Thank you, Ron, Mr, being up here, I guess. Look, I'm largely in favour of the consultant's report that you've had. It's pretty complete. You're all aware now that I've owned an electric car for a bit over five years. Back of the program calculations this afternoon is I've avoided 2,700 litres of petrol burnt through it by using my BMW i3. There are some missing details in the consultant's report. It is written around directly about just council for cars, but there's a few things I'd like to point out. It was also written in September of last year, so there's been a lot happening since then. But to start off with, not in the report is that you have a potential to lower your CO2 footprint by using biofuels in existing vehicles, and vehicles that can't be readily used as electric vehicles.
So I'd point out that E10 petrol reduces about 10% of your CO2 compared to regular 100% petrol. You have no noticeable power loss or engine modifications. You get cleaner burning, potential small savings in fuel costs due to reduced excise. Use, instead of the higher octane fuels, we should be using at least 10% blended petrol instead of higher octane fuels where possible. Any vehicle that's using a high octane rated fuel than is actually necessary for the engine is completely wasting the fuel, and you're paying more money to do the same job. Another thing to consider that's not mentioned in that report would be when buying vehicles, if we're buying hybrids, we should be looking at them being able to be used, say, E10 fuel at no more than 94 octane rating, simply because we can save money on the fuel.
There is another ethanol blended fuel that's not normally used, that's E85. It's difficult to get. It certainly gives you a lot more benefit on CO2 reduction. Flex-fuel vehicles can use it. A lot of cars now with fuel injection will automatically re-tune the motor. For whatever fuel is being run. Unfortunately, E5 is largely was available in Queensland for a short period, but E85 is regularly used overseas. A lot of it's used in Brazil and in America. So it's just another one of the fuels. But by using a biofuel blend, you are reducing your CO2 footprint, so that can go into Council's accounting immediately. So that needs to be considered. Now, regarding diesel vehicles, a simple swap from regular diesel fuel, if we're not using it, to biodiesel would immediately give you an instant 100% CO2 offset because it's a renewable fuel.
Qantas, you may have read, is recently trying to swap to sustainable source jet fuels. They're hoping by 2030 to be able to use 10% of sustainably sourced fuels, and they're carbon neutral in their fleet. But not much biodiesel has been made in Australia. It's big in Europe. You may have a potential to buy biodiesel through maybe you're purchasing through WSROC, but it would immediately allow all of your diesel vehicles to effectively be counted as carbon neutral. Especially important going into the future where the consultant does say some vehicles are not suitable for electrification, like your street sweepers, maybe dozers, et cetera, down on the tip. All of those can be run on biodiesel, and that would immediately give you a carbon dioxide offset.
So that would help with your budgeting there. Another point is many new electric vehicles are coming to the market since your September 21 consultant dating. There are new tradie and heavy vehicles that are coming. Ford has just doubled the size of its big ute plant in the United States to 100,000 vehicles, not the 50,000 they'd started with. Many of these large utes and trade vehicles have mains voltage power outlets for off-site use remote from 240 volts mains or generators. That's an interesting thing. It will certainly help with your yard staff, et cetera, being used in vehicles off-site, so they wouldn't need to carry generators, for example. And you can recharge power tools or run directly off the main battery.
The computer on board these vehicles monitors the charge state, and it'll cut you off pretty quick if you're getting too low on the running range of the vehicle. A third point is council vehicles will be charging off carbon neutral electricity from your bulk purchase at your larger buildings, courtesy of Mayor Calvert. We have an 80% renewable energy purchase, so any of the electric vehicles you're charging at the large facilities will automatically be carbon neutral, and that's not to also forget your on-site solar. Areas where you could be charging during the daytime. So you would want to avoid charging electric vehicles, ideally from the smaller buildings that aren't on that renewable power purchase.
So you immediately do some significant things about reducing your CO2 footprint. But once you start purchasing and charging your own vehicles off council's capacity, the charging analysis in the document I largely agree with. Most fleet vehicles are probably only going to be doing maybe 100, 150 k's a day, and that's well within even slow charging. So really, you don't need to be fast charging in most cases. I agree again with the consultant's report. My experience is I've done 45,000 kilometres off my rooftop solar. I have never activated my BMW's charge cards, and in doing that I have saved something like 2,700 litres of fuel in the five years I've owned my i3. I find charging at 10 kilometres per hour quite acceptable, and you also don't need to upgrade any of the power systems that you're plugging into because you're only running at the equivalent power use of about a one-and-a-half-bar radiator.
So you could have two or three cars easily plugged into any standard circuit, in my opinion. So as far as council policy regarding charging, fast charging, etc., you're unlikely to need it for your own vehicles, and they're right. There's only about, well, they did say there's 30 vehicles in the area, so at the writing of that report I was one of 30. I'm probably one of about 40 now. There's a few new Teslas around. I've seen a lovely white one today, for example, but I'm not going to get jealous about that. Daytime charging where vehicles are parked can be made routine. You just have to get staff into the use of plugging in if there's charge facilities available, as well as overnight charging.
If you can charge during the daytime. There's advantages about that that I can mention later. Not mentioned is also the 240 volt outlets of the new tradie-type vehicles that will be coming, because the power batteries run at 300 plus volts. It's easy to build inverters into them that will put 240 volts out, and vehicles will probably, most tradie vehicles will either come with them as standard or with options. Similarly, large other vehicles that you might purchase would probably come with those sorts of facilities. There's also not mentioned is the potential for the new electric vehicles to go into smart grids. We're already talking, at Origin supposedly, about putting in a grid with a battery.
