Australia’s strong sun

Australia could become a renewable energy superpower.  One factor behind this is that Australia gets stronger sun than most developed countries.

Two world maps superimposed

Here is a strange map that demonstrates this.
http://www.dailymail.co.uk/sciencetech/article-4707544/Antipodes-Map-lets-dig-virtual-tunnel-Earth.html

It is two maps superimposed on one-another. The first is a normal map of the world.  The second map shows, for each point on the first map, where you would be if you drilled straight down through the centre of the Earth to the other side.

The closer a place is to the equator: (1) the more the sun is directly overhead, (2) the more sunshine it gets, (3) the more electricity is generated from each solar panel, and (4) the cheaper it is for that place to generate electricity from the sun.  This is ignoring other factors like how cloudy a place is.

From the map you can see that:

  • Australia is closer to the equator than the developed countries in northern Europe, northern Asia and northern America.
  • Northern Greenland, Canada, Alaska and Russia are as far from the equator as northern Antarctica
  • Melbourne is as far from the equator as southern Spain, so most of Australia gets stronger sun than Spain and most of Europe.
  • Northern Australia is as far from the equator as the border between the Sudan and Egypt.
  • The southern border of the USA is about the same distance from the equator as Port Macquarie (half way between Sydney and Brisbane). So northern Australia gets more sun than the south of the USA.

Manchester in England is as far north as Macquarie island is south

Here is another way of understanding how strong Australian sun is, compared to Europe.  People often think of Macquarie Island, which lies far south of New Zealand, as being in the Antarctic.  Well Manchester in England is as far north (latitude 54 degrees north) as Macquarie island is south (latitude 55 degrees south).  Northern Europe gets very weak sun and if it were not for the Gulf Stream, much of Europe would be very cold.

Australia has quality solar resources

So, considering only the factor of sun strength (closeness to the equator), Australia has better solar resources than most developed countries – and we have other advantages too, which mean that Australia could become a renewable energy superpower.

The great climate activist Bill McKibben  will be in Canberra on Wednesday 2 May and you can book here if you wish to go. I have included two articles by him below.

While the federal government assumes that the National Energy Guarantee (NEG) will be passed by COAG in August, nevertheless, on Monday, the Smart Energy Council (SEC) launched a $500,000 campaign to fight it. The SEC is concerned about NEG’s totally inadequate emission reduction targets. It believes NEG is essentially anti-renewables and could be worse than doing nothing at all as it still allows for the use of coal long past the point it should be kept in the ground.

French President Emmanuel Macron has been in the US and made an impressive speech to Congress on the need for action on climate change. His speech was interrupted frequently by standing ovations. He hopes the US will rejoin the Paris Agreement. Macron will be in Australia shortly.

With the support of Climate Action Monaro, the regional conference of the Nature Conservation Council of NSW is happening in Queanbeyan, on the 26 and 27 of May with the twin subjects of renewable energy and forests.  You can register here. More information is available on their website which will be updated with the program shortly.

The Climate Council has issued yet another report, this time on land-clearing in Queensland and the implications for climate change. The Queensland government is hoping to curb the excessive land-clearing with legislation, but is meeting with stiff opposition, not least from the federal government who is concerned about its effect on farmers (but clearly not concerned about climate change).

I commend the long two-part article by one of Australia’s leading climate activists, Ian Dunlop, below. He argues that our federal politicians and bureaucracy, by failing to act on climate change, are not fulfilling their fiduciary duties to the public.

There’s another article below about social scientist Mayer Hillman who claims that, because of climate change, we’re all doomed. Because it’s a bit grim, the remaining articles are essentially good news stories so you don’t get too depressed.

A massive bushfire to the south-west of Sydney with a 60km front should be concentrating the minds of everyone on climate change. While it may have been deliberately lit, its size is a function of Sydney experiencing its hottest April ever with little rain, which in turn is most likely related to climate change.

