Waiting For Garnaut, No More

The long awaited Garnaut report (pdf) is out at last, prompting an explosion of media analysis.

This post is a roundup of selected articles - I encourage you all to share your thoughts in the comments.


SMH - Climate crisis 'diabolical'

An effective response to climate change must take shape and be in place in the next few years, the federal government's top climate change adviser says. Professor Ross Garnaut 600-page draft report on climate change, of which the make-up of an emissions trading scheme (ETS) is a major focus, was released today.

Speaking at the report's launch in Canberra, Prof Garnaut said climate change was a "diabolical'' policy problem. "While an effective response to the challenge would play out over the many decades, it must take shape and be in place over the next few years,'' he said. "Without early and strong action, some time before 2020 we will realise we have indelibly surrendered to forces that have moved beyond our control.''

Prof Garnaut said climate change was the hardest policy problem in living memory. "Climate change presents a new kind of challenge,'' he said. "It is uncertain in its form and extent, rather than drawn in clear lines. It is insidious, rather than directly confrontational. It is long term, rather than immediate in both its impacts and its remedies. Remedies will require global co-operation of unprecedented complexity and dimension".

"We have much to contribute and much to lose as we face the diabolical policy challenge of climate change,'' Prof Garnaut said. "The most inappropriate response would be to delude ourselves, taking small actions that create an appearance of action, but which do not solve the problem. Such an approach would risk the integrity of our market economy and political processes to no good effect."

The report says Australia would be deluding itself if it used scientific uncertainties as a cause for delay. "Delaying now will eliminate attractive lower-cost options. To delay is to deliberately choose to avoid effective steps to reduce the risks of climate change to acceptable levels."

The draft report recommends the emissions trading scheme issues permits for greenhouse gas emissions up to limits and release them in line with the scheme's carbon reduction trajectories. Trade will move permits to entities for whom they have most value.

The draft report says while there are advantages in moving directly to an unconstrained scheme, "2010-12 could be a transition period. If there were a transition period, the Kyoto Protocol would define Australia's emissions reduction trajectory and permits would be sold at a low fixed price. These years would be used to pursue effective international sectoral agreements, en route to a global agreement."

Unlimited hoarding of permits will be allowed and an independent regulator would be able to lend permits within five-year periods.

The Australian - Garnaut climate change report rejects emissions trade delay

Professor Garnaut has released his landmark Garnaut climate change report today, suggesting tax cuts and welfare reform to compensate business and families for the impact of the new scheme. However, he has conceded that a second-best solution might be to put a fixed price on permits in the early years to reduce volatile and unstable prices.

He rejected suggestions of putting off an emissions trading scheme until 2012. ``I think the critical question is, would it actually help to delay?'' he told the National Press Club today.

On the issue of superannuation and whether people should be compensated for the deterioration in their funds, Professor Garnaut said there were safety nets available to prevent a financial fallout. ``If the Government is disciplined in selling permits, it will have a substantial amount of revenue,” he said. ``We've suggested in the report that half that revenue should be returned to households in one way or another. ``It could be through tax cuts, it could be through social security adjustments.''

Earlier today, the Prime Minister said the Government would not accept all the recommendations in the report. “There is no dispute about the science - that it is happening,” he said. “The practical question becomes one of, first of all, what are the economic costs of not acting as opposed to the economic costs of acting.

ABC - Govt urged to act swiftly on Garnaut findings

Environmental and industry groups have urged the Federal Government to act on climate change findings in a draft report presented by Professor Ross Garnaut. Mr Garnaut called for an emissions trading scheme for Australia without delay as the best of the possible options for cutting greenhouse gas output.

Crikey - Keane: Garnaut paints disturbing future for Australia

Ross Garnaut’s draft report paints a disturbing picture of the potentially immense costs of climate change for Australia, and the difficulties of getting the right policy response. Describing climate change in his Press Club speech today as a "diabolical policy problem" that is "uncertain", "insidious", "long-term in both effects and solutions" and requires international action, Garnaut suggests there is a need for early, strong mitigation before the problem gets beyond human control.

However, the report stresses that Australia, even if it is exposed to climate change more than any other developer country, has never been better placed to take action, given the continuing resources boom and the benefits of the economic reforms of the 1980s – indeed, Garnaut stresses, there are potential opportunities for Australian industry.

