We can do a lot to save the climate by switching from coal to natural gas. And we can shelve concerns about the negative climate impact of methane emissions from gas production, say researchers.
Energy and environment
The discharge of pharmaceutical drugs is a major problem around the world, but a new study of the freshwater fish burbot shows that there is hope.
Grocery stores throw out 75 000 tons of food annually. By adding date tagging to the barcode, food waste could be dramatically reduced, say two NTNU students.
The arctic archipelago of Svalbard is already experiencing dramatic effects from climate change. A new study shows how these changes can force wild reindeer to graze on seaweed, a strategy that increases their likelihood of survival— and is recorded in their poop.
According to a new report, many years of research effort have resulted in significant reductions in the cost of full-scale carbon capture and storage.
It’s springtime in much of the northern hemisphere, although spring snowstorms are still possible. When that happens, salt trucks and ploughs help make roads safe. But road salt can be bad for the environment, and can rust cars, bicycles and other metal. New research shows that salt use can be safely — and substantially — cut in certain circumstances.
A sixth of all emissions resulting from the typical diet of an EU citizen can be directly linked to deforestation of tropical forests. Two new studies shed light on this impact, by combining satellite imagery of the rainforest, global land use statistics and data of international trade patterns.
Ecology professor Sandra Myrna Díaz is the winner of the 2019 Gunnerus Award in Sustainability Science.
Moreover, researchers have succeeded in increasing its output dramatically by providing the panel with its own cooling system.
What is the best timing for the various hydroelectric plants to produce power? NTNU and SINTEF have developed an efficient and profitable simulation tool to make the most of hydropower generation.
A snake robot will soon be relieving divers and mini-subs in the North Sea. But first researchers have to test its mettle in the Trondheim Fjord.
Better and cheaper offshore wind farms are the goal for a new cooperative effort on renewable energy.
When China sets its sights on a goal, the country can change at a blindingly rapid pace. Now the country is focused on innovation and technological innovations, with renewable energy at the forefront.
If carbon dioxide concentrations in the atmosphere and in the ocean continue to rise, this could fuel the mass development of toxic algae, with far-reaching consequences for the pelagic food web, an international team of researchers has found.
Several countries are warning of massive insect deaths. Right now we don’t know how matters stand in Norway. But that’s about to change.
Climate change in the Arctic means more winter rain, and consequently more rain falling on snow. The result can be a buildup of ice under the snow, which can wreak havoc with arctic ecosystems.
Cement manufacture accounts for as much as seven per cent of global greenhouse gas emissions. A new hybrid technology makes it easier and less expensive to capture and purify CO2 produced by the industry. And the technology can be retrofitted to existing plants.
Three new fjord laboratories, one in Trondheim, one in Hitra/Frøya and one in Ålesund, along with two test basins in Trondheim are planned as part of the project.
New technology will be used to recycle rare and valuable metals from waste materials such as electronic scrap and foundry slag. The process is profitable and may help to reduce environmentally harmful mining operations. The method is now in the final for the EU-research prize “Best early stage innovation 2018.”
As much as 20 per cent of jet fuel burned in Norway in 2030 could be biofuel made from the country’s forest residues. This alone could cut greenhouse gas emissions from Norway’s aviation sector by 17 per cent.
Our carbon emissions are much higher than are needed for us to have happy, healthy lives. But cutting these emissions requires us to think differently about how we measure growth and progress.
NTNU researchers wanted to see if labelling products and putting up signs in stores would encourage more consumers to buy sustainable seafood. The results showed that customers bought significantly more seafood generally – including options that were not sustainably harvested.
Electric cars are good for the environment – but not for people who cannot see. They have problems detecting the silent vehicles. However, Norwegian research scientists are working on a solution.
