2.8% of the supply costs of other renewable energy such as wind power and solar energy decreased significantly, and the competitive advantage began to show. The proportion of this increased from 1.4% in 2010 to 2.8% in 2017, an increase of 1.22 percentage points. It is estimated that the proportion of fossil energy in the global primary energy consumption structure will continue to decline in 2017, from 86.5% in 2010 to 85.3% in 2017. The proportions of coal and petroleum dropped by 1.3 percentage points and 0.21 percentage points respectively, and the proportion of natural gas rose by 0.8 percentage points. Non-fossil energy share
