While Iberdrola is very much a global energy company these days, much of the Spanish firm's most cutting-edge work still takes place on the Iberian Peninsula.

One of Iberdrola's latest initiatives sees the company providing households and businesses in Portugal with access to renewable energy, not through generation alone, but by building a series of what it calls "solar communities".

These small networks of photovoltaic panels, located in villages or towns, allow participants to share clean electricity without actually owning a single panel themselves.

The company currently has eight solar communities under development across Portugal, as well as two that already fully operational, bringing the total to ten projects spread across the country.

Together, they are projected to share around 1.7 million kilowatt hours of renewable energy and avoid more than 250,000 kg of CO₂ emissions.
