Lighting key to energy saving

peakoil.com -> news.bbc.co.uk :

A global switch to efficient lighting systems would trim the world's electricity bill by nearly one-tenth, concludes a study from the International Energy Agency (IEA). The carbon dioxide emissions saved by such a switch would dwarf cuts so far achieved by adopting wind and solar power. "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. "19% 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."

For the individual, the most obvious switch to make is from incandescent bulbs to compact fluorescent systems (CFLs), marketed in many countries as "energy-saving bulbs". "The overall cost of 10,000 hours of light provision from incandescents is 85 euros," said Paul Waide, "but for CFLs it's 25 euros, because they use so much less energy, and because you might have to buy only one CFL for every 10 incandescents."
