Some misconceptions from the Greens

I know what I’m writing here is heresy. At least it is for the supposed to rule us well deledefs in Germany. Anyway here we go

Now can we rely on actual an currently working renewable energy? Well the depressing answer is “no”. We can’t . Neither wind nor sun is guaranteed to work every day, every hour. So we always will have strong up-and-downturns. There is not denying there are those gray days where neither one see the sun nor feel the slightest movement of air. And there will always be those day where the sun is burning and the wind storming.

Can we follow this variability. I’m afraid that won’t work either. So no we simply are not that variable with our needs.

So what can we do then? Can we store the electricity. Well to depressing low level yes we can. It might work e.g to keep my computer running with a large enough battery which may keep the currency even for a week or so. Can we do the same for let’s say melting steel? Well no, there is not way of storing away big masses of energy. Yes agreed you can warm water with it and you may use this water to make electricity again. But this really is a big loss and currently nothing on a large scale is available.

So the current unpleasant but nonetheless truth is. We have no reliable way storing away electricity. That’s a simple fact of life which nobody can change immedieatly, so currently if we’d have 100 GW renewable energy we need another 100 GW “traditional” energy, be it gas, coal, oil, nuclear power. So this means we have a need for double the needed energy just in case one half is not available. That is uneconomic to the highest extend, so do we keep all the other conditions the same and let us assume one 1 KWH costs 20 ct. Then we need double the price for one KWH just being able to satisfy our current need for currency.

The other option just can’t be needing half the energy. But that does nor work for electricity. So with all mean the Greens are working against the objective reality, and how should that work? The simply answer is it hadn’t, doesn’t and never will (long term) So either we find a way storing electricity or we must limit other outputs from the industries which have to “be” the reserves. In both cases we need at best double the prices of today. And you can bet hardly anyone will jump on the idea having double his expenses for the same output just because the Greens ignore reality
