This is a common set of misconceptions, so I'll try to explain why they're wrong. The people of India and China can absolutely maintain a lifestyle with your energy consumption and use of manufactured luxury goods without causing ecological damage. 80% of electricity produced in Denmark is renewables, mostly wind. Historically, renewable energy other than hydroelectric and low-efficiency wind had a poor EROEI, so it…
Thank you for a very thorough reply. Interesting read. We very obviously read different things. Basically what I hear you saying is: we have the technology, we can do it. Please correct me if im reading you wrong. And sure, that is the hope, and I'm not saying that we wont be able to find solutions - simply that our current solutions wouldnt work if scaled to the world. My argument is simply that we're on a massive e…
I think the case of refrigerators is particularly interesting. Other than energy, they don't consume limited resources; they just contain limited resources until they're thrown away. Some of those resources are scarce, like copper, aluminum, and the refrigerant itself, and because it's profitable, those tend to get recycled already, even without government mandates (though sometimes government mandates can prevent it, like the "steps to stop illegal trade in HFCs" mentioned in the article you link). Others are not scarce, like iron, fiberglass, and polyurethane, so it isn't a problem if they are locked up in a landfill. At some point mining landfills will be profitable when the mineral resources they contain are depleted in their original mine deposits.
The problem of leaks of fluorinated refrigerant is real, but https://en.wikipedia.org/wiki/Climate_change#Greenhouse_gase... says that total fluorinated gas (including refrigerants from air conditioners and refrigerators, propellants, sulfur hexafluoride, and others) is only about 3% of the total greenhouse forcing, and https://en.wikipedia.org/wiki/Greenhouse_gas_emissions#/medi... gives 2.1%. Plausibly this is the largest climatic effect of buying a refrigerator, even if it's manufactured with 100% coal energy, but in absolute terms it's not that significant. And I don't think the number of refrigerators is going to more than double; according to https://globaldatalab.org/areadata/fridge/?levels=1%2B2%2B3%... even in Bangladesh 40% of households have one, and 35% in India and 99.9% in China; and https://bigee.net/media/filer_public/2012/12/04/bigee_doc_2_... gives the number as 1.4 billion domestic refrigerators ten years ago. So we might see that 3% grow to 5% or something, but not a high enough level to make a real difference. I don't think it's accurate to describe 3%, or even the 10% in the article, as "a huge part in global warming".
I used to have a refrigerator that didn't use greenhouse-gas refrigerants. It was an ammonia-absorption refrigerator, using ammonia, water, and hydrogen. These are unfortunately not available in my country (illegal, I think), and it is not safe to have them inside a house, but it's perfectly reasonable to keep them out on the patio. One big plus is that they can run on stored fuel, whether natural or synthetic, which would be really nice with the frequent power outages where I live now.
Sort of by coincidence, I've been trying to figure out this month how far desiccant-enhanced evaporative cooling can replace conventional vapor-compression air conditioning. I think I've found ways to reduce the system cost low enough that multistage cascades are economical, which ought to make it possible to do not only air conditioning but even domestic food refrigeration with desiccants, though freezing will require a different approach. I found some really interesting research from NREL on this, mostly over the last decade. Desiccant-based systems have the potential to provide not only cooling but also humidity control, heating, food preservation, and household solid waste treatment, and they can run on stored energy for days, which is important both during power outages and to ameliorate the intermittency of solar and wind energy.
