Bitcoin’s biggest problem is perhaps not even its massive energy consumption, but the fact most mining facilties in Bitcoin’s network are located in regions (primarily in China) that rely heavily on coal-based power (either directly or for the purpose of load balancing).
Assuming that 70% of Bitcoin mining is taking place in China, and that 30% of mining is completely clean, this yields a weighted average carbon intensity of 490 gCO2eq/kWh. This number can subsequently be applied to a power consumption estimate of the Bitcoin network to determine its carbon footprint.
2019) properly account for these regional differences (while also introducing a new method to localize miners based on IP-addresses), but still find a weighted average carbon intensity of 480-500 gCO2eq per kWh for the entire Bitcoin network (in line with previous and more rough estimations).
Hudson Yards is now officially New York City's most expensive neighborhood.
A recent report by real-estate agency PropertyShark shows that in Q3, the median sales price in Hudson Yards hit $4.94 million.
