Another good question -- sorry to say I don't have a great answer to this one. In general, I'd say wave power is one of several technologies that in theory could go a long way toward meeting human energy needs, but which is extremely nascent/untested at a large scale, and therefore pretty difficult to bet a climate-safe future on. Will definitely be interested to see if and how wave energy develops, and if so what the environmental impacts might look like.

Also, you're welcome!
