There's a lot if you look for it, recent developments in tidal are incredibly positive and we're absolutely going to see a rapid uptake in marine electrification as existing technology progresses through the market. Most people never really think about the resources used and pollution caused by small boats but one of the big destructive forces at play is the infrastructure requirements - small boats need big boats to supply their fuel stations.

Transitioning away from this system and instead using costal tidal generators to charge electric ferries and barges could be a total game changer in many areas, especially many of the highly trafficked and polluted tidal basins like in north Brazil, Nigeria, or island clusters like in the Philippines. Also the intercoastal waterways around the US and other leisure spots.

We're making great progress in many areas and I really think it's important to acknowledge this and cheer it on least we get so caught in a false sense of doom that we just give up.
