We could be among the world's climate change winners

In the dim distant past, politicians got themselves elected by showing us a Vision of Australia’s future that was brighter and more alluring than their opponent’s.

These days the pollies prefer a more negative approach, pointing to the daunting problems we face and warning that, in such uncertain times, switching to the other guy would be far too risky.

We’ve gone from “I’m much better than him” to “if you think I’m bad, he’d be worse”. Maybe they simply lack any vision of the future beyond advancing their own careers.

Management-types tell us we should conduct “SWOT analysis” – considering our strengths and weaknesses, opportunities and threats. But we’ve become mesmerised by the threats and incapable of seeing the opportunities. Such a pessimistic mindset is crippling us when we could be going from strength to strength.

Take climate change. It, of course, is a threat – to our climate, and hence to our comfort and our economy – but think a bit more about it and you realise that, for a country like ours, it’s also a new gravy train we could be climbing aboard.

The stumbling block is that responding to climate change requires change – and no one likes change, especially those who earn their living from the present way of doing things.

So, what more natural reaction than to resist change? Economists are always warning politicians not to try “picking winners”. In reality, they’re far more likely to resist change by spending lots of money trying to prop up losers.

Start by denying that change is necessary. Global warming isn’t happening, it’s just a conspiracy by scientists angling for more research funds.

Nothing new about heatwaves, bushfires, droughts, floods and cyclones – they’ve always existed. They’re becoming bigger and more frequent? Just your imagination.

What you’re not imagining is the ever-higher cost of electricity. But that’s just because those ideologues imposed a carbon tax and are making us subsidise renewable energy. Get rid of the taxes and subsidies and the cost falls back to what it was.

And those terrible wind turbines. They’re unnatural and unsightly, they kill rare birds and their noise endangers farmers’ health.

Renewable energy is unreliable because it depends on the wind blowing or the sun shining. You need coal for steady supply. With the greater reliance on renewables, where do you think the blackouts are coming from?

And renewable energy is so expensive. Coal-fired electricity is much cheaper. Plus, we’ve got all our chips stacked on coal. We’re world experts at open-cut coal mining. Our coal is much higher quality than most other countries'.

Coal provides jobs for 30,000 workers. There are towns desperate for jobs who’d just love another coal mine. And, of course, we’ve still got huge reserves of the stuff that’s of no value if it stays in the ground.

Some of these claims have always been untrue, some are no longer true and some are less true than they were.

Just this week, for instance, a report from the independent Grattan Institute has debunked the claim that “outages” are being caused by renewables, saying more than 97 per cent of outage hours can be traced to problems with the local poles and wires that transport power to businesses and homes.

While it’s true that power from existing coal-fired generators is dirt cheap, many of these are old and close to the end of their useful lives. They’re not being replaced by new coal generators because there’s too much risk that the demand for coal-fired power will dry up before the generators have returned the money invested in them.

The latest report from the CSIRO says the lowest-cost power from a newly built facility is now produced by solar and wind.

The cost of solar, battery storage and, to a lesser extent, wind power, has fallen dramatically over this decade, partly because of advances in technology but mainly because of economies of scale as China and many other countries jump on the bandwagon. These falls are likely to continue.

This has gone so far that the old arguments about the need for a price on carbon and subsidies for renewables are being overtaken by events.

Installation of renewable generation is proceeding apace, with all renewables’ share of generation in the national electricity market jumping from 16 per cent to 21 per cent, just over the year to December, according to Green Energy Markets.

So, as the economist Professor Frank Jotzo, of the Australian National University, has said, coal is on the way out. The only question is how soon it happens.

According to our present way of looking at it, this is disastrous news. But not if we see it as more an opportunity than a threat.

Professor Ross Garnaut, of the University of Melbourne, has said that “nowhere in the developed world are solar and wind resources together so abundant as in the west-facing coasts and peninsulas of southern Australia.

“Play our cards right, and Australia’s exceptionally rich endowment per person in renewable energy resources makes us a low-cost location for energy supply in a low-carbon world economy.

