Reflecting on my interviews with various leaders in the energy efficiency space there are five things you must have to successfully reduce energy use and carbon emissions.

First you need leadership commitment.

Second you need a measurement and monitoring system. Whether you are a school (listen to Hannah Lewis, Westernport Secondary College, which has halved its energy use in the last four years) or a major corporation such as Wesfarmers, you must be able to track your progress.

Third you need more than one person active and driving the program. Witness Linfox, where a few programmers voluntarily took on the extra project of building a carbon tracking tool.

Fourth you need a well informed plan as to what you need to do. An energy audit by experienced energy efficiency engineers will provide this.

Fifth, you need investment. Money is needed to get the savings. The money could be spent on people (eg the driver training undertaken by LinfoX) or technology (eg lighting upgrades at Darebin City Council and Newcastle City Council, or the new paint plant at Toyota). 

Do this and with time you’ll have a self-funding system that will continue to reduce your energy use and carbon footprint.

Yesterday Better Place announced that Canberra would be the first site in the national rollout of its electric vehicle recharge network.

Construction of the network will begin in 2011, with services available to electric vehicle owners from 2012.

ActewAGL - the electricity distribution business and retailer in the ACT - responsible for sourcing and distributing the renewable energy that Better Place will use to power electric vehicles within the ACT. “A significant influence on our decision to choose Canberra was the enthusiasm and support we have received from Michael Costello and his team at ActewAGL” said Evan Thornley, Chief Executive Officer of Better Place Australia.

The deployment of the network will include:

• Recyclable lithium-ion batteries that will power the electric vehicles and be provided as part of the service to drivers, reducing the up-front costs of purchasing an electric vehicle;
• Charge spots in homes, offices, shopping centres and other car parks where drivers can plug in to keep their battery fully charged; and
• “Battery Swap Stations” where motorists can drive in and have a depleted battery automatically exchanged for a fresh, fully charged one.

The vision of Shai Agassi, Better Place founder, is for electric vehicles to be cheaper and more convenient than fossil fuel powered cars. Australia is one of three countries where the technology is being rolled out globally. Its great to see this vision now being translated into concrete plans.

Linfox is well known for the “You are passing another Fox” sign on the back of its vehicles. But the company has also cut its greenhouse gas emissions by 9% in the last eighteen months, and is on track to cut its emissions by 15% by December 2010.

I had the privilege of interviewing David McInnes, Group Manager Environment and Climate Change yesterday and being inspired about Linfox’s approach to the climate change challenge. It was refreshing not to hear the Carbon Pollution Reduction Scheme mentioned once in the interview. Linfox is reducing its carbon emissions because it wants to, not because its being forced to, and is quietly getting on with it.

So how does a organisation with 15,000 staff, whose carbon emissions mostly come from diesel consumed in trucks, reduce its per km emission by 9% in eighteen months? You can find the interview on our “Good News Interviews” page.

For me a couple of the standouts from the interview were:

• Their staff engagement program. Almost all of their savings have come about by making better use of what they already have, rather than investing in new technology. This has been achieved by getting their staff involved in changing the way things are done and in how trucks and buildings are operated, and making hundreds of small changes.
• Their carbon accounting system – developed in-house. Linfox programmers set up their SAP system such that now monthly carbon reports can be generated, down to the level of individual trucks if necessary. A consistent theme of all organisations cutting their carbon footprints is their focus on accurately and frequently tracking their emissions
• David’s recommendation to any organisation wishing to cut their carbon footprint to undertake an energy audit, which provides the business case for action. Thanks for the plug for my profession David!

After the interview we discussed Linfox’s Greenfox program, and I wish I had left the voice recorder on. This is a fantastic program. Staff can become a Greenfox by passing five training modules. Everyone who completes the training gets a framed certificate, and drivers who complete the training get a Greenfox badge on the shoulder of their uniform. David mentioned that Greenfox’s often become ambassadors, with truck drivers going to their kid’s schools and talking about climate change.

Also not covered in the interview was the great help David got from Linfox’s IT department in modifying SAP. Normally there is a long queue in the organisation for projects requiring SAP changes. The carbon accounting adjustments though were undertaken by the SAP programmers on top of their normal requirements, such was their commitmen to the company reducing its carbon footprint.

Finally David also spoke off the record about the need to focus less on the science and more on the community and the emotional response that when sparked can result in great change.

As one of Australia’s larger businesses Linfox is taking a leadership role by getting on with reducing its corporate carbon footprint. David McInnes is providing inspirational leadership. Take half an hour to listen to David McInnes and I guarantee you’ll come away motivated and hopeful about what is possible if we focus on cutting carbon emission.

Today I had the fortune to see Shai Agassi, founder of Better Place, talk about his vision for the electric car future. Shai calls himself an imaginer – “I imagine the future and engineer towards it”. His vision of an electric car future is elegant, simple, and achievable. Australia is a key part of his strategy to get the world to a tipping point which results in all cars becoming electric.

For electric cars to replace petrol cars they must be cheaper and more convenient. Yet the electric cars available now are more expensive and less convenient because of their short range and limited recharging options.

