"This isn't a billboard. It's a power plant."

Here is another clever advertisement. This one is a billboard/solar plant. Yes, you heard right. The billboard has been transformed to a solar plant and generates about 3.4 Kw of electricity during the day. According to Pacific Gas and Electric (PG&E), the owners of the ad, says that is enough electricity for a family of four.

Jennifer Zelwer, Pacific Gas and Electric (PG&E) spokesperson, said that "the energy that is collected by the solar panels actually exceeds the amount used by it on a day-to-day basis." She proudly (I guess) stated that "this isn't a billboard. It's a power plant."
