  • Probably something along the lines of “not negative or positive, but in the middle”. Basically a synonym for net zero except net zero may account for other GHGs while carbon neutral may only refer explicitly to carbon. If the process releases CO2 at some points and absorbs the same amount of CO2 elsewhere, then it would be net zero or carbon neutral. But if you release carbon that was stored for 100s of millions of years and would have continued to be stored otherwise and then just store that same amount of carbon for 1-5 years, then you aren’t really offsetting and aren’t really carbon neutral. Given none of the offset programs seem to have presented concrete evidence for long-term storage, they’re worthless in this context. I suppose you could fund short-term storage indefinitely, but how could Apple prove that they’re going to be able to fund carbon offsets for a watched purchased today in 75 years? If funding a lumber farm program that harvests trees after 15 years, I suppose you could just fund it every 15 years after an item is manufactured indefinitely? But how would a company demonstrate they’re going to continue doing that in 75 years?










  • Wind tends to be higher at night (at least here in Texas), so solar and wind are good complements. The biggest issue here is in the summer right after the sun sets, but that just means having enough battery storage for a couple hours for temps to start dropping. But wind/solar are still cheaper after including storage for that amount of time by far compared to new nuclear or new fossil fuels. Only existing facilities have a comparable per kWh cost when compared to new solar/wind + storage. Even if you quadrupled the storage, it would still be cheaper than new nuclear and comparable to existing nuclear iirc. Granted cost of storage partly depends on what storage options are viable locally for small grids.

    Is PV common at commercial scale solar?





  • Unfortunately simply using renewables alone is t enough to decentralize them. Lately Texas has been having near energy shortages and part of the problem is a few unexpected central outages at fossil fuel plants, but another is the vast majority of wind turbines are built in one sunset of the state, so if wind is low there it can (and has) cause massive decreased in available energy, far larger than a couple traditional large scale nuclear plants when other parts of the state are under fire warnings because of high wind and dry conditions. Of course this isn’t an issue with the technology itself, but rather a problem with implementation. The issue isn’t with what was built, but the lack of building more across the state (or joining one of the two larger grids to further decentralize power production over a broader area)

    Anyways, another issue with security is centralized power production make a good target for disruption. And if you have the side effect of causing a meltdown…
