Tidal energy could be huge – why isn't it?

It's estimated that we could (practically) capture enough tidal energy to power all homes in the United States TWICE over – but we can only manage a tiny fraction of that right now. For a planet that is 70% water, why is this technology still so far behind other renewables? Are things about to change? We're destroying our environment at an alarming rate. But it doesn't need to be this way. Our new channel Planet A explores the shift towards an eco-friendly world — and challenges our ideas about what dealing with climate change means. We look at the big and the small: What we can do and how the system needs to change. Every Friday we'll take a truly global look at how to get us out of this mess. #PlanetA #TidalPower #TidalEnergy Reporter: Aditi Rajagopal Camera and video editor: Henning Goll Supervising editor: Kiyo Dörrer, Malte Rohwer-Kahlmann, Joanna Gottschalk Special thanks for the background interviews: Lisa MacKenzie and Matthew Finn, The European Marine Energy Centre Andrea Copping, Pacific Northwest National Laboratory Thomas Adcock, Oxford University Read More: IEF on Tidal Power: https://www.ief.org/news/tidal-power-...
