might in the future. They learned they could do better with gasoline because they could make the car very lightweight. At perfect conversion, you get about 36 kwh in a gallon of gasoline. The local mix varies a lot. 3.61 × 10 6 joules is 1 Kwh and 1 Kwh can run a TV for about 24 hours. We don't collect information from our users. Compressed Natural Gas. They looked at the inherent chemical energy in a gallon of gasoline -- this is roughly 120,000 BTUs. When they get to be perhaps 30% of cars it might change. Even the largest Tesla EV battery (100 kWh) can be fully charged from the sun without interacting with the utility grid. This page or section includes content from, Oil Industry Statistics from Gibson Consulting, Appendix B, Transportation Energy Data Book, Overview of Storage Development DOE Hydrogen Program, Bioenergy Feedstock Development Programs at Oak Rodge National Laboratory, https://www.appropedia.org/w/index.php?title=Energy_content_of_fuels&oldid=499926. If we ever get sufficiently cheap solar, we may find that the 3 PM - 4 PM peak air conditioning loads will be very nicely covered by the peak solar panel output. Found inside – Page 38Reduced Fuel Economy The fuel economy ( miles per gallon ) of Phase 1 and ... energy ( Btu ) content of RFG is lower than that of conventional gasoline . One is the power it took to make them and the emissions involved with that. That's because the power from your panels will reduce demand for coal and you should put every watt-hour you have into that rather than avoiding gasoline. There it was your decision to live there that made the difference. CNG is produced by compressing natural gas to less than 1% of its volume at standard atmospheric pressure. I don't see that as much of a win. People go all irrational for this idea -- literally on my block there was a story that got national attention when a neighbour who was trying to have enough solar panels to power his car got a legal order forcing another neighbour to cut down his redwood trees which had over the years grown to shade some of his panels. There are no big gasoline power plants, though there are some oil ones. This calculator allows you to calculate the amount of each fuel necessary to provide the same energy as 1 kg of hydrogen, 1 million cubic feet natural gas, 1 barrel of crude oil, or 1 gallon of other fuels, based on lower heating values. Significant amounts of oil are imported, sometimes from unfriendly areas. Only emails and answers are saved in our archive. In a similar way the energy equivalency between gasoline and hydrogen gas can be found. The variation in quality may give heating values within a range 5 -10% higher and lower than the given value. To do this I'll need more data on all the pollutants from the various sources, and also data on how dangerous they are. A gasoline-charged hybrid is more efficient, to be sure, but a 28 mpg Toyota Highlander Hybrid is still going to dump 20% more of everything into the air than a 34 mpg Honda Civic even though the Civic runs on gas 100% of the time with no electric assist ever. Here is a rough estimate of how much it will cost to fuel a generator, by varied fuel types: Gasoline generator. The EPA used an 8% lower number than perfect, presumably for this reason. This average price is for a single day. Unusual charging on a 5,000 mile electric car road trip, Good and bad about using a 12v fridge on a Tesla road trip, MobilEye announces plans for robotaxis in Munich, You want Tesla's Chademo Adapter for road trips, it's like more range, Forget smart cities, you need to make your infrastructure stupid to survive the future, Using electric school buses to power the grid / Remote driving and Starlink. but not for GHG. The conversion factors for this calculator are documented in the Energy Equivalency of Fuels table. This could work out, but in reality with an electric car the battery is a bunch of weight, even with NiMH, and you don't want to carry around a big one all the time but not get the range from it. (Yes, it's possible to do better than perfect conversion when it comes to GHG emissions, in fact you can do an almost infinite number if you had completely GHG-free electricity.). What I've learned is that at least for now, the use of traditional sedan sized electric cars not a big win compared to hybrid gasoline cars like the Prius, at least on the average grid. In 2000 the United States Department of Energy DOE established the methodology for calculating the petroleum-equivalent fuel economy of . energy content per gallon gas: 6,500 Btu at 3,000 psi gas: 33,000- 38,000 Btu at 3,000 psi 109,000- 125,000 Btu 128,000- 130,000 Btu autoignition temperature (°F) 1,085 900-1170 495 600 latent heat of vaporiza-tion (Btu/lb at 60°F) 192.1 219 150 100 This also is highly locally variable, with very high numbers in the coal states and nice numbers in the hydro and nuclear powered areas. Cost effective NH3 has historically been priced competitively with gasoline and petroleum on an energy content (i.e., $/MM BTU basis). Energy density is the amount of energy stored in a given system or region of space per unit volume or mass. The USA doesn't have to have so dirty a grid. The lowest average is in Houston, at $2.74 per gallon. 