This is very nerdy. But super interesting if you have the time.
I learned about the difference between AC (the standard grid) and DC (renewables), the difficulty of going from DC to AC, the importance of keeping the electricity going through the wires at a fixed frequency -- usually 50Hz.
And that there's the concept of "inertia" that affects how all this fits together and how it makes for the dangers of a Spanish-style blackout. Kathryn Porter explains all of this very well. To Konstantin Kisin and Francis Foster, the lads at Triggernometry.
In the UK, the cost of moving to renewables is hidden in the electricity bill. That's why they're higher than ever. But why people don't notice it quite so much, because it's not defined openly, as a tax would be.
I suspect that the same is true in Australia, which is why bills are going up, when they are supposed to be going down, according to our political masters.
This video is really worth sitting down to listen to.
Final point: renewables are NOT cheap. They're most certainly not the cheapest. So says Porter. With the receipts.
Side note: we here in Hong Kong already have the emissions per capita that Australia is struggling to reach. But we've done it by a combination I call NAG: Nuclear and Gas. Kathryn Porter says pretty much the same. But Australia says "NO" to Nuclear. Which to me calls into question the whole Net Zero project. It's not just the U.K. It's every other nuclear nation that's powering ahead with new Nuclear projects.
Shame on us.
