Estimations show that systems built on the west coast of Scotland could produce up to 20 gigawatts and an average of 80 terrawatt-hour per year! Holy cow, that is 1/5 of UK’s total electrical consumption! Hydro and wind take up large portion of installed renewable power sources, including biomass to electricity and biomass heat, Scottish Renewables states in a recent statistic publication.

Major companies invest in wind and solar farms instead of wave and tidal plants. Private investors and large multinational companies don’t like to risk: they stick with something that is working already, no matter what developers of marine renewables demonstrate (like the aforementioned study that would guarantee 1/5 of UK’s consumption from renewable source without the need to sacrifice croplands or meadows!).
