1. Why
Offshore energy generators are important because they offer a large source of clean and sustainable energy
Energy density sea water is 832 times denser than air so about 6mph of current has more kinetic energy than 220mph
They don’t take up land which can be used for better reasons
Tidal power is also free and creates no harmful byproducts that can damage the environment.

2. Advantages
Tidal stream energy compared to wave and ocean thermal energy is that it is a simple and based off the simple wind turbine
Current turbines are a lot more durable , cheaper to build than wave energy systems, and
advances are
made faster in
this field
