In a recent Skeptics Newsletter, I was a bit miffed about what I see as a lack of scepticism around the so-called 'energy transition'. Patrick highlighted a blog projecting that global investment in renewables would soon be more than spent on fossil fuels. And then there was the link to rewiring Aotearoa. I think it's important for us to be a bit skeptical about this so-called energy transition - which isn't happening, despite all the hype. There has indeed been addition of renewable energy, but no transition because we keep using more energy (from 2021 to 2024 fossil fuel additions still outstripped renewables 2.6:1).

It's always good when we get feedback to this newsletter, and it doesn't even have to be positive! Unlike many groups, we're the kind of organisation that relishes constructive criticism and correction - and so this week's first three articles are great to have received. Firstly Mike Joy has taken the time to expand on the concerns he had about an area of climate change and fossil fuel dependence that he thought we haven't covered very well in the past. Patrick Medlicott has responded to Mike's concerns, agreeing with him that renewable energy sources aren't currently replacing fossil fuels - they're just being added on top of fossil fuel use. On a tangentially related topic, Tyler has written about Katrina's treatment of microplastics, arguing that although we don't yet know if microplastics are a problem, it may be prudent to treat them as if they are.

It appears to be common knowledge that the petrol with a higher octane rating means more power and better fuel economy. The purpose of this short article is to explain why this is a myth, and why both fuels will work as well in a car designed to run a particular fuel. So, spending extra money on premium fuels when your car's owners manual says 91 is suitable, will not give you better economy or more power.

In depressing (but expected) news this week, it seems that it's highly unlikely we'll be able to constrain global warming to 1.5C, and that we're on a path of irreversible damage to the climate which may well lead to catastrophic failure of the climate and likely extinction of vast numbers of species including humanity. It may not happen in my lifetime, but I do worry for the future young people today.

A friend sent me a video the other day about a fuel saving device for your car. The video was quite well done, and like so many videos on FB had no voice over - instead having a soundtrack, along with large subtitles telling the story:

Readers of the NZ Skeptic may find this a bit hard to believe, but New Zealanders seem to be a fairly sceptical bunch overall (Sunday Star-Times, 11 September).

I have just visited another universe; it seems a much more interesting place than the dull old world we are forced to inhabit.

It may interest skeptics to know that I have solved the world's energy problems. The concept is surprisingly simple... but then works of great brilliance often are.
