I was looking for a good explanation of 'curtailment' (paying renewable generators to turn off and gas turbines to turn on because supply and demand rarely match geographically) and this piece about the issues driving what seems like crazy behaviour is great on the historical background

Some people complain there’s too much polling in this life, but what is voting intention in the after life? Reform leads among both those who think they’d go to heaven & those who think they’d go to hell. Though their lead grows from 6 to 20 among (self selected) denizens of hell

The costs of the UK’s Global Talent Visa looks a trifle high in comparison to competitor countries - largely through the Immigration Health Surcharge (which critics say is a form of double taxation as they contribute to the NHS through normal tax on their earnings)

Zelenskyy says Ukraine will nominate Trump for the Nobel Peace Prize, if he delivers Tomahawk missiles and helps secure a ceasefire. The missiles, with 1,500 km range, would let Ukraine hit deep into Russia. Trump says he’s “sort of” decided, but wants clarity on how they'd be used.
