Fossil fuel consumption trends
Fossil fuels, including coal, oil, and natural gas, have been the primary source of energy for over 150 years. They have played a crucial role in industrialization and global energy systems, but their impact on climate change and human health has led to a growing need to transition to cleaner energy sources.
Historical Consumption Trends
The consumption of fossil fuels has fluctuated significantly over the past few centuries. The burning of fossil fuels began around the Industrial Revolution, and since then, the types of fuel used and the total consumption have evolved. Initially, coal was the primary source of energy, but over time, the focus shifted to a combination of coal, oil, and natural gas.
Recent Consumption Patterns
According to recent data, fossil fuel consumption has increased significantly in the past 50 years, approximately eightfold since 1950 and doubling since 1980. While coal consumption is declining in many regions, oil and natural gas consumption continue to grow rapidly. In 2020, oil was the largest contributor to carbon emissions in the United States, closely followed by natural gas.
Country-Level Consumption
When examining fossil fuel consumption by country, it is important to consider both population size and per capita consumption. Some countries consume significantly more fossil fuels than others, and larger populations can skew the data. The United States, for example, consumed about 22% of the world's natural gas in 2020, with natural gas supplying one-third of the country's energy consumption.
Transition to Alternative Energy Sources
The negative impacts of fossil fuels have spurred the exploration of alternative energy sources. Low-carbon sources such as hydropower, biomass, wind, geothermal, and solar energy and nuclear power offer promising alternatives to fossil fuels. Additionally, carbon capture and storage (CCS) technologies aim to mitigate the effects of carbon dioxide emissions, with 26 commercial CCS plants worldwide in 2020. However, the continued burning of fossil fuels remains a concern, and a rapid transition to cleaner energy sources is necessary to combat climate change effectively.

The impact of fossil fuels on climate change
Fossil fuels have been powering economies for over 150 years, and currently supply about 80% of the world's energy. The burning of fossil fuels for energy began around the Industrial Revolution, and fossil fuel consumption has increased significantly over the past few centuries. In 2020, oil was the largest source of US energy-related carbon emissions, with natural gas close behind. The three fossil fuels contribute varying levels of emissions across sectors.
The burning of fossil fuels releases large amounts of carbon dioxide and other greenhouse gases into the atmosphere. Greenhouse gases trap heat in the atmosphere, causing global warming and climate change. The average global temperature has already increased by 1°C, and global temperatures passed the critical 1.5°C milestone for the first time in 2024. Warming above 1.5°C risks further sea level rise, extreme weather, biodiversity loss, species extinction, food scarcity, and worsening health and poverty for millions of people worldwide.
Coal combustion produces a variety of air pollutants that harm human and environmental health, such as sulfur dioxide, nitrogen oxides, mercury, and particulate matter. Coal ash is another harmful coal waste product that is difficult to recycle and can seep into waterways, polluting them. Oil and gas wells and transport and processing facilities expose millions of people to toxic air pollution, including benzene and formaldehyde.
To mitigate the impact of fossil fuels on climate change, a transition to clean and renewable energy sources is necessary. Hydropower, biomass, wind, geothermal, and solar energy are reliable sources of renewable energy and have been a growing part of the energy mix in many countries. Nuclear energy is another zero-carbon alternative, but it is expensive and leaves behind long-lasting radioactive waste. Additionally, carbon capture and storage (CCS) technologies can be used to collect and inject carbon emitted by the fossil fuel sector back into the earth. However, increasing carbon capture and storage does not mean industries should continue burning fossil fuels unabated. As low-carbon sources of energy become readily available, the world needs to rapidly transition away from fossil fuels to mitigate their impact on climate change.

The shift from coal to oil and gas
Fossil fuels, including coal, oil, and natural gas, have been the world's primary energy source for over 150 years. They have played a dominant role in global energy systems, powering economies and driving technological, social, and economic progress. However, the burning of fossil fuels releases carbon dioxide (CO2) and other greenhouse gases, making them the largest driver of global climate change. As a result, there is a growing need and effort to transition from fossil fuels to renewable energy sources.
The transition was also driven by innovations in oil and gas-related technologies, which made them more competitive with coal. Consumers replaced coal with hydrocarbon alternatives, as they provided diversified energy options and increased convenience. This shift away from coal towards hydrocarbons (oil and gas) was particularly notable in Western Europe and the United States, where coal used to be the dominant fuel.
Today, coal consumption is declining in many parts of the world, while oil and gas consumption continue to grow. Natural gas, in particular, is projected to meet an increasing share of energy demand, especially in the industrial sector. However, the continued reliance on fossil fuels and the increasing consumption of oil and gas impede progress in limiting global warming and climate change. As renewable energy sources become more accessible and affordable, the transition away from fossil fuels is gaining momentum, as evident in agreements like the Glasgow Climate Pact.
While solar and wind energy are becoming the cheapest and most scalable sources of new energy, the challenge lies in ensuring that the energy system storage is not compromised during the transition to renewables. Additionally, the total amount of renewable energy available is still lower than the increasing global energy demand. Thus, navigating the shift from fossil fuels to renewable alternatives requires a comprehensive approach that addresses energy storage, infrastructure, and consumption patterns.

