To completely electrify Norway’s power system by 2050, we subsequently solely want a tripling of the wind power we have already got, plus a quadrupling of photo voltaic power in comparison with the ambition set by the federal government and the Storting for 2030. there might be a small, pure enhance in hydropower.
Technically, it is a manageable job that can yield 75 terawatt hours (TWh) per yr of latest electrical energy manufacturing, for a complete of 225 TWh.
With 150 TWh of hydropower on the backside, some extra internet and clever administration, this turns into a robust and dependable power system with low electrical energy costs.
On the identical time, we should use power extra effectively, keep away from pointless progress in power consumption and section out all use of fossil fuels. It is more durable, but it surely’s the entire level of the inexperienced shift.
This answer is only one of many attainable options. There isn’t a conclusion, however the decisions we make now are decisive. Politics is below assault from all sides, and the confusion leaves loads of room for many who need to delay and sow doubt about renewable power from wind and photo voltaic. It may result in decisions – or coaching – which can be unlucky for Norway.
Because the Worldwide Vitality Company (IEA) exhibits in its latest World Vitality Outlook 2023, photo voltaic and wind power are important for the worldwide power transition. Norway has significantly good situations for wind power, however photo voltaic power can also be doing properly. Norway has one of the best situations for a completely renewable power system.
Fossil power dominates the worldwide power system. The way in which power is usually counted is customized to this power supply. This has plenty of unlucky penalties, together with that it isn’t clear sufficient how inefficient the present power system really is.
The article continues under the commercialThis provides to confusion.
The power service, or ‘helpful power’, is what you get out of the power system divided by the power you set into it. Figures from the Lawrence Livermore Nationwide Laboratory present that for the US, power service is just a 3rd. The remainder is ineffective warmth loss to the surroundings.
No nation has the identical power combine and power service calculations range, but when we assume that the world as a complete is doing barely higher than the US, then we will anticipate that about four-tenths of the power put into the system used as an power service.
Taking the power service to be supplied as a place to begin generally is a catalyst for brand new pondering and innovation, as a result of it adjustments the premise of the power debate and subsequently the way in which we predict.
In a future all-electric power system, the effectivity price may very well be near 80 % or higher, from {the electrical} power produced to the power companies carried out.
The article continues under the commercialWhich means that 50 models {of electrical} power are sufficient to exchange 100 models of the power put into the present fossil fuel-dominated system.
The problem dealing with the world is big, however a lot smaller than one would possibly get the impression from present power statistics, tailored to the fossil age. By as an alternative producing simply half of in the present day’s power enter as electrical power from zero-emission sources, we will obtain the identical degree of power service, however with minimal greenhouse fuel emissions and no air air pollution.
That’s the reason electrification with zero-emission sources is so essential. It’s not ‘extra of every part without delay’, because the Vitality Committee sadly put it, it’s ‘reaching extra with much less’.
Due to hydropower, Norway has come a good distance in electrification, and we’ve got a neater job than most international locations. Of the 220 TWh of home ultimate power consumption in the intervening time, roughly 130 TWh is already electrical. The remaining 90 TWh consists primarily of refined fossil fuels with poor effectivity. This 90 TWh can subsequently get replaced by 60 TWh {of electrical} power, or much less, since we have to preserve biofuels and waste.
Extra electrification of oil and fuel extraction and Melkøya would require one other 15 TWh – which can however be a surplus as soon as we section out all fossil fuels.
The 75 TWh enhance is properly inside what we will obtain with light onshore wind and photo voltaic growth, as we’ve got progressively discovered with land-intensive hydropower.

There’s additionally room for additional progress because the inhabitants grows.
In any case, we don’t have to complicate issues with costly and problematic nuclear power or floating offshore wind for consumption in our personal nation with few inhabitants, massive areas and loads of hydropower on the backside, despite the fact that these are globally essential options.
