Bitcoin Sustainability Report January 2019

After a continuous drop in Bitcoin’s energy consumption for several months, January sadly put an end to this trend. The highlights of the past month are as follows:

  • Mining revenues dropped just one percent.
  • Mining revenue from transaction fees decreased by 15 percent.
  • The total network power consumption increased by almost 4 percent.
  • The average fee per single transaction was $0.25.
  • The average energy consumption per transaction was down by around 7 percent, and amounts to 438 KWh per unique transaction (enough to power 1 U.S. household for almost 15 days).

Year to Date Performance

Apart from the changes in monthly performance, numbers on the current year to date (YTD) performance are found in the following table. These numbers show that Bitcoin has so far consumed as much energy a country like Singapore in 2019. Moreover, when comparing to the previous year, we find that Bitcoin consumed 12% more energy in January 2019 than in January 2018. Mining revenues are, however, substantially lower than at the start of the previous year.

Digiconomist is committed to promoting (the development of) sustainable blockchain technology. Blockchain protocols such as Bitcoin currently run on the energy-slurping proof-of-work algorithm (creating these proofs of work is better known as “mining”). The Bitcoin Energy Consumption index is a key tool that was created to provide insight into this energy consumption amount, and raise awareness on the unsustainability of the proof-of-work algorithm. The sustainability report uses historical data from the Bitcoin Energy Consumption Index to summarize the sustainability progress and performance of the Bitcoin protocol over the past month.
