Nuclear is only scaleable in very large steps, hydro the same, gas also (I presume the burning/generating plants are hard to add capacity to?). However, wavepower is probably incrementally scaleable.

I have not seen this argument before, but it seems to be a reasonable one. Or I may be way off the technology: perhaps offshore wind farms are limited by geology? Perhaps preparing the site infrastructure for future increments is too expensive?

You experts will know...
