How much energy does it take to make 1 gallon of gasoline?

[uscitizen]

One must include drilling energy, pumping, and transport from foreign sources if we are going to compare it to ethanol production which is my intent.
Refining energy must also be included. But not domestic transport since that is needed for ethanol as well.

 

[uscitizen]

And if we want to compare costs of gas vs ethanol there will be no comparison since we have spent trillions defending oil in the ME. Not counting hundreds of billions in other forms of govt subsidies to oil security/production.

A lot more than it did when crude was seeping out of the ground in Pennsylvania. One day after all the low hanging fruit is plucked, it will exceed the energy you get from burning a gallon of gasoline, and that will herald the end of the oil age.

I am not so sure that the production does not already consume more than 100% of yield in producing gasoline.

I am not so sure that the production does not already consume more than 100% of yield in producing gasoline.

Virtually all of the energy used to produce gasoline is supplied by fuel that is a byproduct of the refining process. Diesel fuel runs generators and pumps. According to Wiki, about 46% of a barrel of crude is sold as gasoline. Seeing that oil companies also sell diesel, heavy fuel oil, tar for road surfaces and oil for lubrication, as well as byproducts used to make plastics, it would seem to me that there must be more energy produced than consumed.

the refineries consume tremendous amounts of energy.
the tankers burn large amounts of bunker oil/diesel.
The drilling rigs take energy.

Why is the amojunt of energy to make ethanol readially available and not easy to find for Gasoline?
the liberal media?

The energy consumed is 17% of the useable energy in the resulting fuel

EIA Energy Kids - Oil (petroleum)

A 42-U.S. gallon barrel of crude oil provides slightly more than 44 gallons of petroleum products. This gain from processing the crude oil is similar to what happens to popcorn, which gets bigger after it's popped. The gain from processing is more than 6%.

One barrel of crude oil, when refined, produces about 19 gallons of finished motor gasoline, and 10 gallons of diesel, as well as other petroleum products. Most petroleum products are used to produce energy. For instance, many people across the United States use propane to heat their homes.

Kind of like asking how much coal the Chevy volt will be burning to drive on the street

Ok that is in the refining process.
How about the transport form overseas for that portion, the drilling, the pumping, etc.

Just want ing to figure it the same way some do for ethanol production.
domestic transport after refining shoudl not count as it is the same for all fuel products.

1.5 gal diesel to make 1 gal ethanol.

And this is straight from Citgo corp.

I installed all the electrical controls to blend ethanol at the loading rack,and had a long talk one day with Citgos head engineer while doing the job.

they should use biodiesel.

In comparing energy sources you can't just go by the energy to produce vs. the energy availible. The issues of "density, portablility, and reliability also come up. Density is how much energy you get out of it per unit volume, which is why gasoline is better for a car than say wood. Portability is related to density, as well as how easy it is to transfer from storage to use. This is why liquid gasoline is superior to say a solid form, like high quality coal for automotive use. Finally is reliability. This is where the ICE using gas or diesel beats out things like electrics, or solar powered cars. This includes the infrastructure required to keep you supplied with said fuel.

The issue with ethanol or biodiesel, is that unless we figure out a way to make it out of waste products, you have to grow something to make it. That needs land, lead time, and once this is done, basically similar refining techniques to make it into a fuel. I'm not dismissing ethanol/biodiesel out of hand, just worrying that the amount of land required to grow enough corn/algae/PLANT X to supplant gasoline would not be feasible.

Maybe ending the oil subsidies will effect this number?

So gas can go from $4.00 a gallon to $6.00 a gallon?

 

[Truthmatters]

whats the differance we already pay that in subsidies

 

[martybegan]

whats the differance we already pay that in subsidies

Like any tax based expenditure, the true cost is hidden. Also it is spread out, and thus is probably less in taxes than the effect you would see at the pump.

Add in the fact that it is a commodity and traded, any increase would have a ripple effect via speculation and hedging by refiners/users.

Or to scale it, the subsidies (really tax breaks) amount to $4 billion a year. assuming 300M americans, thats a total of $13.33 per person. Big savings there.

Hell lets cut the number in 1/2 to represent taxpayers. You are now up to $26.66 saved per person cutting this, without knowing how it would increase costs later on.

But keep going after the lefts favorite boogeyman. OOOGA BOOOGA.

Not much difference,still takes more to make less??

I am doing a paper on how much electricity that it takes to produce one gallon of gasoline from exploration to the gas station. If anyone has any helpful links to for this I would greatly appreciate it. Thanks..!

You will have to keep in mind however, that there are different types of energies that are being used in the input, and this in order to create the precise energy that becomes the final product as the output, all in which is desired by us to fuel the economic engine that moves the economy in which we all depend on. Now nothing so far beats the results found in gasoline and diesel at the end of the chain, in which powers the economy in ways that no other energy can. So the final product is the most important here, because it determins the power that is found behind the engine that drives a strong economy all because of.

Example: Can an electric car do what a gasoline driven car can do, as far as endurance and power goes to get the ultimate job done ? No it cannot, but the electric car could perform well upon a grid or within an enviroment that is designed to work best for the electric car and it's owner. Otherwise it is more economical to operate an electric car within a city or community where conditions are just right in application of, in which suits the car to be at it's best in those conditions, but outside of that grid, the electric car as does other alternative methods of transportation fails against the gasoline and diesel driven vehicles. These are vehicles that need long standing endurance and power to get the job done. It matters not about the different types of energies that are being used to get to the final gold that is found in the final product, just as long as the final product is as good as we expect when we began the journey towards that final product in which is as good as gold in the end when we are finished with it.

This is my thoughts on the matter, but help me tweak my analysis if I am way off course here.
