#Bitcoins are utterly unsustainable – it cannot become the general payments system many hope it will. Every single (!) transaction with #bitcoins has a carbon footprint equivalent to 59,025 hours of watching Youtube. It uses the energy of an avery US household of 25 days. 8/ pic.twitter.com/hgqsqdeBED

In times of #ClimateEmergency we use the amount of energy of entire countries to power a digital currency with close to zero use value. #Bitcoins carbon footprint is already comparable to that of New Zealand, its energy use to Chile. And it is growing. This needs to stop. /1 pic.twitter.com/1MGavJMV08

Bitcoin’s trust-minimizing consensus has been enabled by its proof-of-work algorithm. The machines performing the “work” are consuming huge amounts of energy while doing so. Moreover, the energy used is primarily sourced from fossil fuels. All info here 3/ digiconomist.net/bitcoin-energy…

The carbon footprint of bitcoins is particularly high, since mining largely happens in regions where energy is produced by non-renewable resources, in particular coal. 5/ pic.twitter.com/Nm9q6Sgs6y

Using renewables to mine #bitcoin is not a solution. Not only does this crowd out other renewable users, we also need renewable energy for other uses. 6/ decrypt.co/43848/why-bitc…

If Bitcoin was a country, it would rank between Bangladesh and Chile in terms of energy consumption. 7/ pic.twitter.com/YULAq6eJ9K
