How many lightbulbs are there in the world

There are still about 8 billion common light bulbs in use, worldwide. By an average wattage of 40 Watts per bulb, they consume about 53 Million MW of electricity per day.

By using the latest LED bulb technology, this figure can be reduced by 80%, so the CO2 emissions. LED bulbs are actually not expensive at all, if we calculate the life span compare with the maximum life span of an common light bulb, the individual consumer earn money already after a short time. Not to mention what it mean for our natural environment in a good way. A quality 9 Watt LED bulb cost about 7,00 to 9,00 USD by a life span of 50.000 hours and more.
