What Powers The World? An Overview Of Global Energy Consumption

In 2023, the world’s energy consumption was like a buffet of different sources, each contributing its own flavor to the global energy mix. Fossil fuels remained the main course, but renewables and nuclear energy provided some interesting side dishes.
From the oil to the ever-present coal, and the growing presence of renewables, the energy sources differed a lot. Each type of energy plays a role in meeting global energy demands. Here’s a look at how different energy sources power the world. Let’s dive into the details and understand their place in the global energy puzzle.
Oil: The Dominant Energy Source

In 2023, oil was the most consumed energy source, contributing 196 exajoules and accounting for 32% of the world’s energy consumption. Oil is extracted from the ground and refined into various products like gasoline, diesel, and jet fuel, powering transportation and industries worldwide. Its high energy density and ease of transport have made it a cornerstone of the global economy. Despite its drawbacks, it remains an important part of the energy mix.
Coal: A Key Player

Coal was the second-largest energy source, contributing 164 exajoules and making up 26% of global energy use in 2023. Coal is mined from the earth and burned to produce electricity, heat, and industrial energy. It is abundant and relatively inexpensive, making it a staple in many countries’ energy strategies. However, coal combustion is a source of air pollution and carbon dioxide emissions. Efforts to reduce coal use are ongoing, but it continues to be a vital energy source, especially in developing economies.
Natural Gas: The Cleaner Fossil Fuel

Natural gas accounted for 144 exajoules or 23% of the world’s energy consumption in 2023. Extracted from underground reservoirs, natural gas is primarily composed of methane and used for electricity generation, heating, and as an industrial fuel. It burns cleaner than oil and coal, producing fewer pollutants and greenhouse gases. Its flexibility and efficiency have made it a popular choice for power plants and residential heating. However, methane leaks during extraction and transportation can negate some of its environmental benefits.
Hydro-Electric: Harnessing Water Power

Hydro-electric power contributed 40 exajoules, making up 6% of global energy consumption in 2023. This renewable energy source generates electricity by using the flow of water to turn turbines in dams. It is a reliable and low-emission energy source, widely used in countries with abundant water resources. Hydropower plants provide steady, large-scale electricity and help with flood control and irrigation. Hydro-electric power remains a cornerstone of renewable energy strategies worldwide.
Nuclear Energy: The Steady Giant

In 2023, nuclear energy provided 25 exajoules, accounting for 4% of the world’s energy consumption. Nuclear power plants generate electricity through controlled nuclear fission reactions, offering a high energy output with low carbon emissions. This makes it an attractive option for reducing greenhouse gas emissions. Despite its challenges, nuclear energy remains a big player in the global energy mix, providing a reliable and stable energy supply.
Other Renewables

Other renewable energy sources, including wind, solar, and biomass, collectively accounted for 51 exajoules or 8% of global energy consumption in 2023. These energy sources are rapidly growing due to advancements in technology and decreasing costs. Wind and solar power harness natural forces to generate electricity, while biomass converts organic materials into energy. Renewable energy sources are praised for their low environmental impact and sustainability. However, their intermittent nature and reliance on weather conditions pose challenges for consistent energy supply.
Renewables’ Increasing

In 2022, renewables, such as wind, solar, and geothermal, represented 14.4% of total electricity generation. Renewables saw an extraordinary annual growth rate of 15%. It was driven by big gains in solar and wind. Non-renewables, by contrast, only managed a tiny 0.4% growth rate.
Hydro-Electric In 2022

With hydroelectric power moved into the renewable column, they accounted for over 29.3% of all electricity generated in 2022. Renewables saw a 15% growth rate in 2022, reflecting a big shift towards more sustainable energy sources. This trend indicates a growing global commitment to reducing carbon emissions and prioritizing renewable energy.
The Future

As technologies improve and costs decrease, the role of renewables in the energy mix is expected to continue its upward trajectory. Proponents of renewables promise a cleaner and more sustainable future. Only time will tell if that vision will come to life.
Energy Storage: The Key To Consistency

As renewable energy sources like wind and solar grow, energy storage becomes more and more important. Technologies such as batteries and pumped hydro storage help to store excess energy generated during peak production times and release it when demand is high or generation is low. Innovations in energy storage are important for addressing the intermittent nature of renewables, ensuring a consistent and reliable energy supply.
Grid Modernization

Modernizing the electric grid is important for integrating a mix of energy sources, including renewables. Smart grids, which use digital technology to manage electricity more efficiently, are a key part of this transformation. These grids can better respond to changes in energy supply and demand, reducing waste and improving reliability.
Summary

In 2023, the global energy landscape was a mix of traditional and emerging sources. Fossil fuels like oil, coal, and natural gas dominated consumption, but renewables and nuclear power made big contributions. Hydro-electric power continued to be a cornerstone of renewable energy.
