Tidal Energy In the UK

Fascinating.  They have tidal energy generators in the UK as reported by this article by Chris Goodall in The Guardian.  I find it amusing that they call the energy “renewable” when it's really depleating the angular momentum of the earth's rotation and the moon's orbit.

Still, as far as I can tell, renewable always means a big enough supply that we can't imagine when we'll run out. That's the way new energy supplies often start out.
