Avatars walking through the virtual world of Second Life are leaving very real footprints, in our world. What I’m talking about here are carbon footprints, a familiar topic for this blog. The issue of the environmental impact of avatars (virtual characters which represent users online) was first raised in blogs a few years back, where an argument over the details has raged ever since.

These avatars are not as innocuous as you may think. The catchy statement doing the rounds is that, the average Second Life avatar is responsible for roughly the same amount of carbon emissions as a resident of Brazil, amounting to over one ton of CO2 per year. This very real power use attributed to online characters is due to the banks of servers dedicated to ensuring their existence, though debate surrounds how true theses figures are.

Whether or not these calculations are accurate is not the real point. It is instead a reminder to those of us forgetting the huge power consumption caused by our internet usage, and the banks of servers dedicated to our online existence. This is likely to increase rapidly as web-based applications, services and data storage are becoming the norm, all of which rely upon remote servers.

Think about your Facebook and email accounts, chewing through powere regardless of whether you’re online or not. Some web hosting companies are now attempting to address the issue, offering green powered web hosting.

Avatars to the rescue!?

These virtual beings whose footprints ignited the debate, may now lend us a hand. It is reported that businesses are snapping up real estate in Second Life to act as private meeting spaces for their employees (see the story here). This equates to savings in aviation travel costs, and of course, this equates to real savings in carbon emissions.

Flight Emission Calculators

You’re probably aware of the huge impact of air travel on your carbon footprint. For something most of us don’t spend much of our time doing, flights are responsible for a surprisingly large fraction of our annual carbon emissions.

For myself, I’ve calculated that flights account for roughly one third of my total annual carbon emissions, a quite startling fact given that I’ll only take a handful of domestic flights this year!

So how do you calculate the emissions which will be emitted on your next holiday or business trip? A number of online calculators now exist.

A brief review of a few follows;

  • Carbon Planet – Enter airport names, click, voila. The airport database is comprehensive. CO2 equivalent are reported.
  • Terrapass – Very similar to Carbon Planet. Metric conversion sadly unavailable. Gives a comparison to parallel trips by train or car.
  • Cheap Parking.com – This is a great little visual tool which lets you click destinations on a map powered by Google Earth. The coverage is poor outside of Europe and the US, though major Australian airports are covered.
  • CO2 Australia Group – Comprehensive coverage of Australian local airports. You can ‘add’ flights such that you can quickly compare flights of calculate a whole bunch at once (I used this to calculated my own flight emissions for this year).
  • Choose Climate – Not as ‘pretty’ as the others but much more interesting. Provides a clickable map though airports aren’t marked. If you’re interested in actually understanding the calculations, and the difference between CO2 and CO2 Equivalent, have a play with this tool.

Now here is a great way to get fit, eat healthy and save energy. Of course it onlt helps if you use the exercise to replace other exercise you would have done purely for exercise. You would need to consider the impacts of the large bike if purely for blending as well.

This is what makes talking about carbon impacts or footprints so daunting. It’s not just the elctricty you would use to run the blender, but the whole life cycle of the machine. we all need to start thinking more deeply about the life things have before they get to us, and that after us.

Virgin Galactic Unveils Mothership

Sir Richard Branson and Virgin Galactic have celebrated the unveiling of their new ‘mothership’. The aircraft named White Knight Two has been designed to carry and then launch SpaceShip Two and it’s cargo of private passengers into space. Would-be astronauts can fork out US$200,000 for the view of a lifetime and to escape the burden of Earth’s gravitation pull.

The announcement comes amidst tough times for the aviation industry. Fuel prices have cut deep into airline profits and as the reality of climate change becomes more apparent, the industry is increasingly finding itself lumped with a share of the blame.

Branson sees his bold space project as a potential saviour.

While, as you know, I believe that aviation has to get much more carbon efficient than it is today, it is important that people begin to realize that seemingly benign industries such as IT have in fact overtaken aviation in terms of their CO2 output and seeing WhiteKnightTwo in reality sends the message that aerospace really can become much more efficient than other forms of transport or indeed entire other industries and at the same time, help them improve their environmental footprint

Can White Knight Two be the Green Knight too?

What do you think?

Rice grower goes against the grain

If you believe what you hear in the news, NSW rice farmers are queuing up to make the move up north. The reason? To grow rice on the state’s North Coast which enjoys natural rainfall… who’d have thunk it?

The excitement was prompted by a single farmer’s successful entry into the rice growing world. Gary Woolley, now the region’s only rice grower has demonstrated the potential for a rice crop in the area.

Mr Woolley’s impressive yields are the envy of irrigation-dependent rice growers from the state’s south and for many, have prompted exit plans from the parched Riverina area. It seems that irrigation’s promise of increased yields has lost it’s allure, especially as many irrigators received no water allocation this season.

Such a northward move may provide a sustainable rice industry, given the bleak outlook for the Murray Darling system. An ‘out’ for irrigators will free up water allocations, but to what end? Hard decisions still need to be made to ensure a sustainable future for the region.

