As this Gasum Biogas campaign points out, there are numerous sustainable sources in the world to power vehicles. Its argument is that petrol need not be obtained for quick automotive consumption where renewable untapped material exists locally.
The natural gas company enlisted the help of Sek&Grey advertising of Helsinki, Finland, to produce a series of three prints which highlight a few places where energy may be obtained. The first ad features an outhouse perched on the edge of a picturesque lake. The second includes a stack of firewood in the forest and the third frames a bale of hay in a field. A gas station hose and nozzle are lodged into the side of each of these rural fixtures. Informing of sources from waste treatment plants, timber scraps and crops, this Gasum Biogas campaign markets its product by suggesting a humble but charming self-sufficiency.
