Telge Energi - a green energy campaign that I like...

I travelled on the tube today and saw a great ad by Telge Energi, a swedish green energy provider. I will post a picture of the campaign asap.... and I call it the 'thumbs-up' campaign because the print always includes that particular symbol. So, why is it good then? Well, the ads are interesting and I think they are effective due to the following reasons. Firstly, they are noticeable and make the reader feel involved and positive about green energy. Secondly, they made me and I also think they make other consumers interested in how we can in one easy step (contact Telge...) be greener and therefore nicer to the planet simply by choosing Telge Energi. Simple and effective!
