how many time will past until non conventional energy (non hydrocarbons)?

We already use nuclear power...so none.

Yes, actually it will. well, not really run out of oil but obtainable oil.  It is estimated that drillable oil reserves could be extinguished within 50 years given present usage and the estimation of future usage.

Here is the basic information including some alchemy (second two references).  Carbon is so old in human time that its history will never really be known.

It will happen someday. I dissagree casually with the people who said it will never happen. I believe once we have a cheaper energy source, and faster travel, we will do it. \n\nWe have the technology today, but it's the cost, the danger, and the time that prevents us. \n\nIt will happen someday, I have no idea when, but it will. I wouldn't hold your breath though.

it is a very important question and it return to future .we know  that in future all types of energy as oil will finish and nuclear energy will instead to other energy .and some country that are holder of this type of energy doesn't like other country can produce nuclear energy and will be dependent to them  .

Wonderful question really.  "When will the Earth's fossil fuels run out?"  I have heard different estimates including in a few a decades, to a century.  Doesn't really matter now though does it. JESUS will return someday soon.  That is in the Bible.  That message was warned us from JESUS HIMSELF. Yet, in the here and now, if one wants a stable society without pandering to terrorists, supplying them with the money to build the bombs they want to use to destroy us, we need to end our dependency on foreign oil.  The only solution then is alternative renewable energy.  Solar Power, Batteries, Hydrogen, Fuel Cell technology.  Solutions such as Ethanol and Fuel additives are partial solutions which require often flexible engines that can use such fuels.  And it requires that we get oil tycoons, who have a vested monetary interest in current oil reserves to invest in and promote these technologies with incentives and the promise of future profits on their investments.  Yet, repent and prepare for the return of JESUS CHRIST, because he may return any day now.  Even today, be ready, everyday for that eventuality.  \n\n-LOVE YOUR NIEGHBOR AS YOURSELF

I'd be sceptical about the existence of such civilisations as we don't have any substantive evidence to suggest that they existed although it's not completely beyond the bounds of possibility that some such civilisation existed at some time.\n\nAn interesting thought however is this: what if through some catastrophe, our present (or near future) civilisation was set back thousands of years - we'd have to start all over again wouldn't we?  We might do fine until the equivalent of our own industrial revolution of the 17th-20th centuries.  But this second time around we wouldn't have anything like the same ready access to fossil fuels because we exhausted them first time around ie during the 17th-21st centuries.  Would we manage an industrial revolution based on renewables - maybe we would.  If not maybe we would not be able to achieve a complex industrial society and then post-industrial society and might stay locked into a lower-tech way of doing things - for better or for worse depending on your outlook.

It shouldn't...at least not in 2020.  There are enough oil supplies to last till 2050.  And we're still finding new oil fields.

Certainly not the bunch of oil-money sucking goofs in Washington, D.C.  (and I'm talking about both sides of the aisle, for those of you who still believe there's a difference).\n\nGood old ingenuity will do it, and enough people are sick of the status quo that I think it will happen within the next 5 years.  I see a lot of people talking about electricity for cars in Y answers--forget it.  Batteries too heavy, most electricity still produced using fossil fuels.  "Hybrids" are smoke and mirrors--still rely on fossil fuels.  My question would be, "Which intelligent people out there are smart enough to buck the system and introduce some new, truly alternative energy sources, not to the hide-bound corporate types and the politicians, but to the average Joes and Janes in this country who would like real options?"

I personally believe that oil is renewing itself daily at a rate equal to or greater than our current consumption rate; thus it'll last as long as there are plants and animals to die and decay.\n\nBear in mind, this is only my opinion.

It is estimated that the point of no return is about 10 years.\nOh yeah it's not "saving the planet" but keeping the climate stable for life as we have enjoyed  it for the past 100k years.

I agree with you, unfortunately the oil industry has a lot of money and well you know how that goes. Currently there are several research and development programs going on relating to alternative energy sources. Examples are Methane, ethanol, and hydrogen.  Keep you fingers crossed that one of these experimental energy resources hits pay dirt.

It's timely that you ask this question - I am currently reading the book, "The End of Oil," which addresses this very issue.  I've only just begun the book, but it looks like we have another 30 years before the oil supply will start seeing a sharp decrease.  The fall in the oil supply will coincide with an increase in demand for energy, which spells TROUBLE.  Hopefully within 30 years time our brilliant engineers and scientists will have come up with a solution to the volatile and dangerous nature of hydrogen...

lol just looking at some of the answers 2030 isn't that far away most of us will still be alive (i hope i am) unless of cause there is a big nuclear war which wipes out the whole world.. If not it wont be much different to what it is now.. most vehicles will be run on an alternate fuel source such as electricity or methanol.. but there is no way we will have big hands,robots and flying cars.. i know technology is moving fast but not that fast

~I assume somewhere in this drivel you actually think you posted a question.  Sorry I was to ignorant to figure out what it was.  Maybe you should consider going back to school to learn how to speak and write in intelligible English.  As to to concept of oil being a renewable resource, of course it is.  It just might take a few million years for the ferns to grow, decompose and transmogrify.  What the hey, Sequoias are renewable too.
