Second, existing technologies that use coal more efficiently can be deployed, particularly in the power sector, which accounts for two - thirds
of global coal use.
It wasn't long ago that everyone
expected global coal use to rise for decades to come, and now it's looking increasingly likely that the coal boom is over.
This year, for the first time, oil major BP forecast a peak
in global coal use in the early 2030s.
The IEA continues to see an increase in
global coal use by 0.2 % per year, and says China's coal use will continue to make up more than half of the country's total power generation, with Australia remaining the largest coal exporter, followed by Indonesia.
In its latest energy outlook, BP saw
global coal use peaking around 2025 - 2030, whereas the recent trend suggests a peak could have been reached already in 2014.
The world added a record amount of energy from renewable sources in 2016 and
global coal use fell again, according to the 2017 BP Statistical Review of World Energy, published earlier this week.
Already,
global coal use appears to be plateauing, and global oil use will likely follow suit in the next decade as countries ratchet up their CO2 targets.
By 2050, cities could cut annual GHG emissions by 8.0 Gt CO2e over what national policies are currently on track to achieve, the equivalent of cutting
annual global coal use by more than half.
Divergent coal use trends mean that Asia's share of
global coal use rose from 24 % to 63 % during this period (see chart).
Today, the high powered Global Commission on the Climate and Economy released its flagship report
on global coal use and the economy: The New Climate Economy.
For instance,
global coal use would have to peak before 2020; power plants and factories would have to get a lot more efficient; things like nuclear power and renewables would have to expand at an even faster rate.
