they plan to adopt a similar off—grid system in longyearbyen, but on a bigger scale.king into what could come after that. solar could be a very good thing for the summer part of the year, and then you would need something else for the rest of the year. it's about using a hybrid system, combining different energy technologies. and there lies the big challenge. this is our energy transition pilot facility. and it's all monitored remotely. here we can see, for instance, how much solar energy we have produced. and, as you can see, they've just been operating a few hours throughout the day. so it's mostly solar energy that's been providing the station for the last 2a hours. they plan to adopt a similar off—grid system in longyearbyen, but on a bigger scale. what could come after that. of the year, and then you would need something else for the rest of the year. energy technologies. and there lies the big challenge. scientists are also exploring how well wind works in extreme cold. and here, they're testing geothermal. we have a thinner crust of the earth here, so it's actu
