    Last week on Wed 8th July there was a nasty power price spike in Victoria for an hour in the evening, averaging about %7/kwh for half an hour. The main cause: shortage of coal at Loy Lang coal fired power stations. Coal is unreliable. This was the first real price spike in Victoria in the 10 months since I joined Amber in September 2025.

    RE: https://climatejustice.social/@ketan/116575438387533704 Electrifying the trucks and heavy machinery that use most of Australia’s diesel would be a sensible, long term beneficial action to help adapt to fossil fuel supply issues and global warming. It would also strengthen our economy. Fortescue Mining is doing it. Why doesn&amp;#39;t the federal govt encourage it?

    We went for a short walk about 9pm last night &amp;amp; saw some small bats catching insects over the houses ... in Brunswick- inner Melbourne. The first time I&amp;#39;ve seen/been shown them. I&amp;#39;ve seen fruit bats by the hundred here, but these little ones (blackbird size?) Were new to me.

    @tobeB Surely It&#39;s better for oil to be turned into plastics &amp; eventually buried than for it to be burned for transport or energy? It&#39;s useful to have an alternative market for oil &amp; gas that doesn’t just burn it, to avoid price drops leading to continued burning, although eventually that market will support new oil/gas fields. Burning plastics for energy does not help: It&#39;s higher CO2 per kWh than oil as well as emitting toxins.
