Throw away attitude

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 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. What about the comparative cost of buying supermarket vegetables, some of which have almost circled the earth and been frozen and stored against storing your own home grown vegetables in a deep freeze? -- Martin Surely we need to make a comparison of the environmental cost and not a financial cost. The two things should not be mixed up. |

Following up to "Rupert \(W.Yorkshire\)" :
Surely we need to make a comparison of the environmental cost and not a financial cost. The two things should not be mixed up. Of course. They can be related however. -- Tim C. |