An emissions trading scheme is obviously the centrepiece of Garnaut’s proposed response, but the report also flags the need to undertake massive investment in low emissions technologies – up to $3b a year, improve the capacity of network infrastructure (such as electricity transmission grids) to complement carbon mitigation activities, and address information problems to enable Australians to improve the efficiency of their energy usage.

Garnaut’s ETS is a hardline model that will displease energy-intensive sectors. He excludes agriculture until measurement and information problems can be sorted out, and also omits waste and forestry from the initial stages of the scheme. There may be some criticism of this from farming groups, who have argued that agriculture should be included and awarded free permits to cover their past cessation of land clearing, which has been the sole reason Australia has met its Kyoto targets.

Everything else, including transport and energy production, would be included from the get-go.

The Australian - No mercy for dirty power, says Garnaut's climate report

REGIONS hardest hit by the new emissions trading regime would win government handouts and industries investing in clean power would be rewarded, but the landmark Garnaut report on climate change rules out compensating coal-fired power stations.

Business Spectator - KGB INTERROGATION: Wayne Swan

AK: The hot issue at the moment is emissions trading. The Garnaut Review comes out today and the government’s Green Paper not long after, so does the government remain committed to an emissions trading scheme as opposed to a carbon tax?

WS: The government is committed to an emissions trading scheme. It’s what the Green Paper is about. It will look at all of the issues involved for the construction of an emissions trading scheme. We’ve got a period of consultation through the second half of the year following which the government will take its decisions after a lot of consultation with both households and the business community and we are committed to, as we committed during the election campaign to the commencement of such a scheme in 2010.

Crikey - Climate Institute: All eyes on the government now

If the Government responds with the right policies, today, the fourth of July, would mark an important step towards carbon independence day. Professor Garnaut’s report adds urgency for Australia’s journey away from the fatal shores of our high carbon economy.

Arriving at a low carbon economy will require policies that create powerful low carbon investment engines to grow the economy and jobs. The Government’s industry focus needs to be on investment and support, not compensation, to assist the transition of our economy to using clean energy and low carbon technologies.

Any assistance for generators or emissions intensive industries genuinely impacted by emissions trading needs to be connected to supporting a transition to clean energy and low carbon outcomes. We broadly support the draft report’s comments in this regard. Any suggestion to put an ETS on training wheels would require ramping up other measures like clean energy incentives, energy efficiency reforms and public transport investments.

Business Spectator - Garnaut's theorem: E=M-C

The climate change debate is often portrayed as a stark choice between two extremes. Do we try to save the economy or do we try to save the environment? Many in established industries argue vociferously that you need to protect the former to save the latter, or that if we act to protect our environment then we might end up killing the economy.

Ross Garnaut, in his much awaited draft report, seeks to turn that argument on its head: Australia has much to lose from even the mildest impacts of climate change. If we want to save our economy, then we need to save our environment first. ...

It will be interesting to see what the most vocal industry groups have to say in response. So far, we have seen little more than the expression of vested interests.

For instance, Brad Page, the CEO of the Energy Supply Association of Australia, was on the radio this morning claiming that energy generators needed to be protected from a scheme because they were the only ones in a position to invest in new energy technology. Pure hogwash. The flow into new and renewable technologies in places like California, where they have been smart enough to encourage such investment, is just extraordinary. In Australia, the renewable energy target attracted nearly $12 billion of investment before grinding to a halt when the Howard Government acceded to lobbying from the likes of the ESAA and decided to can the target.

Crikey - Milne: Garnaut can’t see the forest for the trees

As foreshadowed for some time, the Professor is strongly calling for auctioning of all permits under the scheme. This is excellent news which, if adopted, will avoid one of the largest problems of the EU scheme, when sectoral lobbying and deliberate gaming of the market led to horrible market distortions in the first years thanks to the decision to grandfather permits.

Another issue where we are in complete agreement is on coverage of the scheme. The immediate inclusion of all energy, industrial processes, fugitive emissions and transport, with forestry and waste being brought in as soon as practicable and agriculture dependent on appropriate measurement capability, is exactly what we have been advocating.

It is particularly pleasing to see support for complementary measures such as feed-in laws and MRETs to bring on line the renewable energy technologies that will power our future, as well as the rejection of nuclear power.

However, Garnaut clearly has a blind spot on coal. He has been taken in by “fool’s coal” and believes that geosequestration will be the saviour of the Hunter and Latrobe Valleys. If he truly understood the urgency of climate change, Professor Garnaut would not be punting on a technology which is at least a decade from proving itself, if it ever can, and can never be one of the truly zero emissions energy sources we need in order to achieve fast and deep cuts in emissions in coming years. But, like the politicians, he seems incapable of envisioning Australia beyond coal.

