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.

Two hundred and seventy-eight wind turbines won’t cut it

The transition to green energy hasn’t really begun, according to Associate Professor Espen Moe. Even though the 278 new wind turbines that will be built in central Norway are an important investment, it’s not nearly enough, he says.

Norway can be Europe’s green battery

Norwegian hydropower could make Norway the “green battery” of Europe — not by building new power plants, but by further developing those we have.

Preventing hydropower turbine failure

The turbines at the heart of Norway’s many hydropower plants are in trouble. They can’t handle the new, flexible power production regime.
