The Crypto vs Climate Showdown

In the great debate over crypto mining vs. climate, there are two camps.

First, the crypto enthusiasts, like Square, say things like, "Bitcoin is key to an abundant, clean energy future".

And then there are the energy wonks, who point out that, if bitcoin mining were a country, it would already be in the top 30 for total energy consumption, rivaling Ukraine.

The energy camp tends to dismiss the crypto enthusiasts’ thinking. They’re skeptical of how crypto mines could be assets to a decarbonizing grid, rather than a strain on it.

So to cut through the noise, Shayle spoke to Nick Grossman, a partner at the respected venture capital firm Union Square Ventures. USV was the largest early investor in Coinbase, which currently has a $49B market capitalization. But USV has gone big on climate tech and raised a specific climate fund. Nick straddles both the crypto and climate worlds, so he's the perfect person to help me make some sense out of this madness.

Nick and Shayle break down the basics of crypto currencies as energy-backed assets. They examine the argument that crypto mines improve the economics of renewables, because they will always be willing to buy cheap renewable power. This, in turn, helps to finance the overbuilding of renewable projects to help meet peak demand, or so the thinking goes.

But do intermittent renewables improve the economics of crypto mines? In other words: Is it profitable to mine intermittently?

They also discuss green bitcoin certificates and alternatives to the energy-intensive proof-of-work crypto security model: proof of stake, proof of space-time, and proof of location

And they evaluate Shayle’s (surely serious) startup pitch to match crypto mines with seasonal renewables: put the mines on barges and shuttle them back and forth between renewable projects in the northern and southern hemispheres.

Handing back the mic: Six months of data center reality, from Bragawatts to behind-the-meter, and the questions still open

A year ago the data centre conversation was about scale. Increasingly it is about what happens when the announcements meet the physical grid. New capacity is being announced at roughly 435 megawatts a...

The grid's missing operating system: Why a $100,000 AI controller could defer trillions in hardware and why utilities won't buy it

The energy transition conversation focuses on what connects to the grid. Far less attention goes to whether anyone is coordinating what those assets do once connected. AI training runs swing hundreds ...
