With not enough attention in the environmental sustainability debate given to the electrical energy required by computers it is good to think that another advantage of quantum computing could be that they become less power intensive for many calculations, even those that can comfortably be done by "classic" computers
The researchers found that their qFlex implementation required 97 MWh to run on Electra and 21 MWh on Summit, whereas the problem could be solved by a NISQ using only 4.2×10−4 MWh. In comparison, the average US household uses 11 MWh of electrical energy per year.
