Why I will not be switching my lights off for Earth Hour

The World Wildlife Fund are promoting their annual "Earth Hour" which is due to take place on Saturday 27th March at 8.30pm (local time).  Whilst the positive promotion of this event ticks all the "environmental friendly" boxes, surely the surge from the switching back on of lights at 9.30pm will cancel out most of the "conserved" energy? After all, we've all heard of the power surge after a popular programme on television!! Oh, and don't forget that no major power company will be "switching off" and even if they did, they have preserved energy.


You all know I'm no eco-warrior but I'm not a planet abuser either.  I recycle as much as I can but I have to drive a car to get to work (and there's no way round it).  I tried to make my house more "energy efficient" but the walls are too weak to have cavity wall insulation (the house was built around 1900).  *shrugs*  


This is not a scientific or a protest post, it's just about what I am not doing because I don't think it's worth it.  Instead, I shall look at this picture and think "oh, how beautiful"...


Earth Lights


Edited to add:  I will save an hour's worth of energy by moving my clocks forward one hour tonight (Saturday) in line with the start of British Summer Time so everyone is a winner...
