How much electricity does lighting cost compared to other electrical items

AI Thread Summary
Lighting can account for a significant portion of a household's electricity consumption, typically estimated between 10-20%. To determine its exact impact, one should calculate the total kilowatt-hour (kWh) usage by considering the number of lights, their wattage, and the hours they are used monthly. This consumption can then be compared to the overall electricity bill to assess lighting's contribution relative to other appliances like fridges, freezers, and washing machines. Understanding this comparison can help homeowners manage their energy usage more effectively. Accurate calculations are essential for making informed decisions about energy consumption.

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.

Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a list based on other article predictions. You can also leave your prediction here.

Thread 'My experience as a hostage'
I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and programming for various companies, including Frito Lay. Frito had purchased a snack food plant near Lima, Peru, and sent me down to oversee the upgrades to the systems and the startup. Peru was still suffering the ills of a recent civil war and I knew it was dicey, but the money was too good to pass up. It was a long trip to Lima; about 14 hours of airtime...
