I working in sales for a recycling compand and we are putting together a "Green Sheet" for our customers to show them the environmental impact of the materials they recycle.

I have already found information on the amounts of different items that are saved by 1 ton of recycled paper.

I would like to give them a "visual" idea of this impact and know how many kilowatts are needed to power the city of Pittsburgh would give them a more realistic idea of what their recycling can do.

Any help you can give me would be appreciated.
