This document discusses sustainable energy in schools and communities. It focuses on community bridging organizations, environmental champions, and funding sources that can support sustainable energy projects at the national, regional, and local levels. Specific examples mentioned include Ireland's only community-owned wind farm that was established in 1999 and now provides power to 2,500 homes. The document also notes that measuring energy consumption in Irish communities, partnering with communities to promote greening, and doing deep interventions with some communities has helped save over 5,000 tons of carbon dioxide in Ballina and create more sustainable communities.
