The Coal Sigils, is the first of The Sigils dedicated to energy security, a series of daily papers scanning the horizon for weak signals related to various issues relevant to the security of societies, polities, nations and citizens. They use Paper.Li as curation platform.
Why a Sigils focused on coal?
According to a new release by the IEA,
“As of March 2012, approximately 40% of the world’s electricity needs were provided by coal. Yes, coal is the second source of primary energy after oil.”
Furthermore, considering the progressive or rapid abandonment of nuclear energy, as in Germany or in Japan, which shut off its last reactor on 5 May 2012, coal could very well see an increase in demand, at least for a few years, until alternative energy mix are implemented.
Besides electricity, coal is also used in steel and aluminium production, in the manufacture of cement, increasingly to produce transport fuels from liquefied or gasified coal (Survey of Energy Resources, Nov 2010, p.3).
The use of coal varies according to regions, with a demand increase forecast in Asia, and, on the contrary, a diminution in the West (without considering the nuclear free policies impact).
The environmental and health impacts of coal mining, processing and usage (World Coal Association, 2005, 2012) make it a highly questionable source of energy, although many efforts are made to struggle against them.
Last but not least, data regarding proved reserves seem to be controversial, which could create surprise,* while the unequal distribution of coal exports (90% originate from six countries: Indonesia, Australia, Russia, South Africa, Colombia, and the United States) create the potential for tension (IEA 2012).
All those points deserve monitoring if we are to avoid surprise and develop proper foresight in energy security.

*Recent surveys tend to emphasise plentiful reserves. However, the November 2010 Survey of Energy Resources, by the World Energy Council details the difficulties surrounding the gathering of data and related assessments, pp.1-3.
