The great Bitcoin energy debate

What this episode covers

Ben Hertz-Shargel, global head of grid edge at Wood Mackenzie, explains that Bitcoin mining currently consumes 3.9 gigawatts in the US, raising retail electricity costs in Texas by approximately $1.8 billion annually and increasing emissions by 85% through the dispatch of coal and natural gas plants. He argues that while mines are flexible, they do not incentivize new renewable generation due to credit and tenor mismatches, and their demand response participation merely offsets the harm they cause. Hertz-Shargel notes that while flared gas capture is a net benefit, the broader industry represents a significant opportunity cost for the energy transition, especially as alternatives like Ethereum's proof-of-stake exist.
