The Startling Energy Costs of Bitcoin

As Bitcoin gains credibility, power consumption worries grow

Most people are aware of the rising price of Bitcoin. Despite the fact that most people are unaware of how to transact in it, and few merchants take it as a form of currency, Bitcoin is becoming an increasingly popular investment. As interest in Bitcoin grows, a few people are starting to take notice of the startling energy costs associated with Bitcoin transactions. As Mind Matters has been pointing out for years, the energy costs associated with having a “trustless” system such as Bitcoin is immense, with Bitcoin transactions generally costing 400,000 times as much energy as a single transaction on the Visa network. According to the BBC, the Bitcoin network – which, again, very few people are regularly transacting in – now consumes more energy than the…

Could Carbon Computing Make Computers More Environment Friendly?

As a key component of life forms, carbon is abundant and energy efficient

Carbon, a very abundant chemical element, is one of the building blocks of life, partly on account of its stability. It is a minimalist element, compared to the silicon used in computing today: … carbon dioxide is is a small gaseous molecule consisting of two oxygens both forming a double bond with a single carbon while silicon dioxide is a massive behemoth of a molecule made of huge numbers of alternating oxygen and silicon atoms and is more commonly known as sand. S. E. Gould, “Shine on you crazy diamond: why humans are carbon-based lifeforms” at Scientific American (November 11, 2012) But there’s something else about carbon. As George Gilder puts it, carbon-based life forms, like humans, consume very little…
