Further south in Germany, where it is getting more mountainous, as well as in several other countries (USA included), they have built huge artificial dams in the hills. At nighttime these are being filled from a lower reservoir by electric pumps utilizing the surplus electricity from wind power, nuclear power, coal and oil power plants. At daytime, when all the power is needed, the dams are emptied through water turbines to the the lower reservoir. This is a local/regional alternative to ship electrons back and forth across the North Sea.

If you do the math, you'll see that it takes huge amounts of water to produce a thousand kWh. Or, the water must be lifted to a great height: If you collect it as rain at 1500 meters above sea level, it represent 15 times as much energy per cubic meter as you get by pumping it up to an artificial dam 100 meters up. So those pumped hydro power stations do not have sufficient capacity to save energy from one season to another, only from nighttime to daytime.

(We certainly have huge artificial dams in Norway as well - take a look at Vatnedalsdammen[^], and notice the fellow standing at the foot of the dam. The water surface is roughly 800 m above sea level and dam capacity is 1.15 billion cubic meters.)
