not that this looks like a good resource at all for specs, but:

supposedly, 50 BTU/hr from 4.25oz of wax and will last up to 24 hours. the candles you're using look significantly smaller than that.
to create the same amount of heat from an electric source, you would need to consume....... 15 watts of energy for the same time period.
if you burned all 16 at once, you would have a combined output of ~1,600 BTUs. this is the equivalent of ~470 watts of electric heat. if you burned through 1 bag a day, the break-even cost compared to electric is that you would have to be spending just under 9 cents/KWH for electricity. this isn't a bad rate for electric, considering i get nailed for 13.3 cents/KWH, but this is also assuming a 4.25oz candle burning with 100% efficiency. those look like the versions that last around 4 hours, so now you need 6 times as many to keep 24 hours of output. so now, 6X9 = 54 cents/KWh just to break even.
never trust facebook science. ALWAYS do the numbers yourself.
