Why don’t we use more tidal power? - The Climate Question podcast, BBC World Service

Tidal power has huge potential as a source of renewable energy, so why don’t we use more of it? Click here to subscribe to our channel 👉🏽 https://bbc.in/3VyyriM In this episode of The Climate Question, the team answer your questions. Drusilla wants to know why so many big tidal energy projects around the world seem to be stalled. Plus, Mark asks if our river estuaries and their ecosystems are vulnerable to climate change? And are “fish discos” a good way to keep fish away from nuclear power stations? Or a colossal waste of money?
