You are correct that this is not a prisoner's dilemma, it is a tragedy of the commons[0]. However, if a wizard could magically control the "personal decisions of 99% of Earth population" and make them optimal for reducing CO2 emissions then, believe me, climate change could be trivially solved.
It is a classic cooperation problem. Perhaps not prisoners dilemma. Perhaps not at individual scale. Probably tragedy of the commons.
Cooperation is not consuming fossil fuels. Defection is consuming fossil fuels.
If you cooperate and other defects you suffer climate impact and expensive energy (expensive everything, worse economic growth than others).
If you defect and other cooperates you suffer climate impact but at least you get cheap energy (cheap everything, more economic growth than others).
People, nations, corporations, etc don’t stop using fossil fuels because they incur a penalty against their competitors if they volunteer to and their competitors don’t.
The assumption here is that fossil fuels are actually cheaper. But an electric car pays back the higher upfront cost in fuel savings in significantly fewer miles than most cars will have put on them. Solar generates power at a lower cost per kWh than coal.
The fossil fuel industry has to be actively sustained through subsidies and government regulation hostile to alternatives. Maybe that wasn't true 50 years ago before the alternatives got viable and cheap, but if it's not true now then why did we stop subsidizing electric cars while we still subsidize oil companies?
WDYM personal decisions don't matter? Industrial and agricultural sectors, which both in sum contribute 50% of total greenhouse gas emissions, produce what is in demand from consumers. Another 15% of emissions is from personal vehicles. Changing personal habits is the only way we can ever reach some utopian climate targets. Utopian because old habits die hard.
Once again, personal decisions on the consumer side doesn't matter here. Unless all consumers cooperate to force a ban on practices that are bad for environment. However that basically means forcing specific decisions on the 1% that control laws and business.
If consumers stop buying gas guzzlers, the impact of personal transportation on the climate will reduce. Are you suggesting the 1% controls the minds of the 99% to do things that are harmful to the environment? Past some point, there is at least some level of personal responsibility?
Several car companies had plans to stop making ICE cars at some point in the near future. Everyone stopped buying their cars and they have had to backtrack (e.g. Porsche). We have all collectively decided that environmentalism is hot air (tee hee) and we'll just continue with business as usual.
Current bitcoin price is around 35k USD. This means that mining of one BTC going to cost you up to 35k USD (including the cost of equipment, electricity and everything else like the probability of finding a block). Why so? If the cost of production was higher than market BTC cost then it would be not profitable to mine. If cost is much lower then it's worth to buy a mining rig and start mining.
1 block gives 6.25 BTC for the block and around 0.5 BTC from transactions. 1 block contains 4k transactions.So 35k US/BTC * (6.25 BTC + 0.5 BTC) / 4k transactions ~= 59$ per transaction. That includes all energy spent by all active miners and full cost of equipment.
Not sure if a "swimming pool of water" costs 60$. I guess not.
Keep in mind that IT domain is somewhat separated from the rest of all other economics of Belarus. Pay rates in IT-related companies a much higher than in in almost any other domain. On the other side, most of heavy industry, education and medical service are in decline.
Frequency of metro trains is reduced if compared to what there was had few years ago. 2 minute intervals are only on rush hours. Most of other time it's ~7-10m intervals.
Electric buses are used only on single route in the center of the Minsk.
Yandex and Uber in Minsk are joined into single company. So you can't say that Yandex beat Uber :)
> $9 SIM with unlimited data for a month
I suspect that this is not true. AFAIK, there are no real "unlimited" plans. There always a cap on total volume of data.
Prisoner's dilemma is about situation when optimal outcome requires cooperation from all participants.
In the situation with climate change, personal decisions of 99% of Earth population do not really matter.
