down progress.
Additionally, the transition away from fossil fuels is complex and politically challenging. Policymakers often prioritise short-term issues such as inflation, unemployment, and re-election over long-term environmental goals. The powerful influence of the fossil fuel industry on economies and the resistance to protect profits further complicate the transition. Historical data suggests that as demand grows, new technologies will enable producers to tap into previously inaccessible fossil fuel deposits, making them the cheapest energy option.
The transition to renewable energy sources carries a hefty price tag, requiring careful planning and foresight to avoid economic disruption. This is especially true for developing countries that need to provide modern energy access to their citizens while following a cleaner path than developed nations. The challenge is magnified by the need to provide both cleaner and more energy, and the lack of feasible alternatives in certain sectors, such as aviation, where the energy density of jet fuel is yet to be matched by renewable options.
Furthermore, workforce implications play a role in the transition. A large number of jobs, both directly and indirectly related to the fossil fuel industry, depend on its continued use. Transitioning away requires planning to ensure a just transition for affected workers and communities. Technological limitations and the need for restructuring energy infrastructure also pose significant challenges. While investment in renewables and lower-carbon technologies is growing, it is not yet at the level required to achieve a complete energy transition.

The aviation industry still relies on the unmatched energy density of jet fuel
Fossil fuels have been the world's primary energy source for over 150 years, and their use has become deeply ingrained in our daily lives. While there is a growing recognition of the need to transition to renewable energy sources, this process is challenging due to the entrenched infrastructure and the powerful influence of the fossil fuel industry.
The aviation industry is a notable example of a sector that still heavily relies on fossil fuels, specifically jet fuel or aviation turbine fuel (ATF). Jet fuel is designed for aircraft powered by gas-turbine engines and is the most widely used fuel in commercial aviation. Its key advantage lies in its energy density, which refers to the amount of energy per unit weight or volume. Jet fuel's high energy density makes it extremely efficient for powering aircraft, as a smaller amount of fuel can generate significant power.
The energy density of jet fuel is unmatched by current alternatives, making it challenging for the aviation industry to transition away from fossil fuels. While Sustainable Aviation Fuel (SAF), including aviation biofuel and synthetic fuel, has gained traction, it still accounts for a minuscule proportion of total jet fuel usage. SAF is produced from sources like used cooking oil, agricultural residues, and other waste materials, offering a more environmentally friendly option. However, the production and adoption of SAF face several hurdles, including economic constraints, infrastructure limitations, and a lack of comprehensive industry roadmaps.
Moreover, jet fuel is widely available worldwide, whereas alternative fuels like avgas are only accessible in a limited number of countries. The accessibility and established infrastructure of jet fuel distribution networks further reinforce the aviation industry's reliance on this fossil fuel. Additionally, jet fuel has specific performance characteristics that are critical for aviation, such as a high flash point, low viscosity at low temperatures, and chemical stability when heated to high temperatures.
While the aviation industry recognizes the need to reduce emissions, the unique performance requirements and the absence of readily available alternatives to jet fuel present significant challenges in the transition away from fossil fuels. Nevertheless, initiatives like the collaboration between United Airlines and World Energy demonstrate a commitment to exploring sustainable options. However, to achieve a substantial shift, the industry requires more extensive adoption of SAF, innovative technologies, and supportive policies.
