Understanding what electricity does for your business in real terms is the first step towards a solid energy efficiency plan. To give you an idea of how powerful a kWh is for example, you should consider that only ¼ of a kWh will run a laptop (rated 22 Watts) for 11 hours. More specifically, 1 kWh will handle the following tasks: Will run a photocopier/scanner/fax machine (rated 375 Watts) for 2 ½ hours. Will run a PC desktop with a traditional 17” CRT monitor for 5 ¾ hours or a PC desktop with a 15’’ flat screen LCD monitor for 8 hours. Will run a wall-mounted electric convector heater for 30 minutes. Will run an electric cooker oven for 17 minutes. Will run a power shower pumped from an immersion tank (rated 450 Watts) for 2 ¼ hours. Will run one T8 fluorescent lamp for 31 hours, 15 minutes. Did this answer your question?