“That would make us the economically rational location within the developed world of a high proportion of energy-intensive processing and manufacturing activity.”

Too many stuff-ups about to put economic reform into reverse

I have bad news and worse for advocates of micro-economic reform. First, the jig is up. There'll be few if any further major reforms. Second, the backlash against mounting wreckage from failed reforms is about to begin.

Since the reform push has degenerated into little more than business rent-seeking – let's cut tax on business and increase it on consumers; let's push the legislated balance of power in industrial relations further in favour of employers – it's neither surprising nor regrettable that voters have called a halt.

Micro reform has lost all credibility with voters. Most oppose company tax cuts for big business, cuts in penalty rates and a freeze on the minimum wage. Neither side of politics will pursue these "reforms" with any enthusiasm.

Economic rationalists will blame all this on irrational populism, but if they were more honest with themselves they'd admit the economic case for bizonomic​ reforms – what's good for business must be good for the economy – is debatable and often unconvincing.

And who could blame the public for holding economists accountable for all the stuff-ups committed in the name of reform over the years: the implosion of the deregulated wool price scheme, the wasteful public-private partnerships, the dubious effectiveness of the Job Network, the disastrous admission of for-profit providers of childcare.

The dodgy education businesses selling access to permanent residence to foreign students, the "contestable" pink batts scheme, the failure of encouraging competition between government and private schools, the huge rip-offs of students and taxpayers arising from federal and state efforts to make vocational education and training "contestable", the privatisation of airports and ports with their monopolies intact.

Economic rationalists are so heavily into confirmation bias they've managed not to notice this record of disasters, but they'll be hard pressed not to see the next one, when for-profit providers rip off the disabled in the name of making the National Disability Insurance Scheme "contestable".

Last week the former high priest of micro reform (and Productivity Commission boss) Gary Banks attacked a politician for daring to blame the failures of energy policy on the private sector's lack of enterprise.

Leaving aside his one-eyed criticism of government subsidies for renewable energy (while just happening not to notice the implicit subsidy of fossil-fuel generators arising from the absence of a price on carbon), Banks was right.

The blame must go to the econocrats who designed the national electricity market and the politicians who took their advice.

That we've gone from about the cheapest to about the dearest electricity – and that without a price on carbon – can be blamed on the malfunctioning of micro reform.

The "market" is the utterly artificial creation of government, run by several government agencies with a 6000-page rule book, responsible to a committee of nine governments.

The reformers' wholesale electricity market seemed to be working well, but now lacks the flexibility to cope with energy emergencies. The price regulation of largely privatised natural monopoly network operators was gamed for years before the regulators woke up, and price competition between electricity retailers is weak and margins high.

Historically, economic rationalists under-rate market failure, but are highly conscious of "government failure" – where government intervention intended to correct market failures ends up making things worse.

This is the rationale for micro reform. Governments have mixed objectives, with little motivation to keep things efficient. Much better to leave it to the private sector, driven by the profit motive to put efficiency above all else.

Really? Economic rationalists and econocrats are naive, partly because many of them have never actually worked for the private sector, and are shocked to discover how powerful is the profit motive in motivating business people to game the system, look for loopholes and, far too often, simply break the law.

Private businesses are always overbidding for privatised businesses and underbidding for contracts to provide government services. Governments think this is terrific, until the businesses wake up to their error and try to extract some profit by overcharging or cutting quality, exploiting the incomplete contracts they signed.

Much of this is bureaucratic incompetence, but it's also conservative governments seeing privatisation and out-sourcing in partisan rather than efficiency terms: it's about moving economic assets and activities from the "them" column to the "us" column, so more businesses are beholden to your party and happy to donate.

Turns out the push to reduce "government failure" has produced reverse government failure. We start out trying to stop government intervention to correct market failure that's making things worse, but end up making them worse than they already were.

Then we wonder why the punters want no more "reform".

