چکیده انگلیسی:
Energy use of the globalized world economy is comprehensively overviewed by means of a systems input-output
analysis based on statistics of 2010. Emphases are put on the sources of primary energy exploitation, inter
regional trade imbalance of energy use via global supply chains, and sinks of energy use in final demand. The
largest final user turns out to be the United States, compared with China as the leading energy exploiter. The
global trade volume of energy use is shown in magnitude up to about 90% of the global primary energy
exploited. The United States is recognized as the world’s biggest energy use importer, in contrast to Russia as
the biggest exporter. Approximately one third of global primary energy exploited is shown to be embodied in
inter-regional net trade. Japan and Russia are respectively illustrated to be the world’s leading net importer and
leading net exporter of energy use. For China as the leading energy exploiter, about 30% of its exploited energy
is for foreign regions’ final use, and 70% for its own final use. For the European Union as the largest sink region,
nearly 80% of the energy required in its final use is from foreign regions, led by Russia. As reflected in the
results, the conventional perspective based only on the direct energy consumption by region inevitably leads to
inter-regional “energy grabbing” and “carbon leakage”, which raises a serious concern of “regional decrease at
the expense of global increase”. In current context of energy shortage and climate change, this global energy
overview can provide essential strategic implications at the international, national and regional scales for
sustainable energy policy making.
