The size of the energy challenge

Following on from Doug Farquhar’s recent guest blog on the role of ICT in meeting the global energy challenge, this morning I spotted this graph.  It was produced a couple of years back for the US Government’s Energy Information Administration (EIA) and clearly shows the magnitude of the challenge to come over the next 20 years.

The graph shows the rapid decline of liquid fuel sources with key traditional oil supplies reducing from c.80 million barrels per day to just 30 million.  Whether alternative energy sources can fully plug the gap remains dubious…

The original graph produced for an EIA Energy Conference in 2009 can be found here.
