Adding logo to bottom of pages and centering it.

Hello,
I was able to edit the footer.php to allow me to put a badge supporting eco power on my pages and posts. As you can see, I was able to add a linkable Logo into the header.

How do I get it (the eco badge) to center? It would be even cooler if I could put it in the bottom black bar at:
