I already wrote in the past that a couple of times that I'm worried about the insane high energy consumption of DSL and WLAN hardware that's supposed to run all the time.

Recently, I switched my internet provider from O2 to Kabel Deutschland and got new hardware. I made some findings I found interesting:

It seems very many power supplies today have a label on their energy effiency. If you find something called "EFFIENCY LEVEL: V" - that's it. V is currently the best, I the worst. Higher values are reserved for the future (so this is much more intelligent than the stupid EU energy label, where A stands for "this was the best when we invented this label some years ago"). I haven't tried that yet, but from what I read it seems worth replacing inefficient power supplies with better ones.

The cable modem I got eats 4 Watts. Considering that it's the crucial part that cannot be switched off as long as I want to be able to receive phone calls, I consider this rather high. The power supply had effiency level IV. If anyone knows of any energy saving cable modems, I'm open for suggestions.

I was quite impressed by the router I got for free. It's a D-Link 615 and it's using 2,4 Watts with wireless and 1,4 Watts without. That's MUCH better than anything I've seen before. So at least we see some progress here. (and for people interested in free software: it seems at least DD-WRT claims to support it and the other *WRT projects are working on it)

Though I still fail to understand why there can't be a simple law stating that every electronic device must put information about it's energy consumption on the package.

I'm currently in Scottland on a trip through the UK. I'm trying to get some contacts to the much more active environmental movement here. For those who don't know, the UK has probably the most active climate movement in the world. I just came from a gathering in the Lake District and now I want to visit a protest site against open cast coal mining in Mainshill.

Afterwards I'll visit the Climate Camp.

It's quite interesting to see discussions here. The main topics at the moment are the third runway at the heathrow airport (see e. g. Plane Stupid) and the building of a new coal plant in Kingsnorth (done by the german company e-on). I heared quotes like »we shouldn't wait till they build the new plant, they're burning coal every day in the existing ones«, which is a large difference compared to the discussion in germany.
