Also please take into account the quality of the infrastructure itself, which will add some cost. I so often hear about brown-outs and blackouts in the US. That is essentially unheard of in Germany. The productive hours lost also should be factored in, plus the required backups that having an unreliable supply necessitates. So I doubt very much that the difference is as stark if the total costs are taken into account.
Can you quantify those costs? I've had one blackout and about a dozen momentary outages in 14 years. A trebling of my electric bill with a minor improvement in reliability would not be worth it.
The US is much larger than Germany and has a much larger population. For example, California alone imports twice as much electricity as Germany produces via renewables. Each state has numerous utilities with varying ages of equipment, so delivering power to so many over such a large area will necessarily have problems.
Presuming you are in Germany, has this been resolved:
In a stunning admission, the German Government recently announced that its transition to Renewable Energy was, “On the Verge of Failure.” This blunt statement was released by Germany’s Economic Minister and Vice Chancellor to Angela Merkel, Sigmar Gabriel at an event at SMA Solar… Germany’s leading manufacturer of Solar technology.