Our new comparative advantage: renewables

The old joke says the questions in economics exams don't change from year to year, but the answers do. Welcome to the economics of energy and climate change, which has changed a lot without many people noticing - including Malcolm Turnbull and his climate-change denying mates.

They've missed that the economics has shifted decisively in favour of renewable energy, as Professor Ross Garnaut​, of the University of Melbourne, pointed out at an energy summit in Adelaide last October.

Garnaut is chairman of Zen Energy, a supplier of solar and battery storage systems. But there aren't many economists who know more about the energy industry and climate change than Garnaut, who's conducted two federal inquiries into the subject.

He says that, since his second review in 2011, there have been four big changes in the cost of renewable energy relative to the cost of energy from coal or gas.

First, the cost of renewable energy generation and energy storage equipment has fallen "massively".

The modelling conducted for his inquiry assumed the cost of photovoltaic solar generation would fall by a few per cent a year. In practice, costs have fallen by about five-sixths since that assumption was made.

"Similarly large reductions have occurred in the cost of lithium ion batteries and related systems for storing energy," he says.

There have been less dramatic but substantial reductions in costs of equipment for electricity from wind and other renewables.

The cost reductions come from economies of scale in the hugely increased production by China and others, plus savings through "learning by doing". Advances in technology will keep prices falling after scale economies have been exhausted.

Second, there have been "transformational improvements" in battery storage technology, used at the level of the electricity grid, to ensure balance between supply and demand despite renewables generators' "intermittency​" (inability to operate when the sun's not shining or the wind's not blowing).

Third, there's been a dramatic reduction in the cost of borrowing the money needed to cover the capital cost of generation equipment.

Real interest rates on 10-year bonds are below or near zero in all developed countries, including Australia.

"These exceptionally low costs of capital are driven by fundamental changes in underlying economic conditions and are with us for a long time," Garnaut says.

Low interest rates reduce the cost of producing, storing and transporting renewable energy more than they reduce the cost of fossil-fuel energy because renewable costs are overwhelmingly capital (sun and wind cost nothing), whereas fossil fuel costs are mainly recurrent (digging more coal out of the ground).

Fourth, there's been a dramatic increase in the cost of gas - and thus gas-fired electricity.

Ten years ago Australia had the developed world's cheapest natural gas - about a third of prices in the US. Today, our prices are about three times higher than in the US.

Why? Because the development of a liquid natural gas export industry in Queensland has raised the gas prices paid in eastern Australia to "export parity" level - the much higher price producers could get by selling their gas to Japan or China (less the cost of liquefaction and freight).

It's worse than that. Because foreign investors were allowed to install far too much capacity for LNG exports - meaning none of them is likely to recover their cost of capital - they've been so desperate for throughput they've sometimes bid gas prices well above export parity.

Apart from making gas-fired power more expensive relative to renewables, this has implications for how we handle the transition from "base-load" coal-fired power (once you turn a generator on, it runs continuously) to intermittent solar and wind production.

It had been assumed that gas-fired power would bridge the gap because it was cheap, far less emissions-intensive than coal, and able to be turned on and off quickly and easily to counter the intermittency of renewables.

Now, however, without successive federal governments quite realising what they'd done, gas has been largely priced out of the electricity market, with various not-very-old gas-fired power stations close to being stranded assets.

What now? We thank our lucky stars the cost of energy storage is coming down and we get serious about storage - both local and at grid level - using batteries and such things as "pumped hydro storage" (when electricity production exceeds immediate needs, you use it to pump water up to a dam then, when production is inadequate, you let the water flow down through a hydro turbine to a lower dam).

In other words, the solution is to get innovative and agile. Who was it who said that?

Turnbull's party seem to be pro coal and anti renewables partly because they know we have a comparative advantage in coal.

We can produce it cheaply and we've still got loads in the ground. The rest of the world is turning away from coal and the environmental damage it does, but let's keep opening big new mines and pumping it out, even though this pushes the prices our existing producers get even lower.

If the banks are reluctant to finance new coal mines at this late stage, prop them up with government subsidies. Join the international moratorium on new mines? That would be unAustralian.

