That is, by definition, more energy efficient.
- LunaSea 3y agoNot if you need to produce a new light bulb
- rcxdude 3y agoNot obviously so. The embodied energy of an incendescent lightbulb could easily be dwarfed by the energy used in its lifetime. The relative cost of the bulb and the energy used to run it would certainly point to this being the case.
- bryanlarsen 3y agoTo restate your point: it's highly unlikely that a $1 light bulb contains more than $1 worth of energy.
- Workaccount2 3y agoA $1 dollar bulb can blow through a dollar of energy in about 100 hours. 200 hours if its a 50W. In the technology connections video he does the math to show that long life bulbs are just an all around loss.
- postmodest 3y ago(Bullshit numbers incoming) If one "forever bulb" can only output 10 lumens @10 watts but you need 100 lumens, and a "one year" bulb can create 100 lumens @60 watts, the disposable bulb wins.
