Assistance needed.
Since this is not my area of expertise, I searched Google under the key words "energy bar graphs" to get these possible sources:

http://www.docstoc.com/docs/1019446/MAKING-A-BAR-GRAPH
http://strandmaps.nsdl.org/AAAS-Collection/NSDLbenchmarksContent.jsp?alls=35&bm=SMS-BMK-0203&map=SMS-MAP-1422&tab=0

Within these sites, use <Find> for "energy bar graph."

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

I hope this helps. Thanks for asking.
