Ethanol has about two thirds the caloric value of petrol so each 5% increase of ethanol reduces the calorific value of the fuel we buy by 1.6% ie one twentieth of a third hence the 1.6%.

The 1.6% difference in calorific value is a scientific fact. When one is buying E10 one is buying a higher percentage of Oxygen in the fuel rather than hydrogen and carbon. Hydrogen and carbon provide the energy when their atomic bonds are broken, oxygen is the atom that gets added to the carbon and hydrogen to make the CO2 and water, effectively when one is buying E10 one is buying air/oxygen that would normally be free if one was just using pure petrol without ethanol. So in a perfectly set up engine one would get 1.6% less power or less fuel consumption with E10 over E5. If an engine is working perfectly this would be the result but if an engine was running a bit lean, for some engine management unit issue, one might get parity or even better mpg with E10 over E5 but the logical conclusion is 1.6% less mpg with E10 over E5 or 3.2% over pure petrol.

"Don't do Hitler salutes" ! Okay.

Yes even the Zoe is put around the Ring, did quite well.

Happy with the Regen "B" level of my new Riviera Zoe, it can amount to 30 kws going back in to the battery. I was keen to get a 64 kWh Leaf as they have similar range to the 52 kWh Zoe but I would had to wait at least 3 more months for it. Great deal on the Zoe with nearly £9k of the RRP with government grant, Renault contribution, Delear contribution and great trade in. Also £350 off the house charging box. Expect deals might not be as good now as a couple of weeks ago as EVs become in even more demand. Heat pump car heating and aircon seems to make that a not too painful thing to have on. Like all EVS, except the non SUV Teslas, the rate of energy consumption at indicated 75 mph seems to hurt the range a lot and I do not know a clever way round that except to trade for a model 3 or 100 one day.

Just talking to a colleague who I work with at Heathrow and he could not find fuel for a 10 mile radius around the Chelsea training ground then phoned and found some 15 miles away but they only let him have £20 worth. He drives a Land Rover Discovery so I dread to think how much that moved the dial.

Bought nearly £50 of diesel in Tescos Warndon Villages Worcester, small queues and no limit on how much one bought. We have the 4 laws of thermodynamics............ Love the fact there is a Zeroth law, like, oops, we need something before the 1st Law.......... https://chem.libretexts.org/Bookshelves/Physical_and_Theoretical_Chemistry_Textbook_Maps/Supplemental_Modules_(Physical_and_Theoretical_Chemistry)/Thermodynamics/The_Four_Laws_of_Thermodynamics 0th Law of Thermodynamics The Zeroth Law of Thermodynamics states that if two systems are in thermodynamic equilibrium with a third system, the two original systems are in thermal equilibrium with each other. Basically, if system A is in thermal equilibrium with system C and system B is also in thermal equilibrium with system C, system A and system B are in thermal equilibrium with each other. 1st Law of Thermodynamics The First Law of Thermodynamics states that energy can be converted from one form to another with the interaction of heat, work and internal energy, but it cannot be created nor destroyed, under any circumstances. Conservation of Energy First Law of Thermodynamics 2nd Law of Thermodynamics The Second Law of Thermodynamics states that the state of entropy of the entire universe, as an isolated system, will always increase over time. The second law also states that the changes in the entropy in the universe can never be negative. 3rd Law of Thermodynamics The 3rd law of thermodynamics will essentially allow us to quantify the absolute amplitude of entropies. It says that when we are considering a totally perfect (100% pure) crystalline structure, at absolute zero (0 Kelvin), it will have no entropy (S). Note that if the structure in question were not totally crystalline, then although it would only have an extremely small disorder (entropy) in space, we could not precisely say it had no entropy.

Well yes, patently. https://octopus.energy/blog/100-green-what-does-it-mean/ At Octopus Energy, all of our tariffs are 100% renewable electricity – which means we will match every unit of electricity you use with a renewable certificate for the same amount. This matching is done through Ofgem’s REGO (Renewable Energy Guarantee of Origin) scheme – the system used by suppliers across the U.K. to verify their claims of the amount of renewable energy supplied. Alongside our REGO certificates, we contract directly with renewable producers, such as solar farms or anaerobic digestion plants, on Power Purchase Agreements, or PPAs. Finally, we're a part of the Octopus Group – the UK’s largest investor in solar generation, with over £2 billion invested so far. That investment alone generates enough power to supply a city the size of Manchester. As well as wind and organic waste generation, Octopus Group invests in ‘smart technology’ to help build a new way of supplying and generating energy around the UK. One that will be based on a more transparent, push-and-pull network of tomorrow, helping to provide some much needed flexibility in the energy industry.

