Chapter 20 Tidal Power

摘要: Publisher Summary The potential energy of the tides has been variously estimated in past. Recent estimates tidal dissipation on Earth include Munk and Macdonald who put it at about 3·10 12 W. They suggested that up to one-third this power was being spent shallow seas. This implies maximum available for development all earth's seas may be 10 6 MW. United Kingdom current uses 220 TWh electrical per annum, so can realized only make a strictly limited contribution supply. In certain areas could considerable importance because developed large amounts, does not use exhaustible resources, produces neither waste, nor pollution causes minimal disturbance environment. geographical distribution sites north-west European shelf area where is potentially capable presented chapter.
