Renewable energy

Community campaigners rallied in Port Augusta on April 30 to make a final call for the South Australian government to build a new solar thermal power plant in the town.

Readers may have noticed that Australia is in the midst of an energy war. On one side are right-wing commentators attacking renewable energy at every turn. On the other side are renewables advocates, quick to retaliate, sometimes without considering the whole story.

The Victorian government announced on March 14 a $20 million tender, to install up to 80MW of grid-scale energy storage by 2018.

It invited proposals from batteries, pumped hydro, compressed air, flywheel, and solar thermal technologies.

But its deadlines, of 30MW expected to be installed by next summer and 50MW by the following summer, are impossible for two of those technologies to meet.

Pumped hydro facilities take several years to build, because dams, tunnels and pipelines would need to be built.

Queensland premier Annastacia Palaszczuk should hang her head in shame. She has proven once again that the word “Labor” in “Australian Labor Party” has no connection with the interests of working people in Australia — or anywhere else.

Palaszczuk headed a delegation to India on March 17 to underscore her government’s support for the Adani company’s proposed Carmichael thermal coalmine. If it is given the go ahead, it will be the largest coal mine in Australia and one of the largest in the world. It would be the first for the Galilee Basin, and it would open the door to more.

According to the Australian Energy Market Operator (AEMO), electricity supply will be threatened as early as next year by “shortfalls in gas”, or failing that, households may face cuts to their gas supply

In public policy, there are many dog’s breakfasts presented as considered initiatives. Rarely, though, are we served up such a self-contradictory, irrational and generally talentless a dish as the new “energy intervention” announced by South Australia’s Labor government on March 14.

Aimed at side-stepping conservative attacks over recent power cuts, the government’s plan makes some provision for storage back-up to underpin wind and solar. But mainly, the $550 million scheme consists of large-scale concessions to fossil fuel interests — in this case, the gas industry.

Generating electricity using renewable energy is now cheaper than using fossil fuels, but mining companies, banks and governments in Australia continue to invest significantly more in coal, oil and gas than wind and solar. 

A new study from the Australian National University suggests that a 100% renewable energy electricity grid for Australia is not only possible, it would be a significantly cheaper option than the current coal and gas-powered network.

The study, by energy experts Andrew Blakers, Bin Lu and Matthew Stocks, proposed a mix of solar PV and wind energy, backed up by pumped hydro as the cheapest option for Australia.

The first few weeks of the Donald Trump administration have been extraordinary, and quite frightening — not just because of the incompetence of a president who appears to be little more than a self-obsessed idiot, but also by the actions of the dangerous ideologues at the helm of the world’s biggest economy and military power.

Right-wing politicians have blown hard on the anti-renewables dog-whistle since February 8, when extreme temperatures in South Australia were followed by rolling electricity blackouts.

Late that afternoon, power demand in the state spiked to near-record levels. From about 6pm, 100 megawatts — roughly 3% of the state’s total demand — was shed for about half an hour.

The list of things renewable energy can be blamed for received a creative contribution from little-known Liberal backbencher Craig Kelly on November 7 when he linked renewable energy with child drownings.

His argument went like this: environmentalists promote renewable energy policies; renewable energy will drive up the cost of electricity; public swimming pools require electricity to filter and heat; higher electricity prices mean pools will have to either cut swimming lessons or charge more for them; fewer children will learn to swim; therefore, more children will drown.

The International Energy Agency (IEA) announced on October 25 that last year, thanks to cost reductions and significant policy support in key countries, renewables have surpassed coal to become the largest source of installed power in the world. This has prompted the IEA to significantly boost its five-year forecast for renewable energy growth.