2 heating oil or * Natural gas composition may vary a lot between different markets, ** Short ton, 1 short ton = 2000 lb = 907.18 kg, 1 metric tonne gasoline = 8.44 barrels = 1342 liter = 42.8 GJ, 1 US gallon diesel = 129000 Btu  = 136 MJ = 36 MJ/liter, Fossil and Alternative Fuels Energy Content, en: fossil fuels energy content oil barrel gasoline diesel coal natural gas alternative. Bio-diesel average density = .88 metric tons per cubic meter Residual Fuel 1 gallon = 149,700 Btu - HHV * . FUEL SAVINGS EXAMPLE ENGINE EFFICIENCY I know that wouldn't make sense to get a number from a small portable home generator, but I know there are much bigger diesel generators that we could at least approximate with. There are no solar electrons. The biggest one today is greenhouse gas (GHG) emissions, which I will cover below. Research I have seen suggests that coal-powered electricity has about 1000g of CO2 per kwh, while natural gas has about 500g. To properly meet green goals, solar panels must be connected to the power grid. At $2.50 per gallon of propane, natural gas would be a more cost effective energy solution. For example, to find out how many oil barrels there are in 10 cubic meters, multiply 10 by 6. This means that $15.00 will purchase approximately 1.03 million BTU's of energy. These applications will - due to browser restrictions - send data between your browser and our server. Providing peak power to the grid will shorten battery life, the question is how much and how much that costs. potash fertilizers 5,215 BTUs per pound. Some of our calculators and applications let you save application data to your local computer. More research shows the question is complex and messy. LPG BTU per KG - LPG Energy Content Gas Unit Conversion. The weight-density of gasoline is about 740 kg/m³ (6.175 lb/US gal; 7.416 lb/imp gal). However, with an engine tuned to the use of LPG (i.e. And there are also lighter electric cars. will start noticing that their gas tax revenues are dropping and will simply start adding them to kilowatt charges for electricity being used for transportation. Also consider that right now, we have the mining and manufacturing infrastructure to end up with something on the order of one pound of lithium ion batteries per person in developed countries (where the one pound is a very rough guess at the weight of laptop, cellphone, etc batteries). The "burning" question for electric cars is how to compare them with gasoline. In reality, 100mpg real is better than 170 mpg-e(perfect) and the Edison2 is a deserving winner. Hydrocarbons and CO: very good. For example, some of the hydrocarbons are carcinogenic, and we need numbers on the scale of their effects. Most of all, we can go for lighter more aerodynamic cars, particularly the single person commuter cars that robocars make palatable to the commuting public. As in all total cost "well to wheels" calculations you will find a lot of variation in the final numbers, but I think these are close enough for rough calculations. Most engines that exceed 7,000 RPM can benefit more from a 115,000 BTU per gallon gasoline than a heavier gasoline that may contain 125,000 BTUs per gallon, but does not have time to completely burn in the combustion chamber. Aboard the Energy Observer, a French hydrogen/solar/wind powered boat, Theoretical perfect conversion (EPA method): 99 mpg-e(perfect), Heat energy formula (DoE national average): 37 mpg-e(heat), Cost of electricity vs. gasoline (untaxed): 75 mpg-e($). Using your incorrect number of 146,000,000,000 gallons of gasoline it would require 2000 electric plants of 1000 MW each. People really do want to know how much the energy will cost to go a mile. No. 4 Distillate fuel with 15 ppm to 500 ppm sulfur content. I thought the big incentives were federal. This does not apply, of course, if you have decided to live out in the country beyond the grid. 2 fuel oil usually has an energy content of 140,000 Btu/gal (7% less energy per gallon than No. Cost effective NH3 has historically been priced competitively with gasoline and petroleum on an energy content (i.e., $/MM BTU basis). Problem is, had the EPA used that number, it was more than double the perfect energy conversion number and it would have looked really ridiculous. The given values are for fuels with the given density. Quite commonly people will say they just plan to run their electric car on solar and thus have no pollution at all. Found inside – Page 17The average value for ethanol blended in premium gasoline in this market would ... Therefore, the net