Iceland’s Ice Is Melting So Fast That It is Boosting Hydropower
Melting glaciers are creating a environmentally friendly power windfall in Iceland—but for how lengthy?
CLIMATEWIRE | REYKJAVÍK, Iceland — Number of countries can contend with Iceland when it arrives to renewable energy. The island country will get virtually 100 percent of its electric powered electricity from green sources, and Iceland has championed the use of the two geothermal electrical power and hydroelectricity.
That makes the state a product for a world seeking to combat climate alter — which is ironic because Iceland’s electric grid is only going to get more powerful as the globe will get hotter.
The purpose? Hydroelectricity. Or more exclusively, melting glaciers.

Iceland receives a lot more than 70 p.c of its electricity from hydroelectric stations fed by glacial meltwaters. So as the Earth heats up and glaciers soften faster, hydroelectric stations will have more h2o to spin turbines and power the grid — a silver lining for a nation mourning its glacial decline.
“When the glaciers melt, then it will be extra output from hydro,” explained Guðlaugur Þór Þórðarson, minister of the Ecosystem, Strength and Weather, in an job interview with E&E News. “We have anything to be the mecca of inexperienced electrical power, and which is what we want to do.”
Local climate alter is currently making a variation.
Virtually all of Iceland’s glaciers have been shedding mass due to the fact the 1990s, and that’s led to an increase in hydro influx — a improve that the country’s energy program “has been generally ready to make use of,” according to a report launched by the European Union.
Locals see the probable, much too.
“We are anticipating much more for the subsequent hundred a long time — additional drinking water flowing,” stated Guðmundur Finnbogason, a venture manager with Landsvirkjun, the nationwide electric power business.
Hydro stations are “literally producing gold for us,” claimed Finnbogason all through a tour of the Írafoss Power Station, which is about 30 miles from Iceland’s capital Reykjavík.
The boon in electrical power, however, arrives with two opportunity pitfalls.
The initially is squandered electricity. A group from the Arctic College of Norway cautioned that at-ability stations have been bypassing extra water and throwing absent potential energy.
Þórðarson, the energy minister, acknowledged the missed prospect.
“We’ve got a little bit complacent,” he explained. “We have not done that a lot when it arrives to both of those hydro and geothermal in the previous 15, 20 several years.”
But, he added, “now points are going quite rapidly.”
The national power organization ideas to build far more turbines to seize the weather-pushed water surplus. Glacial runoff is anticipated to peak in about 40 to 50 decades.“We are performing investments to be equipped to harness this maximize of movement from the glaciers,” stated Landsvirkjun CEO Hörður Arnarson.The 2nd — and far more existential — dilemma for Iceland is what to do when its glaciers have melted absent.The EU report warns that “almost no Icelandic glaciers will be still left in 2200.”It’s a bleak prolonged-term projection, but the expectation is matched by a next — and additional optimistic — estimate.The Icelandic Meteorological Business assignments that precipitation will increase by 1.2 % to 4.3 % by the center of the century, mainly owing to the results of local weather improve.So even if the glaciers disappear, “we can be expecting additional h2o coming to the power plants than we did in the starting,” explained Arnarson, the Landsvirkjun CEO.But that wetter future is much from a supplied, and experts warning it is tough to forecast a 2200 local climate extra than 150 yrs absent. Ocean currents that improve precipitation in Iceland could be long gone or drastically slowed by then, for example.The uncertainty is why Þórðarson desires Iceland to diversify its grid from hydro and geothermal reliance to include things like wind, and probably photo voltaic, tidal and rain electric power.“If something comes about, and it will take place in the in close proximity to or distant potential, then we always have a Plan B,” Þórðarson stated. “We can not put all the eggs in the similar basket.”
