Throw away attitude
"Rupert (W.Yorkshire)" writes
If you believe saving energy is important then I can assure you that brand new white goods (Fridges/freezers/washers etc) are considerably more efficient than 10 year old models. If you're starting from a position of needing a new fridge, yes. How do the calculations go when it's a choice of a) using the old one another 5-10 years, compared with b) manufacture a new one 5-10 years earlier than otherwise, and dispose of the old one 5-10 years earlier -- Kay |

How do the calculations go when it's a choice of a) using the old one another 5-10 years, compared with b) manufacture a new one 5-10 years earlier than otherwise, and dispose of the old one 5-10 years earlier From New Scientist Print Edition 12 May 1990 "To a householder, the power used to cool food may seem modest: after all, even a large fridge-freezer costs only about 12 pence a day to run. But there are more than 30 million fridges, freezers and fridge-freezers in British homes, which between them consume more than GBP 1 billion worth of electricity in a year. The average demand on the national grid, measured at consumers' meters, is at least 2000 megawatts, the equivalent of the continuous output of two large power stations. If these two power stations generate electricity from coal, Britain's fridges and freezers are responsible for emitting about 15 million tonnes of carbon dioxide a year into the atmosphere...." and... "...Going one better, Britain could replace its existing stock of 30 million fridges, freezers and fridge-freezers with state-of-the-art appliances and run the lot on just 200 megawatts. This means that we would not need about 1800 megawatts of power and that we could therefore avoid building about GBP 5 billion worth of power stations and infrastructure." What the cost of disposal of the old fridges would be is anybody's guess. -- Tim C. |

So the question is how much energy is required to replace and distribute "new for old fridges" to everyone. =NFO (LE=Life expectancy) If NFO 1800 x LE then it's a good job. We must take into account the anti depressant drug manufacture energy cost for all the overworked and then redundant fridge production workers. |

I doubt that any correct calculated data is available. Perhaps all goods should have a sticker which states "Energy used to make this":-) Incidentally I did replace and old fridge with a new one on the basis that the energy saving cost (to me) negated the new cost before the estimated demise of the new fridge. I think that demonstrates the general misconceptions about environmental and economic issues:-) |