Now this is fascinating. You will probably never get the chance to see this happening. A giant squid caught by fishers off Victoria is dissected in a public forum. Rarely caught whole and hardly ever seen in captivity this is a great video for anyone with a interest in Australia’s natural history.

With expert commentary from Dr Mark Norman, world-renowned squid expert and Deputy Head of Science (Marine Zoology), Museum Victoria.

They even talk about squid that can fly. Now that is amazing.

Al Gore’s repowering America speech

Solar PV Dish Power Station 6 Alice Springs NT
Climate change activist Al Gore gave a speech at We calling for the US to not just reduce it’s dependence on oil – but to stop using oil for energy all together.

Now that’s a challenge.

Yet when we look at all three of these seemingly intractable challenges at the same time, we can see the common thread running through them, deeply ironic in its simplicity: our dangerous over-reliance on carbon-based fuels is at the core of all three of these challenges – the economic, environmental and national security crises.

Sound familiar?

when you connect the dots, it turns out that the real solutions to the climate crisis are the very same measures needed to renew our economy and escape the trap of ever-rising energy prices.

Hmmm??

So what could we do?
1. Use public transport and lobby for infra-structure projects that support alternatives to petrol based transport
2. Choose green power accredited electricity and lobby for greater access to non-carbon energy
3. Install gas in place of electricity for heating
4. Install solar in place of electricity or gas for heating
5. Install solar for home electricity
6. Ride a bike
7. Grow some of your own food
8. Choose superannuation funds that invest in renewable energy and other world friendly investments
9. Get friends to watch the video
10. Buy less and fewer new things

Most importantly is to talk to your representatives about the choices you would like them to make.

Walking off the emissions price rise – Walk Score

Walk Score is a US-based website that rates a suburb by how many services are within walking distance. Whilst it is focussed on North America, because it uses Google Maps, it works quite well with Australian addresses too.

With the Federal Government’s long awaited introduction of emissions trading – and the logical increase in the cost of transport, this lets you see at a glance how walkable a suburb is.


King St Newtown 92%


Victoria St Potts Point 88%


Union St Dulwich Hill 62%

So check out your street and see how walkable you are.

But don’t be discouraged – the 1 km walk distance they put in place is not very far – and the project doesn’t address public transport availability. And you could always ride a bike – maybe they will create ride-ability ratings soon as well.

Amory Lovins on Winning the oil end game.

TED talks, always a great source of inspiration has done it again. An easy to follow solution to the US and logically OZ’s reliance on oil. Well worth a listen and passing on to your friends.

With support from a forward thinking government, fuel alternatives, as mentioned in my previous post, would be supported by infra-structure changes. Making it possible for business opportunities to replace any losses from traditional hydro-carbon industries.

Peak Oil and Preparing for $8 petrol

The CSIRO Future Fuels Forum has released a report on surviving the increasing costs of transport energy.

The Fuel for thought is about the ways Australia (and Australians) can respond to the increasing cost of fuel, both in the short term but more importantly into the longer term future. Australia is very dependent on oil to fuel our transport – both personal and economic. It is this dependence on road transport that in the immediate future will see costs of nearly everything from fresh food to toothbrushes climb higher and higher.

Director of CSIRO’s Energy Transformed Flagship, Dr John Wright, said Australia’s transport fuel mix will substantially change in response to issues such as climate change and oil prices.

“Securing access to affordable and sustainable fuel underpins Australia’s economy and way of life and as a nation with relatively high vehicle use, we are vulnerable to the economic, environmental and social impacts of rising oil prices and rising temperatures,” he said

You have probably seen that there are predictions that petrol will reach $8 per litre in the foreseeable future, meaning the average family would be spending $220 a week on petrol. I couldn’t afford that so I know I would need to be making lifestyle choices.

Here are some ideas from the report;

Australia’s fuel mix will shift in the near term to include the expanded use of;
diesel,
gaseous fuels such as LPG and
hybrid electric vehicles,
with even greater diversity beyond 2020 that might include;
hydrogen,
synthetic fuels from coal or gas and
advanced biofuels that will not impact food production.

Holden barina
Yesterday i filled our little Barina – costing nearly $70, now that is crazy. So what am I doing about it. Well I rarely drive much – fortunately I live and work close to the train line, and am happy to walk where possible. For those other times I have a scooter which is an exceedingly efficient mode of personal transport. And the car – well we do our best to use it as little as possible – but these are all things done before fuel prices went up because as this report says the other petrol problem is carbon emissions.

Perhaps the most telling part of this report is the single statement;

Results such as this could be seen as a catalyst for early action on the development and roll-out of alternative fuel options, low emission vehicle technologies and infrastructure that supports sustainable transport.

So much of our future fuel resilience will come from clever infra-structure projects that allow everybody to access efficient, reliable, safe, convenient mass transport.
