## Key points

- Ageing grids are holding back wind and solar power.
- The IEA says grid investment must rise 50% by 2030.
- China curtailed 360 terawatt-hours of renewables in early 2026.

## Summary

Outdated electricity grids are becoming a major obstacle to the shift from fossil fuels to renewable energy, because many cannot carry or distribute all the power produced by new wind and solar farms. At U.N. climate talks in Antalya, Turkey and Australia are pressing for stronger action on fossil fuels, renewables and grid upgrades, which also matter for countries seeking greater energy security.

The International Energy Agency says annual investment in electricity generation has risen by almost 70% since 2015 to $1 trillion, while grid spending has grown at less than half that rate. It estimates yearly grid investment must rise by about 50% from the current $400 billion to meet demand through 2030. Grid limits have already led China to curtail 360 terawatt-hours of wind and solar power in the first half of 2026, while India curtailed 11 terawatt-hours of solar over 15 months spanning 2025 and 2026.