Well I am with Octopus Energy which is supposed to be drawn from 100% renewable. As to carbon molecules coming from brakes, tyres and even the carbon brushes on the electric motor, yes there could be a few. I hard use brakes any more as I you regenerative "B" mode braking and am more concerned about the D head in the ICE behind me getting too close as he accelerates and then destroys all hist kenetic energy in his brake discs heating up as lost thermal energy. Hopefully Renault, and the other EV manufacturers have got it right and our EV brake lights are coming on or even flashing as we harvest kinetic energy and put it back in the battery pack as does an F1 car. I have seen the little Zoe putting up to 30 kW back in to battery on some occasions. Still need my diesel and petrol cars and motorbike as back up, only charging the Zoe at 2 kWs until Friday when I get my wall charger. Thanks to the Con government for the £350 bung as part of the OLEC grant for the wall charger making a total of £2,850 for them to change to electricity, wish I had done it in spring rather than autumn. Nice to use the smart phone occasionally to check its charge status so I can holt the charging so I can cut it off to get the 4.5 hours of nearly free electricity on the night rate. I hear crude has gone up 20% in the last 5 weeks so we should expect both more expensive fuel as well as shortages. Government has the ability to tweak the excise duty to level up the level of tax as their is VAT on the cost of the oil and on the excise duty so they have the power to stop it going to over £1.40/£1.50 a litre.

Dacia are still going great guns with B-Fuel LPG/Petrol but it is not ease to know where to get LPG as it does not seem to be well advertised. When the Clio comes up for renewal then a Bi-Fuel Sandero or other Dacia will be top of the list.

After a fruitless search last night for diesel and 5 Worcester garages good to see local Tesco garage open and whilst busy I managed to get £48 in the diesel Fabia so that should be good for 600 miles driving. Daughters coming back from London last night had to fuel up at Chiverly motorway service who were rationing to £45, thankfully that is not far short of a 3/4 a tankful in a Fabia and she could drop off one daughter in Bristol and return to London to start at 0600. Mad times. Some were cheating taking £45 at one pump whilst the passenger filled to 20 litre Jerry cans at the other pump and paid for them separately. Zoe did Worcester to Bristol and back with no carbon molecules being harmed in the process.

I cannot see these attached images for some reason. There is (was?) apparently about a billion litres of space in cars fuel tanks, wonder how much there is in vans, trucks etc even motorcycles. I will try and get some diesel tonight when the super market closes but their fuel station stays open. Will charge the Zoe tonight at home on the cheap electricity and may have to use it more than I anticipated if fuel shortages continue. Excise Tax on a billion litres would be £580 million pounds plus the VAT of around £225 million. Be interesting to see if the refineries step up to replace their on hand stock.

Hi George, what have you raised your tyres pressures too, and that is on your 17" wheels. Is your current range shown after charging 160 to 170 miles looking at your phone app ? I have been slow to install the Renault app as it so badly thought off, mainly the English version of the software which the French do not seems put much effort in to the UK language version. I chickened out of my 200 mile run down to Reading and back as I wanted to do it at 75 mph indicated average and with 3 people in the cars and I did not think the Zoe would do it. So may tricks and optimising techniques to learn, such a good community though both the EV and Zoe ones, so glad I took the plunge.

Getting my Pod Charger fitted next Friday. Octopus say their Go tariff is only a Beta product so can change at any time, we will see. Zoe charged up on granny cable and now showing 100% and 241 miles range. Will try and do a 205 miles to Reading services and back without mid journey charge. Got all my 12v bike, car, scooter batteries to charge up and got a 1000w 12v to 220v ac invertor on hand to keep the lights one. Queue. Apparently there are only a few thousand place where you can get this liquid that internal combustion engine cars use compared to millions of electricity outlets, off choice of motive power. https://news.sky.com/video/motorists-queue-at-petrol-station-after-delivery-issues-caused-some-closures-12416523

First medium distance trip, Worcester to Oxford Airport and then back to Worcester a few hours later. Round trip distance 106 miles. 100% charged when started and 56% charged when got back to Worcester. This would give the range as 241 miles. Mostly driven in ECO mode which was fine. Display showed 4.4 miles per KWh which would work out as 229 miles for all 52 kWh. Chickened out and took the diesel Fabia to Heathrow today. Figured out why the chargers at Heathrow office say 16 Amps but also say 11 kWs. They are 3 phase chargers ! So should be good to get a good charge in only 3 or 4 hours if I was only down there for a morning or afternoon. Trip planned from Worcester to Reading service and back which is nearly exactly 200 miles so see how it goes.

I think I need to check what my voltage is to the charge box, I was just thinking that plugging one extension in to another, one a couple of meters and then another 15 metres and then plugging in the meaty wired 3 pin charger with its much thicker wiring. It cannot be good to attach 13A and even 10A extension leads and then plug in the car charging 5 metre lead. I would hate to think I am only getting 220 volts https://www.spenergynetworks.co.uk/pages/voltage_changes.aspx Manufacturers usually allow a further margin of safety and, if the voltage does occasionally fall outside these limits, there should be no adverse effect on your appliances. In the UK, the declared voltage and tolerance for an electricity supply is 230 volts -6%, +10%. This gives an allowed voltage range of 216.2 volts to 253.0 volts. --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- I have learnt something new today !!!!! https://www.leadsdirect.co.uk/knowledge-base/what-is-the-difference-between-uk-voltage-and-european-voltage/ What is the difference between UK voltage and European voltage The voltage used throughout Europe (including the UK) has been harmonised since January 2003 at a nominal 230v 50 Hz (formerly 240V in UK, 220V in the rest of Europe) but this does not mean there has been a real change in the supply. Instead, the new “harmonised voltage limits” in most of Europe (the former 220V nominal countries) are now: 230V -10% +6% (i.e. 207.0 V-243.8 V) In the UK (former 240V nominal) they are: 230V -6% +10% (i.e. 216.2 V – 253.0 V) This effectively means there is no real change of supply voltage, only a change in the “label”, with no incentive for electricity supply companies to actually change the supply voltage. To cope with both sets of limits all modern equipment will therefore be able to accept 230V +/-10% i.e. 207-253V.

