FACT CHECK: How much incandescent bulbs really cost (march, 2013)

FACT CHECK: How much incandescent bulbs really cost (march, 2013)

With so much misinformation consumers are not being given good information about lighting. Especially the particularly poor reporting about the ongoing elimination of 100w, 75w, 60w, and 40 incandescent lamps. In fact, incandescent lighting is not being eliminated or outlawed, but what is being eliminated are the least efficient, commonly used versions. As long as people pick the right bulb for the result they want, in terms of lighting quality and color, the alternatives available right now can do everything that incandescent do while costing much less and consuming far less energy.A typical misinformed assertion will be that, “a 75w incandescent lamp is less expensive than a CFL [compact fluorescent lamp]”.  This is irresponsible, given that the statement is true only if you use the incandescent lamp for something like a paperweight. People need to know not the cost of buying one type of lamp or another, but rather the cost of owning and using one type lamp or another. Once people have that knowledge, they quickly realize that the incandescent lamps they grew up with are just about the most expensive there are, not the least expensive.The table below can also be of value. It compares the ten-year cost...

Lighting - The Key to Energy Saving (January, 2013)

Lighting - The Key to Energy Saving (January, 2013)

A global switch to efficient lighting systems would trim the world's electricity bill by nearly one-tenth.That is the conclusion of a study from the International Energy Agency (IEA), which it says is the first global survey of lighting uses and costs.The carbon dioxide emissions saved by such a switch would, it concludes, dwarf cuts so far achieved by adopting wind and solar power. Better building regulations would boost uptake of efficient lighting, it says."Lighting is a major source of electricity consumption," said Paul Waide, a senior policy analyst with the IEA and one of the report's authors."Nineteen percent of global electricity generation is taken for lighting - that's more than is produced by hydro or nuclear stations, and about the same that's produced from natural gas," he told the BBC News website.The carbon dioxide produced by generating all of this electricity amounts to 70% of global emissions from passenger vehicles, and is three times more than emissions from aviation, the IEA says.Not many inventions last for more than 100 years without major modifications.The incandescent light bulb, developed a century and a quarter ago by luminaries including Sir Joseph Swan and Thomas Edison, is one, and still produces almost half of the...
