Yesterday I had some topics of which I immediately thought "this I have to comment on", but today, after a good nights sleep, I have no clue what they were. I suppose that puts it all in perspective and means they weren't that important after all?
Ow... I just recalled one topic : the "Lights out around the world for 5 minutes" movement that wanted to make a statement about energy consumption and light pollution. I turned off some lights at work from 19h55 till 20h00, and asked a colleague in another building to do the same. Unfortunately, 30 minutes later a thick fog was forming outside which made me turn on additional lighting on the site perimeters, thus totally invalidating whatever energy saving we had done before.
Apart from that, later in the evening I learned that turning off the lights for 5 minutes and turning them back on actually consumed more energy than just leaving them turned on. Net result : a higher energy consumption, but less light pollution. The overall idea was to awaken and inform people on the topics of energy use and light pollution so I suppose that actually worked, but maybe next time a middle ground should be found between informing and actually saving as well?
If I recall the other topics I wanted to tell you about, I'll be making updates to this post, or even write a new one - depending on how much I want to elaborate on them.
