What are the biggest sources of energy today?
…of total energy supply. Low-emissions sources – renewables and nuclear – accounted for around 20%.
Global energy demand rose by 1.3% in 2025 (a smaller rise than in 2024 but in line with the previous decade’s average). To meet this increase, all major fuels and technologies expanded.
The trends indicate that changes to the global energy mix are gathering pace. One energy source grew much faster than the others: solar PV. It met 27% of the world’s energy demand growth in 2025 – the first time a modern renewable source covered the largest portion of growth. Natural gas covered…

How the crisis is reshaping energy investment
…through the Strait of Hormuz have been felt most acutely.
The report projects that global energy investment will reach $3.4 trillion in 2026, a slight increase year-on-year. Around $2.2 trillion is expected to go towards grids, storage, low-emissions fuels, nuclear, renewables, efficiency and electrification in 2026, while around $1.2 trillion is set to be invested in oil, natural gas and coal.
Despite higher oil prices, oil investment is expected to decline for a third consecutive year in 2026. The report finds that uncertainty over the duration of the price spike, long project lead times…

7 certainties about energy for this age of uncertainty
…this-age-of-uncertainty. He identifies seven clear trends that can serve as guideposts:
The world has entered the Age of Electricity. Oil and gas will still be widely used for many years to come, but the use of electricity is growing twice as a fast as overall energy demand.
Renewables will keep growing. Despite significant headwinds, renewables are meeting a large amount of the rising demand for electricity in many countries around the world, often because they are the most competitive option.
Nuclear power is making a comeback. After a series of setbacks in the 2010s, nuclear is on…

How the global landscape for energy investment is changing
…available domestically – including renewables, nuclear power, efficiency improvements and, in some cases, coal. Investment in renewable power generation projects is expected to total around $665 billion in 2026, with well over half of it going towards solar projects alone. Nuclear investment in 2026 is expected to be 75% higher than a decade ago, while coal investment is set to reach its highest level since 2012.
To better understand how investment choices impact energy security, our analysis looked back over the past decade. It found that cumulative investments in efficiency, electrification, biofuels and electricity generation from renewables and nuclear together avoided…

The energy crisis and electrification
…processes – is expanding rapidly, with investment growing around 15% year-on-year, according to our recent World Energy Investment report https://www.iea.org/reports/world-energy-investment-2026. Electrification is also one of the key trends contributing to the strong growth in global demand for electricity, which increased more than twice as fast as overall energy demand https://www.iea.org/reports/global-energy-review-2026/key-findings last year.
Investments in renewables, nuclear, electrification and energy efficiency in the past decade have improved energy security in major fuel-importing regions, our investment report finds. At the same time…
