✔ Electrical Appliances
It's astounding how many people still leave work without turning off their computer or screen - this alone could save approximately £40 per person per year - and it's definitely worth checking power saving settings on your computer (under the 'appearance/display' option inside your computer's 'control panel'). There is also a lot of common equipment that often doesn't get switched of at night or weekends such printers, photocopiers and servers.
In addition, there may be equipment that is occasionally used but is not disconnected for extended periods of time, such as TVs, projectors, and power tools - even leaving goods plugged in but switched off might use a tiny amount of 'phantom' power. It is critical to maintain electrical appliances, and upgrading obsolete equipment can save energy. Cloud storage is typically more cost efficient than having your own servers in many small and medium-sized businesses. This will also save energy, as there will be less wasted data storage capacity, and the large amount of energy used on cooling equipment will be done centrally rather than in many separate locations.
