An 18 credit quarter has left my blog pretty inactive over the past few months but I decided to post this Google motion chart on world energy usage a while back. My inspiration was Hans Rosling and his awesome TED presentation on life expectancy vs income over the past 200 years. I decided to teach myself how to use Google Documents to model this kind of historical data after my summer internship in market research. Gapminder also has a downloadable version of the software and dataset he used for that presentation.
You can view energy use from 1980 to 2008 by country in total, per capita, and broken down by oil, coal, gas, and renewables. The full chart and data set can be found at: http://goo.gl/9uaAT
