What will replace oil?

9 Answers
While we are still discovering new sources of oil, what will replace oil when we have used up the supply?

Oil is primarily attractive due to its inherent energy density, that is, it carries a high amount of energy per volume unit. In addition, the long molecular chains can also be used to manufacture all kinds of other synthetic products, with different kinds of plastics being one of the primary products, but also various chemicals are based on crude oil.

From the perspective of energy density, I am not sure that there are much alternatives. The replacement here will probably be synthetic or renewable petroleum and diesel, made from vegetable oil, for example. While natural gas and hydrogen are good, they are still much more tricky to handle due to their volatile nature as compared to oil. Similarly, for production of synthetic products, we will also have to rely on synthetic-based vegetable oils.

In any case though, the importance here is that we should reach a point where the energy density is of no concern through the use of more efficient vehicles. If this becomes good enough, then very likely batteries and fuel cells will be viable alternatives. As of now though, the energy density is too low and the costs are too high.

It is remarkable to me that there has been one unmistakable sign after another warning all of us that we are consuming too many energy resources at a pace that is simply not sustainable. There will need to be a unified global effort because current resources will otherwise go to the highest bidder.

Solar and wind energy would seem to be the obvious choices to combat this dangerous spiral, but the lobbyists for their "competition" seem to be employing endless financial resources to make them go away. In addition to replacing oil, we also need to find practical replacements for politicians and lobbyists intent on pursuing a "win at all costs" strategy.

Initially natural gas is what is replacing oil. It would be in full use if it were not so hard to store. It is now burned off at almost every oil well at some point in it's life. Pipelines are growing more and more to capture the natural gas. The prices of all fuels will jostle up and down as time goes on so uses of all fuels will fluctuate as a replacement of oil.

Ultimately oil will decrease as other sources of energy become more cost effective. ultimately fusion energy will take over when the process is rendered practical. Along the way thorium reactors will be phased in over other nuclear power since it is much cleaner and safer.

It will take a broad spectrum of products to replace oil. The energy density problem will have to be solved by electric vehicles. We will burn massive amounts of solid fuel at power stations to create a practical mobile source of energy (electricity). The other oil derived products, such as plastics will have to skyrocket in price so that other products become competitive and fill the void that oil is filling now.

This is a tough question, and to be honest I don't know what can replace oil.
If the oil ever run out we screwed, to but it nicely. Remember oil isn't only for producing energy.
oil is used to manufacture plastic, Rubber, petroleum jelly, and a wide range of lubricates.
Even your Keyboard was created from plastic that originally can from oil.

There are many resources available, however none of the natural resources in this world such as wind, solar, etc will ever compare to the energy output oil gives out.

Other solutions will probably be nuclear power or an overall revamp of how we use our resources

Hope I helped.

Have you ever seen recycled oil in the automotive department? I personally avoid it like the plague, since someone told me that all they ever do is clean up the oil and put additives in it before reselling it. If the oil was used, I won't buy it, period.

Oil will have to be replaced with renewable sources of energy such as solar and wind.

Nuclear fusion would be another candidate if they manage to solve the issues with the technology.

There are also other sources such as bio diesel.

Oil will not be replaced until the resource is completely unavailable. When that time comes, electricity, solar, wind, and hydroelectric sources of energy will be used.
