If you had a business and someone pointed out that you had a serious carbon footprint problem, what would you do? We’re seeing this a lot lately – public outcry over things that can be easily fixed or changed without trouble that can have a major impact on our planet like disposable grocery bags in grocery stores or plastic straws in bars and restaurants. It turns out that cryptocurrency also might have a carbon footprint problem, and it looks like it’s still early enough in the game to turn the tides.

Bitcoin is the particular cryptocurrency of tree huggers’ ire at the moment. In order to be self-limiting Bitcoin limited the speed at which coins could be released to control the rate at which the value fluctuates. They do this by making algorithms more and more difficult with each release, meaning that Bitcoin miners have to use more and more energy as they compete for each coin. Current estimates have this energy use at the same level as nine U.S. homes for one day per transaction. If you’re looking to trade Bitcoin, take a look at some of the best Bitcoin robots out there.

Not all cryptocurrencies are like this, and fortunately there’s still time to remedy this situation. Bitcoin Lightning is currently under development and when launched it will seriously decrease the amount of energy it takes for each Bitcoin transaction. Other future cryptocurrencies can be built with this problem in mind, eliminating excess energy use before it becomes a problem. There are also opportunities to tap into renewable resources, as is currently being done in China with hydroelectric power. There’s even a company that bought all the land around the Tesla gigafactory, signaling that solar energy could be the next big thing in cryptocurrency.

Businesses must consider their carbon footprint in order to remain competitive in the eco-concerned 21st century. Learn more about cryptocurrency’s carbon footprint problem and what can be done about it from this infographic.
