Fish could get injured by tidal power, their behaviour plus
that of seals etc and diving birds needs to be observed to assess how safe
underwater turbines would be.
From observations through spot checks and day long observations
built up over a long period of time it can be shown that the prototype
underwater turbines on the seabed would be safe from interactions with marine
life.
·
People don’t disclose when things go wrong
installing the wave turbines because they don’t want to disclose commercial
secrets.
·
Little noise pollution from acoustic sensitivity
analysis of turbines noise pollution
·
Up to 29 TW capacity for tidal power in Atlantic
basin
·
Up to 7 TW of potential tidal power in Pacific
basin
Tidal power is more reliable than wind, is a secure source
of electricity
·
With no nuclear waste
Tidal turbines do not affect sonar arrays as wind turbines
would affect effectiveness of radar detection.
Barnacles and algae could be a problem (lifetime of turbines
tbd as they are prototypes still but a very long lived turbine would greatly
enhance the economic benefit of the project)
