Do you only use electricity only some hours a day?

No it’s usage need to be constant, or you'll get black-outs in regions where the grids 50hz frequency cannot be kept - which a lot of communals in Sweden are dangerously close to.

And if you don't keep the network balanced, you'll get complete blackouts instead of regional blackouts.

Well, speaking for myself, I do use different amounts of electricity during the day. As does everyone in my region. And your region, probably.

But you want to be able to use electricity when you need it, right?

That's not what I'm saying. On a windy day, then doubling your number of wind turbines will (roughly) double your power output. But if there's no wind, your output drops to zero. Contrast that with nuclear power, where doubling capacity doubles output always.

So with nuclear power you could say that based on what current output we have, if we build X more capacity we could retire all polluting energy sources.

With wind (say) you can't say that.

So, you're saying that if we adopt a stupid wind policy, bad things will happen?

I'd agree with that. Have you considered adopting a good policy instead?

If you read my comments you'll see what I said, which is that such percentages are misleading. Not sure what's causing your newfound silliness.
