According to the IEA's World Energy Investment 2026 report, The current turmoil represents the second major global energy crisis in five years, following the triggered energy shock. Russia's invasion of Ukraine in 2022. IEA Executive Director Fatih Birol called the situation the worst energy security crisis in decades, saying it could impact global energy policy in the same way as the oil shocks of the 1970s. 2026.

Renewable energy continues to attract the largest share of energy sector investment. The report projects that investment in renewable energy will total $665 billion, $365 billion will be allocated to solar power projects, and more than 70 percent of global investment in power generation will be allocated to low-emission technologies. $80 billion per year, driven by growing interest in energy security and stable baseload generation. About 80 GW of new nuclear capacity is currently under construction in 15 countries.
Battery energy storage is also becoming a major investment category, with spending projected to exceed $100 billion in 2026. Meanwhile, investment in the electricity grid is expected to reach $550 billion, reflecting the growing need to integrate renewable energy sources and support electrification.
LNG investment is rising and oil costs are rising. declining
Despite high oil prices, the IEA expects investment in the oil sector to decline for the third year in a row, falling below $500 billion. The agency cited uncertainty about future oil demand, long project development cycles, supply chain constraints and tightening markets for offshore drilling.
In contrast, investment in natural gas is projected to reach $330 billion, the highest
