Within the Arctic, the place the dependable provide of vitality can imply the distinction between life and demise, one group is main the best way in one of many planet’s most unusual renewable vitality transitions.
For greater than 100 years, the economic system of Svalbard, Norway — a gaggle of islands close to the North Pole — has revolved round coal mining. However burning coal warms the planet, which contributes to the local weather change that’s now melting Svalbard’s glaciers.
The Norwegian authorities has now mandated Svalbard shut its final coal mine inside two years.
“We’re pleased with the mining trade,” stated Heidi Theresa Ose, CEO of the coal mining firm, Retailer Norske. “On the identical time, we’re now trying into the longer term and discovering new methods to contribute with vitality.”
CBS Information traveled to the world’s northernmost and fastest-warming group of Svalbard. What scientists are studying there helps People perceive the modifications occurring in the US. Because the Arctic warms, it provides to rising sea ranges alongside our coasts and instability within the environment that contributes to our excessive climate occasions.
Whereas Svalbard intends to transition to renewable vitality, there’s little or no information on how effectively wind and photo voltaic can carry out within the islands’ harsh winter situations, the place there is not any solar for months at a time.
Renewables within the Arctic
In a spot as chilly and distant as Svalbard, any disruption to the off-grid energy provide might require a complete evacuation of its 2,500 residents to mainland Norway, which is 600 miles away by boat or airplane.
With that in thoughts, Retailer Norske has partnered with scientists on the College Centre in Svalbard to start reliability testing of the world’s northernmost photo voltaic park, on the location of Isfjord Radio, a distant luxurious resort. The resort runs on mills powered by diesel gas.
“We do not have a variety of expertise of how (the expertise) can deal with the tough local weather and climate situations that now we have up right here,” Ose stated. “We have now a job to confirm the expertise within the Arctic local weather.”
Retailer Norske stories robust outcomes from its 360 photo voltaic panels. In summer season, when the solar shines for twenty-four hours, the panels provide all the facility wanted to function the resort.
In spring, the corporate realized the panels can gather each direct daylight and light-weight that bounces off the snow. Ose stated whereas gas remains to be wanted within the complete darkness of winter, the resort has been capable of lower diesel consumption by 70%.
The subsequent testing floor would be the city of Longyearbyen, inhabitants 2,500, which is taken into account the northernmost group on the earth. In October, it stopped burning coal at its energy plant and transitioned to cleaner, however nonetheless soiled, diesel gas. The city intends so as to add renewables to Longyearbyen’s vitality combine as these applied sciences are confirmed dependable within the Arctic.
Along with Longyearbyen, there are about 1,500 communities above the Arctic Circle, the place individuals dwell off-grid. Retailer Norske plans to promote its renewable vitality options to these communities, which embody settlements throughout Canada and Alaska.
“In the event you put all these 1,500 (communities) collectively, then you might have one thing actually massive altogether that might have an effect,” stated Anna Sjöblom, a meteorologist on the College Centre in Svalbard, who’s collaborating on the venture.
Avalanche safety expertise
Past renewable vitality, Longyearbyen can also be the place Retailer Norske and the College Centre in Svalbard have developed new expertise to assist predict one other risk to the group’s well-being — avalanches.
Whereas winters are very chilly, snowfall is mostly gentle. However in January of 2015, a significant storm hammered the island with blinding wind and snow. Greater than 16 ft fell in about 12 hours in some spots.
These uncommon situations triggered an avalanche on one of many city’s mountains — the primary to ever do critical harm to Longyearbyen. The snow ripped properties off their foundations and left them in a pile. Two individuals died, together with a younger lady.
“I knew the lady,” Line Nagell Ylvisåker, Editor of the Svalbard Put up newspaper, remembered. “She went to kindergarten with my daughter. So, it was actually shut and laborious to know that it occurred.”
Since that deadly avalanche, Martin Indreiten with the Artic Security Heart on the College Centre in Svalbard, has led the hassle to defend the group towards the specter of future avalanches.
Indreiten stated the chance of an avalanche has all the time been reliably highest within the spring, however as Svalbard warms, now they will occur at different occasions of the 12 months, as effectively.
“It is the uncertainty,” Indreiten stated. “You do not know,”
Norway spent $25 million to construct a dam on the backside of the mountain to cease tumbling snow and defend the city. Larger up on the mountain, it constructed avalanche fences that assist preserve the snow from sliding down.
Indreiten designed an early-warning system that might give individuals time to evacuate. Working with the Norwegian cell firm Telenor, Indreiten and his colleagues developed the low-cost snow senor.
The gadgets are put in in distant areas. They bounce a beam off the snow to measure its depth and sends again lots of of measurements every day. Every gadget can last as long as 10 years on a single battery and prices simply $600.
“We’re getting data from the locations we wish to get data, and the associated fee is so low that many can use it,” stated Indreiten.
Avalanches are an issue in communities around the globe. Within the U.S. every winter, 25 to 30 individuals die in avalanches, principally in nationwide forests, based on the Nationwide Avalanche Heart.
Indreiten hopes the brand new expertise may be helpful worldwide. It has already been put in in one other avalanche-prone group on mainland Norway.
“When you’ve got higher instruments to do forecasting, then we might transfer individuals out of hurt’s approach when it is necessary to do it,” Indreiten stated.
Take an journey to Svalbard, Norway in this particular interactive net web page and learn the way local weather change is impacting communities throughout our nation.

Martin Indreiten collaborated on an early warning system to guard the group of Longyearbyen from the threats of future avalanches. His workforce on the Arctic Security Heart constructed low-cost, snow depth sensors that at the moment are deployed on the steep slopes round city. Every gadget sends again lots of of measurements a day, giving security managers higher insights into avalanche threat and when to subject evacuation orders. Indreiten believes avalanche-prone communities around the globe will profit from the expertise developed on Svalbard.
