Wood Mackenzie says 2014 was a significant year for China as economic rebalancing led demand growth - for a range of major energy commodities - and GDP growth decoupling significantly for the first time.

Over the past two decades, commodity demand growth had maintained relatively proportionate annual increases to GDP growth. In 2014 however the pace of power, gas, coal and diesel demand increase fell more drastically than the slight GDP moderation, beyond expectations.

Wood Mackenzie expects gas demand will recover in one to two years as the key drivers of slower growth are mainly cyclical but power, coal and diesel demand will see their outlook change notably over the long-term due to major structural changes in the economy and policy. Global energy sector will need to identify which changes are structural or cyclical in to determine future demand patterns and opportunities.
