Bitcoin Energy Consumption: How Green It Really Is


Bitcoin is decentralized and hence it’s controlled and maintained by thousands of computers in the public network, Blockchain, which consumes a lot of power. Again, Bitcoin miners need to verify new transactions, which requires high computing power. It’s one of the key reasons for high energy consumption.

In this article, you will know about the energy consumption due to Bitcoin and how green it really is—interested in Bitcoin trading? visit bitpremium.

Bitcoin Energy Consumption

Bitcoin being the most valuable digital asset, many people want to do Bitcoin mining. However, the primary concern is the need for low-cost energy supply. Since mining of Bitcoin requires high computing power, the devices used for mining consume a large amount of energy.

That’s why many environmentalists raise voice against Bitcoin. They claim that Bitcoin mining is a threat to the environment. Since mining organizations that are dependent on low-cost energy sources such as coal-fired power plants are dangerous for the environment, these power plants produce large amounts of toxic emissions.

Why Does Bitcoin Need More Electricity?

Although Bitcoin works purely in a digital platform, the computers which run this digital currency are consuming a lot of energy. According to a report by Digiconomist, the annual energy consumption due to Bitcoin is around 66.7 terawatt-hours.

The large electricity requirement of Bitcoin is rooted in its foundations. All the transactions are stored in a public ledger, and new transactions need to be verified before they are added to the record. Bitcoin miners verify these transactions for which they get rewards in Bitcoin, so mining is becoming increasingly competitive.

Since mining requires high computing power, it’s the main cause of high energy consumption. Moreover, some miners want to cut their expenses to increase their mining profits. So, they choose low-cost energy sources that are producing harmful emissions.

Bitcoin Miners Need Low-Cost Energy Provision

Why do mining companies need a low-cost energy supply? It’s quite simple; they want to gain profits from mining. So, they need a low-cost energy supply, which will reduce their expenses in mining. Since more than 60 percent of the mining revenue goes into electricity, it’s hard for miners to make profits from mining where energy cost is high.

So, some crypto mining companies choose the cheaper way, which is not environmentally friendly. However, using efficient mining hardware like ASIC or GPU and sustainable energy sources is the best way to remain in the Bitcoin mining network.

Which Are The Best Energy Sources for Bitcoin Mining?

For a green energy source, Bitcoin needs to adopt energy sources that are relatively cheaper but should be environment friendly. Some of the best sustainable and low-cost energy sources are:

  • Wind Energy: Wind energy sources have many potential benefits, such as cost-effective, clean fuel-source, and sustainable. However, it’s not suitable for everyone since wind sites are mainly located in remote places. So, it’s not an advantage for the people who are living in cities.
  • Solar Energy: It’s also a great sustainable energy source for Bitcoin mining. It’s a clean energy source, and there is very low-maintenance cost as there are literally no moving parts. However, it’s weather dependent, and people living in cold areas may not get the benefits of this energy source.
  • Hydro Power: It’s also a great clean energy source as it does not produce harmful emissions like coal or fuel-based power plants.

Bitcoin mining companies that run in these power sources don’t have any negative impact on the environment. However, what is the number of mining companies that are dependent on these energy sources?

Is Bitcoin Truly Green?

Recent studies have shown that more than 50% of the Bitcoin mining network are running under renewable energy sources. In some places like Canada, some mining companies are totally run on renewable energy. Many power companies are also planning to provide special energy sources for crypto mining operations. This can make the Bitcoin mining process green and cost-effective.


With the facts presented above, approximately 50-70% of mining networks are running in sustainable energy sources. So, we expect that Bitcoin will run completely on clean energy sources.
