This isn't exactly for a detailed discussion. I want some leads for an another timeline I am making. I need some list of possible PODs for the British or French Empire to run on decentralised and Sustainable energy that would have effects on their settled and resultant countries later in a highly positive way. So can anyone think of a possible POD? No Oil/Coal allowed in any stage after the first round of mass manufacturing. The source and the process should be sustainable,versatile and highly efficient. Any invention anywhere by anyone and anyhow?
