Samira Hussain takes you to Puerto Rico. Back to back hurricanes 5 years ago shattered the island's electricity grid, leading to the longest blackout in American history. Residents are still trying to claw their way out of the darkness. But one Puerto Rican town, in the island's mountainous region, may have found a solution. Arturo Massol Deya is the associate director of Casa Pueblo, he tells us how he's using solar panels to ensure a reliable supply of electricity to his local community.We also hear from Wayne Stensby, CEO of Luma Energy. Last year, the transmission and distribution of electricity in Puerto Rico was privatised and handed to Wayne and his team. He tells us the whole system needs a lot of regeneration and investment.Presenter / Producer: Samira HussainImage: Arturo Massol Deya; Credit; Andrew Herbert BBC
