Another point to consider besides @Mister44’s very valid points is that places with some of the highest solar and wind generation percentages (Germany, Denmark, Spain) but no widespread geothermal or hydroelectric (so not Norway or Sweden) have incredibly high retail electricity prices.
Why does increasing the proportion of wind and solar increase the retail prices of electricity if they are 1) heavily subsidized and 2) cheap? The obvious answer would be the hidden costs of intermittency that people keep banging on about. It’s also important to note that none of the studies showing 100% renewable power is plausible predict this increase in prices, so they’re probably leaving out some crucial details about implementation.
