Iceland’s ice melts quickly, hydroelectric energy technology rises
Melting glaciers are bringing inexperienced power advantages to Iceland, however for a way lengthy?
privateness coverage REYKJAVIK, Iceland — Few international locations can match Iceland in relation to renewable power. The island nation will get almost 100% of its electrical energy from inexperienced sources, and it’s selling using each geothermal and hydroelectric energy.
This makes Iceland a mannequin for the world on find out how to fight local weather change. Satirically, because the world will get hotter, Iceland’s energy grid will solely get stronger.
The explanation? Hydroelectric energy. Or extra exactly, melting glaciers.

Iceland Over 70 percent Half of the electrical energy comes from hydroelectric crops powered by meltwater from glaciers, and because the planet warms and glaciers soften quicker, hydroelectric crops can have extra water to spin their generators and supply electrical energy to the grid — a constructive signal for the nation. Lamenting the decline of glaciers.
“Because the glaciers soften, hydroelectric manufacturing will enhance,” Guðlaugur Thor Thordarson, Minister of Surroundings, Vitality and Local weather, advised E&E Information in an interview. “We’ve every part to develop into a inexperienced power mecca, and that’s our objective.”
Local weather change is already making a distinction.
Almost all of Iceland’s glaciers have been dropping mass because the Nineteen Nineties, resulting in elevated hydroelectric inflows which have been “largely harnessed” by the nation’s electrical energy system. Reportedly Introduced by the European Union.
Locals are additionally conscious of the potential.
“We count on much more water to circulate over the following 100 years,” mentioned Guðmundur Finnbogason, challenge supervisor at state-owned energy firm Landsvirkunde.
“Hydroelectric crops actually produce gold for us,” Finnbogason mentioned throughout a tour of the Ílafoss energy station, about 30 miles from Iceland’s capital, Reykjavik.
However the advantages of energy include two potential pitfalls.
The primary is power waste. A gaggle from the Arctic College of Norway discovered that energy crops at full capability Bypass excess water It is a waste of potential electrical energy.
Vitality Minister Thordarson acknowledged the missed alternative.
“We have been a bit of complacent,” he mentioned. “We have not completed a complete lot within the final 15, 20 years, each by way of hydro and geothermal.”
However, he added, “issues are transferring in a short time proper now.”
The state-run energy firm plans to construct extra generators to seize extra water because of the climate. Glacial runoff is predicted to peak in 40 to 50 years. “We’re investing to have the ability to make the most of the elevated glacial runoff,” mentioned Hórður Arnarsson, CEO of Landsvirkkun. The second, and extra existential, drawback for Iceland is what to do if its glaciers soften. An EU report warns that “little or no of Iceland’s glaciers will stay in 2200.” Whereas it is a bleak long-term outlook, the prediction is consistent with the second, extra optimistic, prediction. Icelandic Meteorological Office Project Rainfall is projected to extend by 1.2 to 4.3 % by the center of this century, primarily because of the results of local weather change. So even when the glaciers disappear, “we will count on to have extra water accessible for energy crops than we had originally,” Landsvirkunde CEO Arnarson mentioned. However extra rain sooner or later is just not sure, and scientists warning that it is troublesome to foretell what the local weather will likely be like in 2200, greater than 150 years sooner or later. Ocean currents For instance, the elements that enhance Iceland’s rainfall might disappear or sluggish considerably by then. This uncertainty is why Þórðarson is contemplating shifting Iceland’s electrical energy grid from a reliance on hydro and geothermal to incorporate wind, photo voltaic, tidal and solar energy. The power of rain“If one thing occurs, and it occurs within the close to or distant future, we at all times have a Plan B,” Þórðarson mentioned. “We won’t put all our eggs in the identical basket.”