Great G-Day collection Gav!

Penny Wong was very cagey tonight about what exactly will be implemented, though. There'll be yet another delay until the "Green Paper" reveals the Government's opinions.

I also find it bizarre that until "everyone else" does, we won't be adding any Carbon Price to our export coal. Given that we're the world's 2nd largest exporter...
(after Indonesia, surprisingly enough http://www.abareconomics.com/interactive/ac_sept07/htm/coal.htm ) ...and that our exports are nearly double our domestic consumption, it seems that we're only about 1/3 serious on cutting atmospheric Carbon.

Right. Which is just an example of the fact that the only sensible approach is to impose the carbon cost (tax or trade) as it comes out of the ground. So how much increase in the price of carbon do you need to get people acting on efficiency, and switching to alternatives, and even going broke? The answer is that we've already had that much and more because of peak oil, and gas and coal have followed oil up. The world economy is in free fall at the moment because of this. However the oil price has overshot (because demand destruction takes longer than the time frame in which this oil shock has hit). So the oil price will soon come back down temporarily [wait for the ignorant to say the bubble has burst]. When you look at this point it now becomes obvious how to combine peak oil response with carbon mitigation: Use a carbon tax to put a floor under the price of fossil fuel, and keeping moving the floor up. This means that the incentives for switching and efficiency are maintained instead of yoyoing with the oil price. The money raised should be used to build the best possible non-fossil fuel energy infrastructure, whatever that is.

I agree. Australia's coal exports tend to make a mockery of supposedly leading international efforts at carbon cuts. On rubbery offsets the other source of weakness Garnaut doesn't say too much but it evidently won't include tree planting.

If we included coal and LNG exports in a cap our customers would have to cut back as well. Think of it as an extended family on a carbon diet. If they don't play ball they get no uranium. Let them get the coal from the US or Indonesia but make a mental note 'not helping'.

We'll also need to ensure the hand back of auction revenue will actually work ie don't give $500m for carbon capture and $5m for smart meters.

Boof,
I see two problems with carbon taxes for exports; one, we want to encourage LNG consumption in Asia instead of coal, and secondly if we carbon tax coal exports does that mean we are responsible for the CO2 generated when this is burned? Should we pay a carbon tax on the CO2 generated in manufactured imports, or other products, for example timber? A crucial part of the world system is that CO2 is measured where CO2 released or captured.
It would make sense to tax CO2 generated in manufactured imports from countries if they refuse to sign up to future agreements, but difficult to measure.

Carbon charges embodied in FF exports should make LNG cheaper than coal per unit of energy, but I'd have to check how much it changes the existing price. The principle of the seller being responsible for the user is already widespread eg selling alcohol to minors. It works of course only if all sellers co-operate which is why the local aluminium industry is pleading for help.

It would be an administrative nightmare to impose precise carbon charges on imports. If there was an agreed notion on which countries were 'doing the right thing' they could trade between themselves without customs adjustments. If Australia was greenhouse compliant and China wasn't we could slap a punitive tariff on their goods. It would have to be an arbitrary amount say 20% or $100 on a fridge until they joined the good guys club.

I think we should start with blunt instruments then fine tune eg
-export coal is in the cap
-aluminium exporters get special help
-tying yellowcake sales to carbon cuts
-arbitrary carbon import tariffs.
It would be a schemozzle for years but I don't see otherwise how we can get China and India to decarbonise. Yes it is inequitable that we're starting from a higher per-capita emissions baseline.

I agree it's time for Australia to start behaving like "Export Land". The coal, uranium and LNG will be worth a hell of a lot more in the future if we don't sell it now.

Hmmm, but we may need some nuclear munitions to defend it all from the angry customers... How soon can you get your breeder reactor down there in Tassie fired up, Boof?
;-)

Since 98% of the Derwent flows out to sea (unlike the Murray) it could do some cooling while it's at it. The warmer water will help the already toxic fish cope with the muck from factories. Tassie is no longer 'clean and green' since it became utterly coal dependent via Basslink.

With a 20% MRET windpower along the roaring forties should grow substantially. Tas Hydro doesn't appear to be interested in pumped storage so some of that green electricity could be sent back to the mainland. The wind potential should at least max the HVDC cable outflow with 500 MW.

