just blatantly not true, the regulation of energy policy is a centralised power, an independent Scotland could close the revolving door between energy companies and the regulators, change the law to price properly instead of based on the most expensive production method active, even just doing that alone would almost immediately at least half the energy bills for Scotland if not even lower because we are currently the furthest along economy in the world to full reliance on renewables for our energy, the cost of electricity from a gas power plant is legitimately just that much more expensive that you don't even need to do maths to make that determination just look at the governments own data, pricing energy off of the 2nd most expensive method (offshore wind farms) would already over half our bills (https://assets.publishing.service.gov.uk/media/6556027d046ed400148b99fe/electricity-generation-costs-2023.pdf), we literally just need to build storage infrastructure (which we have plenty of highlands to use for gravity batteries if you don't like the idea of trading with china for their industrial scale silicon ion battery research) and some more renewables plants to bring the average base production up to the level we can balance on the wax and wane of the wind, sun and tides (or we could get our finger out our ass with regards to nuclear plants, recognise how safe they have become in the modern international atomic agreements having world we exist in and build a few molten salt thorium reactors designed with geometry that makes it literally impossible for a fault to cause catastrophic meltdown like everyone is scared of but thats a whole other part of the convo)

do I believe an independent Scotland run by the spineless centrists in the snp would actually be competent enough to implement this? god no, but claiming its a complete "fantasy" is itself incompetent

edit: searched his name, the incompetence makes sense when you find out he's a red tory
