The Portuguese island of Porto Santo is serving as a real-world testbed for a fossil-fuel-free future. Through a collaborative smart island initiative, the territory is integrating wind and solar power with electric vehicles and stationary battery storage. By utilizing smart charging and second-life electric vehicle batteries to stabilize the local grid, the project demonstrates how isolated communities can overcome the intermittency of renewable energy and reduce their reliance on imported fossil fuels. This sustainable energy model offers a scalable blueprint for transition strategies on other islands globally.
Porto Santo, located in the Madeira archipelago, is piloting a “Smart Fossil-Free Island” project to transition away from its historic reliance on diesel-powered generators.
The initiative integrates renewable energy sources, specifically wind and solar, into the island’s localized electricity grid.
Electric vehicles (EVs) on the island act as mobile energy assets, utilizing smart charging to pull power from the grid when renewable generation is at its peak.
Vehicle-to-grid (V2G) technology enables these electric vehicles to feed stored energy back into the local grid during periods of high demand.
Decommissioned electric vehicle batteries are repurposed as stationary energy storage, providing a second life for the batteries while helping to balance grid fluctuations.
The project is a collaborative effort involving local utility Empresa de Electricidade da Madeira (EEM), regional authorities, and the Renault Group.
The Porto Santo model serves as a test case for how larger, isolated regions can manage the variability of high-penetration renewable energy systems.

after that little scottish island became 100% renewable / battery powered … great to see a bigger island do the same.
Once in place nothing more needs to be purchased to power the island. Simply harvest and store energy everyday because of the sun (even the wind is a result of the sun!)

That is really stupid propaganda – they are literally handful of people having no energy consumption economy and yet the aim is 70%.
Interesting look at energy systems. What factors should be considered when connecting smaller power networks to larger infrastructure??
Theres also the desalination plant, they produce enough even for the golf course.