energy debit is only about 20 percent per gallon of ... I've also seen credible arguments that due to the fact that about 1.5% of the natural gas pumped in the USA leaks into the air, and that methane is anywhere from 80 times (20 year average) to 20 times (100 year average) more potent a GHG than CO2 is, the figure for natural gas generation should be higher, more like 700g. In that fuel taxes are probably basically regressive, this may not be entirely terrible. Sometimes one can make assumptions without getting the entire picture of something. A decision to not connect because you want no part of the grid is an environmentally destructive decision. Drive your electric car in Canada and you can put on a big green smile, pollution and GHG wise. The Department of Energy studies all the power plants in the USA, and their efficiency is calculated and averaged. Most engines that exceed 7,000 RPM can benefit more from a 115,000 BTU per gallon gasoline than a heavier gasoline that may contain 125,000 BTUs per gallon, but does not have time to completely burn in the combustion chamber. If the initial and final temperatures of the water . Nationwide, the highest average price for regular-grade gas is in the San Francisco Bay Area, at $4.48 per gallon. California calculated that 9,000 people die per year due to particulate pollution -- that's more than die from car crashes. So messy that the best solution is for electric cars to publish their efficiency in electric terms, which means a number like "watt-hours/mile." So, as 1L = 25 MJ then 25 MJ x 948 = 23,700 BTU per litre. This book considers technologies to increase energy efficiency, coal-fired power generation, nuclear power, renewable energy, oil and natural gas, and alternative transportation fuels. more_vert (II) A four-cylinder gasoline engine has an efficiency of 0.22 and delivers 180 J of work per cycle per cylinder. This tells you that the fuel for a gasoline vehicle with an energy efficiency of 22 miles per gallon costs about 15.9 cents per mile when gasoline costs $3.50 per gallon. Off peak rate of $0.03/kw x 32.9 kWh = $0.987/kg. Indeed this is Please read Google Privacy & Terms for more information about how you can control adserving and the information collected. 1) Fuels which consist of a mixture of several different compounds may vary in quality between seasons and markeds. It is a win in the low-coal places like California and the high-hydro and nuke places like Washington state. So the power company simply makes sure that for every kWh of power you use, they buy the same number of kWh from wind farms and other renewable sources. 1 kilometer per liter = 42.5 gallons per 100 miles * Energy contents are expressed as either High . However, if you're looking at the cost of a Nissan Leaf plus a 30A, 240V home charger vs a car with a gasoline engine and nothing more than a lead acid starting battery, and the projected energy costs over time, I think it turns out that the extra $5000 state tax credit tips the scales towards the Leaf being cheaper for a Californian who can't bring themself to consider a used car, and who can put up with the range restrictions of the Leaf, whereas with no state tax incentive, I think the economy gasoline car can be expected to be cheaper by a bit. Historically, when you increase manufacturing volumes by three orders of magnitude, that drives prices down, which might start to make this technology affordable directly to the utilities. The other is that, if you did grid-tie, you could be feeding that power into the grid, and thus reducing demand on grid power plants to burn fuel. LPG . The big question in many cases is "If I drive an electric car, will they burn more coal because of it?" A Tesla Roadster battery pack is 53 kwh. • One million Btu's is the heat equivalent of approximately 7 gallons of No. The price of an eGallon tells consumers how much it costs to drive an EV the same distance you could go on a gallon of unleaded gasoline in a similar car. You can target the Engineering ToolBox by using AdWords Managed Placements. The sulfur content of distillate fuels used for heating is regulated at the state level Fuel Energy content Price per gallon per million Btu … Access Doc. We can plug natural gas leaks (it just wasn't worth it from a financial standpoint but is worth it from a GHG standpoint.) Kerosene contains less lubricity than diesel fuel. Leaving out the issue of how much energy is needed to make the panels, there are some serious misconceptions here. A kilowatt hour is a unit of energy commonly used to measure electricity consumption. Mainly we generate heat from the chemical energy of the fuels, and turn that heat to electricity. Found inside – Page 44Gas from biomass residues now costs about $ 3.50 to $ 5.50 per gigajoule . ... Btu per gallon ) , while the energy content of gasoline is 35 megajoules per ... 