Wave
energy causes surfers rift
Plans for wave
energy machines off the north Cornwall coast have created
a split in the surfing community. Some surfers are concerned
that the machines will take energy from the waves and reduce
wave heights. They also fear it would put at risk the surfing
industry, which is worth an estimated £64m a year to
the region.
But environmental campaigners
Surfers Against Sewage said wave height will only be reduced
by a small amount and it is worth the environmental benefits.
The
row has erupted over plans for a £20m Wave Hub - a seafloor
"socket" which will connect wave energy machines
to the mainland. The proposed power station, to become operational
in 2008, will involve up to 20 sets of machines, with pumps,
pistons and turbines, about 10 miles (16km) out to sea off
St Ives Bay, generating electricity for 14,000 homes. The
machines will be placed across a three-mile (5km) stretch,
but because of the angle of the swell, could affect the 20-mile
(32km) coastline from St Ives to Newquay.
John Baxendale, a chartered
physicist and engineer who runs a surf forecasting agency,
said it could ruin the coastline's renowned surfing. He told
BBC News: "It is fairly obvious to me that any barrage
of energy extraction would create a wave shadow because it
would remove the energy from the surf. "It will not just
affect the height, it will also affect the quality of the
surf. "Surfers voting for this are like turkeys voting
for Christmas."
It should not make a
noticeable impact most of the time Andrew Knights, Surfers
Against Sewage
He said he was for renewable energy in the right place. "Put
them off a rocky coast like the west of Scotland, somewhere
it does not affect the economy," he said. Andrew Knights,
of Surfers Against Sewage, said the effect would be an 11%
reduction in surf height at most according to an environmental
impact assessment by consultants Halcrow. "It should
not make a noticeable impact most of the time," he said.
"We are satisfied that it is a good thing and we are
backing it. "You have to consider the long-term environmental
gains and they outweigh any small impact on wave heights."
If the plans get government
consent, construction could start early next year. Nick Harrington,
project manager for the South West Regional Development Agency,
said: "We identified right from the outset that the impact
on surfing beaches would be one of the key factors for us.
"We asked Halcrow to determine what that impact might
be and if the conclusion had been that it would have a serious
impact on Cornwall, that would have posed the question about
whether we should continue with the project. "But the
conclusions they have reached suggest that the impact is very
minor and that's why we feel confident putting in our application."
