About this episode
Depending on who you talk to, Bitcoin mines are either great for the grid or the worst thing that’s ever happened to it. These warehouses of computers essentially turn electricity into bitcoins. Proponents argue that mines can do a number of things for the grid, like: Support grid reliability by reducing demand during peak hours Incentivize new renewable generation by raising the prices that solar and wind farms receive Reduce methane emissions by capturing flare gas from fossil fuel wells and then using that gas to generate electricity for mine operations Meanwhile, opponents argue that the mines raise emissions and electricity prices. So how do we make sense of the great Bitcoin energy debate? In this episode, Shayle talks to Ben Hertz-Shargel , global head of grid edge at Wood Mackenzie. The New York Times recently reported on the role of Bitcoin mining on the grid , and Ben was part of a team that contributed to the report. Shayle and Ben discuss: How Bitcoin mines affect electricity prices for nearby consumers Whether mines use only excess renewable generation or incentivize fossil-fuel generators to ramp up What mines’ load profiles say about their flexibility and price-sensitivity, especially during peak demand The evidence on whether mines are signing long-term power purchase agreements, repowering mothballed projects or otherwise helping to incentivize new renewables construction Alternative crypto currencies that don’t require so much electricity Recommended Resources: NYT : The Real-World Costs of the Digital Race for Bitcoin Earth Justice and The Sierra Club: The Energy Bomb: How Proof-of-Work Cryptocurrency Mining Worsens the Climate Crisis and Harms Communities Now Coinspeaker : Texas Senate Passes Bill to Limit Incentives for Crypto Miners Participating in Demand Response Programs Catalyst is a co-production of Post Script Media and Canary Media .
