Solar greenhouses in Southern Europe, especially Spain, are crucial for maintaining Europe's food autonomy, supplying quality fruits and vegetables to major consumer countries. Spain, a leading producer with 70,000 hectares of greenhouse vegetable cultivation, uses a sustainable model that drives the economy in provinces like Almería and Granada and contributes significantly to recycling. The sector is exploring the potential of photovoltaic solar energy on greenhouse roofs. Additionally, the Esdeinvernadero.es campaign, co-financed by HortiEspaña and the European Union, aims to promote agri-food products using sustainable technologies in farming and marketing.
