Annual emissions were 5.5 per cent higher than in the year to June 2014, when the Coalition killed the carbon price introduced by the Labor government, to much acclaim from the government (see picture above).

This startling jump in emissions comes despite the fact that Australia has signed up to the Paris climate agreement, which seeks to limit global warming to 2°C, and if possible 1.5°C. Energy emissions, according to the International Energy Agency, have flatlined for the past two years.

The rise in emissions also comes amid rising global CO2 levels, soaring temperatures, and the most serious coral bleaching event ever witnessed in the Great Barrier Reef.

Saddler blames the rise in emissions on a number of factors. One is the removal of the carbon price, which paved the way for more burning of coal, black coal in particular.

Another is the rise in coal generation in Queensland to support the exports of liquefied natural gas – which will contribute an extra 8 million tonnes of CO2 equivalent a year.

A third is the increase in demand, driven largely by LNG requirements in Queensland but also rebounds in peak demand in other states, particularly in response to the unusually hot summer worsened by the “El Niño” effect, which has exacerbated the rise in global temperatures.

“There can be little doubt that the period of falling demand for electricity across Australia has now ended,” Saddler writes. “In the year to March 2016, total NEM annual demand increased for the thirteenth successive month.”

Saddler says brown coal generation actually fell, but this was largely to do with the loss of the interconnector to Tasmania. This is expected to be quickly reversed when the cable is fixed, possibly in June, because Tasmania’s hydro levels are now down to record lows, and it has not invested enough in other renewable energy generation to compensate for this.

In the year to March 2016, black coal generation supplied 53.1 per cent of NEM electricity and brown coal supplied 23.0 per cent. The total coal generation was 76.1 per cent, compared with a minimum of 72.3 per cent in the year to July 2014, the last year of the carbon price. Gas supplied 10.7 per cent of NEM electricity in the year to March 2016, the lowest share since July 2010. Hydro generation increased slightly in all three states with major hydro capacity. Saddler said wind generation fell slightly, probably because of the unusually hot, still weather across southern Australia throughout the first two weeks of March. “A year has now passed since a new wind farm came on-line in the NEM, the longest such period for over a decade,” Saddler noted. Indeed, the only new wind farm to come on-line has been the small Coonooer wind farm in Victoria, courtesy of the ACT government’s reverse auction program. All other investment has come to a halt because of the Coalition’s fiddling with the renewable energy target.
