You're comparing the price of an energy that is non-drivable (wind) to one that is (nuclear).
Non-drivable energy sources cannot stand on their own. People also want electricity in the evening when there's not enough wind or on a cloudy day.
The fact that the energy produced is not drivable must be factored in the €/MWh otherwise you're comparing apples to oranges.
Also, consumers have to pay (through a tax on the utility bill usually) for periods when renewables produce too much.
See negatives prices in Germany [1] or Britain paying windfarms owners more than £1 million a week to shut their production down [2].

- rakoo 7y agoAnd when you compare comparable things (ie same output 24/7 for the same duration), drivable solar and wind are not only more expensive, they also emit more CO2. This trend of replacing nuclear with unreliable intermittent energy is dooming us all.
- imtringued 7y agoIf there is a trend, then fix the cause.
- simonebrunozzi 7y agoReally? Why would they emit more CO2? Can you expand?
- simonebrunozzi 7y agoSorry for the dumb question, what is "drivable" energy?
- ElKrist 7y agoEnglish is not my native language so there might be a better word for what I meant: An energy that can be "produced" (physically transformed is more accurate) whenever you want and at whatever power you want (with the upper bound of its max power obviously). In practice there is no such energy: there is always a delay between your choice of delivering a certain amount of power from a hydroelectric dam, a nuclear plant or a coal plant. Some behave better than others in this regard. However with this delay taken into account, you can schedule production according to estimated demand. With pure renewables without a large storage system this is not possible. Please note that "drivable" energies also need some storage (hydroelectric dam for instance) to help balancing the production/demand. However it is marginal
