The International Energy Agency (IEA) reports the total global investment in energy would hit $3.4 trillion by 2026, with $2.2 trillion devoted to the grid, storage, renewables, nuclear, efficiency and electrification. Electricity grid investments would amount to around $550 billion and battery storage investments would surpass the $100 billion mark. In addition, investment in natural gas would go up to $330 billion. The study indicates that countries and companies alike have become more interested in ensuring energy security and supply due to the disruption in the Strait of Hormuz.

According to the World Energy Investment 2026 report, global energy spending is projected to reach $3.4 trillion in 2026, as there is currently a new crisis resulting from the effective shutdown of the Strait of Hormuz. This crisis is reshaping global capital flows.
The report showcases that the current disruption is an addition to a previous shock in the energy market resulting from Russia’s attack on Ukraine in 2022. This crisis has made both governments and corporations reconsider their approach toward trade routes, with particular emphasis on energy security in Asia and the Middle East.
The International Energy Agency (IEA) states that the impact will accelerate clean energy production, nuclear energy, grid management, energy storage systems and energy efficiency. The crisis is also prompting some countries to maintain or develop fossil fuel networks in a bid to ensure energy security in the short term. The agency adds that nations are increasingly investing in balancing power generation and consumption, enhancing grid stability, promoting electrification and minimizing the vulnerability of fuel networks.
In addition, this report shows that about $2.2 trillion of total energy financing in 2026 will go into grids, battery storage, clean fuels, nuclear, renewables and the electrification and efficiency of energy use.
Funding for electricity generation and infrastructure is estimated at nearly $1.6 trillion, rising to about $2 trillion when the electrification of end-use consumption is included. Financial commitments to electric grids stand at approximately $550 billion and will show almost 20% yearly growth. Meanwhile, capital allocated to BESS is projected to surpass $100 billion.
The biggest destination for power sector allocations is still renewable energy. Global funding for renewable power installations is expected to total $665 billion in 2026, with about $365 billion being spent on solar power. Despite a slowdown in the expansion of renewable financing due to many years of growth, low-carbon commitments make up more than 70% of all power sector spending.
Outlays for nuclear energy are also rising, crossing $80 billion per year, with almost 80 GW of additional nuclear power generation capacity under construction across 15 nations. According to the report, nuclear power plants are becoming an essential part of energy security for many countries.
At the same time, spending on natural gas assets is forecasted to climb to $330 billion in 2026, which will be the highest in the past 10 years. The reason behind this growth is increased capital injection from the construction of LNG ventures in the United States and Qatar.
Meanwhile, upstream oil capital expenditures are expected to fall for a third year in a row, below $500 billion, despite higher crude oil prices. Lower outlays on oil exploration are said to result from high uncertainty about how long this price spike will last, alongside long project lead times.
Coal financing is projected to increase to $180 billion in 2026, its highest level since 2012, with China accounting for nearly 70% of global coal supply spending. According to the report, several Asian economies affected by the present energy crisis may extend the operating life of existing coal-fired generation assets to support electricity security and system reliability during periods of supply disruption.
Energy efficiency is another issue highlighted by the report as being of increasing policy concern in the wake of supply shocks. Capital of $350 billion is deployed on a yearly basis globally into energy efficiency programs, with about 20 nations making plans for even more energy efficiency policies to help mitigate their crisis. According to the agency, policy backing will be necessary to plug any gaps in efficiency.
Based on the report, there has also been a rise in the financial risks associated with future energy developments as a result of geopolitical tensions. The costs associated with finance have increased due to market volatility caused by the conflict in the Middle East.
In relation to capital-intensive ventures such as renewable energy facilities, nuclear developments, and other infrastructure programs, the cost associated with borrowing continues to remain relatively high. This was a key point emphasized by the IEA.
The report further notes how the influence of data centres and artificial intelligence on global trends in energy capital allocation is increasing, especially in the United States. There were orders for gas-fired electricity plants at a record level over the last 25 years, driven directly by higher electricity demands from data centres and artificial intelligence installations.
Additionally, high electricity demand in the United States and the Middle East is limiting the number of turbines available for electricity generation in other countries globally.
According to the executive director of the IEA, Fatih Birol, the world is facing an unprecedented energy security crisis, and it is bound to influence strategic financial decisions in ways similar to what was seen after the 1970s oil crisis. One of the many indications of this can be seen in terms of the growing focus on increasing pipeline capacity, import diversification, improvements in power generation capabilities, energy efficiency initiatives, as well as the increased use of domestic energy sources.
In conclusion, there seems to be a strategy for creating a strategic divide within the global energy picture as the same amount allocated towards transitioning to renewable energy, nuclear power and grids will see a record expenditure towards gas and coal due to the urgent need for securing energy supply. In essence, this means countries are willing to spend heavily on both fronts regardless of their borrowing costs.
