  • Four points:

    The profile of other is short spikes 5-100 hours a few times a year.

    1 year of delay is equivalent to 20 years of exclusively using fossil fuels for “other”.

    It’s not even obvious that adding nuclear reactors would reduce this because they’re so geographically and temporally inflexible. France has 63GW of nuclear capacity, <45GW of average load and 61GW of winter peak load with vast amounts of storage available via interconnect to hydro countries. They still use 5% gas on top of the rest of the “other” (which is about 10-25GW).

    5% of other from gas adds about 20g CO2e/kg per kWh to the total. Less than the margin between different uranium sources.

    Running 40% of the capacity 10% of the time puts your nuclear energy in the realm of $1-3/kWh. The list of ways of generating or storing 6% of your energy for <$1/kWh is basically endless.

    That’s about 4-8TW of capacity worldwide. 1kg of uranium is good for fuelling about 750W of reactor on a 6 year fuel cycle. Loading those reactors would require digging up all of the known and assumed-to-exist uranium immediately.

    Nuclear is an irrelevant distraction being pushed by those who know it will not work. You only have to glance at the policy history or donor base of the politicians pushing for it in Sweden, Canada, Australia, UK, Poland, etc etc or the media channels pushing it to see how obvious it is that it’s fossil fuel propaganda.

    It is obviously obviously true that it’s a non-solution. It fails on every single metric. All of the talking points about alleged advantages are the opposite of the truth without exception.







  • 1kg of lithium produces about 10kWh of storage for 15-20 years. 3-12 hours of storage is plenty for a >95% VRE grid.

    1kg of uranium produces about 750W for 6 years.

    There are about 20 million tonnes of conventional lithium economically accessible reserves (and it has only been of economic interest for a short time).

    There are about 10 million tonnes of reasonably assured accessible uranium (not reserves, stuff assumed to exist). It has had many boom/bust cycles of prospecting.

    Lithium batteries are not even being proposed as the main grid storage method.








  • Wild concept: It’s possible to offer a fair price to someone who can. You don’t need to pay $20k for one day’s labour (although you probably do need to pay about $1k for an hour for a licensed electrician to inspect and do the final hookup if you want to AC feed for winter and cloudy days). You do not need to pay $1/W or wait years for grid tie if you have a battery and size for self consumption.

    Given how thoroughly ripped off you are and how dismissive you are of the price people in civilised countries consider normal, I’ll assume you’re in the US. Signature solar sell panels for 31c/W hybrid off-grid inverters for $2k and batteries for $280/kWh. You can probably do better if you look around and don’t just listen to the door to door MLM scammers.
