So much to do, so little time
What uses less energy when making a single cup of coffee: heating the water for one and a half minutes in a 800W microwave, or boiling a kettle? I am thinking the former, but I'm also thinking that I need some guidance on issues like this. Should I photocopy or print another copy? Should I switch on the air conditioning in the car or open the windows?

A good question. Intrigued, I tried out our 3kw kettle and managed 4 "cups" (equivalent to 3 normal mugs) in 90 seconds. So not really much in it between the kettle and microwave.
