Energy Generation Viz: My first published data visualization

A former colleague of mine, Walter Frick, works up in Boston for the New England Clean Energy Council.  As a follow up to a conversation we had, he shared this EIA graph with me. As you can see it is an area chart. I've never been able to understand or read stacked area charts.  (Perhaps because they are often used incorrectly?) So, I downloaded the data for the EIA chart and reworked it. Walter liked it and used it for a blog post for his organization. My first public data visualization!

I know that stacked bar charts are not always the best way to see changes in amounts across the x axis for a particular band. However, I think visually it turned out rather nicely.