The #StopAdani campaign reports that Turnbull’s government is still considering giving Adani up to $1 billion of taxpayer money from Efic (provides finance for Australian exporters). Labor still supports Adani’s dirty coal mine ‘if it stacks up’. So from 30 April  to 13 May local politicians will be confronted with #StopAdani materials everywhere they go. And from 14-27 May there will be posters saying No Money for Adani Actions at Liberal National MP offices. And in Labor electorates (such as ours), watch for Politics in the Pub events.

As you know, COAG meets this week to discuss the National Energy Guarantee. There have been some concessions made, and South Australia under the new Liberal government is weakening in its opposition, so unfortunately it may go through. Fortunately, though, Victoria and Queensland are insisting on strong renewable targets being included. Meanwhile, the ever-splendid Climate Council has released a new briefing paper, “What are Stakeholders Saying About the National Energy Guarantee?”

Don’t forget the great climate activist Bill McKibben will be speaking in Canberra on 2 May at 6pm at the QT Hotel, 1 London Circuit. It costs $28/$20 and you can book here.

The Victorian and federal governments have promised to pump $50 million each into a near $496 million project to gassify brown coal in Victoria and produce just three tonnes of hydrogen. While hydrogen has some virtues as an alternative fuel, ReNew Economy’s Giles Parkinson rightly asks “Has the world gone completely mad

Some of us went to an excellent talk at ANU last week by climate scientist Dr Joëlle Gergis who spoke to her new book “Sunburnt Country” which is about the history and future of climate change in Australia. I commend it to you.

On the international scene, it appears that the Gulf Stream is weakening significantly, probably caused by the intrusion of cold fresh water from melting Greenland glaciers. This weakening will have a cooling effect on western Europe, though the cooling ultimately may be balanced out by overall global warming.

As if it wasn’t bad enough to have a lump of coal brought into parliament a few months ago, 20 or so Parliamentarians led by Tony Abbott, Eric Abetz, Barnaby Joyce, Kevin Andrews and Craig Kelly, have formed the Monash Group to push for a new coal-fired power station. To his credit, Treasurer Scott Morrison (a wielder of coal in the earlier stunt), declared it was not economic and rejected the idea. The next day, the descendants of General Sir John Monash, who was a civil engineer and an Australian military commander of the First World War, complained about the group using the name Monash for their “anti-science, anti-intellectual” proposal.

Despite Morrison’s rejecting the idea of a new coal power station, the Prime Minister clearly thought a sop to the backbench was in order. He is pushing Alinta to buy the ageing Liddell coal-fired power station from AGL so that base-load power can continue after its planned closure in 2022. PM Turnbull wants  another three years or so of it so it coincides with the opening of Snowy 2.0 (pumped hydro). Fortunately, the heroic Andy Vesey of AGL is standing firm and not selling, and using it as a base to develop renewables.

Someone needs to tell the PM that base-load power is not what is required any more, rather dispatchable power is, and old power plants like Liddell do not deliver dispatchable power. And he needs to know that coal-fired power stations caused a surge in airborne mercury pollution, according to a study done in Victoria’s Latrobe valley.

David Spratt, from Climate Code Red, released a report two days ago that finds we will reach 1.5oC warming within a decade, based on a number of recent scientific papers. This of course, was the more ambitious limit of warming (as against 2oC) set by the Paris Agreement. You can read the report here.

One of the world’s leading climate activists, Bill McKibben, is coming to Australia soon. He will speak in Canberra on May 2 on accelerating climate action. He’s always worthwhile but you have to pay.

Good to see our federal MP, Mike Kelly, standing firm against a nuclear power plant for the South Coast. While nuclear power does deliver carbon-free power once built, building the plants uses a lot of energy as well as the decommissioning.  And as he says, the waste and risk issues have still not been resolved.

Meanwhile, it’s been a hot, dry start to the year. Rather than being a source of pleasure as some news readers would have us believe, for anyone who worries about climate change, it simply provokes anxiety.

It is hard to know what is worse – the hypocrisy of an energy company claiming to be green yet trying to prevent coal stations closing, or a Federal Government that preaches the need for reliability and business confidence as it drives investor uncertainty to new heights.
