How much electricity does lighting cost compared to other electrical items

  1. May 29, 2008 #1
    Like a fridge, freezer, or washing machine?

    I was wondering if lighting would be a significant consumer of electricity of a regular house like say 10-20%?

    Estimate number of lights and their power, number of hours per month - that will give you kWh consumption. Compare it to the total from the electricity bill for the last month and you will know.
