The University of Cambridge has conducted an extensive survey called the “3rd Global Cryptoasset Benchmarking Study“, which provides many new facts about the world of cryptocurrencies. One of the most interesting findings is the fact that on average 39% of POW miners using renewable energy.
According to the graph, we can even see that up to 76% use renewable energy as part of their mix.
