@wonka i am not from the US, nor have i ever been. I'm not saying PV panels are becoming uneconomical in less than 15 years. I'm saying in order for them to be sustainable, we have to ensure they're regulated to KEEP them being sustainable, so we don't end up with them being made cheaply at the cost of sustainability. as with most things.
@necrophcodr I have not yet heard of PV panels becoming uneconomical in less than 15 years here in EU (other than by external damage). If that's an actual problem in the US, and not FUD again, you USians need to have a pointed discussion with your vendors.
@wonka or to put it another way: solar panels only sound like a good idea if they can last 15+ years. if you have to replace them every other year due to low quality materials and planned obsolescence, then we might not be better off. there's a bigger picture that matters too, and it all needs to fit decently together to ensure we can ie. reduce CO2 emissions and also maintain a sustainable consumption.
@wonka no, it shouldn't stop us going towards using those, but we should absolutely be mindful of the effects those have as well. long lasting and low polluting systems may well lead to lower consumption and thus an increase in sustainability, but this is not guaranteed without being mindful and enforcing regulations that make it so.
@necrophcodr We cannot stop exhaling CO2, of course. Maybe other things. But we need to stop every CO2 emission we possibly can, and using heat pumps instead of burning stuff is a rather easy thing to do.
And that "PV needs mining and rare earth metals" thing - that's exaggeration and FUD of those who want us to continue burning stuff we buy from them.
@wonka there's a level of sustainably that may be possible, but if we are to stop entirely then the human race has to cease existing. but i do agree that current levels of consumption and industrial waste pose a great threat.
@necrophcodr If we continue exhausting CO2, earth will definitely become too hot to sustain human life. So we need to stop that and find anything else, including reducing our standard of living - or be cooked.
@wonka unfortunately to my knowledge this is impossible following current living standards. solar is not free renewable on a long enough timescale either, nor is nuclear. they're the better option I'd argue, but we shouldn't ignore their demand for destructive industrial mining and imports of rare earth metals and such, all so we can post hot takes on social medias like these.
@davep you also can't afford a nuclear power station or a wind turbine farm but you can power your house with wood burning stoves too. sure is some bias here, even if intentions may seem decent.
