Re: Technical marvel, but it's the economics, stupid
You are looking at consumer cost, which is hard to compare and doesn't say much about production cost. Some countries have amazing grids, some country's grids are held together by tie wraps and duct tape. Some countries add extra levies to pay for grid upgrades, some don't. Some countries add extra levies for an energy transition, some don't. Some countries have a well functioning utilities market, some don't.
If you want to look at the wholesale cost per source you'd need to look at what's called the 'Levelized cost of electricity' (LCOE). Then you'll typically see, from cheapest to more expensive, something along the lines of Large-scale solar -> offshore wind -> onshore wind -> combined cycle gas turbine (CCGT) -> geothermal -> nuclear -> small scale solar * -> coal (hard) -> coal (soft) -> more obscure sources such as old fashioned gas plants, oil, etc.
Occasionally offshore wind and onshore wind trade places in that order, dependent on geography. Spain will probably have cheaper onshore than offshore wind whereas Denmark will have it the other way around. Also, load factors vary per country so some countries will have wind farms that produce about 60% of the time, other countries only 30% (often, but not solely, based on whether they have more offshore wind parks as offshore has a higher LF). But interestingly enough, even an abundance of coal in a country doesn't reduce the wholesale price that much. And neither does having serious economies of scale in nuclear, like the French have.
The thing is that the fuel cost only plays a part role in the total cost of producing a MWh. Obviously fuel cost for wind and solar plants is zero per MWh whereas gas or uranium or coal cost money but the total cost of construction, operation, maintenance, decommissioning etc. is where the real expenditure lies.
* Small scale solar, such as people putting a few solar panels on their house, is not very cheap in the grand scheme of things but because it's individuals who become less dependent on their energy supplier it might still make economic sense for them. Even more so because most other forms of electricity production are usually beyond the reach of individuals.
