This is mostly based on the assumption of a 2% growth rate in overall energy consumption, with tidal power as an ever-growing 1% of that. The effect of covering 1% of our current energy usage would be minimal. And, likely, the ability to exploit tidal power will plateau at some (fairly small) amount, due to geographic constraints.
