Fossil fuels, including coal, oil, and natural gas, have been the primary source of energy for the world since the Industrial Revolution. In 2023, fossil fuels accounted for 82% of the global energy mix, with oil and coal making up a third and a quarter of the world's energy consumption, respectively. While consumption patterns have shifted from solely coal to a combination of oil and gas, fossil fuel consumption has increased eight-fold since 1950 and doubled since 1980. This heavy reliance on fossil fuels has severe environmental, economic, and health consequences, with the burning of fossil fuels contributing to air pollution, climate change, and economic costs. As a result, there is a growing movement towards renewable energy sources, but the transition away from fossil fuels is challenging due to the continued dominance of fossil fuels in the energy sector.

What You'll Learn
Fossil fuels are the primary source of global electricity
Fossil fuels remain the primary source of global electricity, with coal, oil, and natural gas comprising around 80% of the global energy mix in 2023, according to the Energy Institute. This figure has remained relatively stable, with fossil fuels accounting for 84% of global energy consumption in 2019, according to BP's annual review. While electricity generation from renewable sources has grown at nearly triple the pace of fossil fuels since 2019, it has yet to surpass 40% of total electricity generation.
The dominance of fossil fuels varies across different regions. In Asia, for example, coal's share of the electricity generation mix has held flat at around 56%, while in Europe and North America, it has declined to around 14%. China, India, and Indonesia have been responsible for much of the growth in energy consumption, while the U.S. and Germany have posted the largest declines. China is also leading the global renewable energy race, accounting for 55% of all renewable energy additions in 2023.
In the United States, about 60% of electricity generation in 2023 came from fossil fuels, with coal, natural gas, and petroleum being the main sources. Nuclear energy accounted for about 19%, and renewable energy sources made up about 21%. The U.S. Energy Information Administration estimates that an additional 73.62 billion kWh of electricity was generated from small-scale solar photovoltaic systems in 2023. While the U.S. consumption of coal has halved in the last decade, it remains the world's third-largest consumer of coal.
Despite the negative global trend, the world still has a long way to go before renewable energy sources dominate the energy mix. The transition to clean energy has been slow, and the ever-increasing global energy demand has kept the share of energy coming from fossil fuels relatively unchanged. However, there is reason for optimism, with the IEA forecasting $2 trillion in investments in clean energy technologies and infrastructure in 2024, nearly double the amount invested in fossil fuels.

Oil and gas are growing quickly
Fossil fuel consumption has increased significantly over the past 50 years, with a roughly eightfold increase since 1950 and a doubling since 1980. While coal consumption is declining in many parts of the world, oil and gas are still growing quickly. In 2023, fossil fuels accounted for 82% of the global energy mix, with oil and coal accounting for a third and a quarter of global energy consumption, respectively. This demand was driven by a spike in energy needs, more than half of which came from the Global South, where energy demand is growing at twice the global rate.
The increase in fossil fuel consumption has had significant environmental and economic impacts. In 2018, air pollution from fossil fuels caused $2.9 trillion in health and economic costs, approximately $8 billion per day. The burning of fossil fuels is the primary source of unhealthy levels of fine particulate matter and nitrogen dioxide, which cause more than 13 million deaths worldwide each year.
Despite the negative consequences of fossil fuel consumption, the industry continues to grow due to several key factors. Firstly, there has been an increase in investment in oil extraction technologies, and the discovery of new oil reserves has driven production. Geopolitical events and economic conditions also play a role in shaping the market dynamics of the industry. For example, tensions in major oil-producing regions like the Middle East can lead to supply disruptions, creating opportunities for other producers, including the United States, to increase their market share.
Additionally, the oil and gas industry's capital discipline, increasing customer centricity, and investments in new technologies are contributing factors to its growth. For instance, the Permian Basin in the United States is experiencing rapid growth, with oil production increasing at an annual average of 485 kilobarrels per day, highlighting the region's importance in both domestic and international energy markets.
While there is a growing trend towards renewable energy sources, the world still has a long way to go before these sources dominate the energy mix. Clean energy sources are struggling to keep up with the ever-increasing global energy demand, and the transition to renewable energy sources has yet to start in earnest.

