Nuclear power causes least damage to the environment
A comprehensive analysis of 870 power plants worldwide shows that nuclear power is a clear winner in protecting ecosystems. Bioenergy is a sure loser.

The ice in Antarctica has melted before
The ice sheet in Queen Maud Land in East Antarctica is not stable. Large amounts of ice have melted in the past, most recently as 5,000 years ago.
Prestigious EU support to save species
An NTNU professor has been awarded an ERC Advanced Grant to investigate how species can survive a changing environment.
An artificial lava for sealing oil and gas wells has passed its lab tests
Norwegian oil and gas companies are now plugging and abandoning production wells using an artificial ‘lava’. So far, the results have been excellent. Recent laboratory results indicate that the same method can be used to seal subsurface CO2 storage reservoirs.
Southern Sámi language in danger if reindeer herding is restricted
Wind turbines are contributing to the Southern Sámi losing grazing land for their reindeer husbandry. This livelihood is central to the identity of the Southern Sámi culture and thus to their language, researchers say.
How researchers halved a bed’s carbon footprint
Researchers calculated the total carbon footprint of a bed. Then they discovered it was possible to halve it.
Smarter charger pricing offers effective emergency aid to the power grid
The Norwegian power grid needs relief during periods when ‘everyone’ is using electricity. Research is showing that variable pricing for the fast charging of electric cars may offer a solution.
Builders rush to learn from the ZEB lab showcase
The ZEB Laboratory has been utilised both as an office building and a sustainable construction laboratory for about two years. It was designed to be the world’s most ambitious ‘climate-adapted building’ and up to now it has been a great success.
Moose can play a big role in global warming
Climate researchers have long known that large animals, like moose, could play a role in how much the Earth will warm due to climate change. But the question is, how much? New research shows the answer can be a lot.
New concrete from old buildings
Christian John Engelsen at SINTEF is teaching the world to recycle demolition rubble to make new concrete. Anything and everything can be recycled, he says. What takes time is getting people on board.
Green production of silicon is just around the corner
“We see no technical obstacles to being able to produce silicon without CO2 emissions within the next two to three years,” says Maria Wallin at NTNU.
Reducing your electric bill with a predictive control heating system
NTNU has tested a system to predict the heating needs on the Gløshaugen campus. The results show that we can save even more where surplus heat is already in use.
A new approach to waste incineration removes CO2 from the atmosphere
There are plans in Årdal to build a waste incineration plant based on a new technology that captures and stores CO2, thus removing the greenhouse gas from the atmosphere.
Energy crisis can help boost green energy investments in Europe
Can Europe use the energy crisis to help accelerate its efforts to achieve net zero greenhouse gas emissions by 2050? The EU’s Scientific Advisory Board on Climate Change says yes.
Urgent need to commercialise CCS
At last it is now possible to capture CO2 at industrial scales without state subsidy, and countries across the world should be persuading private industry to identify storage sites that will make a real difference.
Blue hydrogen: the real bridge between fossil fuels and renewable energy
Blue, also called “low carbon” hydrogen will make for a much more suitable transition towards renewable energy than natural gas.
Data-driven heating reduces energy consumption in buildings
Energy consumption in buildings can be reduced by predicting their actual heating needs.
Recycling snuff boxes to make new products
Don’t tell me that you haven’t noticed them. Empty snuff boxes littered all over our streets and parks. But instead of being just rubbish, they can now be recycled to make new products.
Just one degree can change a species
Even seemingly small changes in the climate can change the number of animals and plants in an area and how species behave, new research shows. Natural history collections provide valuable insights.
Now is the time to stop talking up the benefits of natural gas
The view that natural gas can act as an eco-friendly bridge in the transition from our use of coal to renewable energy has experienced a renaissance in the wake of the European war. Thus, the time is right to review the data behind the politics.
A gamechanger for aluminium component production in the car industry
A new Norwegian technology is enabling the removal of an entire process stage from car component production lines. It makes the cars less expensive, more eco-friendly and faster to manufacture.
Enzymes from bacteria and fungi break down plastic
Plastic is useful but also poses an environmental problem. Scientists are now using enzymes from bacteria and fungi to break down plastic.
Eavesdropping on the Earth itself
This summer, a coalition of researchers led by the Norwegian University of Science and Technology reported the first-ever use of a fibre-optic cable network to eavesdrop on whales in the Arctic. Now they suggest these networks be used to establish a low-cost global ocean-earth observatory.
In search of a smarter grid
The Norwegian government is committed to reducing greenhouse gas emissions by 55 per cent by 2030. This will involve dramatic changes to the electricity grid system.