I favour baseload nuclear power stations at godforsaken places like Whyalla and Broken Hill on the mainland. The water and transmission problems are solvable. Let's give Gav's favoured geothermal and concentrating solar 5 years to show they can produce the amounts of cheap reliable power the system wants. Then go for proven technology.

Wind, solar, tidal and biogas are already proven (as is geothermal for that matter - if you want to call it "unproven" you need to specifically refer to Hot Rock geothermal, not traditional surface geothermal and low temp geothermal - both of which have been around for a long time - and provide a lot of New Zealand's power, for example).

We should be encouraging a lot of experimentation with wave power, HFR geothermal power and subsurface tidal / ocean current power

In the meantime we can get to work building up large scale wind and solar power plants and making sure we generate biogas from all our waste streams - and making the grid smarter and more dynamic, abandoning this obsolete "baseload" mentality that some remain mired in.

Eventually we'll get to 100% clean energy and leave the old model of dirty power generation behind.

I reckon 20-40% tops.

reckon, n.

# think: expect, believe, or suppose; "I imagine she earned a lot of money with her new novel"; "I thought to find her in a bad state"; "he didn't ...
# calculate: judge to be probable, make a mathematical calculation or computation
# see: deem to be; "She views this quite differently from me"; "I consider her to be shallow"; "I don't see the situation quite as negatively as you do"
# count: have faith or confidence in; "you can count on me to help you any time"; "Look to your friends for support"; "You can bet on that!"; "Depend on your family in times of crisis"
# take account of; "You have to reckon with our opponents"; "Count on the monsoon"

Which is it?

Do you believe "20-40%" tops?
Do you calculate it? If so, what is the basis of your calculation?
Do you see it as or count on it being 20-40% tops?
Are you making plans taking account of it as being 20-40% tops?

Because honestly, most of us will only be interested in the calculation. Your beliefs, imaginings and plans are very important for you and your family, but not very important for us.

These are fair questions and I see the start of a long thread. I'll break it down;

need for baseload - people who actually run power grids say about 40% of the total needs to be constant output ie to run hospitals and aluminium smelters

get real about wavepower and hot rocks - I'm sure there's a dentist's waiting room somewhere with a Popular Mechanics from 1975 that says these are the next big thing. How come it's taking so long?

the EROEI cliff - (see Euan Mearns articles) what distinguishes us from the Neolithic is that we need system averaged energy returns >10 or so. That's intermittent power with major backup.

there's not enough spare cash - we can't easily change from power that's 5-10c per kwh to power that costs 30-50c due to high financing costs. Another way of looking at it is that if future energy has a payback of 8 years we need all the spare energy from the next 8 years just to replicate the current output.

does the Easter Bunny exist? - I'm not saying yes or no but I want to see the evidence. What large countries have 50% or more renewables without unique factors?

This confrontation is long overdue and there's plenty more ammo. I suggest the next few years is put-up or shut-up time for the dreamers.

Boof - you are close to trolling now, making your usual collection of assertions without backing them up with any references.

Show me articles from the 1970's predicting imminent wave power or HDR power generation. From Popular Mechanics or any other source. Just one.

Both wind and CSP have EROEI way over 10, so there is no EROEI cliff to worry about if we get cracking building enough supply.

Your obsession with "baseload" I find strange. Most of our "base" load in Australia is a function of offering very cheap late night power to these smelters - because all this excess fixed capacity existed.

You are relying on circular logic. If large coal fired power stations didn't need to generate a minimum level, then we wouldn't have this demand in the first place.

Supply is variable, so is demand. That is just how it is, in spite of your apparent need for some sort of fixed baseline. As the gird gets smart and we utilise more clean and obviously intermittent power sources, demand will be managed to meet supply.

Its not that hard - the idea of markets has been around for a long time now.

Okay, so you believe and count on it. You didn't calculate it, you've no basis for your ideas except one or two private conversations and some made-up stuff - your imagined PM article, for example.

That's okay, you can believe what you want. But if you're going to tell others what to believe, then we need to have... well, you know: facts.

Ideas based on casual chats and made-up stuff we can manage by ourselves, we don't need your help ;)

I disagree with Boof on nuclear power but I also agree that 100% grid electricity from renewables is a big ask. In the case of wind, csp, PV, tidal, wave, ocean currents, geothermal and hot rocks, all of them have some level of proven ability to generate electricity. What they have not yet proven is the ability to run a modern industrial economy (any OECD one would do) and scale appropriately to allow economic growth and BAU to continue.

