IMO countries that decided to pursue green energy at all cost have shot themselves in the knee and this wasn't done willingly. Many countries opposed this but were forced into submission by the EU council that kept reducing their CO2 emission limits. In other words, the EU put its members in a crisis situation.
Incorrect, because 1) nuclear energy, which you mention, is viewed as "green" by the EU, and 2) the problem lies in the natural gas prices, and renewables are driving down them, but the installed power in most countries is not enough.
All over twitter and reddit there are stories of many small and medium type of businesses closing due to electricity costs. At first when the costs went up, they increased their prices, and then they went up again, and there was no point in increasing prices because nobody would buy a 20EUR cup of coffee.
I think you're in principle right but greatly exaggerating here.
You cite the example of a restaurant/coffee shop, but energy/electricity isn't the main cost of this kind of business, so even if electricity costs triple, they don't have to increase their prices _that_ much. However, there are definitively industries, for example aluminium production, which are suffering a lot in the present conditions in Europe.
Unfortunately this is nothing more but the system trying to find some sort of equilibrium, and only businesses which find a way to be more efficient are going to survive.
Good point with the equilibrium. Some businesses will most certainly close; the recession could be as deep as in 2008/09, even deeper if the situation in Ukraine extends in time. But I guess many will also see new opportunities to increase efficiency in a scenario where energy is more scarce and expensive.
We can compare that to the way the Bitcoin difficulty works. If electricity prices rose in the whole world, and all other constants were equal, then there would be less profitability, until all unprofitable miners cease mining; but after the difficulty adjustment, for the rest of the miners the profitability will be restablished.
Some would however innovate, for example generating their own electricity, or finding ways to use less, and could survive even if they not so competitive in other areas. In various countries you can see offices, factories and warehouses with solar panels on them.
Green energy wouldn’t be enough. You just can’t manufacture enough equipment and install enough equipment to make a difference. Wind energy you can only put it in certain areas. And solar energy is very expensive to produce and install.
You can, but of course not in a single year (or a few years). But in a decade you can significatively increase renewable production. China for example, between 2011 and 2021, has made x8 in wind energy production, x20 in solar and x2 in hydro. In total renewable production almost tripled, increasing the renewable percentage from 17% to 27% in a period when China almost doubled total electricity production/consumption due to its strong economic growth.
