Use Only What You Need
This billboard reminds me of the post from a couple weeks ago regarding space on billboards. I think the message here is brilliant. Not only is the ad eye-catching, but it practices what it preaches. Only one of the four lights on the billboard is being used, which actually does save electricity.
I wonder how Eskom could continue the theme of this advertisement. I envision eco-friendly light-up products as a supplemental campaign, with logo light-up pens for instance. Or, perhaps color-changing or light-up mugs.
