Q.Does taking energy from the tides have an effect on the moon?
A.Yes. The gravitational forces of the Earth's tidal bulges on the Moon drag it into a faster, higher orbit, causing it move 3.82cm further away per year.
Q.What are the fors and againsts of tidal generation?
A.Pros: free, renewable, and clean source of energy, no solid pollution, tides active 24h. Cons: displacement of wildlife, not cost effective.
Q.Why are the effects of tides not felt further up a river?
A.Tides only have an effect to a certain point up a river because the waves lose energy as they go upstream, & the force of the river itself becomes more.