One of the keys to Shai’s vision is treating the battery – the single most expensive component in an electric vehicle – like gasoline. The battery becomes a consumable, not owned by the car owner. By taking out the battery its possible to make vehicles that are price competitive with gasoline vehicles.

A second key is the electricity grid, which is everywhere, and which he called “the longest extension lead in the world”. By extending the grid to having recharging points where cars are parked, vehicles can be charged whenever they are not in use. Better Place will be buying only wind or solar generated electricity for use in its vehicles.

A third key, for longer trips, is batteries that can be swapped over in a minute. The first prototype has just been built in Japan. So on a long trip (over 200kms) you pull into a battery station, change your battery, then keep going. It will take less time to change your battery than to fill your car for petrol. For a typical suburban vehicle typically there would be around 12 to 15 battery changes per year.

Paying per km you travel – for the electricity and battery amortisation – is still cheaper than the equivalent cost of petrol per km.

The result is:

• Cars that cost less to buy than fossil fuel powered vehicles; and
• Cars that cost less to run than fossil fuel powered vehicles.

Of course a large investment is needed to build the infrastructure – the recharging points and battery change stations. But if cars are cheaper, if they cost less to run, if petrol is only going to keep increasing in price, and if there is going to be continued regulation and incentive to reduce carbon emissions this is not a insurmountable hurdle.

Shai believes that the “tipping point” will be reached once three countries have proven the concept. Then the rest of the world is likely to follow – and follow quickly. The first country is Israel, which first supported the idea. Renault are investing one billion dollars in producing a electric vehicle, which will first be sold in Israel; they are aiming to sell 150,000 vehicles in the next few years. The second country is Denmark. And the third country is Australia, with Looksmart founder and former Victorian parliamentarian Evan Thornley heading up Better Place in Australia.  Australia was chosen for a couple of reasons. First its big, unlike Israel and Denmark, and thus provides a demonstration that the technology is suited to big and small countries. Secondly we have large sprawling cities, involving a long suburb to city commute, not dissimilar to many North American cities. A third reason would be that we have a relatively small population of cars, so the net capital cost is relatively low. Shai also said that Australia has lots of Lithium, iron and phosphate, the components used in electric vehicle batteries.

With a country full of electric cars, each with large storage capacity, the intermittent nature of electricity generation from wind and solar can be overcome. When the wind blows and the sun shines batteries in parked cars everywhere will be charged. When its calm and cloudy cars can then feedback into the network. And we move towards the smart grid or distributed network.

The choice of Evan Thornley as Australian CEO is interesting. Clearly Better Place will need tremendous IT and communication infrastructure to communicate with vehicles and the smart grid and monitor battery condition and charge levels. Its hard to go past one of the people who was involved in driving widescale uptake of the internet as a leader.

This future is not that far away. Various governments around the world are now offering subsidies to those who purchase electric vehicles. And in Beijing gasoline cars will be progressively banned from the streets. By 2014 no fossil fuel powered vehicles will be allowed in Beijing.

Shai believes that within 10 years we could have three to four million drivers using electric vehicles in Australia.

Shai Agassi spoke at the inaugural 2009 Alfred Deakin eco-innovation lecture. These lectures will feature optimistic innovation driving a more sustainable world. Shai’s positive vision is a great inspiration and a fantastic way of kicking off the lectures.

Virtual desktops provides large computer energy savings and are becoming easier to deploy. Great for schools, universities and offices!

Most of the time only a small fraction of a computer’s power is being used. If you took a office or school with say 100 PCs, with an average load of say 15%, in effect 85 of the PCs would be redundant if it was possible to take advantage of the full power of 15 PCs across 100 work stations.

By employing “thin client” or “virtual desktops” this is made possible. With virtual desktops one PC “box” can then be used to power multiple workstations. This leads to very large energy savings. Additionally by reducing the number of “boxes” there is a resource saving. Maintenance costs are reduced and total lifecycle cost is lower.

There are some impressive examples of where this technology is now being used. Ncomputing is a vendor of virtual desktops, with 180,000 units deployed in schools in Macedonia. Canon in Thailand are using virtual PCs, as is DHL in Peru. In the USA virtual desktops are being used in schools in California and Wisconsin. In Australia its customers include schools such as Wondonga South Primary (Vic), Brighton Public School (SA), MacGregor State High (Qld).

In Australia Gold Creek and Parlmerston district schools in the ACT are using thing client computers supplied by Dycom. RMIT University in Melbourne is also using thin clients.

Take up of thin clients could however be much stronger. Victoria’s Department of Education and Early Childhood Development has reported weak demand from schools inquiring about the National Secondary School Computer Fund which is part of the Commonwealth Government’s Digital Education Revolution.

The flexibility of notebook computers is certainly an advantage over thin clients. However for total minimum power use and minimum life cycle cost and resource use its hard to beat a thin client or virtual desktop system. Thin clients should certainly be seriously considered by anyone involved in computer purchasing and network administration.
