In June of last year, a 14,000-panel 5.2 MW solar panel farm called the Scottsbluff Community Solar Array in Nebraska was blasted by baseball-sized hail. There wasn’t any question that the array would be brought back online because the power company had no choice. Leaving it would have been a PR disaster worse than having the array destroyed by hail.
It took 7 months to bring it back online. //
Solar releases a nasty thing called nitrogen trifluoride. And, what, pray tell is NF3’s impact on the environment? It is reportedly 17,000 times worse for the atmosphere than the dreaded CO2.
And there are other inconvenient facts like 80 percent of the silicon torn from the earth during the mining is eventually lost making crystalline silicon. A cancer biologist named David H. Nguyen noted that toxic chemicals associated with solar farms include cadmium telluride, cadmium gallium, copper indium selenide, and a bunch of other nasty toxins. Sometimes you have to wreck the environment to save it.
Solar acolytes will grudgingly admit that there is a chemical downside to manufacturing solar panels – like a byproduct called silicon tetrachloride. It’s toxic and, if not handled properly, will cause severe burns. If it is inadvertently combined with water it can create hydrochloric acid. But hey, they are made in China so, never mind. //
Northeast of Edward Air Force Base sits the tiny town of Boron. The surrounding desert is home to desert wildlife including the Joshua tree. It will soon be home to a vast solar farm owned by Aratina Solar Center. Joshua trees can survive 200 years in the desert heat but they won’t survive in Aratina’s heat sink of a project.
About 3,500 Joshua trees will be uprooted and destroyed to make room for the solar farm. Aratina (owned mostly by a private equity group known as KKR). To mitigate the bad press, Aratina is shredding trees on-site rather than piling them like so many corpses. //
On completion, the project will blacken about 2,300 acres but it will generate power for up to 180,000 homes. //
Sometimes you gotta kill a tree, to save a tree.
This graph shows the number of sunspots seen each year for 400 years (from 1600 to 2000). There were almost no sunspots during the Maunder Minimum. During the Dalton Minimum, there were fewer sunspots than normal. //
The first written record of sunspots was made by Chinese astronomers around 800 B.C. Court astrologers in ancient China and Korea, who believed sunspots foretold important events, kept records off and on of sunspots for hundred of years. An English monk named John of Worcester made the first drawing of sunspots in December 1128. //
It would appear that sunspots not only have a connection to geomagnetic activity at Earth, but they play a role in climate change as well. In the last thousands of years, there have been many periods where there were not many sunspots found on the Sun. The most famous is a period from about 1645 to 1715, called the Maunder Minimum. This period corresponds to the middle of a series of exceptionally cold winters throughout Europe known as the Little Ice Age. Scientists still debate whether decreased solar activity helped cause the Little Ice Age, or if the cold snap happen to occur around the same time as the Maunder Minimum. In contrast, a period called the Medieval Maximum, which lasted from 1100 to 1250, apparently had higher levels of sunspots and associated solar activity. This time coincides (at least partially) with a period of warmer climates on Earth called the Medieval Warm Period. Sunspot counts have been higher than usual since around 1900, which has led some scientists to call the time we are in now the Modern Maximum.

California: Climate Groups Push to Stop Re-Licensing of Diablo Canyon Nuclear Power Plant – RedState

I hope the loons win. Because CA deserves it.
On the other hand, maybe Diablo can claim it identifies as a solar plant and ask CA politicians to pay for energy reassignment surgery?
Caedite eos. Novit enim Dominus qui sunt eius.
The forecast for California’s solar power expansion is cloudy, with a good chance of pain.