Fossil fuel consumption has increased eight-fold since 1950
Fossil fuels have been the dominant source of world energy production for the past century. Fossil fuel consumption has increased eight-fold since 1950, and roughly doubled since 1980. From 1950 to 2005, fossil fuels provided 85-93% of all energy production.
The burning of fossil fuels for energy began around the Industrial Revolution. However, the types of fuel we rely on have shifted from solely coal towards a combination of oil and gas. Today, coal consumption is falling in many parts of the world, but oil and gas are still growing quickly. In 2020, petroleum accounted for 31% of world energy use, coal for 27%, and natural gas for 25%.
The largest consumers of fossil fuels use more than ten times the amount of fossil energy than the smallest consumers. In 2023, fossil fuels accounted for 82% of the global energy mix, with oil and coal accounting for a third and a quarter of the world's energy consumption, respectively. This was driven by a spike in energy demand, more than half of which came from the Global South, where energy demand is growing at twice the global rate.
The transition away from fossil fuels is challenging, expensive, and complicated. However, renewable energy sources are available in all countries, and their potential is yet to be fully harnessed. The International Renewable Energy Agency (IRENA) estimates that 90% of the world's electricity can and should come from renewable sources by 2050. To achieve zero fossil fuel use by 2050, renewable energy production will need to increase by up to 6-8 fold, depending on energy demand.

Fossil fuels cause air pollution and health issues
Fossil fuels, including coal, oil, and natural gas, have been the world's primary energy source for centuries, with consumption increasing eightfold since 1950 and doubling since 1980. In 2023, they accounted for 82% of the global energy mix. However, this heavy reliance on fossil fuels comes at a significant cost to the environment and human health.
The burning of fossil fuels releases hazardous air pollutants, including sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury. These pollutants have severe health consequences, including asthma, cancer, heart disease, and
The combustion of fossil fuels also contributes to climate change by emitting greenhouse gases such as carbon dioxide (CO2). According to the Energy Institute, the increase in fossil fuel consumption in 2023 led to a record high of 40 gigatonnes of CO2 emissions. Climate change driven by these emissions poses additional health risks, particularly to children and the poor. It contributes to heat-related diseases, malnutrition, infectious diseases, and respiratory illnesses, further exacerbated by rising sea levels and more frequent flooding.
The transition from fossil fuels to renewable energy sources is crucial to address these pressing issues. Clean energy technologies offer not only climate benefits but also immediate health gains, reducing the number of premature deaths attributed to air pollution. While the upfront cost of investing in renewable infrastructure can be high, the long-term economic and social benefits are significant, including new job creation and improved energy security.
In summary, the world's current dependence on fossil fuels has led to severe air pollution and health issues, impacting millions of lives and costing trillions of dollars. To safeguard public health and build a more sustainable future, a swift and decisive shift towards renewable and low-carbon energy sources is imperative.

The transition to renewable energy is expensive
Fossil fuels—coal, oil, and natural gas—comprised 82% of the global energy mix in 2023, according to the Energy Institute's latest report. Oil and coal accounted for a third and a quarter of the world's energy consumption, respectively. Fossil fuel consumption has increased significantly over the past half-century, roughly doubling since 1980. About 6 billion people, or 80% of the global population, live in countries that are net importers of fossil fuels and are therefore vulnerable to geopolitical shocks and crises.
Transitioning to renewable energy sources is critical to addressing climate change and air pollution, and it is generally acknowledged that this transition will come with significant costs. However, the notion that the transition to renewable energy is expensive is more nuanced than it initially appears. While upfront costs can be daunting, renewable energy is, in fact, the cheapest power option in most parts of the world today.
The International Renewable Energy Agency (IRENA) estimates that $4.5 trillion per year needs to be invested in renewable energy infrastructure and technology until 2030 to reach net-zero emissions by 2050. While this figure may seem staggering, it is important to consider the potential savings and economic growth that renewable energy can bring. For example, the reduction of pollution and climate impacts alone could save the world up to $4.2 trillion per year by 2030. Additionally, renewable energy sources can drive inclusive economic growth, create new jobs, and alleviate poverty.
Furthermore, the cost of renewable energy has been dropping over time. In 2017, Professor Heal estimated that it would cost $3.97 trillion to transition from fossil fuels to renewable energy, net of fuel cost savings. However, with the decreasing cost of renewable energy, his estimation for the annual cost of transitioning from now until 2050 stands at $179 billion. This is a fraction of the cost that the United States currently spends annually, which is roughly $50 billion.
While transitioning to renewable energy may require significant upfront investments, it is important to consider the long-term benefits and potential cost savings. Additionally, the transition to renewable energy should not be viewed as a cost but rather as an investment in the future of our planet and the well-being of generations to come.
