The carrot, the stick and the map

The Can Do! attitude that harnessed the efforts of whole nations in an all-out war effort during WWII survives in the iconic figure of Rosie the Riveter. When men joined the armed forces, women filled their places in factories, transport, businesses and on farms. My Grandma Blanche saw out WWII as a transport driver for local military bases in the North of England, where her two daughters met and married improbably good looking airmen.

The US National Renewable Energy Laboratory (NREL) has given Can Do types a shot in the arm with the release of its report, Renewable Electricity Futures Study (RE Futures) which outlines how the US can convert its electricity system to 80% renewables by 2050.

The detailed report proves the nay-sayers wrong by demonstrating that current technology is sufficient and that intermittent sources like solar and wind are no obstacle.

The report is a massive work in four volumes and covers the subject comprehensively. It was funded by the U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy and is a collaboration with more than 110 contributors from 35 organizations including national laboratories, industry, universities, and non-governmental organizations.

I am very heartened to see responsible government agencies get on with the job of planning a pathway to the new low-carbon future. I'm afraid that Australia's Department of Resources, Energy and Tourism lacks the capacity, vision and leadership to produce useful work like this. They seem to be too much in the thrall of the coal and mining sectors.

A Can Do map is one of the three things needed for a fundamental shift in beliefs and practices. The other two requirements are: Awareness that the current system is unsustainable (the stick), and recognition of the benefits of change (the carrot).

The carrot, the stick and the pathway map are necessary preconditions for the transition from an ecosystem of denial to a culture of responsibility.

With a reason to act, confidence in the destination and an outline of what needs doing, millions of Rosies will roll up their sleeves and see that the job gets done.

Mother knows best

Anita Renfroe runs through some motherly advice in her Mom Song ...

share
make new friends
clean up after you
pay attention
be respectful
be careful
play fair
wait your turn
never take a dare
say thank you, please, excuse me
if all your friends jumped off a cliff would you jump too?

What happens when we grow up? Do we leave this advice behind along with our lego and paper dolls as kid stuff? Or do we take it as the basis for civil society?

The sheer weight of insults and lies thrown around in public discourse about policy response to climate change shows that many never heard their mother's call for attentive, respectful, fair dealings.

But worse than the insults and denigration, climate change deniers are embracing risky behaviour. They are ready to jump off a cliff and drag us with them.

Taking our mothers' advice, we clean up after ourselves, pay attention, act respectfully and refrain from jumping off cliffs. 

Mother Love, the ultimate renewable.

Dominique Browning of Moms Clean Air Force

Yin and yang of clean energy

Ma Xuelu, chief strategy officer for solar panel manufacturers Yingli, sketches a vision of the future of solar power.

We want solar to be the green energy that the common man can use. It’s not like oil, solar is a harmonious resource, a peaceful resource.

Ma Xuelu, Financial Times

In these words, I hear echoes of the ancient teachings of Taoism which promotes harmony or union with nature, virtue and self-development.

China has a long cultural history where patience is a core value, so I am interested to see that their forward planning gives prominence to clean energy. China plans to spend $27 bn in 2012 to promote energy conservation, emission reductions and renewable energy.  Their goal is to reduce emissions by 40-45% by 2020, compared with 2003 levels, and boost use of renewable energy to 15% of overall energy consumption.

Its deep history gives China a long term perspective. In contrast, many Western democracies have relatively new national identities and seem driven to make their mark quickly. Western cultures are impatient for results. When we encounter obstacles we sometimes want to crash through, or change course.

Li Junfeng, a senior policy official, brings a different perspective in this comment about difficulties encountered by fledgling solar and wind industries.

Our industries are still very young. A child will stumble as he walks, because he’s still young. But eventually he will grow up.

Li Junfeng, Financial Times

This reminds me that solar power has been described as the teddy bear of renewables because it is small and lovable. What will it be when it grows up? A 360kg grizzly?

This graphic from the Financial Times shows how China's fledgling wind industry compares with that of the USA (click to enlarge).

Waste not, want not

Waste not, want not.

Did you grow up with this homily? I seemed to hear it quite often when I grew up — mostly when I pushed vegetables around on my dinner plate. But then, I grew up in a time and place that is now foreign, even to me.

