In a speech to the National Press Club, Prime Minister Malcolm Turnbull declared that the key requirements for Australia’s electricity system are that it should be affordable, reliable, and able to help meet national emissions-reduction targets. He also stressed that efforts to pursue these goals should be “technology agnostic” – that is, the best solutions should be chosen on merit, regardless of whether they are based on fossil fuels, renewable energy or other technologies.
As it happens, modern wind, solar photovoltaics (PV) and off-river pumped hydro energy storage (PHES) can meet these requirements without heroic assumptions, at a cost that is competitive with fossil fuel power stations.
On 7th June 2016 another important step was taken towards decarbonising the South Australian economy. Solastor Australia announced detailed plans to build a solar thermal power station at Port Augusta. Continue reading →
What was unthinkable is now unstoppable – Ban Ki Moon, UN Secretary General
His quote resonated among the many speeches that followed French President Francois Hollande’s announcement that we now have a new global understanding on climate – the legally binding Paris Agreement.
Following Copenhagen 2006, it was unthinkable 196 nations would voluntarily sign up to the world’s first global agreement to work together on climate change in good faith, with 189 lodging Intended Nationally Determined Contributions INDCs before Paris.
Yet it’s important to state plainly that the net contribution of all INDCs now in hand still commit the world to 2.7-3 of warming, so we are not out of the woods yet, but at least we are starting to take it all seriously…
Leaving at a more civilized hour from the youth hostel led to a slightly less civilized trip in the shuttle bus from the RER station. Queuing to get past security gave me an idea of the sheer numbers that the organisers are dealing with at the COP21 site at Le Bourget.
Hard to imagine so many meetings, conversations, information and people can fit into a single day. I guess stalwarts who’ve attended numerous COPs take it in their stride.
Today began with a short briefing for our Climate Action Network Australia (CANA) team, before we walked in to meet Leader of the Opposition, Bill Shorten in one of the formal meetings room available for delegations and side meetings.
A formal review of South Australia’s climate change policies and a proposed Low Carbon Investment Plan is underway, with consultation papers available for comment on the YourSay website, until 18 October 2015.
While wind and solar power have made great strides in recent years, with renewables now accounting for 22% of electric energy generated, the issue that has held them back has been their transience. The sun doesn’t shine at night and the wind doesn’t blow year-round – these are the mantras of all those opposed to the progress of renewables.
Now the renewable power billionaire Elon Musk has just blown away that final defence. Last Thursday in California he introduced to the world his sleek new Powerwall – a wall-mounted energy storage unit that can hold 10 kilowatt hours of electric energy, and deliver it at an average of 2 kilowatts, all for US$3,500.
A surprising development in the intermittent nuclear debate has been the announcement by the South Australian Premier, Jay Weatherill, that the state will hold a Royal Commission into the possible expansion of the state’s uranium mining industry to include nuclear enrichment, storage and energy.
It’s surprising because we don’t need a long and expensive inquiry to see that the nuclear industry offers little potential for future growth in jobs or export income.
Coal has played a pivotal role in modernising the global economy. But if we had a second shot at the industrial revolution, would coal be at the centre? Would we design an economy that viewed Australia – as a senior politician recently described – as “an island of coal, floating upon a sea of gas”? Or would we put human ingenuity to the test and generate a sustainable economy powered by the sun and the wind?