But get this: Garnaut says we also have a comparative advantage in the new world of renewables.

"Nowhere in the developed world are solar and wind resources together so abundant as in the west-facing coasts and peninsulas of southern Australia. South Australian resources are particularly rich...

"Play our cards right, and Australia's exceptionally rich endowment per person in renewable energy resources makes us a low-cost location for energy supply in a low-carbon world economy.

"That would make us the economically rational location within the developed world of a high proportion of energy-intensive processing and manufacturing activity.

"Play our cards right, and Australia is a superpower of the low-carbon world economy."

Mixed progress on reform of power prices

Do you think you're paying too much for electricity? Would you like to see an end to hefty annual price rises, maybe even a fall in prices that goes beyond the abolition of the carbon tax? Well, be patient. The econocrats are working on it.

It may surprise you that they've been in the process of reforming electricity prices for the best part of 20 years, and they're far from finished. They got part of the power system working well, had a bad slip with another bit, and the jury's still out on a third. But they're working away and are confident of success - eventually.

The national electricity market - covering all of Australia bar Western Australia and the Northern Territory - is actually a creation of our econocrats, their grand experiment in market competition.

Before this, we had separate, state-owned monopolies that charged us pretty much what they wanted to charge, particularly because our demand for power kept growing every year. The reformers' bright idea was to link up all the eastern and southern states and turn them into a market by making all the individual power stations compete to feed electricity into the national grid at the lowest prices possible.

Buying the power at the other end of the grid would be various electricity retailers, which would deal directly with households and business users. These, too, would be required to compete with each other to win our business, since we'd be free to buy our power from whichever retailer we chose.

Linking the power stations in the wholesale market with the retailers supplying power to you and me would be the high-voltage transmission and lower-voltage distribution network (the "poles and wires", as pollies keep calling it).

Since it would never be economic to build rival networks, this would have to stay as a monopoly. And being a monopoly, whether it was sold off or remained government-owned, the prices it charged the retailers - and they passed on to us - would need to be closely regulated to prevent rip-offs.

The reform of the first part of the system has worked really well. Competition between the electricity generators has been cut-throat, prices haven't changed much over the years and no power stations are making excessive profits.

But the cost of generating the electricity makes up only about 30 per cent of the retail prices we pay. The big problem has been that faulty rules have prompted the regulators of the network operators' charges to grant them excessive increases, to the point where "network charges" now explain about half of retail power prices.

It's five years of these big increases, much more than the carbon tax or the renewable energy target, that have caused retail prices to grow so fast. A big part of the problem is that, about four years ago, the demand for electricity, which had been growing every year for a century, stopped growing and started falling.
It fell mainly because of new laws requiring appliances to be more efficient in their use of power and because all the fuss Tony Abbott was making about the price of electricity prompted us to be more price-conscious and look for ways to reduce our usage.

The network operators began investing heavily to improve the capacity of the network to meet the ever-higher peak demand for power on hot summer afternoons when a growing number of us had airconditioners going full blast.

One small problem: the fall in annual demand for electricity meant the brief seasonal peak had stopped rising. For several years the industry refused to believe the downturn in demand from the network was more than a blip.

So we've expanded the capacity of the network beyond what we're likely to need for some time. But you and I are paying extra for this expansion and will continue paying until it's paid off.

The good news is the econocrats have finally woken up to the problem. Actually, they were woken up in 2012 by the fuss Julia Gillard made when she realised Abbott was framing her for price rises she didn't cause.

In 2012 the rules were changed to give the regulators greater power to limit increases in the network charges passed on to retailers. Such changes take far longer than you'd imagine to flow through, but from now on it seems likely the network component of retail electricity bills will stay fairly steady in dollar terms.

The econocrats have proposed a further reform which, when it takes effect, will require the networks to bill retailers according to the time of day and time of year when you and I use electricity. With the spread of "smart meters" - which show the precise times when each household uses its electricity - we'll be charged according to our time of use, with those of us who show restraint during peak periods paying less, and those who don't paying more. This should produce a lasting solution to the (expensive) problem of ever-rising peak demand on hot afternoons.

