In recent years it has been well\ndocumented that Bitcoin mining requires a large amount of energy<\/a>.\nWhile Bitcoin mining\u2019s ever increasing energy consumption has been a topic of discussion\nfor some time now, recent reports have highlighted that Bitcoin mining\u2019s energy\nusage is continuing to grow at a staggering rate. <\/p>\n\n\n

For some perspective, in May 2018,\nit was estimated that Bitcoin mining was consuming about 2.6 gigawatts of\nelectricity per day, it has now risen to over 5 GW of electricity per day and\ncould potentially rise to 7.7\nGW of electricity<\/a> per day by the end of the year. In fact, Bitcoin\nmining now accounts for about 1\n% of the world\u2019s total electricity consumption<\/a> and now takes as much\nenergy as mining for gold.<\/a>\n<\/p>\n\n\n

Bitcoin\nmining\u2019s immense and growing total energy consumption have caused Bitcoin\nminers to search throughout the world for a cheap source of electricity in\nplaces such as the State of Washington,\nChina, and Iceland.<\/a> This search and utilization of cheap electricity\nby miners present difficult and unique challenges for local residents and\nutilities in Bitcoin mining localities. <\/p>\n\n\n

Understanding the issues\nsurrounding Bitcoin mining and energy consumption requires a working\nunderstanding of Bitcoin, how its mined, and what makes mining such an energy\nintensive process. Bitcoin is an open source\nsoftware<\/a> that is a decentralized cryptocurrency, which allows users,\nvia a peer to peer network, to transfer Bitcoins. Transfers are tracked on what\nis essentially a giant ledger called the blockchain<\/a>.\nSince there is no central authority to verify transactions, volunteers referred\nto as miners, set about verifying the transactions. Each time miners verify a\nblock of transactions it is added to the ledger and the miners are rewarded\nwith a few Bitcoins. The verification process requires an energy intensive computing\nprogram that solves an immense and complex mathematical\nproblem<\/a>. <\/p>\n\n\n

Nowhere has miners hunt for cheap electricity\nhighlighted the challenges faced by local residents and utilities than in the\nMid-Columbia Basin (\u201cBasin\u201d) in Washington. The region attracted the attention\nof miners due to its vast excess of hydro-electric power, electricity rates one\nfifth of the national average, and cool and dry winters that lessen the equipment\ncooling demands. These factors made it one of the ideal locations to perform\nthe energy intensive calculations necessary to\nverify Bitcoin transactions.<\/a> When miners first moved in to the area,\nresidents and local utilities were unperturbed by the new business since the\nminers were only collectively using a few hundred kilowatts or a couple of megawatts\nat most. However, as large-scale commercial miners came to town this rapidly\nchanged. The Basin\u2019s utilities have now received applications for future power\ncontracts that, if all of them are approved, will take up 2000 MW or two thirds\nof the Basin\u2019s total power output, which has forced the Basin to confront the\ncosts and benefits faced by other mining communities throughout\nthe world.<\/a> <\/p>\n\n\n

Locals in Bitcoin mining communities recognize and value that the new business is bringing both investment and a new high-tech industry to their area.<\/a> However, they are not without concern. \u00a0First, many locals and industry commentators are worried that this is similar to the dot-com bust.<\/a> Mining Bitcoin only makes sense if the costs of mining it are less than the reward one receives for verifying a block. In order to keep the supply of Bitcoin under control, over time the Bitcoin operating system not only makes the calculation to verify a block of transactions harder, but it also decreases the number of Bitcoins rewarded for successfully verifying a block.<\/a> Therefore, there is a possibility that in the near future it will not make economic sense to mine Bitcoin for most miners. This leaves utilities and localities in a situation where they have invested a lot in providing a large amount of power to a location, that may not need it in a few years. Second, in many of the areas that have become mining hubs, such as the Basin, excess power was one of the areas greatest resources.<\/a> Local residents and utilities are hesitant about losing this resource. Third, utilizing such a large amount of power requires that miners take safety precautions<\/a> to prevent electrical overloads and fires. There is at least some evidence, such as a fire in a converted laundromat in the Basin<\/a>, that these precautions are not being properly implemented. The future of Bitcoin mining is uncertain, but there is no doubt that it is here to stay in at least one form or another. Utilities are required by law to consider any legitimate request for power<\/a> and miners should have the right to consume power for which they are paying the going rate. Furthermore, Bitcoin mining can also bring new investment to a locality. \u00a0However, the concerns from local residents and utilities of mining hubs as well as the challenges facing the future of Bitcoin mining should not be dismissed lightly. Both sides must work together to develop an equitable solution to the challenges of Bitcoin mining. <\/p>\n\n\n
