The Environmental Argument

After five days of Bitcoin’s energy story, it’s worth looking directly at the concern that drives the criticism — and being honest about where it has genuine force.

The real worry isn’t just that Bitcoin uses energy today. It’s the long-term dynamic that’s worth thinking about.

More miners join when the Bitcoin price rises. More mining means more energy consumption. There’s no natural cap on this — the system economically rewards more mining as long as the price supports it. As Bitcoin adoption grows and the price potentially rises further, energy consumption could grow significantly.

The renewable proportion argument has a similar honest caveat. Current estimates of 50-70% renewable are based on surveys and estimates, not direct measurement. It’s plausible that the real number is lower. Miners in coal-heavy grids exist. Not all cheap electricity is renewable electricity.

These are fair points and worth holding.

Where the concern becomes less compelling is in the comparisons and the function.

Gold mining, the banking system, and countless other industries we accept as necessary consume comparable or greater energy with much less scrutiny. The question isn’t whether Bitcoin uses energy — everything uses energy. The question is whether what it produces justifies the cost.

A decentralised, censorship-resistant, fixed-supply monetary network that serves hundreds of millions of people — including people in inflation-ravaged economies and under authoritarian governments — is a more serious output than most energy critics acknowledge.

The honest position: the environmental concern has genuine substance. The response is more substantial than critics acknowledge, and more uncertain than advocates claim. Neither side has a clean win here.

Tomorrow: Bitcoin and freedom — the political dimension.
