You might want to reconsider having a turbine as your neighbour with new research revealing the level of noise wind farms make at night.
Electricity isn’t the only thing wind turbines are generating with concerns that the renewable energy source could trigger noise complaints.
Researchers from Flinders University are looking for ways to decrease wind turbine noise by improving their manufacturing guidelines and design.
The ‘swoosh’ sound – technically known as amplitude modulation (AM) – from turbines is likely to be heard by neighbouring residents up to five times more in the night than during the day.
Wind direction, season and wind farm distance are all contributing factors to the level of noise generated.
PhD candidate Duc Phuc Nguyen and acoustic expert Dr Kristy Hansen used a combination of long-term monitoring and machine learning to determine the characteristics that contribute to the noise pollution.
“The noise seems to worsen after sunset when amplitude modulation can be detected for up to 60% of the night-time at distances around 1 km from a wind farm,” Nguyen says.
“At greater than 3 km, amplitude modulation also occurs for up to 30% of the night-time.”
Wind Farm Noise Study
The Wind Farm Noise Study which is based at the Adelaide Institute for Sleep health at Flinders University is investigating the repercussions of wind farm noise on sleep disturbances.
According to Dr Hansen, the directional nature of wind turbine noise affects residents in downwind and crosswind conditions.
“Using these recent advances in machine learning, we have been able to develop an AM detection method that has a predictive power close to the practical limit set by a human listener”.
“These studies advance our ability to measure and monitor the noise from wind turbines that is likely to be more annoying than other noise types at the same level.”
So if you’re one who likes their sleep, you might want to consider setting up camp next to some quieter neighbours.
Britain is facing a surge in cold weather, with icy conditions and fog expected for much of this week
The UK Met Office has issued a Yellow warning, which means there could be damage to buildings as Britons brace for cold conditions.
Like much of Europe, the UK are bracing for very strong winds on Wednesday, causing disruption to travel and some utilities.
Drivers are also urged to take extra care on the roads, with warnings in place for icy stretches forming on UK roads.
But some residents who are seeking to heat their homes are on edge, as power prices remain high.
Peter Smith is the director of policy and advocacy at National Energy Action, who said the rising cost of living is impacting Britons.
“The average annual bill has almost doubled since this time last year.”
The organisation seeks to close the gaps when it comes to energy affordability. It predicts 6.7 million UK households will be in fuel poverty in the coming months.
This means millions of Britons will be unable to afford living in a warm, dry and safe home.
“So far the milder than usual weather has protected many from the spiralling bills as they haven’t needed to heat their homes as high or as long as usual,” Mr Smith said.
How to keep warm without blowing your bill
UK Prime Minister Rishi Sunak has urged people to make their own decisions, as he met with world leaders in tropical Bali last week.
“There are things that we can do—all of us—to improve the efficiency with which we use energy, to be careful about it,” he said.
For example, an efficient heater; taking advantage of the sun, where appropriate; and rearranging furniture are some cost-effective methods to reduce the burden on gas and energy bills.
In addition, there are some other cheap ways to reduce dependence on gas and electricity bills, as the temperature continue to plunge.
close off rooms you’re not using
lower the temperature of heating
make sure windows are fully closed
block cold drafts from under doors using door snakes or carpet.
The UK Government has placed a cap freeze on energy prices.
This means households will pay an average £2,500 on their energy bills. But there is a catch: if households use more, they pay more.
National Energy Action believes an additional 2.2 million homes could be in fuel poverty, when compared to the same time last year.
Why are energy prices so high?
As demand increases, so too does the cost of heating homes.
But there is another factor, which has sent prices rising across Europe: the war in Ukraine.
Poland President Andrezj Duda spoke to a hoaxer posing as France counterpart Emmanuel Macron, on the night a missile hit near the Poland-Ukraine border.
The news was confirmed after two Russian pranksters, Vovan and Lexus, posted a recording of the incident, and Duda’s office also affirmed the incident.
During the call, Duda was asking who was responsible for the attack on November 15, wanting to avoid a war with Russia.
The missile landed six kilometres from the border.
Initial reports suggested the missile was Russian-made, but it was later discovered to likely be a Ukrainian air defence missile.
This is the second time the pranksters have targeted the Poland President, who have made their names going after celebrities and politicians, especially those opposed to the Kremlin.
Russian missile hits Poland, as the west assesses the attack on a NATO member
Reports a Russian missile has landed in Poland, killing two people. A projectile struck an area where grain was drying in the village of Przewodów, near the Ukraine border.
An anonymous U.S. intelligence official suggested a barrage of Russian missiles hit the Ukrainian power grid, and spilt into neighbouring Poland.
Poland is a NATO member, therefore, this signifies a potential escalation to the ongoing war. It also marks the first time weapons have impacted a NATO country.
Emergency talks
Currently, the Polish government are holding urgent talks. A Polish spokesman Piotr Mueller has confirmed that top leaders are holding an emergency meeting regarding the “crisis situation.”
Under Article 5 of NATO, an attack on one country is considered an attack on all.
The White House has not confirmed the reports but the Pentagon is assessing the situation.
While NATO has taken collective defence measures on several occasions, including in response to the situation in Syria and the Russian invasion of Ukraine—it has only invoked Article 5 once.
For the first time in its history after the 9/11 terrorist attacks against the United States, NATO evoked Article 5 and came to the defence of the United States.
