What uses the most energy in a data centre?
Energy consumption is the biggest expense involved in running a data centre. This is because of the immense costs of running servers and the necessary cooling infrastructure. In fact, data centre energy consumption has grown so much that it now accounts for 3% of the global electricity supply.
So, what are the largest contributors to your data centre energy bill?
Servers/IT Equipment – Servers, storage and networking devices and peripherals are the largest energy consumers in data centres.
Cooling – Data centres generate massive amounts of heat. Advanced cooling systems, including chillers and air conditioning units, are required to prevent overheating.
Power Distributions – Data centres rely on Power Distribution Units (PDUs), including Uninterruptible Power Supplies (UPSs), to distribute electricity and provide emergency power if outages occur.
Lighting – Whilst lighting doesn’t consume as much energy as servers and cooling systems, permanent lighting is required for maintenance, monitoring and accessibility. This fact alone means lighting contributes a large chunk to your energy expenditure.
