Where does Spain's electricity come from?
Electricity does not come from a single source. It comes from a combination of technologies that changes over time.
In 2024, 56.82% of electricity generated in Spain was renewable.
The leading technology was Eólica, accounting for 23.21% of the total.
The current electricity mix
Spain's electricity system combines renewables, nuclear and gas. Coal, which still had weight a decade ago, is now residual.

How the mix has changed
The current snapshot is best understood with the long series: more renewables, more solar, less coal, a stable nuclear role, and gas combined-cycle plants as flexible technology.

Renewables vs non-renewables
Most electricity generated in 2024 was already renewable, though the system still relies on nuclear and combined-cycle plants.

What the data tells us
1 Spain generates a large share of its electricity from renewable sources.
2 Wind power is one of the leading sources in the system.
3 Gas combined-cycle plants remain key for flexibility when renewable output is lower.