1 gallon of diesel fuel or heating oil (with sulfur content less than 15 parts per million . probably the main thing in people's minds, since nobody is buying electric cars to save money right now, though they For those who really prefer an mpg type number, so that higher is better, you would do miles/kwh. 2 Finished motor gasoline sold at retail in the United States, including fuel ethanol content. There are about 30,000 calories in a gallon (about 4 liters) of gasoline, which is enough to power a person for about 20 days, depending on their caloric intake. I think the interesting question is what happens if the price of battery packs comes down to the point where the average automobile sold in the US has a 53 kwh battery pack, and we have approximately one automobile per person. From this, we can work out a national average number of 19.5 kwh in a gallon of gasoline, GHG based. (As a plus for coal, the plants are sometimes located further from people than highways are.). Electric cars mostly charge at night, which means they tend to use baseload power. 44 MJ/kg. I'd like to see cars come with some default setting of perhaps no more than 10% discharge at a time, and some limited number of such discharge cycles throughout the year (maybe 20-30), and some integration with when the owner expects to need the full capacity to inhibit discharging, and then let the free market and owners' judgment figure out what the optimal settings are, also allowing a car owner to set a minimum price on battery discharge (perhaps coupled with some maximum predicted price to recharge the battery after the discharging), and select more discharging than default, or turn off discharging entirely. The jury is still out on the cost of the battery as an "expendable" part of the car. I would hope we could cut that price but I don't see a win here. This would be equivalent to 11.26 gallons of propane. Refinery efficiency is about 90 percent and the energy content of a gallon of gasoline is about 132,000 Btu. For example, if the cost of diesel is $1.15 per litre and the cost of natural gas on an equivalent energy basis is $0.75 per DLE, the fuel savings are $0.40 per DLE. Energy needed to make 1 kg of H2 = 32.9 kWh/kg. Considered alternative fuels under the Energy Policy Act of 1992, CNG and LNG are sold in units of gasoline or diesel gallon equivalents (GGEs or DGEs) based on the energy content of a gallon of gasoline or diesel fuel. Self-Driving Teams Have Always Strived To Measure Safety. The EPA was not alone in this. Found inside – Page 36According to the Oak Ridge National Laboratory , gasoline has an energy content of 115,400 Btu per gallon ( lower heating value ) , and liquefied petroleum ... The main reason for the lower energy content (per litre) of LPG in comparison to gasoline is that it has a lower density. In the 3 states that still let you choose your power source, you can (and should) buy a greener one. You'll see in their math that they want to use the heat formula (real energy used) but then they have to multiply it by something called the "Fuel Content Factor." Wholesale Gasoline Price: The average wholesale gasoline price is the average of 13 unbranded and 13 branded wholesale prices at various wholesale fuel loading racks around the state. Found inside – Page 18... US gallon Gasoline heat content, BTU/US gallon Fuel tank capacity, MMBTU Energy storage, MJ 306 Range, miles 265 Miles per MJ 0.87 Miles per gallon ... Many people wonder about the very best power plant, which in fossil fuels would be a modern natural gas plant getting a bit over 50% of the energy out as electricity, if we could also get rid of the leaking. I'd be happy to see coal phased out, too. If everyone has a Tesla Roadster equivalent, that's about a three order of magnitude increase in production volume. Gasoline gallon equivalent (GGE) or gasoline-equivalent gallon (GEG) is the amount of an alternative fuel it takes to equal the energy content of one liquid gallon of gasoline.GGE allows consumers to compare the energy content of competing fuels against a commonly known fuel—gasoline. In the car it also heats the interior in winter and defrosts the windows. The typical American probably has a Nissan Leaf (~73 mile range) sized commute, but probably wants something closer to a Tesla Roadster ranged car (200+ miles) for the occasional road trip. It is the equivalent of using a kilojoule every second for an hour. products) is greater by between 5% (in the case of coal) and 10% (for natural gas), depend-ing mainly on the hydrogen content of the . And there are many answers to that question. The weight-density of gasoline is about 740 kg/m³ (6.175 lb/US gal; 7.416 lb/imp gal). Creative thinkers and investigators such as yourself can help save this planet! still burning when the exhaust valve opens and all of that energy escapes out the exhaust as heat and unburned hydrocarbons. Coal generated electricity