If Europe can continue to buy cheap Russian gas and oil and use it as they have done in the past then 5x as much solar and wind for 2025 sounds great. That was the Great Plan of the green movement in Germany. In 2010, 2020, 2030, 2040, 2050 or a time after that green hydrogen will become cheaper than Russian gas and oil and then this plan will be completed.
If however Europe can't continue to burn gas and oil when demand exceeds supply because of the weather, then there is a major problem that is going to need fixing in a very expensive and time consuming way. If green hydrogen don't drop in price and no other storage solution can arrive to become cheap than gas and oil, then the climate change goals won't be achieved.
To add to the problem in northern Europe, the locations for hydropower is practically already at maxed utilization. They are also quite old and with large maintenance debts. They are also is causing extinction of several species, and fixing that would cost prohibitively much money, and the solutions will reduce outputs.
The thing is, 5x solar and wind sounds great but if I can specific the time and space for it, I would make a great profit of trading 5 units of energy for 1x at a different space and time. The price difference in northern Europe can be a factor of 10 or even higher between low and high. 5 kwh worth 3 cent each is worth much less than 1 kwh worth 40 cent.
