It Takes 714 Pounds of Coal to Run a Light Bulb for a Year
How Stuff Works: How much coal is required to run a 100-watt light bulb 24 hours a day for a year?
The answer? About 714 lbs. of coal. Let’s say you don’t run that one light bulb non-stop, but only for about 10 hours. That’s still almost 300 lbs. of coal. I can very easily imagine that I at various locations and times run at least 100 watts of electricity through light bulbs at least 10 hours a day every day. That’s a lot of coal.
Also, here’s a link from How Stuff Works about how much energy a transformer pulls, regardless of whether the appliance is on or not.
Oh, and FYI: A Google search on “What the fuck is a what?” doesn’t result in anything informative.