has 2-3x time particulates of gasoline per mile driven and triple the acid-rain causing sulfur dioxide. A fair criticism, however, is "who cares about the heat released?" The Cape Wind and Deepwater Wind projects that have been proposed in New England are somewhere vaguely in the ballpark of double the cost per kilowatt hour of average grid generation. What I concluded in looking at this is you want to ask "why is somebody comparing the two?" Will wind power end up cheaper than coal? It was controversial, and I believe they were in error when they selected the theoretical number, giving a huge advantage to the electric cars in the contest. Most people will resist draining off their car at 3pm to deal with the peak load, because in 2 hours they plan to drive home, and probably don't want to start with a partial charge. how wrong the EPA's 99mpg number for the Nissan Leaf, 9,000 people die per year due to particulate pollution, my earlier post and the linked flash application, forcing another neighbour to cut down his redwood trees, Generate electricity from a gallon of gasoline, Yes, I think that's not the best approach, this is the most brain dead shit I have ever read. Lines and paragraphs break automatically. therm/foot³ to megajoule/meter³ (thm/ft³—MJ/m³) measurement units conversion. Our grid in Canada is several times cleaner, though in part that's because we're a big country with tons of hydro for a smaller population, and an advanced nuclear industry. No. If you get a variable price, that is the time to sell it, not store it. Greenhouse Gas emissions, g CO2 equivalent: 60 mpg-e(CO2), Allowed HTML tags:

1. . . If you don't connect your panels to the grid, it's very wasteful. If you are interested in information that you may not be aware of, and may have even in part dismissed when you ran across it (as many do) due to the context it may have been embedded in or whatnot, take a look at this: http://ufsolution.wixsite.com/unifiedfieldsolution . The heat is waste, except in cases where the power plants are urban and pipe their heat out to provide hot water and interior heating for buildings. It therefore has units of energy per length cubed or energy per mass. This is because higher-octane fuels allow for a higher compression ratio - this means less space in a cylinder on its combustion stroke, hence a higher cylinder temperature which improves efficiency according to Carnot's theorem, along with fewer wasted hydrocarbons (therefore less pollution and wasted energy), bringing higher power levels coupled with less pollution overall because of the greater efficiency. This page has been accessed 32,690 times. 1 gallon = 91,500 BTU 1 cubic foot = 2,500 BTU 1 pound = 21,500 BTU 4.24 lbs = 1 gallon 36.39 cubic feet = 1 gallon: Natural Gas: 1 cubic foot = 1,050 BTU: Gasoline: 1 pound = 19,000 BTU 1 gallon = 125,000 BTU 1 gallon = 6.1 lbs: Oils: 1 gallon kerosene = 135,000 BTU 1 gallon #2 oil = 138,500 BTU 1 gallon diesel = 139,200 BTU 1 gallon #6 oil . This would give us about 13kwh of storage capacity per capita, or enough battery capacity online at any given time to cover 8-9 hours of the grid's energy use. The DoE cites 588 grams CO2 per kwh as the national average -- I think the NG leakage number pushes it higher. The standard coefficient of gasoline's expansion/contraction equals 0.069 % per degree Fahrenheit. A cord of wood is a volume unit and does not take wood density or moisture . From 2017 to 2020, local and national prices for gasoline in July differed by 5.6 percent or less. Found inside – Page 74The energy content of natural gas is 0.04 kWh per gallon at atmospheric pressure (table 3.2). Compared with gasoline's 36.0 kWh per gallon, this is minute. • The heat content of one gallon of fuel oil roughly equals that of 41 kWh of electricity, 137 cubic feet of natural gas, 1.5 gallons of propane, 17.5 pounds of air-dried wood, 17 pounds of pellets, a gallon of kerosene, or 10 pounds of coal. What would the price of E85 (85% ethanol, 15% gasoline) have to be for its energy cost to be the same as that of pure gasoline? Lots more research is being done on calculating "grams of CO2 (or equivalent) per mile" as a way to compare electricity and gasoline. When there is nuclear, that gets used more for base load. This means that one gallon of gasoline has an energy equivalent of 33.4 kilowatt hours of electricity. Yes, they are local to the power load but the transmission losses are only in the range of 7%, and the battery is less efficient than that. One reason to compare gasoline and kwh is to find out the cost of driving. Energy content per kilogram is higher than for gasoline (higher hydrogen to carbon ratio). It's why they plugged in If their trip home is short they might go for it, as non-commute cars might. 