The International Energy Agency (IEA) says energy-security concerns are accelerating renewable-power plans across a wider group of countries. Its Renewables 2026 forecast, published on 6 Nov 2026, sees almost 4,800 gigawatts (GW) of new renewable power capacity added worldwide from 2026 to 2031—about 57% more than in the previous six-year period. For drivers, the shift matters because it can change how electricity is generated for homes, workplaces and electric vehicles, even though it does not guarantee an immediate fall in petrol or diesel prices.
Key takeaways
- The IEA forecasts almost 4,800 GW of renewable power capacity additions during 2026–2031.
- That forecast is about 57% above the capacity added in the previous six-year period, according to the IEA and Axios.
- Growth is spreading beyond China as countries seek less exposure to imported fuels and volatile energy prices.
- Solar power is expected to lead the buildout, but grids, storage and faster project connections remain critical.
What changed in the new forecast
The IEA’s central message is not that one government has announced a single new global programme. It is that the reason for renewable investment is broadening. Cost reductions and climate policy helped drive earlier growth; after major energy-market disruptions, governments are also treating domestic renewable power as a security measure.
The agency expects the world’s renewable capacity to expand by almost 4,800 GW between 2026 and 2031. Axios independently reported the same forecast on 6 Nov 2026 and described the energy-security effect of the Middle East conflict as a possible lasting influence on market and policy decisions. The comparison is about installed power capacity, not electricity output, oil demand or a 57% reduction in fuel use. It is also a forecast, so actual additions will depend on policy, financing, equipment supply and grid access.
China is expected to remain the largest contributor to global renewable growth, but the IEA sees a broader geographic spread. Emerging and developing economies outside China are forecast to add renewable capacity at a scale that matches advanced economies for the first time in the report’s forecast period. The agency points to stronger activity across India, Southeast Asia, Africa and the Middle East, making the story global rather than limited to the established solar and wind markets.
Why energy security is driving the shift
Imported oil, gas and coal expose countries to shipping disruptions, sanctions, exchange-rate movements and sudden price spikes. Renewable power does not remove every energy risk, but a country with more domestic solar, wind, storage and flexible demand can reduce the amount of fuel it must buy from overseas for electricity generation.
That distinction matters after a supply shock. A new solar or wind project cannot replace a tanker cargo overnight, and power systems still need networks, backup generation and storage. But once connected, renewable assets have no fuel cargo to purchase for each unit of electricity they produce. That gives energy planners a reason to accelerate projects even when climate targets are politically difficult.
Higher fuel prices can also change household and business decisions without making them predictable. The cost of charging an electric car depends on the local electricity tariff, network fees, taxes, time of use and the charging operator; a larger renewable fleet does not automatically lower any one driver’s bill. Readers can compare local pump rates through the live fuel-prices hub and estimate a specific journey with the fuel cost calculator.
What it means for transport
The IEA expects renewable energy use in transport to grow through 2031, with renewable electricity for electric vehicles and biofuels among the main contributors. For passenger-car owners, the most visible change will be the gradual expansion of charging and the electricity systems behind it. The timing will vary sharply by country because vehicle prices, incentives, charger availability and grid reliability are not moving at the same speed.
For commercial fleets, the transition is more operational. Battery-electric trucks and buses need dependable depot or corridor charging, while long-haul operators may continue to combine diesel, gas, biofuels and electrification according to route length, payload and local rules. The forecast therefore does not make a simple petrol-versus-EV prediction. It points to a more mixed transport market in which fuel choice is increasingly connected to power infrastructure.
Drivers considering an electric road trip can check the EV charging-station directory before planning a route. Those comparing conventional and electric running costs should treat any result as location-specific: the IEA forecast describes a multi-year system shift, not a guaranteed saving for a particular vehicle or trip.
The bottleneck is the grid
The IEA says faster renewable construction will only translate into more usable energy if electricity networks keep pace. Projects can be built but remain unable to deliver power when transmission capacity, interconnection approvals or local distribution upgrades are missing. Storage and more flexible demand can help smooth solar and wind output, but they also require investment and workable market rules.
This is why the forecast should not be read as a near-term promise about fuel prices. Crude supply, refinery capacity, shipping costs, taxes and currency movements will continue to influence petrol, diesel and jet fuel. Renewable growth may reduce some countries’ exposure to imported fuels over time, but its effect on pump prices will be indirect and uneven.
What to watch next
- Whether governments convert energy-security plans into auctions, permits, grid contracts and construction.
- How quickly transmission, distribution and storage projects clear connection bottlenecks.
- Whether new fuel-price shocks lead more countries to adjust biofuel blending or EV-support policies.
- How solar-equipment supply chains diversify as renewable deployment spreads across more regions.
Reader takeaway
The important development is a change in the policy motive behind renewable power. Governments are increasingly linking solar, wind, storage and electrified transport to resilience against imported-fuel shocks, not only to emissions targets.
For a driver or fleet operator, the practical response is to follow the local numbers rather than assume a global forecast will immediately change a pump price. Check current fuel rates, calculate the cost of the journey and, where relevant, verify charging availability. FuelPrice’s road-trip planner can help connect those choices to a specific route.
