solution
As tidal electricity can be create by the several technology but some mains are tidal barrage and tidal fence and tidal turbine etc
tidal power is the oldest form of energy generation
as we know coastline area often experience 2 high tide and 2 low tide on the daily basis
but difference of water level at least 5 meter high to produce the electricity
so we only install it along the coastlines and Ocean generate more energy than air because ocean water is 832 time more dense than the air
so correct answer is 5 meter
