The thing is, many houses (like my own) aren't insulated very well still. Also, you can't look at production and use over a month. We often have multiple cloudy days in a row where we produce next to nothing in comparison to what is used. So you need something to bridge those days. We do have wind and off-shore wind is relatively reliable, so that's good.

Solar is just awful for our climate, since we produce most when we use the least, which you can see in the quite extreme negative prices for electricity we've already seen this year... And it's not even summer yet.
