An important observation in relation to PTB Figure 4 is that while net imports of fossil fuels were only
equal to around 12% of DE in 2008, at a finer level of disaggregation of fossil fuels into sepa...
rate
categories for coal, natural gas, and petroleum, net imports of petroleum in 2008 were much higher,
at 140% of DE. This is significant in that petroleum is relatively hard to cost effectively substitute for in
some important applications e.g. transport fuels (Hall and Klitgaard 2012) , and because it is likely to be
the fossil fuel which (in its conventional form via well extraction) reaches barriers to increased production
first (IEA 2011). On the other hand, it is interesting that the region has actually decreased its relative
dependence on imported petroleum since 1970, when net imports where equivalent to over 200% of
DE. This relative decrease in dependency on net imports to the region also holds for fossil fuels overall,
with net imports of fossil fuels in 1970 being equivalent to 36% of DE.