When I was five, I lived on a dairy farm and attended a rural one-teacher school. Electricity came from the diesel generator, water came from rainwater tanks, and the school even had a horse paddock for the couple of kids who rode horses to school.

That was post-WWII Australia — a foreign land compared with my current life in Sydney, one of the world's most liveable cities.

So, why am I thinking about "waste not, want not" when I could be thinking about Luke Nguyen's new restaurant?

It was triggered by this Eurostat data that ranks European countries on their use of renewable energy. One column of data shows the proportion of their energy that comes from 'Biomass and renewable wastes'. Here's a graph of the top countries.

Share of biomass/wastes in gross inland energy consumption, 2009

Latvia already gets 29% of its energy from biomass and renewable wastes!

These countries are so much better-prepared for the future than countries like Australia where we rely so heavily on fossil fuels for our energy. Less than 1% of our energy comes from biomass/renewable wastes.

It seems to be taking enormous effort for Australia to move to more sustainable energy, however our new carbon tax, starting 1 July, will make a difference. For example, it will give an incentive for major rubbish dumps to harvest their methane emissions and generate power, instead of letting the methane leak into the atmosphere where it contributes to global warming.

Another helpful measure is our State target to increase the proportion of ethanol in petrol. Ethanol in NSW is made as a byproduct from processing wheat into protein and starch. After these food elements are produced, ethanol is made, and finally the waste from ethanol production is turned into feed supplements for cattle. Waste not, want not. 

Nevertheless, it will take us decades to catch up with countries that already get more than 10% of their energy from biomass and renewable waste. Our efforts now will build a bridge to the new Clean Energy Economy that will appear when the Dinosaur Economy based on fossil fuels collapses.

Human societies are fast approaching the limits of some critical resources. The earth has only limited quantities of oil and gas. It is foolish to waste things that are in short supply.  Indeed, it is foolish to waste anything at all.

In a world of constrained resources, coming generations will re-learn what our grandparents knew. They will live again in a world where "waste not, want not" is the rule to live by.

Low hanging fruit

Non-carbon dioxide pollutants are the low hanging fruit of the climate fix. Carbon dioxide is the big baddy because it stays in the atmosphere for hundreds of years, but other greenhouse gases contribute 40% of the warming effect, and some of them are easy targets.

They include factory-made hydrofluorocarbons (HFCs), used as refrigerants and to make insulating foams; methane that leaks from landfills and oil and gas production, including fracking; and black carbon soot from dirty diesels, brick kilns, coke ovens, and wood and dung cooking fires still used by nearly half of the world.

See the blue band showing 10.2% bioenergy in this graph? Most (60%) of it is wood and dung used for cooking by the poorest of the poor.

IPCC: Total Primary Energy Supply by Fuel Type, 2008 (click to enlarge)

Because these non-CO2 climate pollutants wash out of the atmosphere in a matter of days to a decade and a half when you stop emitting them, almost all of the heat they are trapping disappears quickly, along with their impacts. Reducing or eliminating them would show quick results, and wouldn't that be inspiring!

Like many pollutants, these greenhouse gases cause other problems. Reducing black carbon, including from cooking fires, would save many millions of lives a year, mostly women and children. Reducing methane improves crop yields and protects forests.

HCFs can be elimintated using the Montreal Protocol which has already eliminated nearly 100 chemicals just like HFCs, and never fails to do its job. It could ensure that only HFCs with very low climate impact are manufactured. Phasing out HFCs is the single biggest climate prize available in the next few years.

On the international stage, governments are forming alliances to legislate for the removal of these harmful greenhouse gases. At the individual level, NGOs are running programs like The Himalayan Stove Project that help the world's poorest people replace smokey and polluting cooking methods with healthier alternatives. It's only with the help of the richer half of the world that the poorest 1 billion people can improve their own lives and reduce greenhouse emissions.

Non-carbon greenhouse gases are the low hanging fruit of climate fixes. Let's support these initiatives at the policy level and at the individual level.

A lump sum or a magic pudding?

