The helpless body of a huge whale washed up on the shoreline is always a
sombre sight. But the discovery of a dead 52ft fin whale on Newquay’s
Fistral Beach at dawn last week was particularly depressing for locals,
who have been spotting a growing number of the majestic animals off their
coast in recent months. “It’s heartbreaking,” said resident Kathryn
Fuller.

The increase in whale sightings off Cornwall had been greeted as a sign
that marine life was thriving. But the whale’s death was a reminder that
beachings often have a man-made cause, such as fishing, naval sonar
(which, it is thought, causes whales to surface too quickly, leading to
decompression sickness) or collisions with ships. “These intelligent
beings look so sad and helpless out of the water,” says Danny Groves of
Whale and Dolphin Conservation.

And now there is fierce global debate about whether another factor could
be at play in such incidents: offshore wind farms – a controversy that has
set the passionately pursued ‘green’ agendas of renewable energy activists
and conservationists against one another.

The finger-pointing began in February with a spate of strandings and
deaths of baleen whales (the name for humpbacks, fin whales and blue
whales) on America’s east coast, which some blamed on huge turbines off
the US seaboard.

Research into the deaths found that 40 per cent of them resulted either
from ship strikes or netting entanglement. Some activists suggested that
the whales had become confused because their hearing had been damaged by
drilling during the construction of offshore turbines, making it more
difficult for them to avoid ships.

More recently, in Australia a separate campaign opposing offshore wind
farms in New South Wales claimed they pose a risk to whales there too.
Placards carried by protesters on beaches bore the message ‘Stop these
monsters’, referring not to the leviathans of the deep but to renewable
energy turbines whose rotor blades can span more than 250m – more than 10
times as long as a blue whale.

Such is the divisive nature of the allegations they have even become a
front in America’s bitter politico-culture wars. Speaking at a rally in
South Carolina in September, former US president Donald Trump suggested
that wind turbines off the coast of the US “are causing whales to die in
numbers never seen before”.

Former Greenpeace Canada president Dr Patrick Moore agrees that wind farms
are harmful to whales: “The development of these wind farms is interfering
massively with the actual known habitat of these creatures,” he said in
May. But Moore left Greenpeace in 1986, and has since become a frequent
critic of the green movement. Today, the campaign group disavows his
comments, suggesting that the whale-vs-wind farm controversy may even be a
conspiracy whipped up to discredit renewables.

“Academics have linked these attempts [at controversy] in the US with oil
and gas interests,” says Dr Doug Parr, chief scientist for Greenpeace UK.
Such stories, he adds, “exploit the admirable concern that people have for
the natural environment.” Yet, he acknowledges, “offshore wind needs to be
sited where it will least impact wildlife.”

The most obvious problem is noise. Our seas are getting ever louder – a
2016 estimate of global shipping noise projected a near doubling by 2030.
“Introducing loud underwater noise pollution from military exercises, or
seismic surveys for oil and gas has a dramatic effect on [whales’ and
dolphins’] lives and wellbeing,” explains Groves. “It can cause them
suffering, change their behaviour and drive them away from the places
where they breed and feed. In some cases it can cause them to strand and
die.”

But it’s not just military exercises or seismic surveys that are loud.
Building huge wind farms is noisy work too. According to Whale and Dolphin
Conservation, the use of pile drivers in the construction of offshore wind
farms adversely affects the behaviour of whales, dolphins and porpoises to
distances of up to 25 miles. They can even be injured or killed if they
are too close to the source of the sound, they say.

Rob Deaville, from the Zoological Society of London’s Cetacean Strandings
Investigation Programme, agrees: “If you have porpoises or dolphins living
in an area and you start driving a pile into the seabed to erect a wind
turbine, that generates a lot of noise and that definitively has been
demonstrated to have a dissuasive effect. It drives animals away from an
area.”

Deaville, who investigates dead animals on the UK coast and studies the
threats they face, is used to the hubbub that accompanies a high-profile
stranding: “We’ve never been able to definitively link any of the
strandings we’ve investigated with wind farm activity,” he says. “That
said, there’s a huge body of evidence that does demonstrate the impact of
wind farms on some species of cetacean.”

An analysis published by the National Academies of Sciences, Engineering
and Medicine in the US last month called for greater investigation into
how offshore wind farms affect water flows and food sources for critically
endangered whales near the Massachusetts coast.

For Deaville, such work is essential as part of a wider assessment of wind
farms’ pros and cons. “It’s useful to have that debate as a society,” he
says. “Nothing is cost-free.”

The question, then, is what happens after a wind farm is built and becomes
operational, and quieter? It’s a mixed picture.

“In some wind farms animals don’t come back in numbers like before,” says
Deaville. “In some areas, though, they might come back in greater numbers
than before.”

The theory is that when fishing in and around wind farms is banned due to
a risk of entanglement on the piles, that then acts as a reef, which lures
marine species back into the areas. “You get more fish, and therefore more
cetaceans to feed on the fish,” says Deaville. “So there’s no easy
answer.”

At Newquay – which has no offshore wind farm nearby – there is no obvious
cause behind the fin whale’s death. “We will not know what happened to
this individual until a necropsy is performed. And even then, the real
cause may never be known,” says Groves.

Whale and Dolphin Conservation now supports the development of marine
renewable energy developments – in appropriate locations. However, it
believes that, until impacts can be fully mitigated, new renewable energy
programmes should be excluded from important Marine Protected Areas, or
MPAs. “Buffer zones should be created around MPAs, so as to avoid
displacing whales, dolphins and porpoises from important feeding and
breeding areas.” says Groves.

The case against wind farms may be less than clear cut, but, says Groves,
“What is certain is that these ocean giants help keep the seas healthy. A
healthy ocean helps us fight climate breakdown.

“They are our allies in this struggle and offer hope, so we need to
prioritise increasing their numbers, not place them in harm’s way.”
