In which we learn that to get by on wave power you need to be very very insular -- that is, have a small number of people per unit length of exposed coastline (sounds like a nice place to me, but the British Isles don't fit the description) -- and also that our food habits, especially for red-blooded carnivores with meat-eating pets -- amount to more than half our driving habit in energy. There is a real energy case to be made for vegetarianism (approximately twice as efficient) and even more for veganism (another doubling).
