It sounds like something out of a bad science fiction movie — artificially blocking sunlight to keep global warming from overheating the Earth. Nevertheless, a small cadre of researchers is studying the option — so that if humankind ever needs to use it, it will be an informed decision.
An old building at Tullinløkka in Oslo has set a new standard for reuse, consisting of components from other buildings – like concrete floor dividers from a government building. Building stock in Norway accounts for half of society’s total environmental impact. Thinking in new ways and reusing building components offers multiple gains.
Large cost cuts are achievable for both floating and bottom-fixed wind farms in the future. If we do this correctly, floating wind turbines will be able to compete with bottom-fixed wind turbines by 2030.
Relatively simple adaptation could make the cargo ships of the future completely green. The technology is based on the chemical compound ammonia, some extensive number crunching and one or two engine modifications.
The sun shines just as much out at sea as it does on land. There are also no restrictions on area use and seawater even helps to cool the solar panel technology. It’s only a matter of time before the first floating solar energy farms are installed at sea.
Disposable products are bad. But durable goods account for two-thirds of the global household’s energy footprint.
Solar cells that use special dyes to collect light could one day be integrated into buildings. Researchers at NTNU are trying to find the best dyes for the job.
Metal production generates considerable emissions of greenhouse gases. But the type of ore used in production can make a big difference.
Ten cubic kilometres of concrete, equivalent to the volume of Mount Everest, are used in construction projects every year, resulting in huge volumes of emissions. But a new eco-friendly cement may help to reduce our global climate footprint.
New discoveries are making silicon production cleaner, and solar cells of the future will become even more environmentally friendly.
If global warming happens too quickly, not all species will be able to adapt in time.
NTNU and SINTEF will be partners in the newly funded FME NorthWind research centre, which will develop competitive offshore wind farms within ten years.
The EU has awarded two million euros for research on how animals are coping with climate changes.
Emissions from the production of materials like metals, minerals, woods and plastics more than doubled in 1995 – 2015, accounting for almost one-quarter of all greenhouse gas (GHG) emissions worldwide. Material efficiency needs to play a larger role in climate planning, a new report says.
The capture and storage of CO2, also known as CCS, from our waste is essential because this refuse is responsible for a large proportion or our cities’ greenhouse gas emissions. Moreover, the technology represents a relatively inexpensive abatement cost.
The search for the perfect solar cell is not yet over. Norwegian researchers are now adopting a new approach to the cells’ raw material, crystalline silicon, with the aim of making the electricity-generating cells even more efficient.
Tired of people claiming that the climate crisis isn’t real? You’re not the only one. This is why they are wrong.
NTNU researchers are playing a leading role in a new IPCC report. One way they’re helping is collecting data on a website created and operated by the university.
A unanimous group of research scientists are convinced that kelp may share many of the applications of soya and oil, and that they can also be used to capture CO2. Seaweeds can contribute towards climate-friendly solutions in all sorts of contexts. New know-how about seaweed farming is currently accelerating industrialisation of the sector.
Droplets and bubbles are formed nearly everywhere, from boiling our morning coffee, to complex industrial processes and even volcanic eruptions. New research from SINTEF and NTNU in Norway, improves our understanding of how these bubbles and droplets form. This could improve our ability to model climate change.
The coronavirus outbreak raised everyone’s awareness of the significance of global supply chains to modern economies. But global supply chains also play an important role in greenhouse gas emissions. How they are managed can either increase or decrease carbon emissions, new research shows.
As nations prepare to mitigate climate change, decision makers need to understand how land use fits into the climate equation. A new study looked at land use changes over two decades and found a major shift from cropland to forests. That change made western Europe cooler.
Chinese authorities are investing heavily in green energy. The country has become a world leader in solar and wind power. This rapid expansion was made possible by the approach taken by authorities.
Organic solar cells are usually less effective than silicon solar cells. But there is still a market for them – and they’re beautiful and exciting.
