I have an UPS, with a 4 hour battery supply.
It's not that I don't care about global warming. I'm convinced there is nothing I can do about it. I unplug my appliences, ok, but are the big industrial companys that are proboly responsible for 90% of the worlds ozone problem going to do a damn thing about it?
Answer is no, not until our goverments make them.
And we all know how soon that is going to happen...
