The article discusses a strategic roadmap to transform Sardinia's energy landscape, transitioning from coal power plants to renewable energy sources, with a strong emphasis on hydrogen as a zero-emission fuel. The plan involves surrounding the island with wind turbines and solar grids over almost a decade, ultimately achieving energy independence through green hydrogen, as proposed by the Popular Initiative Law supported by a significant number of Sardinians. The vision is to establish a network of renewable energy infrastructure across various sectors, including public and private buildings, industrial areas, and transportation routes like roads and railways. This ambitious project aims to create energy communities dedicated to generating electricity from green hydrogen, positioning Sardinia as a forward-looking region in sustainable energy practices. By embracing this initiative, the island could stand at the forefront of modernity, joining other advanced nations in the pursuit of zero emissions and energy independence, while combating energy speculation and prioritizing environmental protection.
