Wind is useful, but not really as base load. There are long lulls sometimes, more than a week. You could run gas peakers but then you haven't fixed anything...

Wind is useful, but not really as base load. There are long lulls sometimes, more than a week. You could run gas peakers but then you haven't fixed anything... Fixing wind lulls requires continent-wide network of wind farms with corresponding grid. Computations suggest best case even 100 GW across Europe. That is nothing compared to demand. (Un)fortunately we have nuclear as a base load option. And fusion as research program. Potentially space solar including space mirrors too.
