Elaboration on the reasons why would be nice.

143

Uranium is $128.30/kg

After enrichment, conversion and fabrication that's $3400/kg for 4.95% fuel.

At 36-45MWd/kg and a net thermal efficiency of 25% or $12.5/MWh up front.

With a 90 month lead time (72 month fuel cycle and 18 months inventory) at 3% this is $16.2/MWh

Which some solar projects are now matching

What the fuck? It's called a starter home. How is the existence of sane-sized singe-family or mutli-family homes supposed to be a bad thing?

Coal consumption is quadruple now, and oil and gas are both on the same scale. Easy to turn those centuries into decades by increasing emissions 6-fold.

Blaming population is also inaccurate. The new people are largely not wealthy (both country by country and within each country) and contribute less to the totall emissions than a quarter of the upper 10%.

There's also the bit where we have at least two "universe's most special boy/girl" characters upon whom everything hinges repeatedly when the entire point kf the psycho-history concept is that major events like that happen one way or another regardless of the specific details.

This isn't an "all of the above approach" though, it's a "cancel the short term plans and pretend we're going to do something later" approach.

Mass famines and heat that kills without AC coming summer of 2024 or 2025. Won't kill the global north too much yet, but it will be one of the biggest deadly events in history for the rest of the world.

Bifaciality isn't new or limited to perovskite based PV. Ground reflection is also not the only source of indirect light.

This article is very bad, but bifacial panels are starting to dominate the industry for good reason. The backside gives a 5-20% boost in total annual yield (which is worth it on its own), but more importantly that boost is skewed towards times with low direct irradiance (such as cloudy days). This reduces the amount of storage required.

It also allows other orientations. Vertical installations have huge advantages including better compatibility with agrivoltaics, generation skewed towards times where low tilt panels don't produce (morning-evening for east-west and winter for north-south), better dual use, and lower racking cost. Glass-glass encapsulisation is also more durable and this alone pays for most of the added cost.

If the entire world turned vegan would it make a difference?

...yes. Plainly and obviously. Most land use would be gone overnight. Deforestation would stop immediately as would the second largest source of methane, one of the largest sources of NO2, and billions of tonnes of CO2 per year (about a quarter of all emissions). No other single initiative other than maybe ending urban driving would come close.

If you're in the global top 50% there is absolutely nothing stopping you from switching to a primarily plant based diet, and if you're in the bottom 50% you probably don't eat enough meat to be a major impact.

It's not a godwin if they are literally nazis performing a literal genocide whilst literally losing a war of agression in Europe.

Toyota do have a decade or so unbroken history of promising anything that will slow BEV adoption and then delivering a turd sandwich. Here's hoping it's different this time.

...and decreasing the utilisation of their coal fleet to the point where their coal consumption for electricity is flat and set to start decreasing next year.

And their renewable energy share is higher than the US (and most of the world) and increasing faster.

Stop whatabouting and fix your own shit.
