Due to the unpredictability of the internet, some aspects are over engineered, making it necessary to continually reevaluate processes and energy use. Computers can be made with multi-cores, so when in low use one the cores can turn off, since it takes a lot less power to use one small core and have one core turned off, than to use one big core at 50%. Consumer routers also possess a efficiency problem. Consumer routers are 1000x less efficient than data center routers and even though they are much smaller, there are a million times more consumer routers. To improve the energy efficiency of these devices, it is necessary to either reduce peak power or reduce average power.
