You may have never heard of TED (no, not The Energy Detective),  but they have some amazing speakers.  You can really get lost for a day just perusing their website and watching the presentations.

Two of my "sustainability all-stars" have spoken at some of their events and I highly recommend watching their talks.

William McDonough is an archcitect focusing on sustainable design and was a co-author of one of the biggest books of the sustainability movement, Cradle to Cradle.

Amory Lovins is chief scientist of Rocky Mountain Institute and has written many books, including: Natural Capitalism, Winning the Oil Endgame, and Small is Profitable.

They were both involved in The Natural Advantage of Nations.
