Tech Desk: Bitcoin miners energy consumption around the world is more than over 150 countries

The global electricity consumption used for bitcoin ‘mining’ has reached a level that there are over 150 countries which consume less electricity in a year. In other words, if bitcoin was a country, at current value, it would stand at 62nd position in the world in terms of consuming electricity in a year.

As of November 22, the ‘miners’ have consumed 29.51 TWh (1 TWh= 100 crore units) of electricity, according to the Bitcoin Energy Consumption Index by Digiconomist. And, if the consumption keeps growing at the same rate, by the end of the year, it would stand at 38.36 TWh of electricity, placing it at 58th position, just below Hungary, in terms of total electricity consumption. In fact, the total energy consumption is more than that of Ireland which uses 23.79 TWh of electricity and North Korea at 11.24 TWh.

Similarly, mining ether or etherum — the next most valued cryptocurrency, has consumed 10.41 TWh of electricity as on Wednesday. That is almost the equal amount of electricity Paraguay consumes in a year.

What is bitcoin mining?

Mining bitcoin is a hardware intensive process which requires the computer or a user to solve a mathematical problem. Once a solution is reached, a transaction is validated and resultantly a new block is created in the blockchain which contains the information related to that transaction. As a reward for validating the transaction, a ‘miner’ earns a new set of bitcoins.
However, by design, not every solution will lead to a block creation. It is more like a lottery, where there will be several hits and misses. Hence, logically, the probability of success increases if the number of attempts is greater. This is what drives miners to try more and which again results in greater consumption of electricity.

The Digiconomist Index to compute the amount of electricity consumed assumes that a miner spends 60 percent of its bitcoin income on electricity. According to the website, “the assumption has been chosen in such a way that it can be considered to be both intuitive and conservative, based on information on actual mining operations.”

The growth in consumption and projection
In the last one month, as per the estimate, the consumption has grown by 30 percent which is indicative of surging interest in the currency. Comparatively, in the same time frame, the value of bitcoin has soared over 40 percent.
At present, the consumption is 0.13 percent of the global electricity consumption. Assuming that the countries don’t add any new power generation capacity and the growth in the consumption due to mining remains the same, bitcoin mining would consume as much electricity as India consumes every year (1,126.5 TWh) by January 2019. And, by January 2020 (at a monthly 30 percent growth) it will surpass the total consumption of the world as of now (22,383 TWh).
