Solar Was the Leading Source of Electricity In the EU Last Month (www.cbc.ca) 70
In June 2025, solar power became the leading source of electricity in the EU for the first time, surpassing nuclear and wind, while coal hit a record low. CBC reports: Solar generated 22.1 percent of the EU's electricity last month, up from 18.9 percent a year earlier, as record sunshine and continued solar installations pushed output to 45.4 terawatt hours. Nuclear followed closely at 21.8 percent and wind contributed 15.8 percent of the mix. At least 13 EU countries, including Germany, Spain and the Netherlands, recorded highest-ever monthly solar generation, [data from energy think tank Ember showed on Thursday.]
Coal's share of the EU electricity mix fell to a record low of 6.1 percent in June, compared to 8.8 percent last year, with 28 percent less electricity generated than a year earlier. Germany and Poland, which together generated nearly 80 percent of the 27-country bloc's coal-fired electricity in June, also saw record monthly lows. Coal accounted for 12.4 per cent of Germany's electricity mix and 42.9 percent of Poland's. Spain, nearing a full phase-out of coal, generated just 0.6 per cent of its electricity from coal in the same period.
Wind power also set new records in May and June, rebounding after poor wind conditions resulted in a weak start to the year. But despite record solar and wind output in June, fossil fuel usage in the first half of 2025 grew 13 percent from last year, driven by a 19 percent increase in gas generation to offset weak hydro and wind output earlier in the year. Electricity demand in the EU rose 2.2 percent in the first half of the year, with five of the first six months showing year-on-year increases. The next challenge for Europe's power system is to expand battery storage and grid flexibility to reduce its reliance on fossil fuels during non-solar hours, Ember said in the report.

France didn't get most of their power from nuclear last month because fun fact, much of the nuclear capacity was shut down as it couldn't cope with the summer capacity.
Also if you need to compare solar energy with an energy source that is not just subsidised but had to have the main player nationalised due to bankruptcy I think you've lost before you even started playing. Yeah ask the French government who had to buy out its entire industry just how "cheap" it was.
And yes solar is now so cheap that it is cheaper to to build enough capacity with panels + batteries to compete with coal (not gas, gas isn't cheap in Europe) over a complete 24 hour period during the summer.
UK cost per kilowatt hr is $0.35USD. French cost per kilowatt of power is $0.26USD.
None of these prices have anything to do with cost of production. The overwhelming majority of a retail bill (or even wholesale bill) is made up of taxes, transmission fees, and connection fees. The actual cost of nuclear power in France is between $0.06 - $0.10/kWh (with the most expensive being thanks to the LCO contribution by recently wildly expensive projects), vs grid scale solar is currently around $0.03/kWh