Alternatives to fossil fuels
Fossil fuel consumption has increased significantly over the past half-century, with emissions from fossil fuels continuing to rise. In 2022 and 2023, there were record increases in carbon dioxide emissions from fossil fuels. Fossil fuels are the dominant energy source globally, currently supplying about 80% of the world's energy.
However, there is a growing movement to reduce our reliance on fossil fuels due to their environmental and geopolitical risks. Renewable energy sources are becoming increasingly affordable and efficient, and they are not subject to the same price volatility as some fossil fuels. While the switch to renewables will not be easy and will require significant investment in new technologies and infrastructure, it is important to rapidly transition away from fossil fuels as low-carbon sources of energy become readily available.
- Renewable energy sources: Renewable energy sources are available in abundance all around us, provided by the sun, wind, water, waste, and heat from the Earth. They emit little to no greenhouse gases or pollutants into the air and are replenished by nature. Renewable energy sources are also the cheapest power option in most parts of the world today, with prices for renewable energy technologies dropping rapidly. Every dollar of investment in renewables creates three times more jobs than in the fossil fuel industry.
- Nuclear power: Nuclear energy is a zero-carbon alternative to fossil fuels. However, it is expensive and leaves behind long-lasting radioactive waste that is dangerous and costly to transport and store for disposal. Nuclear energy is also not considered a renewable source of energy as it relies on fission reactions in materials like plutonium or uranium.
- Hydrogen: Hydrogen is particularly considered an alternative fuel for heavy transport such as ships, trucks, and even aircraft. However, it relies on existing supplies of energy to be created.
- Biomass: Biomass is biological material that is either living or decaying, including wood, plant, forest residues, and compost material. Some crops such as rapeseed are specifically grown as biofuels. Many coal-fired plants are being converted to biomass to reduce emissions. However, burning biomass still produces greenhouse gases.
- Geothermal energy: Geothermal power is harnessed from the Earth's natural sources of heat, led by volcanic activity. It is the source of 30% of all electricity power in Iceland, which taps into thermal springs heated by molten rock lying thousands of meters below the surface. However, geothermal energy is restricted to areas with volcanic sources.
While these alternatives to fossil fuels offer promising solutions, it is important to note that some of them, such as wind and solar energy, are dependent on variable natural factors like sunlight and wind patterns, which can impact their reliability.

Fossil fuel advertising
Fossil fuels, including coal, oil, and natural gas, have been the primary source of energy for over 150 years, currently supplying about 80% of the world's energy. The burning of fossil fuels releases greenhouse gases, such as carbon dioxide, into the atmosphere, contributing to global climate change. While there has been a shift from coal towards oil and gas, fossil fuel consumption has increased significantly over the past decades, with emissions reaching record levels in 2023.
Despite the urgent need to transition to renewable energy sources, fossil fuel companies continue to play a dominant role in global energy systems. These companies have come under scrutiny for their advertising practices, with allegations of spreading misinformation and greenwashing. Greenwashing is a tactic used to mislead the public into perceiving a company as environmentally conscious when it is not. For example, in 2021, ClientEarth successfully challenged BP's renewable energy advertisement, as 96% of the company's spend was on oil and gas. Fossil fuel companies also use advertising to promote false solutions to the climate crisis, such as fossil gas, bioenergy, and carbon capture and storage (CCS).
In addition to traditional advertising campaigns, fossil fuel companies have become some of the biggest spenders on Google ads, targeting climate-related search terms. A study found that one in five ads on 78 climate-related search terms were placed by firms with interests in fossil fuels. These ads are designed to look like search results, making it difficult for users to distinguish between paid advertisements and organic search results. Fossil fuel companies also use lobbying, doubt-inducing media strategies, and brand building to deflect corporate responsibility and delay much-needed climate action.
There have been growing calls for a complete ban on fossil fuel advertising, similar to the ban on tobacco advertising. A ban on tobacco advertising and sponsorship in the EU has led to a decline in cigarette usage, and it is argued that a similar approach could reduce the influence of fossil fuel companies and address the climate crisis. However, some argue that regulating corporate advertising may be a more feasible approach, as a complete ban on fossil fuel advertising may face legal and implementation challenges.
As the world transitions to low-carbon sources of energy, it is crucial to address the role of fossil fuel advertising in shaping public perception and influencing policy. By promoting misleading information and delaying climate action, fossil fuel advertising contributes to the continued reliance on fossil fuels and impedes progress towards a sustainable future.
