The validity of calculating the energy cost per bitcoin transaction has, however, been criticized as having little relevance without further context. Cambridge University's Center for Alternative Finance, for instance, pointed out that "transaction throughput is independent of the network’s electricity consumption. Adding more mining equipment and thus increasing electricity consumption will have no impact on the number of processed transactions." Digiconomist's name was also put to a 2017 prediction that Bitcoin would match the entire world's entire power consumption by 2020, an estimate which fell into a similar trap of predictions from the early 1990s about internet traffic and electricity use.
