I’ve just noticed that last September I followed CC 214 with CC 115. My bad.

1. Solar, wind and hydro could power the world, at lower cost

That is according to an updated study by Stanford University professor Mark Jacobson and colleagues at the University of California at Berkeley and Aalborg University in Denmark summarised by Giles Parkinson.

    it lays out three different methods of not just providing 100 per cent renewables for electricity, but also for heating and cooling, for transportation, and even agriculture, forestry and fishing.

1. Australia’s vast kelp forests devastated by marine heatwave, study reveals

    A hundred kilometres of kelp forests off the western coast of Australia were wiped out by a marine heatwave between 2010 and 2013, a new study has revealed.

    About 90% of the forests that make up the north-western tip of the Great Southern Reef disappeared over the period, replaced by seaweed turfs, corals, and coral fish usually found in tropical and subtropical waters. Continue reading Climate clippings 120

1. South Australia going for broke

Malcolm Turnbull would call it a ‘reckless, irresponsible, ideological frolic’, but South Austria has been running 63% on wind and solar during the last few months, and is going for broke.

Giles Parkinson says SA must, and will, lead world on renewables.

    The Weatherill and Koutsantonis strategy is to embrace new technologies, cheap wind and solar and storage, smart software and smarter management, and put into practice the sort of scenarios envisaged by the CSIRO, Energy Networks Australia and more recently by the storage review commissioned by chief scientist Alan Finkel.

All that can stop Weatherill and Koutsantonis is Nick Xenophon at the next election putting the LNP into office. Continue reading Climate clippings 118

On Monday and Tuesday this week we are going to have the AFR national Energy Summit in Sydney with everyone there, including Josh, Jay, Bill, Andrew Vesey and a different Malcolm Roberts (Chief Executive, APPEA). Should be fun.

The Weekend AFR had about half a dozen articles, led off by an article by Ben Potter, Angela Macdonald-Smith and Mark Ludlow (no doubt pay-walled) which said our energy has become dirty, expensive and annoyingly unreliable. They reckon something has to be done, it’s just that:

the causes identified by Prime Minister Malcolm Turnbull – or unofficial backbench energy spokesman Tony Abbott – are not the same as the causes power industry experts and regulators highlight. Continue reading Climate clippings 117

1. South Australia wants an apology from the PM

On September 28 we had the first anniversary of the dirty big storm the brought down the power pylons in South Australia causing a state-wide blackout, as the Heywood interconnector exceeded capacity and tripped.

Now the state want an apology from the PM. Energy minister Tom Koutsantonis: Continue reading Climate clippings 116

Climate clippings 115: beyond coal

1. Liddell to go

The die was cast at the AGL annual general meeting. Liddell will be closed and not sold.

    Mr Vesey spent the bulk of his address explaining how AGL would replace the capacity lost at Liddell, including new wind and solar farms, up to 750 megawatts of new gas-fired plants and a 100-megawatt upgrade to the more modern and larger Bayswater coal plant nearby. A 250 MW battery at Liddell and demand response will also come into play, he said.

1. Trump’s climate vandalism continues

Trump has picked a Republican politician, Rep. Jim Bridenstine of Oklahoma to oversee NASA, a job that often goes to astronauts or scientists.

    Bridenstine, who is the former executive director of the Tulsa Air and Space Museum and Planetarium, said in a 2013 speech on the House floor: “Global temperatures stopped rising 10 years ago. Global temperature changes, when they exist, correlate with sun output and ocean cycles.”

1. Australia has experienced its hottest winter on record

From the Climate Council – Worsening climate change melts winter heat records:

    The Bureau of Meteorology (BOM) today released its seasonal update confirming Australia has seen the hottest (for mean maximum temperatures) and one of the driest winters on record, with temperatures reaching almost 2 degrees Celsius above average.

    Climate Council CEO Amanda McKenzie said the hottest winter in history was very concerning, given 2017’s string of broken climate records including the warmest July (mean maximum temperatures). Continue reading Climate clippings 213

1. South Australia to get 30MW battery to create renewables-based mini grid

    The Australian Renewable Energy Agency says it is providing $12 million towards the $30 million cost of a major battery storage installation to be located on the Yorke Peninsula in South Australia and create a renewables-based mini-grid with the nearby Wattle Point wind farm.

The battery will pair with the local 90MW Wattle Point wind farm and local rooftop solar PV to form local micro-grid to ensure grid security and so keep the lights on in case the network failures elsewhere in the state. Continue reading Climate clippings 212

1. Planting nearly 100,000 trees per day with drones

We plant about 9 billion trees each year. Unfortunately we also clear about 15 billion, leaving a deficit of 6 billion.

A system of using drones is being developed which could plant trees at 10 times the rate of hand planting and at 20 per cent of the cost by firing germinated seeds into the ground. Continue reading Climate clippings 211
