We're working to transform how we light our world. Lighting accounts for nearly 6% of global CO2 greenhouse gas emissions, or 1,900 million tons of CO2 per year--which is the equivalent of CO2 emissions from 70% of the world's passenger vehicles...

"The main barriers to acceptance are technology risk aversion, outdated lighting standards and capital investment"... in other words, doing the right thing will be always less important than money :(

> Lighting accounts for nearly 6% of global CO2 greenhouse gas emissions
= really? (( i might have guessed 5% of global *electricity*. maybe))

anyway, note that a large and growing %age of the "Lighting" is used not by consumers/their_households but by businesses and industry. (( In Germoney, couple of years ago, roughly 1/3 each of electricity was consumed by persons/shops&businesses(?) orig.:"Handel&Gewerbe" =?commerce and crafts/industry -- for US add a 4th sector: military ))

> 6% of global CO2 greenhouse gas emissions, or 1,900 million tons of CO2 per year-
= not well put.
"CO2 greenhouse gas" is a whatyoucallthat.. Pleonasm (if memory serves)
" 1,900 million tons of CO2 per year- " == " 1.9 Gt/y CO2 " (in a more reasonable notation)

if 6% = 1.9 then 100% = 32, which figures about OK:
(WP:) In 2010, 9.1 Gt of carbon (33.5 Gt of CO2) were released from fossil fuels and cement production worldwide, compared to 6.2 Gt in 1990

increase 6.2 to 9.1 in 20 years = plus 47 % = plus 1.9 % p.a.; (WP)
total global GHG emissions growing at 2% p.a. (-- "Beyond Growth or Beyond Capitalism?" By Richard Smith)
==
If every last lightbulb were changed, today, globally, how long would it take for population growth to bring back electricity consumption (aka. "need") to the starting-value? ("everything else being euqal/constant)")
--
from 1990 to 2008, the average energy (ab)use per person increased 10% while world population increased 27%

Again, very informative, thanks!

In Australia we have been forced to use compact fluorescent light bulbs to save energy, but they cause environmental damage in production and post use. They don't work well, can't be dimmed and the light is not 'natural' or pleasing. Every single one of them is made in a country we boycott, so we stocked up on old light bulbs and candles a few years ago.

Thanks to your article, Frans, I had another attempt to find LED bulbs produced elsewhere that I could purchase here, and I found some! We will buy a couple and gradually replace our lighting with them.

Now what will I do with 6 boxes of candles?!

For some incredibly beautiful LED artscapes, have a look at these: http://www.boredpanda.com/led-light-tunnel-japan/

Ah, here's the counterpart to the CFL article. This provides some useful statistics, but seems primarily concerned with outdoor lighting. Comparisons to CFL and incandescent lighting in terms of energy savings, cost savings, environmental costs from production and post-production, light output and tone, and endurance would have been helpful, especially in regards to the consumer.

Our technology advances are skipping generations of dreams, disappointments and "keep trying"s.
