How many watts is an electrolux refrigerator use?

Depends on the primarily on the size and specific features, but should also be affected by settings, ambient temperature/how often it is opened (how hard it is going to have to work, age and maintenance.

E.g., Assuming normal operating conditions my Electrolux 11.5 cubic foot model consumes 109W/hr (which in my particular location costs me about $10 per month to operate).

Look at the label on the back of your specific refrigerator or in the owners manual that came with it.
