  • 13. EcoBro community energy projectInspiration Saul Griffiths - Wattzon Poptech 2008Saul Griffiths, and David MacKay on sustainable energy plans that add upThe questionCan we make community scale sustainable energy plans?What we did1.) Understand energy use of a group of people interested in sustainabilityIn the Snowdonia North Wales area.Next: 2.) Use this as the foundation for building a sustainable energy plan...