In both the arguments there seems to be an assumption that BAU is both possible and desirable, albeit with a bit of refashioning in the image of Boof or Gav.

Gav's renewables and Boof's nuclear won't produce liquid fuels, the recent price rises of which have created the start of a tsunami of political momentum which threatens to wipe the climate change concerns completely off the landscape.

Liquid fuels are mostly used for transport.

Transport can mostly run on electricity (planes being the main exception).

Therefore you can replace liquid fuels with electricity.

Electricity can be provided by renewables and/or nuclear.

The amount of energy available from renewables is more than 10,000 times our current energy consumption.

Therefore you could replace almost all our liquid fuels needs with renewables (nuclear advocates would make a similar argument about nuclear power, though you can argue about how long this could be sustained, whereas renewables last "forever", or thereabouts).

Change is possible, I don't see why people focus on one type of change (peak oil production) and refuse to accept many other changes aren't possible at the same time...

Whether or not "BAU" is desirable is another matter - there are other issues to deal with - but each of those is an additional discussion.

Shipping is the other exception. We have had electric transport in some areas of the world for a little over 100 years. The knowledge of electricity and its generation, distribution, control and application has expanded vastly since the 1950's and the advent of the electronic age. The advancements that are happening today are minutely incremental and are more focused on the nano, compared with the leaps and bounds that took place in early twentieth century. The electric vehicles that are yet to appear in Australia, all look like lightweights and are trying to mimic what a petrol/diesel can do but don't seem to making any great market penetration.

Electric rail passenger transport only makes economic sense in densley populated urban areas, or between major metropoli. Freight rail to and from factories is possible only once the factory reaches a certain size. Retail deliveries have a similar problem. But perhaps the biggest industry that cannot be electrified very easily is agriculture.

The transporting of grain, livestock, fodder and produce from farms is heavily reliant on trucks which are not easily replaced. In a post peak oil scenario where diesel is in short supply, it is questionable as to the survivability of many agricultural industries on the transport implications alone, let alone what is used on farm. It doesn't matter if there is oodles of electricity from any source available if it cannot be practically applied to a traction motor that is hauling a load. When it costs $20-25M just to put in a rail siding, what do think it will cost to run an electrified line past the door of every farm in the country?

The relentless assumption that we can just order up electric transport for everyone and then power it with renewables (or nuclear) is a simplistic answer to a complex set of questions.

The questions we need to be asking oursleves is what is essential transport and what can we do without; how do we redesign cities and towns so that people don't need to use mechanised transport as much as they currently do; if people are staying put, how do they get fed, clothed, housed and all the other essential inputs for life; what are the people going to do to keep themselves occupied, and what implications for transport does that have? etc etc ad infinitum.

If we can come up with low energy solutions to these questions, like Kiashus example of the 1 Tonne Carbon Lifestyle, then we may be able to simply retire many of the FF technolgies we currently use and either not have to replace them with anything or give zero emission technolgy a much lower total demand that they need to meet.

Its funny how differently people look at rates of change.

I see both the electric grid and vehicle transport poised for large transformation - and its already beginning in some places.

What is happening in Australia today is irrelevant - we don't lead in technological change - we follow.

You need to watch what is happening in California, Germany and Japan - that is where technological innovation actually happens.

Electric cars and smart grids are both hot areas now for venture capital investment. The majors are hurrying to catch up in the car industry and various cities are already starting to roll out smart grid programs. We'll see both trends manifesting themselves here within a decade.

As for farm machinery, if it can be run by a diesel engine, it can be run by an electric engine - I don't see why you think this change impossible.

Even if it was, we could use biofuels (ethanol, biodiesel or CNG from biogas) for agriculture - no big deal.

Low energy solutions are good, but they aren't the only way. As fuel prices rise, we'll see people, organisations and communities adjusting in different ways depending on their individual circumstances.

The only question about the 100% target is when - hopefully it will be in 40 years time - worst case 150 years...

