This document discusses developing a plan to make Hastings, UK more sustainable. It first examines Hastings' current energy demand and local generation, which is primarily from fossil fuels and meets only 0.02% of total demand. Second, it outlines Hastings' renewable energy potential from solar, wind and hydro sources, totaling 1.5 TWh annually. Finally, it proposes creating an interactive planning tool to design an action plan, informed by research into baseline demand forecasts and efficiency opportunities. Next steps would analyze impacts and explore additional renewable technologies. An event may also be held to engage the community.
