Mega offers you the same energy, just cheaper. So, if you do not take action, others will. (No actors were harmed in the making of this campaign.)
Reason
Many Belgians stay with the same energy provider for years and do not really question the price on their energy bill. How could we open their eyes?
Emotion
Many Belgians do not lose sleep over their expensive energy bill. What if their appliances were fed up using expensive electricity and started to revolt? What if they wanted to make clear that it is time to switch to a cheaper provider?
