Good point Mark, but what a lot of people don't undertand is that you will be replacing the non-eficient ones a lot more frequently and they will be costing you far more in terms of electricity used. I finally saw the film last night and I must say, if we have to depend on "average Joe" to make simple lifestyle changes then we are truly f*cked. It has to come from government, at least the EU appear to have recognised the problem and are taking appropriate steps. The fact that the Bush administration is intrinsically linked with car manufacturers, oil companies etc means that change from the world's biggest CO2 contributor is very unlikely, so, once again, we're totally f*cked. Happy to lend my copy of the DVD out to anyone interested. Just send me a PM if you want a lend.
