Barcelona looks to skies for energy

Barcelona's solar energy policy mandates solar panels for new buildings, aiming to reduce carbon emissions. Despite the sunny climate, solar energy alone is insufficient due to weather variability, necessitating backup systems. Over eight years, solar panel installations have increased significantly, but implementation issues persist, with some panels not being properly connected. Community initiatives, like a jointly owned solar power station, are emerging. However, energy demand continues to rise, prompting authorities to extend solar energy to public buildings. Experts suggest reducing energy consumption as a long-term solution.