I had a friend, Miranda, who spent her income as she earnt it. Her view was that she would get another packet of money next week to replace what she spent this week. Just like Norman Lindsay's Magic Pudding that simply re-grew when part of it was eaten, her money was continually replaced with a fresh supply.

I was concerned that she would go into retirement with no savings and I figured that paying rent on the age pension is no fun. So I suggested that instead of thinking about her income as a magic pudding that got replenished each week, she should think of it as a lifetime allowance that is doled out week by week. Across her lifetime, she would earn a limited amount of money, and as each week passed there was one less portion awaiting her.

After that, she started saving. When she retired, she didn't have enough to live on, but she was able to buy a small apartment in a regional town and lived a modest and contented life on the age pension.

It seems to me that Western consumer societies have been living like Miranda, as though natural resources would be magically renewed year after year. But that is not the case. Like Miranda's lifetime income, many of Earth's resources are large, but limited.

Towards the end of her working life Miranda had only a small portion of her earnings still to come. Similarly, some of Earth's resources have only a small portion left. For example, we have used most of the earth's oil resources, most of the arable land is already farmed and most fresh water resources are fully used.

With population due to expand by another 2 billion in coming decades, many of earth's resource budgets can only get tighter.

Fortunately, not all earth's resources are as limited as Miranda's lifetime earnings. Some resources renew endlesslessly in human timeframes. It's good to see countries beginning the transition to these magic pudding energy resources — sun, wind and geothermal.

By conserving our limited resources, we wisely give our children and grandchildren the opportunity to live fulfilling lives, instead of blindly devouring the lump sum of their inheritance.

Eureka! It's a bathtub budget!

When Archimedes noticed the water level in his bathtub go up, he had an "ah-ha" moment. The bathtub holds a limited amount of stuff whether it is water or humans. When you go over the limit, the bathtub overflows. His insight was to recognise that it doesn't matter whether it is water or a grubby human body, when you put too much in, the water spills over the edge.

Similarly, the atmosphere can hold a limited amount of greenhouse gases (GHGs) before climate systems go crazy. It doesn't matter who puts them there, when there's too much we get climate catastrophe — droughts, ocean acidification, rising sea levels, storms and floods.

To stop the water spilling onto the bathroom floor, you have to turn the tap off. Even a small drip will cause the bathtub to overflow eventually. It's the same with the atmosphere, we will have to stop GHG emissions altogether or the climate system will go crazy. Carbon sinks don't work like a bath drain because they developed over millennia to balance the amount of natural CO2 emissions and they can't cope with the extra emissions humans have been putting out from fossil fuels. They can't drain it out as fast as we're putting it in, so the water level has been inching higher every year.

How soon do we need to turn off the tap and reduce our GHG emissions to zero? That depends on how close the bathtub is to overflowing. Is it half-full, or lapping the rim?

The best scientific advice is that the size of the GHG tub is about 350 ppm of CO2-e gases. This is a lot higher than the pre-industrial level of 280 ppm when the GHG bathtub was nicely balanced.  For thousands of years GHGs dripped into the tub and the leaky plug (carbon sinks that absorbed carbon dioxide) let them out  at the same rate. 350 ppm is higher and it will have some climate impacts, but they are likely to be manageable.

Right now, measurements of 400 ppm CO2 are starting to come in. This means that the tub is already overflowing. We have no time to waste to move to zero emissions as quickly as possible.  If we don't, we are driving headlong into catastrophe which guarantees that we'll have a big clean up job to do.

All our policies should be directed towards this bathtub budget. But how do we calculate our share of the bathtub budget? For social justice to prevail the only fair measure is to allocate a carbon budget for each per person on the planet. Based on 7 billion people, this works out to be about 5 tonnes of CO2-e per year (c.f. Serbia or Argentina). When world population has grown to the projected 9 billion, then our per-person budget will be 3.9 tonnes of CO2-e per year (think of Jordan or Turkey).

This means that Australia has to move quick-smart from something like 28 tonnes per person (the highest among OECD countries) down to 5 tonnes per person, and then be prepared to shave off a bit more.

Targets like "5% lower in 10 years time" aren't going to stop the bathtub from overflowing any time soon.
