“The challenge with rising renewables: As power systems rely more on asynchronous generation, frequency changes can occur much faster, increasing the risk of grid instability.” (- Dave Edwards_
Dave Edwards post begins: “As an engineer I like to understand how systems operate, this is useful for fault diagnosis, especially when a system fails and a Root Cause is needed, though maybe more than one contributing factor. So let’s Talk “Inertia” 🙋♂️Everyone’s Saying It, But Who Really Understands It 🤷♂️”
The floor is his:

Julia Vol last month wrote on the business social media platform LinkedIn:

“Climate hypochondriacs deserve to be treated with compassion, much like anyone who suffers from mental illness. They shouldn’t, however, expect everyone else to enable their neuroses.” – Allysia Finley, Wall Street Journal
The futile, wasteful climate crusade has created collateral damage for the cause of the Progressive Left. Their political weapon against ordinary living in a free society has run afoul of ordinary folk, consumer and taxpayer all. And with the government lucre running low or out, and the political forces aligned against them, there is fear, even panic, that their cause is hopeless and unconvincing. “Open for work,” hundreds of climate activists have circled around their names on the business site, LinkedIn.
When the climate movement was at its peak in mid-2022, the faithful knew they were winning political battles but losing the war against carbon dioxide (CO2).…
