Bitcoin (BTC) is often used to criticize all blockchain-based projects. This is understandable since Bitcoin was the first project to use a blockchain, is arguably the most recognizable and is the largest cryptocurrency by market cap.
In the first half of this article, I will use Bitcoin as a proxy for all blockchain-based projects because most people associate blockchain with Bitcoin. Anything environmentally positive that can be said about Bitcoin will be doubly true for the vast majority of newer blockchain-based projects since Bitcoin uses the oldest version of blockchain technology.
Blockchain energy consumption
Bitcoin has been attacked for high energy consumption. Headlines pointing out that Bitcoin’s electricity usage is comparable to a country's total consumption is a popular critique. Comparisons are useful, but they can have a deceptive framing effect. For example, the statistics most often cited in these attention-grabbing headlines are taken from the Cambridge Center for Alternative Finance (CCAF). The same organization also points out that transmission and distribution electricity losses in the United States could power the entire Bitcoin network 2.2 times. Always-on electrical devices in America consume 12.1x more energy than the Bitcoin network.
So, the Bitcoin network uses as much electricity as a small country or far less than one sliver of America’s energy budget. Is that a lot? It depends on how you look at it.
Another often used critique is that Bitcoin’s electricity consumption is growing so rapidly that Bitcoin emissions alone could push global warming above 2°C, or consume all of the world’s energy by 2020. The latter didn’t happen. Why? First, like most network-based technologies, Bitcoin is following an adoption curve defined by the theory of diffusion of innovations — an “S curve.”
