A new report from the Intergovernmental Panel on Climate Change (IPCC) describes with unnerving detail just what can happen if nations fail to limit greenhouse gas emissions. But rapid international action will keep the worst consequences at bay, the panel said.
Even though new hydropower dam developments are intended to provide green energy, they can drown areas that are rich in plant and animal species. But this kind of collateral damage can be limited by strategic site selection, a new study shows.
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.
Hauliers Asko in Norway, are among the first in the world to operate a goods vehicle that runs on hydrogen made from solar power – thanks to a collaborative effort by research scientists and other players.
Offshore wind energy is seeing renewed wind in its sails as a major industrial opportunity for Norway. But researchers warn that economic and political players could hinder this development if they get locked into the existing industrial structures.
The Norwegian company Arbaflame is intent on persuading the world to abandon polluting coal power. The new technology makes it possible to replace coal with eco-friendly wood pellets.
Renewable energy is fine, but often it’s needed at times other than when the wind is blowing or the sun makes an appearance. The energy needs to be stored – and a new method is on the horizon.
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.
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.
Thanks to toxin-free technology that also saves energy, Norwegians can eat their ice cream without worrying about the climate.
When China wants to exploit its hydropower resources, they can ask Norwegian researchers for advice. It is now possible for hydropower companies in China to read the handbook for environmental design of regulated rivers in their own language.
Norwegian research scientists are contributing to the development of the world’s hottest geothermal well in a non-volcanic area. The goal is to exploit the inexhaustible supply of heat from the interior of the Earth, and this calls for equipment that can withstand the most extreme conditions.
Experiments in SINTEF’s climate lab demonstrate that solar cells work very effectively in Norway in spite of the rain and cold. But there is one thing that owners should be aware of if they want to get the most from the sun’s energy.
The 1969 discovery of oil at the Ekofisk field in the North Sea transformed Norway into an internationally important energy nation. But long before black gold was being pumped from the Norwegian Continental Shelf, Norway’s economy was fuelled by a different kind of energy: hydropower.
Most efforts to control ice build-up on structures like wind turbines and solar cells involve creating a surface that repels water. But Norwegian researchers have engineered a different approach that allows ice to form on a surface, but then causes it to crack off.
Heavy-duty trucks will soon be driving around in Trondheim, Norway, fuelled by hydrogen created with solar power, and emitting only pure water vapour as “exhaust”. Not only will hydrogen technology revolutionize road transport, it will also enable ships and trains to run emission-free.
Researchers rely on super microscopes to develop more efficient next-generation batteries.
Longyearbyen, the world’s most northerly city, could save more than 100 million kroner (11.5 million US dollars) a year in the cost of electricity, if a completely green hydrogen-fuelled power station is built in preference to laying a cable from the mainland, according to calculations made by SINTEF scientists.
In a few years we’ll be able to charge virtually wherever and whenever we want with only minimal buildout of the power grid, according to electrical engineering professor Magnus Korpås.
Researchers have established a technique that will help ensure a stable supply of electricity even as new renewable energy sources come on line. The trick is helping all of the subsystems to work in concert.
It’s not easy for big, profitable companies to respond to huge technological changes. One NTNU researcher hopes to help Norway’s electric power industry cope with the market challenges from renewable energy and changed consumer behaviour.
Research shows that fitting tyres with very low rolling resistance, combined with the right road surfacing, can provide just as much noise reduction as traditional noise barriers.
Policymakers, industry and government officials will have to invest US $2.5 trillion for electricity generation over the next 20 years. A new report presents the environmental costs and benefits linked to different renewable energy sources, and makes one thing abundantly clear: anything is better than coal.
