Craig Emerson says we can get the gas we need, but is it necessary?
Craig Emerson has an article in the AFR, also on his site, suggesting that politicians need to urgently turn their minds to gas supply in east Australia. Emerson had warned them back in 2014, but they took no notice, and AEMO assured everyone there was no problem.
Suddenly there is. The price of gas-fired electricity threatens manufacturing jobs, and gas is needed to replace coal-fired power. Continue reading Gas, pumped storage and energy futures
Prime Minister Malcolm Turnbull addressing the National Press Club last week, described energy as a “defining debate of this parliament”.
His speech set out Turnbull’s vision for Australia’s energy future – covering renewable energy, “clean” coal, gas, power prices and electricity security. He talked up coal, saying Australia as a big exporter needs to show we are using state-of-the-art clean coal-fired technology.
The Climate Council ran a Fact Check and found clean coal is NOT A THING.
Large-scale wind and solar plants are already cheaper than new “more efficient” coal plants, and waaaay cheaper than coal plants with CCS.
You might expect that from the Climate Council, but Ben Potter in the Australian Financial Review reports that just about everyone is saying the same thing. Continue reading Electricity prices: Turnbull’s central
policy scare campaign
Start stopping now, is the short answer. No new coal mines, oil wells or gas fields, and start decommissioning existing ones now. “Managed decline” is the new imperative.
A new study released by Oil Change International, in partnership with 14 organizations from around the world, scientifically grounds the growing movement to keep carbon in the ground by revealing the need to stop all new fossil fuel infrastructure and industry expansion. It focuses on the potential carbon emissions from developed reserves – where the wells are already drilled, the pits dug, and the pipelines, processing facilities, railways, and export terminals constructed.

Frank Jotzo recently pointed out that if we are to meet our Paris commitments of keeping global temperature rise below 2C we will need to close about one coal-fired power station every year. I believe we have 24.
He was giving evidence to a Senate inquiry into the Retirement of coal fired power stations set up by the Greens and Labor, chaired by Larissa Waters and due to report on 29 March 2017. If you follow the links there is already an Interim Report and 133 submissions available for our perusal. Continue reading Closing down coal
Coal provides 40% of the world’s electricity, with 75% of this capacity deemed “subcritical”, in other words dirty. That’s a little over 1,200 GW of capacity. The IEA believes that we must shut down 290 GW of subcritical generation worldwide by 2020 in order to stay within a 2°C temperature rise.
The Stranded Assets Programme at the University of Oxford’s Smith School of Enterprise and the Environment has identified the power stations, the companies and the countries, so that financers, investors and policy makers can weigh the risks and take appropriate action.
In addition to CO2 production, air pollution and the public pressure to close for that reason, is a risk factor. Finally, subcritical plants use 67% more water. Many are in climatic areas where water scarcity is a risk. Continue reading Stranded assets and subcritical coal
The latest Morgan Stanley report is bullish about the growth of battery storage in the Australian market. They think we’ll have 6.6GWh of battery storage in Australia by 2020, which is what the Australian Energy Market Operator last week predicted for 2035. Continue reading Climate clippings 176

The Powerwall is a 7 kilowatt hour (kWh) lithium-ion-battery system that stores electricity generated from rooftop solar panels (or PV panels) during the day so that electricity can be used at night during the peak-usage times.
Most existing solar panel owners will need to obtain a new inverter to connect with the grid. Continue reading Climate clippings 163
China exponentially increased its use of coal in the early part of this century, so that 64% of its energy comes from coal. Now studies suggest that coal use in China declined in 2014 and may have peaked in 2013. No new mines will be approved in the next three years. Continue reading Climate clippings 162
1. Massive cyber attack on Bureau of Meteorology supercomputer
China is being blamed for a major cyber attack on the computers at the Bureau of Meteorology, which has compromised sensitive systems across the Federal Government. Continue reading Climate clippings 158
French President Francois Hollande did not turn up to give the opening address at a major climate science conference in Paris recently, being otherwise occupied with questions concerning Grexit. Had he been there he may have been able to explain why France has restored subsidies to the French companies building coal-fired power stations in other countries.
As the matter stands, we are told, a coal renaissance is underway which will deliver a 4°C world, or warmer. Continue reading Coal renaissance, as scientists meet and the faithful examine their conscience