You've got to remember that electric car batteries are capable of probably powering about three houses in parallel overnight because of the size of the batteries. They are large, the electric capacity. Smart grids, there's one in trial in Canberra at the moment that users Nissan Leafs because they have the ability to feed power back into the grid, computer controlled. The grid can demand plugged-in vehicles to feed into the grid, so you can smooth out brownouts and power shortages. You can build resilience into the grid without having to install a battery. You have to have agreements between the vehicle owners as to what they're prepared to run down, and also the utility pays the owner of the vehicle somewhat of a premium compared to what they're buying electricity at in order for that facility to happen.
It's certainly been well written up, and it's been done overseas in some places, so it gives you a way of having resilience in the grid without actually going and installing separate batteries, as was, say, done, for example, with Tesla in South Australia. In South Australia, by the way, the— The Tesla battery was said to have paid back within less than a year or so, simply by allowing the grid to operate more smoothly and the operator not to buy peak power at very, very high prices. So there's a chance there. A trial like that could possibly be done through University of Western Sydney. Certainly the Nissan Leaf is the car that's mentioned at the moment. Other cars coming in will have the ability.
Some can be ordered with that capability of feeding back to the grid. Now, in theory, you can also use the car for your own home battery. Again, that depends on charging requirements, et cetera, et cetera, rather than putting in a Tesla Powerwall or similar. In my case, a thousand kilos of lead-acid battery sitting at 48 volts, you can actually use the car. Cars have massive capacities in those batteries, and for houses that have one or two electric vehicles potentially in the future, that will happen. One vehicle would probably be the general run-around hack that might only do 40, 50 k's a day taking kids to school, so it would be sitting overnight with a hell of a lot of spare capacity in the battery that could potentially be used overnight to run the house.
Again, there's some legislation required and utility cooperation currently involved that would be required. It would certainly give resilience in the Hawkesbury during floods and fires that we've had shutdown of communications, et cetera. If we can do that, if we have vehicles, even tradie vehicles with large batteries capable of running communications, et cetera, in the field when the grid goes down, big tradie vehicles with 100-plus kilowatt-hour batteries could probably run four or five days worth of communication without being recharged. They could also be recharged off a generator, et cetera. So there's potential to do things that really haven't been considered in the report, but then the report from the consultant is about directly for council's use.
Further not mentioned is charging off rooftops. which I do and have done for five and a bit years very successfully. I can also charge off my home battery. So again, this is the slow charge scenario. I simply don't need the fast charge. If I was fast charging at home, it was going to be about another five or six hundred dollars for the semi-fast charge setup. But to go to extreme fast DC charging, the consultants are right, you're talking in probably, you know, $10,000 or more because you simply have to have a lot of big cabling going in. It's not a cheap option. And then you have to have all the electronics, et cetera, to run it all. So overall, there's potential for improved resilience with these new vehicles that are coming in, especially with the 240-volt power outlets.
As these vehicles become routinely available and right through the area, we have potential during floods and fires to keep communications and other things going. It's well worth considering in the longer-term resilience side of the environmental question that we're considering here. Charging during the daytime off the solar system is also beneficial because if you are being paid a relatively small amount to export to the grid, you're better off to use that power during the daytime to charge the car or to run washing machines, etc. All energy advisors will tell you that. I, for example, get 11 cents a kilowatt hour for export. My buy-in price is 30 cents a kilowatt. So every kilowatt that I can use during the daytime, while I also have batteries so I can run overnight.
But if you only have solar panels, you are better off to be using the electricity you generate during sunlight. So charging a car during the daytime is another way of doing things. Now, if you were capable of running the house off the car during at night, you would then have a mobile battery, not a hard-wired battery on the wall like, say, a Tesla or an LG Chem or something or other battery. Another advantage of this charging is in some areas where there's a lot of solar installed, there is a voltage rise that comes during the middle of the day when all the panels are feeding in. It's called an island effect, and by charging cars and using the power during the daytime, you're putting more demand into the grid directly off your house and you reduce that problem.
It's a major problem that's coming with some of the utilities, particularly at the end of wire runs or where there's a large amount of power being generated in a relatively small area with large solar rooftop systems. So there's a lot of opportunities here for council. I really have commended council in the past for what we've done with solar, with heating, etc. We've picked the low fruit. We've done it very carefully, and I would anticipate the same thing will happen with electric vehicles. And quite frankly, if you don't think the electric vehicles are coming, the tsunami is going to hit you a bit like in Tonga. There's about another six or eight vehicles being released in the last few months.
There's a big new Chinese company that's doing fleet buys in Sydney. One of the problems, though, with a lot of the vehicles is at the moment they are short utility-style vehicles, because that's the big part of the general market. It's also done to get the flat battery pack with a low centre of gravity on the bottom of the vehicle. So as far as lease-type vehicles for staff, there are not a lot of sedan-type vehicles on the market, although the Nissan Leaf is one. I'm not particularly pushing Nissan. I could push BMW like crazy, but you probably don't want to be paying $150,000, as you don't want to for the top of the range Teslas. So Teslas have now come in. But in all of this as well, you've got to be looking at the economics.
The dilemma that we have is really the federal government has done bugger all to help with anything with our energy policy. They're being pushed like in the United States to a fair extent by the states and private companies. So anyway, here endeth my discussion. Any questions?
