“Coal met nearly half the rise in global energy demand during the first decade of the 21st Century,” said the International Energy Agency (IEA). Wind, solar, and gas have yet to change the overall picture.
The IEA said “insatiable demand” from Asia’s rising powers will gobble up a further 1bn tonnes each year by 2017, equal to the entire consumption of the US and Russia today. “If no changes are made to current policies, coal will catch oil within a decade,” it said.
By a rough rule of thumb, coal produces 238 tonnes of carbon per gigawatt hour (GWh), compared with 207 for heavy oil and 99 for gas. The IEA says coal already accounts for 43pc of global CO2 emissions.
“The situation is utterly dire,” said Jeremy Leggett, head of the UK Task Force on Peak Energy and Climate Change. “The window over the next decade is absolutely crucial. The danger threshold is a two-degree rise in average temperatures above pre-industrial levels by the end of the century. We’re currently on track for a rise of six degrees. The cognoscenti in the scientific world are terrified,” he said.
