You don't you build solar and wind, which have different seasonal productions. Wind power is actually higher during winter. See: https://www.researchgate.net/fi

You don't you build solar and wind, which have different seasonal productions. Wind power is actually higher during winter. See: https://www.researchgate.net/figure/Estimated-normalized-monthly-energy-gain-from-a-wind-turbine-together-with-the-normalized_fig3_320931692 https://www.researchgate.net/figure/Estimated-normalized-mon... And if you combine the graphs for solar and wind from this: https://aleasoft.com/european-solar-and-wind-energy-production-grew-year%E2%80%91on%E2%80%91year-in-october/ https://aleasoft.com/european-solar-and-wind-energy-producti... You can nicely see that they are complementary in terms of energy production.
