Norwegian rivers need to be better protected

When hydroelectric power plants suddenly switch off the water, we risk killing fish fry and other living organisms in rivers. The regulations need to change, say scientists and anglers.

The Alchemists: Turning wild water into white coal

How Norwegian scientists and engineers harnessed the country’s wild waterfalls by developing super efficient turbines — and how advances in turbine technology being developed now may be the future in a zero-carbon world.

Retrofitting dams for more renewable energy in the world

Many of the world’s dams are not used for hydropower, but a new study shows they could be easily altered to produce renewable energy. This would be the most sustainable solution for new energy production in the world, says NTNU Professor Tor Haakon Bakken.

Smart site selection can make hydropower greener

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.

110 years of engineers who built Norway

We often associate innovation with someone who invents something completely new. But innovation is also about improving and expanding on existing technology. One hundred and ten years of Norwegian engineering history provides plenty of examples.

China’s rapid development of solar and wind power

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.

Land under water: Estimating hydropower’s land use impacts

One of the key ways to combat global climate change is to boost the world’s use of renewable energy. But even green energy has its environmental costs. A new approach describes just how hydropower measures up when it comes to land use effects.

One hundred years of producing energy — from water

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.

Helping today’s power companies anticipate tomorrow

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.

ABC — anything but coal

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.

A Third Industrial Revolution for Norway

Norway’s wealth and prosperity over the last four decades has been built on oil, but Jeremy Rifkin, a futurist and social and economic thinker, says it’s time for the country to change. The Third Industrial Revolution is coming, and Norway needs to abandon fossil fuels and move towards a greener future that relies on renewable energy, shared transport and ultra-efficient housing.
