Submission + - LED Bulbs Lifecycle Energy Costs Calculated (osram-os.com) 1

necro81 writes: The NY Times is reporting that a new report from Osram, a major lighting manufacturer, has calculated the total lifecycle energy costs of LED lightbulbs and found that they are approximately 20% that of incandescents. While it is well known that LED bulbs use a fraction of the energy of incandescents to produce the same amount of light, it has been unproven if the higher manufacturing energy costs made the technology a net gain. The study found that manufacturing and distribution energy costs of all lightbulb technologies is only about 2% of their total lifetime energy cost — a tiny fraction of the energy used to produce light.
