Coal is set to be the world’s largest single source of energy by 2020, according to a new report, with no sign of demand waning.
Even under scenarios of slowing economic development, the International Energy Agency (IEA) predicts that China and India will drive coal consumption upwards, with the fuel reaching parity with oil globally by 2017.
Coal emits more greenhouse gases and other pollutants than other fossil fuels, which will make it difficult to expand coal use and meet climate change targets without intervention.
“Carbon Capture and Storage (CCS) technologies are not taking off as once expected, which means CO2 emissions will keep growing substantially,” said Maria van der Hoeven, executive director of the IEA.
“Without progress in CCS, and if other countries cannot replicate the US experience and reduce coal demand [by swapping for gas], coal faces the risk of a potential climate policy backlash,” she said.
The IEA predicts that in order to keep carbon dioxide levels below the 450ppm recommended by climate scientists, coal use will have to peak before 2020 and then fall by more than a quarter during the next decade.
Commitments to reduce greenhouse gases, expected through the UN negotiations process in 2020, could put a cost on emissions that makes coal less attractive.
The low carbon price at present would not be sufficient to do this leaving a switch to gas, increased renewables and CCS as the only alternative to meet energy demands without incurring the full impact of coal on the climate.
The IEA calls India’s combination of energy poverty, huge population and large domestic supplies “the perfect cocktail to boost coal consumption”.
Enabling the country to develop while also keeping the world within the 2°C limit of warming, as recommended by climate scientists could require the transfer of CCS technology to India.
Technology transfer proved a thorny issue in Doha with developed nations unwilling to open discussion on Intellectual Property Rights.
Unconventional gas sources, which have helped the US become the only nation with falling coal consumption, offer another route to reducing the environmental impact of coal.
Critics say however, that investment would be better made in renewables than “locking in” the carbon output of new gas infrastructure for the next 40 years.
Worrying finding by @iea that coal will be 1st energy source by 2017- int’l efforts must address this but switching to gas is not enough

Commenting on the UK’s own recent energy reshuffle, Nick Molho, head of energy policy at WWF-UK warned against a dash to gas.
“Not only is investing in renewable forms of energy a good way to manage costs, it will also create jobs, boost the economy and, most importantly, play a major role in tackling climate change,” he said adding that in Britain’s case, gas should only be a transitional fuel.
“Whilst gas plants emit less carbon than coal plants, gas is still a carbon-intensive fossil fuel.”