Boof and Gav,
The question you are discussing whether we can replace 20-40% or 100% of FF use with renewable energy sources is the critical question for Australia. Presently we use about 50% of energy for electricity production,and of this 55%is from coal, 25% from NG and the balance mainly hydro(18%) with a small amount of wind.
Phasing out all coal generation power with wind ( and later solar) could be possible using NG and hydro to cover peak demand. Replacing most NG would require additional pumped storage and transmission lines in the east coast. Cost is the issue, but electricity is very low cost and "clean coal" is going to take time and is expensive. NG and oil have risen x4 in price.
Th go beyond 40-50% renewable fuels, will require converting car and rail to electric. This is going to happen for passenger vehicles over next 20 years. Converting trucks to battery power is not possible with current technology, but may be able to use re-recyclable once use chemical batteries(Zn/O2, Al?). Air transport may have to use bio-fuels. Sea transport is very efficient at low speeds.
The remaining 25% of FF(not oil) are used for cement, steel, chemicals; these may be very difficult to replace BUT not impossible over longer time periods with modest technical improvements.
I would conclude then that 75% of FF use could be relatively easily be replaced by wind, solar, geothermal, wave and tides and would enable BAU( sort of). Nuclear would help base-load, but not essential for Australia or countries with good hydro for pumped storage.
I would agree with Boof that in 1970's lots of Popular Mechanics stories of wave and geothermal, but also jet turbine and nuclear cars, rocket ship travel around world, supersonic aircraft. All possible now but just too expensive or too many problems of safety(supersonic air travel).

I agree that we need to expand the grid and pumped storage (and other forms of energy storage - ideally the CSP plants would have storage built in, and new wind plants would have some, perhaps modest, amount of additional storage as well).

We also need to make the grid smarter and to manage demand better - which means variable pricing and the ability for consumers to 'program" their energy consumption based on price, which would automatically level out a lot of load peaks (thus further reducing the need for Nat Gas plants).

I don't want to make this pick on Boof day... but...

Since 98% of the Derwent flows out to sea (unlike the Murray) it could do some cooling while it's at it. The warmer water will help the already toxic fish cope with the muck from factories.

I hear statements like this quite often. Implicit in this statement is the idea that river water flowing to the sea is wasted... if "we" don't use it. Now it might be true that the sediments downstream of the zinc smelter are stuffed, but is it really necessary to then reason that since that bit is stuffed lets stuff it some more by heating it up as well? Thermal pollution is not as benign as you seem to think.

River water carries with it the nutrients that make estuaries and river outfalls productive fisheries areas... especially around Tassie.

the amounts of cheap reliable power the system wants

Do we make "the system" or has "the system" made us?
Aren't we now in the process (ie Garnaut) of redefining what "the system" needs, rather than wants?

No surprises in Garnaut.What else could be expected from an economist and that is why he was selected by Mandarin KRudd.
I suppose I am simple minded(or just plain simple) but all this blather about carbon trading/carbon capture looks like pissing into the wind and an excuse to do sweet FA about the real problems.
The simple fact is we have to reduce our oil consumption,drasticly reduce our coal consuption and start building sustainable alternatives and do it ASAP.And that is just the beginning.

Below,some food for thought.
From "The Unconcious Civilization" by John Ralston Saul-
"Considering how much effort went into building this society,we have nevertheless engaged in an unconscious process which can best be described as slow,masochistic suicide.And suicide,except in very rare cases,is the product of an inability to see ourselves in the context of our reality.
Death appears to be the door of salvation from our illusions". (1995)

Thirra, by "start building sustainable alternatives" do you mean restructuring our cities and towns and general liveing arrangements to crteate a simpler and less enrgy demanding lifestyles or do you also subscribe to the various techno energy alternqtives like wind, soalr et al?

I might note that I don't advocate clean energy alone as the solution to our problems - changing our demand levels is also important (optimal) - which means redesigning urban areas, individual buildings, transport systems and our whole way of manufacturing goods...

Termoil,I subscribe to many sustainable alternatives,including downsizeing,localizeing,etc etc which roughly translate into lifestyle changes.
However,I also believe that there are many technologies which will assist us in making the transition to a sustainable system.These need to be applied as soon as we can otherwise there will be a catastrophic collapse.I'm deliberately leaving out the climate change problem as this is a real wild card.A lot of climate change is already built in but the sooner we can arrest the increase in greenhouse gases the better.Rapidly reducing our fossil fuel use will help that.

I liken our current situation to a square in which there are pieces of a jigsaw puzzle which we are trying to put together into some sort of coherant whole.The problem is that some of the pieces just don't fit and no amount of rearranging and even cribbing by sawing bits off is going to get the puzzle solved.
We really need to get into the habit of thinking outside the square because that is where the solution to the puzzle is located.
