What You'll Learn
Fossil fuels will still dominate energy use in 2050
Despite the growing number of countries pledging to achieve net-zero emissions over the coming decades, fossil fuels will still dominate energy use in 2050. This is due to the massive investments that have already been made in the fossil fuel industry, as well as the superior energy intensity and reliability of fossil fuels. In 2022, about $7 trillion was spent on subsidizing the fossil fuel industry, while only around $4.5 trillion per year is needed to be invested in renewable energy sources until 2030 to reach net-zero emissions by 2050.
The transition to renewable energy sources requires substantial investment in new technologies and infrastructure. While renewable energy sources are available in abundance and are naturally replenished, emitting little to no greenhouse gases or pollutants into the air, they currently make up a small proportion of the world's energy production. Fossil fuels still account for more than 80% of global energy production, and while this is expected to decline, it will still dominate energy use in 2050.
According to research by McKinsey, fossil fuels will make up 38% of global power generation in 2050, down from 66% when the research was published in 2016. This prediction is based on the assumption that there will be no major disruptions in the production or use of energy, and that global energy demand will continue to grow, albeit at a slower rate of about 0.7% per year through 2050.
To achieve net-zero emissions by 2050, emissions need to be reduced by almost half by 2030. This will require a rapid deployment of available technologies, as well as the widespread use of new technologies that are not yet on the market. Fossil fuel subsidy phase-outs, carbon pricing, and other market reforms can also help to encourage the transition to renewable energy sources.
While it is predicted that fossil fuels will still dominate energy use in 2050, it is important to note that this prediction is based on current trends and assumptions, and does not take into account potential future disruptions or technological advancements. Concerted global action to reduce greenhouse gas emissions and technological innovations could change these trends, and it is important for governments and businesses to prioritize investments in renewable energy sources and energy efficiency to mitigate environmental harm.

Global energy demand will continue to grow
Despite the overall growth in energy demand, the demand for fossil fuels is expected to decline. According to the International Energy Agency (IEA), global energy demand in 2050 will be around 8% smaller than it is today, even as the world economy and population continue to expand. This indicates a shift towards cleaner, more sustainable energy sources.
To achieve net-zero emissions by 2050, a rapid transition to renewable energy sources is necessary. The IEA emphasizes the need for further deployment of existing technologies and the development of new ones. Fossil fuel subsidy phase-outs, carbon pricing, and market reforms can also encourage the adoption of cleaner energy sources. Additionally, investments in renewable energy infrastructure and technology are crucial. While the upfront costs may be high, the environmental and economic benefits, including reduced pollution and improved energy security, will pay off in the long run.
The transition to renewable energy also presents opportunities for economic growth and job creation. The renewable energy sector offers new jobs in different locations and sectors, which can help mitigate the job losses in the fossil fuel industry. Furthermore, renewable energy sources are available in all countries, reducing import dependency and providing a more stable and affordable energy supply.
While global energy demand will continue to grow, the energy landscape is expected to undergo significant changes by 2050. The decline in fossil fuel demand and the rise of renewable energy sources will play a crucial role in mitigating climate change and creating a more sustainable future.

Fossil fuel phase-out
Fossil fuels, including coal, oil, and natural gas, are primarily burned to generate energy, releasing greenhouse gases like CO2 and contributing significantly to global warming. Phasing out fossil fuels is essential to reducing air pollution, strengthening energy independence, and mitigating the worst impacts of climate change. According to the International Energy Agency, the phase-out of fossil fuels needs to "move four times faster" to align with the goals of the Paris Agreement.
To achieve a fossil fuel phase-out, countries are employing various strategies. Many nations are shutting down coal-fired power stations, transitioning to electric vehicles, and setting dates to stop selling petrol and diesel vehicles. Additionally, alternatives to fossil fuels, such as electrification, green hydrogen, biofuel, and renewable energy sources, are being adopted. However, the transition away from fossil fuels must be just and equitable, addressing the needs of fossil fuel-dependent workers and communities.
While challenges and uncertainties remain, the solutions to achieve a significant phase-out of fossil fuels by 2050 are currently available. Strong policies, increased investment in clean energy technologies, and a rapid decline in the production and use of fossil fuels are crucial to achieving this goal.

Global energy demand in 2050 will be 8% smaller than today
Global energy demand in 2050 is projected to be 8% smaller than it is today. This reduction in energy demand is a result of digitization, slower population and economic growth, greater efficiency, a decline in European and North American demand, and the global economic shift toward services, which use less energy than the production of goods.
Despite this projected decrease in global energy demand, governments plan to produce 110% more fossil fuels by 2030 than would be consistent with limiting warming to 1.5°C. This is due to the massive investments that have already been made in fossil fuels and their superior energy intensity and reliability. Fossil fuels still account for more than 80% of global energy production, and global carbon dioxide emissions, of which almost 90% are attributed to fossil fuels, rose to record highs in 2021-2022.
To avoid the worst impacts of climate change, emissions must be reduced by almost half by 2030 and reach net-zero by 2050. This will require a rapid deployment of available technologies as well as widespread use of new technologies, such as carbon capture and storage. Additionally, policies should be strengthened to speed the deployment of clean and efficient energy technologies, and mandates and standards are vital to drive consumer spending and industry investment into these technologies.
By 2050, non-hydro renewables are expected to account for more than a third of global power generation, with wind and solar growing four to five times faster than every other source of power. This shift to renewable energy sources will help to reduce import dependency, drive inclusive economic growth, create new jobs, and alleviate poverty.

The need to reduce fossil fuel supply and demand
Fossil fuels, such as coal, oil and gas, are the largest contributor to global climate change, accounting for over 75% of global greenhouse gas emissions and nearly 90% of all carbon dioxide emissions. The need to reduce fossil fuel supply and demand is therefore clear and urgent.
Despite 151 national governments pledging to achieve net-zero emissions, global coal, oil and gas production are still increasing, with government plans leading to an increase in global coal production until 2030 and in global oil and gas production until at least 2050. This is despite the fact that demand for these fossil fuels is set to peak this decade, even without additional policies.
To limit warming to 1.5°C, countries should aim for a near-total phase-out of coal production and use by 2040 and a combined reduction in oil and gas production and use by three-quarters by 2050 from 2020 levels. This will require a managed, just, and globally equitable approach, with international cooperation and support.
To achieve this, governments must incentivize massive infrastructure investments in smart transmission and distribution grids, as well as provide support for communities currently dependent on fossil fuels. Policies should also be strengthened to speed the deployment of clean and efficient energy technologies, with mandates and standards to drive consumer spending and industry investment into the most efficient technologies. Fossil fuel subsidy phase-outs, carbon pricing and other market reforms can also help to ensure appropriate price signals.
The transition to clean energy will also require careful policy attention to address employment losses in the fossil fuel industry. This can include retraining workers, locating new clean energy facilities in heavily affected areas, and providing regional aid.
