I welcome the Government's action to penalise the biggest users of electricity. The arrival of the mega data centre and expected rise in capacity and energy needs of big business will only increase the amount of electricity needed, making efficiency measures all the more urgent.

There is concern that being more energy-efficient will compromise resilience, but this is not necessarily the case. For example, the concept of the "lights-out" data centre was developed to reduce the risk of downtime, yet it also offers environmental benefits.

Companies must blend business requirements with an obligation to reduce their impact on the environment.