Just tried to charge with my 3 pin charger from 95% but it did not a want to know with the charger box saying car was already full. Just keen to check lead is working. Have to go do some more miles and try again. Should find a public charger and try to charge there, Asda maybe.

16 inch Alpine or 15 inch? I was getting near 4 miles per kWh but then decided to do my first full power test up a dual.carriageway hill and 84 mph came up quickly, not as quick as the 150 hp octy but quicker than the 90 up Clio or Davis despite it's 1600 kg running weight. I see the cash still saying full regen is not available as battery full, battery says 95 % full after 18 miles. I am suspecting one can charge the battery to about 102 % of nominal but it shows 100% for six miles rather than dropping 1% per two miles as I expect.

Not "EV" marked tyres on the Zoe I picked up yesterday. The Usual Primacy 4s in Heavy Duty/Load spec. All 4 tyres set to 36 PSI by the dealer so I corrected those fronts to 38 PSI to help prevent torque ripping and outer edge wear that is associated with the lower tyre pressures. Left the rears at 36 rather than drop to 33 psi as the sticker states. No advised tyre pressure for when one is carrying several people plus luggage, again a bit odd, hence 36 seems OK or maybe even 38 in the back tyres too if the ride is not too firm. Some more miles today and continue to think about some winters maybe in the 15" size 185 width, not sure whether they will be All Seasons or full winters, probably All Seasons, keep those nice Diamond cut OE rims in pristine condition.

Well picked up new Zoe Riviera this morning. Car computer showed 236 miles range with 100% charge. Drove 5 miles to home, range dropped to 231 miles but battery meter still shows 100%. Will do the 15 miles I normally do on the motor bike and then see where we are on battery charge and then test my new granny cable ie the 10A 2.4 kWh cable.

We do there has been little wind in August and September so far. Wind usually pick up closer to the equinoxes, Vernal or Autumnal. All areas of Green agenda need to keep moving forward, more wind turbines and more battery power storage as well as a big exercise to insulate people's homes. Some perfect storm elements at the moment, low wind but also the fire at the 2 GWh France-UK Interconnector is bad news as we currently rely in the French nuclear base load stations for up to 7% of our electrical consumption. Diversity in supply, weighing up all the changing parameters, whether that is the type of power for out transport or the power for out homes.

Indeed as it is up to 10% ethanol but one would expect if ethanol is a cheaper ingredient then the oil refineries will use as much ethanol they can up to the 10 % allowed. As I said I think it will be interesting if some fuel companies bring in some of the worse quality America, North or South, fuel and use the bio-ethanol to bring the fuel up in octane. I pick up the Zoe R135 tomorrow morning, it will good to know that electricity is electricity is electricity. I have got Octopus Energy to change me over to Octopus Go tariff from tonight, 5p per kWh I think from 0000 to 0430, and I will probably order my Pod Point 7.2 kWh home charger over the weekend. I pickup one of my daughter cars, a Mk 4 Zoe with the 0.9 TCE engine in it, this engine was one that one of the car mags reported a 9% or so increase in fuel consumption so I will see how that goes on the E10 as I use to get 55 mpg or so out of that engine on E5 or even mid 60 mpg when set in Eco mode and sticking to 55-60 mph, but that is painful. With the world going crazy on resources, prices get unstable, diversifying the types of fuels one can use seems wise and keeping fairly full tanks and batteries. Next stop static battery store.

The Ethanol can boost the octane rating and if one was running a bit too rich it makes the mixture a bit leaner by having more oxygen in the air/fuel mix. Cars with lambda sensors should self adjust but there is always a bit of sensor/fuel mapping guessing there so it could go the right way or go the wrong way. Less calorific value is a fact though. It could tempt so fuel companies to buy even poorer quality fuel that might knock but mix it with the 10% Ethanol and it ups the octane rating up to 95 so one starts to see poorer quality fuel than we would normally see in the UK. E10 is just another one of a hundred nails being put in the ICE coffin ie make diesel/petrol cars worse and worse to own so EVs increasingly become the logical choice.

So E10 is costing the retailers about 1.5 pence a litre less than E5 according to the AA article. https://www.express.co.uk/life-style/cars/1492381/e10-fuel-changes-petrol-cost-price-aa Is this being passed on ??? Considering the fuel could well be giving 2 or 3 % less mpg due to its lower calorific value ? Anybody on a regular commute done back to back comparisons yet in their cars ??
