According to Natural Resources Canada, data centres support every sector of the Canadian economy and consume roughly one percent of the total electricity consumed in Canada. When sizing data centres, they are typically designed to accommodate peak demand. A consequence is that much of the time, the vast majority of servers are idle yet still consuming energy. If one could determine how to effectively turn servers off (and on), there are clearly significant gains to be made, both in terms of direct savings for data centre operators, but also for Canadian society due to the corresponding reduction in greenhouse gas emissions. The tradeoff to consider is that performance may decrease (in terms of waiting times) if servers need to be turned on to cope with rising demand, and that frequently turning servers on and off may reduce the lifetime of the equipment.

据加拿大自然资源部称，数据中心支持加拿大经济的各个部门，消耗的电力约占加拿大总电力的百分之一。在调整数据中心规模时，它们通常旨在满足高峰需求。其结果是，大多数时间，绝大多数服务器处于空闲状态，但仍在消耗能源。如果能够确定如何有效地关闭（和打开）服务器，那么显然可以取得显着的收益，不仅可以为数据中心运营商节省直接成本，而且可以通过相应减少温室气体排放来为加拿大社会带来好处。需要考虑的权衡是，如果需要打开服务器来应对不断增长的需求，则性能可能会下降（就等待时间而言），并且频繁打开和关闭服务器可能会缩短设备的使用寿命。
