US Electricity Production by State
I was curious to see what the latest data from the EIA (Energy Information Agency) is telling us. So, I did some quick visualization using Tableau Public. The following chart shows the electricity production by State for year 2011 based on the preliminary data (please footnote for EIA's clarification on this data). The chart shows some interesting characteristics of how different States generated electricity last year.
The chart is interactive. You can use Zoom-out button (-) on the top left corner (it will appear when you hover your mouse over the graph) to see information for Alaska and Hawaii.
If you move the mouse over each State you will be able to see the number of generators and the amount of generation for that State (The darkness of redness in each State is proportional to the amount of electricity generated).
Additionally, you can change the fuel type used for generation by selecting different filter setting on the right to see the predominant type of fuel used by the State.

Which US States are generating electricity using IC (Internal Combustion) engines running on NG (Natural Gas)?
CHPs (Combined Heat Power) being one of my current areas of interest, I also wanted to get a quick answer to the above question from EIA's data.
The X-axis shows States with NG, IC Engine CHPs. Y-axis shows the number of CHPs in each state.
If you move the mouse over to each of the plant represented on the bar, it will also show the Plant Name and the total electricity produced by this plant in 2011. You can explore other scenarios by changing the filter settings on the right.
With current record-low NG prices, I believe the number of generators producing electricity from this fuel is likely to increase significantly.

Footnote:
Clarification on the preliminary data by EIA: This is an early release of the final EIA-923 data for calendar year 2011. The early release is provided for the express purpose of providing immediate access to individual plant and generator data for analysts who use this type of information. The data has not been fully edited and is inappropriate for aggregation, such as to state or national totals. Also, in some cases, data for a certain number of plants and generators has been excluded from this early release pending further data validation. Final, complete, and fully-edited data will be released by EIA later in 2012.
