Backstory: Tidal Power

Earlier this week, offshore wind farms got major financial investment from Google and Good Energies. On Backstory, we look at another way to harness the energy of the ocean: tidal power. Paul Jacobson, Ocean Energy Leader for EPRI, a non-profit electricity research company, and Michael Peterson, professor of mechanical engineering at the University of Maine-Orono and leader of the University’s Tidal Power Initiative, join us to explain how the tides can produce electric power.
