It remained relatively constant until the early 2000s when the share began to decline, hitting a low of 17.8 per cent in 2011 as the consumption of fossil fuels to meet growing energy demand increased. A key factor behind this downward trend was the rapid increase of coal supply in China, which, in 2014, accounted for more than 30 per cent of the entire region’s primary energy supply. In the following years, consumption of renewable energy began to gain traction, with its share in the energy mix climbing to 18.3 per cent in 2014 (figure 4.1).
