However, there are also more critical voices towards this survey, which see the proportion of sustainable sources as being significantly lower. For example, the Cambridge Bitcoin Electricity Consumption Index (CBECI). For a long time, he saw the proportion of sustainable sources in Bitcoin mining to be only 40 percent. Recently, however, the team at Cambridge University revised their approach to provide a more precise representation of Bitcoin’s energy consumption. It was concluded that the energy consumption of the Bitcoin network in recent years was actually significantly lower than previously assumed. Data from the Bitcoin Mining Council seems to confirm this development: According to this, the share of sustainable energy in Bitcoin mining has been growing for years, which the data for the fourth quarter of 2022 seems to confirm. Here too, it is worth putting the data in perspective. Because: Most recently, Bitcoin mining used significantly more renewable energy than Germany, the EU or the USA. In Germany, for example, the share of renewable energies in the overall mix is currently only 48.8 percent.
