Environmental Impact
• They have little potential for chemical pollution.
• They will have little visual impact except where shoremounted.
• Noise generation is likely to be low – generally lower
than the noise of crashing waves. (There might be lowfrequency noise effects on cetaceans, but this has to
be confirmed.)
• They should present a small (through not insignificant)
hazard to shipping.
• They should present no difficulties to migrating fish.
• Floating schemes, since they are incapable of extracting
more than a small fraction of the energy of storms, will
not significantly influence the coastal environment. Of
course, a scheme such as a new breakwater
incorporating a wave energy device will provide coastal
protection, and may result in changes to the coastline.
Concrete structures will need to be removed at the end
of their operating life.
• Near-shore wave energy schemes will release an
estimated 11 g of CO2, 0.03 g of SO2 and 0.05g of NOx
for each kWh of electricity generated (Thorpe,1999),
making them very attractive in comparison to the (see
the companion volume, Boyle et al., 2003). Thus wave
energy can make a significant contribution in meeting
climate change and acid rain targets.
