Electricity emissions down, gas and oil emissions up

Australia’s energy emissions have fallen 12% since their emissions peak in 2012, with all of the decline attributable to a 29% drop in electricity generation emissions since 2008, according to the latest Energy Emissions Monitor from Australia. Australian National University.

Emissions of petroleum products and gas both increased in Australia’s five eastern states during this period.

However, in Western Australia, energy emissions continue to rise, as growth in emissions from oil and gas products has offset very modest decreases in emissions from electricity generation.

According to the ANU monitor: “The national electricity market is therefore the only source of significant reduction in energy emissions in Australia.

“In the year to March 2022, grid-scale renewable generation accounted for just under 25% of total generation, and all renewable generation, including solar energy on the roofs, accounted for just under 34%.

State-by-state results show that Victoria and South Australia, the two states with the largest shares of renewables and the largest emissions reductions, had average wholesale prices 25% lower than the others. States in 2020-2021.

Energy futures markets currently expect this price decline to continue for at least another two years.

In renewables, South Australia is unsurprisingly leading, reaching a 62% share of all generation in 2020-21.

Victoria was next with 30%, then NSW with 23% and Queensland with 17%.

All these figures include the contribution of solar on the roof.

Emission reductions from their historic highs, mostly in 2008 or 2009, show a similar trend with the largest in South Africa and the smallest in Queensland, where electricity generation and consumption continued to decline. increase until 2017-2018.

WA is lagging behind in adopting grid-scale solar generation.