That leaves the question of the effectiveness of competition between the growing number of electricity retailers, big and small. Here the jury is still out. Much depends on how smart we are in finding the retailer offering the best deal - on which quest I offer some tips in my little online video spiel.

Modellers bamboozle over cost of renewable energy

There's a lot of public support for the renewable energy target, which requires electricity retailers to get 20 per cent of their power from renewable sources by 2020. But now the country's being run by climate change "sceptics", let's get with the program. Forget the threat of climate change, stop worrying about your grandchildren and focus on what matters most: what this do-gooder scheme is doing to your cost of living.

Although before the election Tony Abbott professed support for the target, since the election he has instituted an expert review of it, headed by businessman Dick Warburton, former chairman of Caltex and prominent "sceptic".

The review commissioned a leading firm of economic consultants, ACIL Allen, to undertake modelling on the future effects of the target.

The preliminary report found that, between 2015 and 2020, the target would increase the average household electricity bill by $54 a year - a tad over $1 a week. This five-year average, however, conceals the estimation that the cost of the scheme will fall as each year passes.

So by 2020 itself, the increase will have reduced to just $7 a year. By the end of another 10 years, in 2030, the scheme is estimated to be actually reducing average household electricity bills by $91 a year, or $1.75 a week.

It's common sense that requiring electricity retailers to buy a certain proportion of their power from more expensive renewable sources - mainly wind power, but also solar - would add to the cost of their power, with the extra cost being passed on to consumers.

So why has ACIL Allen's modelling concluded the target will add to the price of electricity initially, but eventually subtract from it? The short answer is because electricity pricing is a complicated business.

It turns out that adding to the supply of renewable energy available reduces the wholesale price of electricity. This is because the price being paid for energy being put into the national electricity grid by particular generators varies minute by minute according to the balance of supply and demand.

In the middle of the night, when little power is being used, the wholesale price is very low. But on a cold evening - or, more likely these days, a very hot afternoon - the wholesale price can be stratospheric.

The trick to renewable energy is that it tends to be available when the demand for electricity is high. Experience around the world confirms the Australian experience that renewable energy does a great job of reducing spikes in wholesale prices on very hot and very cold days.

Another part of it is that though it costs a lot to build wind and solar generators, once they're built there are few "variable" costs. Wind and sun are free; coal and gas aren't. So the renewable generators offer to supply power to the grid at very low prices and this lowers the prices the coal and gas generators are able to ask for.

But none of this changes the fact that the electricity retailers have to pay for the "renewable energy certificates" that the target scheme requires them to buy. These certificates reduce the capital cost of setting up the wind and solar generators whose operations then reduce the wholesale cost of power.

So it turns out the renewable energy target scheme has the effect of reducing the wholesale cost of electricity while also adding to the costs of the electricity retailers. ACIL Allen's modelling suggests that, for the next five years, the extra retail cost will exceed the saving in wholesale costs, but after that the saving will exceed the extra cost.

See what this means? The case for saying we must get rid of the renewable energy scheme because it's adding too much to the living costs of struggling families has collapsed.

But there's where the story takes a twist. Modelling of the future cost of the renewable energy target, published by an equally prominent firm of economic consultants, Deloitte, comes to opposite conclusions.

Deloitte's modelling accepts that the renewable energy scheme is reducing wholesale costs, and roughly confirms ACIL Allen's finding about the higher cost to household customers until 2020. But whereas ACIL Allen expects the scheme to start reducing household costs after that, Deloitte expects the cost to stay positive until 2030, causing household bills to be between $47 and $65 a year higher than if the scheme was scrapped.

Why have two leading economic consultants reached such opposing conclusions? Perhaps because Deloitte's modelling was commissioned by the Chamber of Commerce and Industry, the Business Council and the Minerals Council.

