A question- How big is US Energy Sector?

Unread postby donshan » Mon 24 Oct 2005, 02:31:34

I have only been on this forum a short time, but note there are many experts here who have access to a lots of data. I would appreciate your expertise in helping me find some economics data on the US Energy sector.

I read a few weeks ago in some publication the statement that went something like this:
$this->bbcode_second_pass_quote('', ' ')The US Energy Sector is only 5% of GDP, but try running the other 95% without it"


I have tried to find the article again without success. Darn, should have bookmarked it :(

I then attempted to Google search to find US GDP statistics like this and found lots of data, but none of it exactly in the form of the fraction of the US GDP that is devoted to energy.

Is this statement I quoted true?
Where could I find a reliable reference?

Are statistics like this of the breakdown of various sectors of the US Economy available on the Internet?

Thanks in advance for any info or comments on this quote

Best I could find:

Gives energy expenditures and GDP per year.

Hope that helps.

I am very interested for a fuller picture myself. I suspect it is much like agriculture where less than 5% of the population are involved in agriculture directly, but many more work in secondary & tertiary industries directly related to agriculture.

If those figures from the DOE are correct then energy purchases make up between 5-10% of GDP, but again I would like to know the total workforce involved in the energy business - research, development, extraction, refining, transport, distribution, etc? I once read that the energy industry was the largest sector of the economy, but I am also frustrated not to be able to find hard numbers?

Thanks for the link. :)

I think statements like that are misleading. True, energy and agriculture may be fairly small portions of the economy, but without either of them the rest of the economy would grind to a halt.

$this->bbcode_second_pass_quote('Doly', 'I') think statements like that are misleading. True, energy and agriculture may be fairly small portions of the economy, but without either of them the rest of the economy would grind to a halt.



Which statements?

Thanks very much. It does help. It appears that energy sector near 10% may be a better number, and as MrBill notes it is not clear if all the related parts are in the EIA numbers. For example, the contribution of running gas station businesses. :-D

Like the quote I saw and posts added so far indicate, the US economy would grind to a halt without the energy sector. I have always tried to quantify issues.

For example, It is easy for some to to say that solar power alone could solve our energy needs until you do the math on how much it would take. I am still working on an estimate of how much solar power it would take, to produce the hydrogen it would take, to replace 8.8 million barrels of gasoline use a day using hydrogen fueled vehicles. The initial "ball park" is around 10,000 sq. miles of solar arrays, but I am still checking for errors and methods of the calculation. There was a paper in Nature, that also did this calculation and came up with 1000 nuclear plants needed to fuel the US transportation with hydrogen.

The related question then becomes," what fraction of US GDP would be needed to build and run a new renewable/nuclear energy infrastructure for a "hydrogen economy" on this scale, and how does that compare with doing it with fossil fuels as we do it today?"

Without electricity you can't buy a gallon of milk today, because the cash registers are down, or fill up you gas tank, or run the furnace in your home, and milk, gas, and heating fuel have their own energy inputs to get them produced and delivered to market.

take away refridgeration and there goes a lot of our agricultural surplus.... we'll be eating rolled oats instead of diary and meat products for sure :!:

Without electricity you roll the oats by hand, or mule. Then the calculation becomes," do you get enough calories to eat, out of the rolled oats you make for the muscle power to turn the roller?"

It goes on and on!
