Great Britain is finding out that going without coal power is a lot easier said than done.
.
.
Summer temperatures in the UK have boosted the demand for electricity, and so the country has “started burning coal again for electricity generation for the first time in a month and a half,” reports Blackout News here, citing the Telegraph, June 13, 2023.
Apparently in summer weather, Britain’s solar panels have refused to cooperate.
In the heat, their efficiency dropped considerably and so the country’s electricity demand could not be met without coal power.
.
Coal to the rescue.
.
“On Monday 12 June, a unit at the Ratcliffe-on-Soar coal-fired power station in Nottinghamshire, owned by German energy company Uniper, went back online in the UK, after a weeks-long break.
Another coal-fired power station was kept on standby, in case additional power demand arose in the early afternoon,” according to Blackout News.
“The yield of solar energy the previous weekend was almost a third less than the weekend before.
This was due to the high temperatures, which exceeded 30 degrees Celsius in many parts of the country,”

Solar’s many technical drawbacks
.
This represents yet another technical drawback solar energy faces.
It not only works extremely poorly in the wintertime, when electricity is in high demand, but also in the summer when temperatures climb in the range of 30°C.
The only time solar panels seem to work is when they are not really needed, such as around midday.
.
Solar panels are designed to work best when their surface temperature is 25″C.
But in the summertime, their surfaces can easily reach 60 or even 70°C.
According to the rule, every degree temperature over 25°C means a 0.5% loss in efficiency.
That means at 65 C, the panel loses 20% of its rated efficiency.
.
25% less output
.
“Alastair Buckley, Professor of Organic Electronics at the University of Sheffield, explained that the higher temperatures have contributed to much of the decline in solar energy production.
Compared to a cool, cloudy day, solar panels could be more than 25% less efficient,” writes Blackout News.
In Germany, where nuclear power has been foolishly phased out, the country is coping with its energy troubles in its own brilliant way: importing nuclear power from France!
Germany Signs Long-Term US LNG Deal at High Cost per million Btu to Replace Reliable Russian Pipeline Gas at Low Cost per million Btu
Germany’s state-controlled firm Securing Energy for Europe (Sefe) has signed a 20-year deal with Venture Global LNG to import 2.25 million metric tons of LNG per year from Venture Global’s third project, CP2 LNG, as Europe’s biggest economy is looking to secure gas supply after Russia was forced to stop deliveries after the US destroyed its Nordstream pipelines.
Germany plans top import 70 million metric ton of LNG by 2030
