That's my point (I think). The research has been disproportionately biased towards wind power (and solar power outside Europe), so yes, it's more efficient than the alternatives.
Tidal power is environmentally contentious, whereas wave power has relatively few drawbacks in environmental terms. Granted, wave power is logistically very tricky (they ran into serious difficulties during the eighties with generators breaking up in rough weather), but we haven't done enough research to right it off. There's now't in it for our European pals, so if the UK doesn't invest in wave power research, it will continue to lag behind wind power.