5 This conversion is an estimate. Energy Source Unit Energy Content (Btu)Electricity: 1 Kilowatt-hour: 3412: Butane: 1 Cubic Foot (cu.ft.) Question: Diesel Engines Give More Miles Per Gallon Than Gasoline Engines, But Some Of This Is Due To The Higher Energy Content Of Diesel Fuel. Gas Cost: We spent $124.66 for gasoline for the trip. I keep wondering when the government (various!) In fact, the average person going about 15 miles per hour (about 25 kph) on a bike could get more than 900 miles per gallon (almost 400 kpl . http://www.theatlantic.com/business/archive/2011/01/how-oil-could-kill-the-recovery/68933/ notes that the US imported about $400 billion of oil in 2008; the numbers at http://www.census.gov/foreign-trade/balance/c0015.html suggest that if we could stop importing oil, that might correct at least half of our trade deficit (although if we import lots of lithium and other battery materials initially, the initial effect on the trade balance may not be so strong). Found inside – Page 196... 0.80 per gallon less than gasoline at the wholesale level , but then the paper argues that ethanol prices are “ well above ” the cost of gasoline . Miles per gallon gasoline equivalent (MPGe or MPG ge) is a measure of the average distance traveled per unit of energy consumed.MPGe is used by the United States Environmental Protection Agency (EPA) to compare energy consumption of alternative fuel vehicles, plug-in electric vehicles and other advanced technology vehicles with the energy consumption of conventional internal combustion . The content of this field is kept private and will not be shown publicly. Not even remotely close. That so much oil comes from far away is troublesome. In California, the tier system makes heavy users pay 32 cents/kwh, which would make the electric cars more expensive than gasoline, but I believe that there is a special law which lets owners of electric cars avoid the tier system and pay a more basic rate. Each mile you drive will burn the fuel of the grid, and you can't get away from it. Kerosene has an average BTU content of approximately 133,500 per gallon and diesel fuel has an average BTU content of approximately 139,500 per gallon. Now according to the laws of quantum mechanics all electrons are totally identical and it's impossible to tell whether any particular electron feeding into your car was pushed by a turbine generator spun by coal-fired steam or one spun by solar-heated steam or was pushed by a generator driven directly by wind. This method is also pure in that it deals with the real energy being released, either by burning gasoline, or coal, or natural gas, or "burning" nuclear fuel. They also have lower sulfur content and fewer contaminants. Found insideThis text, by a leading authority in the field, presents a fundamental and factual development of the science and engineering underlying the design of combustion engines and turbines. At present, nuclear power and hydro don't emit much pollution at all, but people are very divided on how green they are. Found inside – Page 418For the purpose of comparison, we use a density of 0.75 kg/ L, or 2.84 kg/ gallon. An average gallon of gasoline has an energy content of 33.4 kWh, ... Economics questions and answers. Ethanol contains about one-third less energy than gasoline. Ethanol free gasoline costs about 25 cents more per gallon here in South Carolina- $3.72 per gal . Cookies are only used in the browser to improve user experience. still burning when the exhaust valve opens and all of that energy escapes out the exhaust as heat and unburned hydrocarbons. Also the solid fuels will have a similar quality variation for the different classes of fuel. We don't save this data. That means a gallon of gas contains the energy density to power your television for 36 straight days - in a comparatively tiny package. It seems to me that we should compare the number of kWh that an electric generator could generate from a gallon of gasoline. The refreshed 2017 model year Fusion Energi has an increased EPA rated fuel economy in all-electric mode to 97 miles per gallon gasoline equivalent (MPG-e) (2.4 L/100 km) for combined city/highway driving, with an energy consumption of 35 kWh/100 mi. This book will also have much to offer to industry leaders, investors, environmentalists, and others looking for a practical diagnosis of energy efficiency possibilities. 3 Distillate fuel with 15 parts per million (ppm) suflur or less sulfur content. I believe the local power companies should all publish these numbers on their web sites and on your power bill. And electricity — at 3,412 BTUs per kwh and assuming an average price of 11 cents per kwh — comes to around $32.25 per mmBTU. It would be silly, but you could even imagine burning gasoline in power plants (and some power plants do burn oil distillates) to make the comparison more direct. You will also see well-to-wheels numbers for gasoline around 11.5 kg of CO2 per gallon. At Highway Speeds, It Takes 0.20 MJ To Move An Aerodynamic Car 1.0 Km.
