Many people it seems are unable to take pride in their own heritage without being predjudiced against others, without realising they are at least part of us, and us part of them.

I wouldn't argue but I think you could probably extend that to a general lack of appreciation of/interest in any genuine expertise in the political world, be it trade, energy etc.

Two stories published Friday reporting that Trump admin had ordered US Cyber Command and CISA to "stand down" on their work to detect/counter Russian cyber threats. But new info has come out to contradict them. I dug into what we know and don't know. www.zetter-zeroday.com/did-trump-ad...

I thought this was interesting from Hannah Ritchie. Perhaps market reform (which I know UK gov is considering) is required alongside transition. Higher renewable generation may not, by itself, guarantee lower prices for industry or consumer. 🤔🤔

Do US states with more renewable energy have more expensive electricity?
Despite California being the poster child of high prices, the data suggests no.

My fave - burying cables. The length of buried cables is greatly limited at AC transmission voltages due to a phenomemon called charging current. Tens of km rather than 100km+. In addition to the expense, physics prevents it. Clearly they don't have a clue and haven't spoken to anybody who does.
