At this point, mining Bitcoin requires such intensive, specific hardware that the only way for most people to get in on the crypto game is to simply purchase the coin via an exchange. But that doesn’t mean mining has slowed down. Rather, the opposite has been happening, giving environmentalists (and anyone but the most adamant cryptobros) cause for concern.
Between cooling fans, manufacturing hardware, and the outrageous, ever-rising energy costs needed to operate a bitcoin mining rig, the world’s Bitcoin network is expected to use as much as 7.67 gigawatts of power by the end of 2018, according to new research and models. That’s one two-hundredth of all the electricity used on the planet. And that’s terrible.
Let’s put that another way. According to that research, which is admittedly based on some imperfect assumptions and averages, the Bitcoin network currently uses about as much power as the entire country of Ireland (which uses 3.1 gigawatts) and is expected to grow to the same energy consumption level as Austria, which is currently at 8.2 gigawatts.
The world’s population is right around 7.6 billion people. If everyone used the same amount of energy (which they don’t but bear with me) that would put Bitcoin’s energy consumption — and toll on the environment — at the same level as that of 38 million people.
Now, this certainly doesn’t mean that bitcoin should be cancelled. And while it seems like nothing can convince crypto fans that bitcoin is anything but the way of the future, these findings show just how much of an impact the cryptocurrency is having on the world. And not a “we’re gonna take back the financial markets and build a better tomorrow!” kind of impact. More of a tangible “oopsy-daisy, we’re accidentally scorching the planet” kind.
If cryptocurrencies are truly going to become the money of tomorrow, then we'll absolutely need to grapple with the environmental damage caused by this major energy suck (assuming the price of Bitcoin continues to climb). Or, figure out how to mine more efficiently. Because again, in the next six months we may see Bitcoin using as much electricity as a major industrialized nation.