Deloitte doesn't conceal that its modelling is in reply to ACIL Allen's. Would it surprise you if the fossil fuel industry wanted to see the renewable energy target abolished and was alarmed to know that modelling commissioned by the review had demolished the argument that continuing the target would add to people's electricity bills? Now the review will be able to pick whichever modelling results it prefers.

How did Deloitte reach such different results? By feeding different assumptions into its model. It seems to have assumed the cost of wind farms won't fall over time (which it probably will), whereas the price of gas for gas-fired generators won't rise much (which it already has).

Regrettably, economic modelling has degenerated into a device for bamboozling the public.

CitySwitch Awards Night, December 3, 2012

No one ever promised moving to a green economy - an economy making minimal use of fossil fuels - would be easy, and so it has proved. Indeed, in recent years the challenge has look dauntingly tough. It’s too easy to leave it to other people - and other countries - to make the first move. It’s too easy to make excuses and even to deny there is a problem. Sometimes I think I’m glad I didn’t do much science at high school, so I’m not tempted to think I can explain to the scientists where they’re getting it all wrong.

Even so, I get the feeling we’re making more progress in recent days - and that we’ve been making more progress than popularly believed. Here in Australia, the breakthrough may have come with the introduction of the carbon tax on July 1 which - as many of us prophesied - wasn’t nearly as catastrophic as the public had been led to expect. The tax had been designed to be as least disruptive as possible, and so it has proved. With any luck, this anticlimax will see a turning of the tide in our resolve to get on with preparing for a green future. I read that the carbon tax is now more popular than Tony Abbott - though that’s not setting the bar very high. (46/44; -31 net approval)

In recent days we’ve seen a number of new authoritative reports - mainly from scientific authorities, but also from no more unexpected body than the World Bank - reminding us the climate change problem hasn’t been wished away. It’s still there and, if anything, getting more pressing. That’s hardly good news, but I get the feeling these reports have been getting more media attention than they would have done a year ago.

Another bit of encouraging news is that, soon after his comfortable re-election, President Obama reaffirmed his view that man-made emissions of greenhouse gases are contributing to global warming, and stated his intent to continue to take action to reduce greenhouse gas emissions. He said: “I am a firm believer that climate change is real, that it is impacted by human behaviour and carbon emissions,” noting that, “we have an obligation to future generations to do something about it.”

It’s true the US Senate has declined to agree to an emissions trading scheme, but though that may be the best way to progress the move to a green economy, it’s not the only way. And the Obama Administration has made great strides in instituting stringent new fuel efficiency standards for cars and light trucks. A related approach is greenhouse gas regulations issued by the US Environmental Protection Agency, which would limit emissions from certain power plants. And we shouldn’t forget that California and several other states are proceeding with trading schemes.

Similarly, many people don’t realise how much progress China is making in the development of renewable energy sources such as wind and, particularly, solar. When Julia Gillard’s recent white paper on the Asian century included projections for the growth in Chinese demand for our coal, Professor Ross Garnaut expressed the view that these seemed far too high because they underestimated the extent to which China would be relying on green energy sources.

And then, of course, there’s the little publicised fact that the Chinese government is proceeding with an emissions trading scheme on a trial basis in various provinces. Knowing the Chinese way of doing things, I won’t be surprised to see this develop into a nation-wide scheme.

The final bit of good news is the way so many of our own businesses are seizing the challenge and the opportunity to become front-runners in the shift to a green economy. This is occurring in various areas of business, but - as we’ve heard - in none more successfully than in the CitySwitch program. It’s great to see building managers and tenants combining with city councils to use energy more efficiently. They say there are no free lunches in the economy, and it’s true many lunches that look free aren’t really, but there are some, and when you can combine doing the right thing by the planet - and by our grandchildren - with saving on energy costs, this surely qualifies. If doing the right thing and saving on costs also brings competitive advantages - including by making more conscientious employees keener to work for such an enlightened employer - then all I can say is: you deserve it. I’m pleased to be here tonight to honour all the participants in the CitySwitch program as well as those receiving awards.
