  6.  @geroldfirl  Norway has a storage capacity of 85 TWh already in our reservoirs... Northern Europe only needs 25 TWh. The problem isn't storage capacity of the reservoirs. We lack pumping stations and power transfer infrastructure. We need power transmission through superconductors I think... As well as more high capacity energy transfer in general. Just in general we need a lot, and I mean a lot of investments. In total the EU has a demand through the year of 2 794 terawatt-hours through a full year. So essentially Norway has the storage capacity in existing reservoirs of 1/33th of EUs yearly energy consumption. But remember that it's unlikely that the EU has zero energy production. So mixing a reduced production with our storage capacity should allow our stored energy to last long enough to smoothen out the swings in energy production. But yes, the Alpes will help. :-) But yeah, when there's excessive rain our energy prices actually goes negative as we have to release water in order to avoid collapse of our reservoirs. So that can make hydrogen production viable. On the whole I think it's possible for Norway to store enough power between pumped hydro and hydrogen production to keep the EU running for a couple of weeks even without any other energy production on the continent, and in a more realistic scenario with help from the Alps and some energy production I suspect that we can handle a month together as a continent between pumped hydro and hydrogen. We would still occasionally run out and need natural gas etc, but it should be possible to manage with extremely low amounts of that. Although the electricity prices when that happens would need to be really high. Doesn't mean we always would have that kind of energy stored of course. There needs to be enough price differences etc to make that viable. But yeah.

  7.  @geroldfirl  Yes, not enough for a long duration without power and of course if there's a draught and evaporation that energy is lost... But Norway is essentially just a mountain chain. So yes, in theory provided enough investment Norway should be able to power the EU for about 12 days if starting from absolutely full in every single reservoir, using pumped hydro only if my calculations are correct. Add hydrogen and we can probably add a little more capacity at times when power prices are low enough. Although I don't know how much hydrogen production is economically viable here (I know that it would pay to make some when our reservoirs are dangerously full if Germany starts importing hydrogen for their gas power plants, but I'm not sure if it would be profitable to import power to make much hydrogen, my guess is that at least in the beginning hydrogen might be mixed into natural gass or something like that rather then used separately) That said, power transfer infrastructure is severely lacking. When the war started and energy prices skyrocketed reservoirs in southern Norway was emptied to supply Europe with power, then we had shortages ourselves there and we where actually exporting power in northern Norway into Sweden while importing power into Norway in southern Norway paying far more for said power because we don't have the infrastructure to really transfer power through the country. The infrastructure mainly supplies major cities and urban centers from power generation in the periphery. But it operates kind of like multiple smaller grids only loosely with each other with fairly limited transfer capacity. Norways power transfer capacity is mostly going in a east-west direction allowing us to compensate for shortfalls in domestic production with Swedish power and well of some of our surplus to Sweden. While the Swedes actually have invested in power transfer capabilities going in a north-south direction, allowing them to function as a hub for energy trade between Denmark, Norway and Finland (and I think other countries like Estonia as well).

  9.  @geroldfirl  Actually, 100% renewable isn't that hard for Europe. Part of the plan is for Norways hydropower plants to function as energy storage, by pumping water from lower reservoirs to higher ones using excess energy when there's a lot of wind and sunlight. We're also planning on producing hydrogen that can be burned in hydrogen/natural gas hybrid power plants. A lot of energy is wasted but this approach allows the utilization of existing infrastructure during the transition period. 89% of Norways electricity comes from hydropower. And we also got produce quite a bit of wind energy and even a little bit of solar etc. In total 98% of our power is renewable right now (varies from year to year depending on precipitation, wind, sun, etc, some years we import a lot of coal, gas and nuclear power from abroad) In a dry year we'll still need other sources of energy, and I'm sure that part of the reason why Germany wants to burn hydrogen in gas power plants despite the wasted energy is to allow them to switch to natural gas again in bad years, or mix it together with the hydrogen. Just in case. As for the cars... 80% of the cars sold in Norway are EVs, not plug in hybrids etc, just pure EVs. With other electrified vehicles making up a significant part of the rest. And EVs makes up a third of all existing cars in Oslo, our capital now from what I understand. Germanys problem is underinvestment in EVs and too much focus on diesel cars for too long. And the country now has to catch up. Anyway, all Europe needs to manage with renewable energy is to build out our grid from northern Norway to Morroco and from Ireland to Ukraine, and Finland. And to build energy storage, like pumping stations in Norway. Er already have the reservoirs available that can be used for the energy storage. We're also building windmills, battery banks and hydrogen production facilities in Norway. We fully intend to keep exporting energy to the continent after the transition as well as function as a battery for Europe. The transition in question is already underway.
