Do we have any alternative(with efiiciency) if fuel got empty in this world?

Answer 1

First of all, fuel IS getting empty, oil anyway. We will reach peak oil in a couple years and after that, oil will become more and more difficult to extract from the ground. Sure, we will always have some oil, but eventually it will become costlier than its worth. (If it takes a barrel of oil to extract a barrel of oil, it ain't really worth it).

As far as alternative fuel is concerned, we have none that will equal the energy output and efficiency of oil. No alternative source can supply today's energy demand. I'm sorry but you can't sustain the energy needs of 6.5 billion people with solar panels and wind turbines. The idea of the "hydrogen economy" is also a joke. The bottom line is this: Hydrogen is not an energy source, but is instead an energy carrier. To derive free hydrogen we must break the hydrogen bond in molecules. Basic chemistry tells us that it requires more energy to break a hydrogen bond than to form one.

Nuclear power has the same problem that oil does in that it is a finite resource. Nuclear energy relies on uranium, and uranium will be depleted on Earth in probably less than 50 years (and that's if the current trend continues, not if a crapload more nuclear power plants are built, in which case uranium deposits will be depleted earlier.)

Nuclear fusion will never be a viable energy source. While it potentially could be a clean and sustainable energy source (it does not require uranium), there are many engineering problems that have not been overcome and probably never will be.

So oil and nuclear energy will be out of the question soon, and no other energy source can compete with it. What does this mean for us? Collapse. Industrial civilization will cease to exist after the oil crash because it is inherently unsustainable and really, should never have come in to being anyway. I for one look forward to a new way of life, free of the harm industrial civilization does to us and ready to live a more natural and sustainable life, the way we were meant to.

The party's over, folks.

Answer 2

I'm guessing you probably meant "fossil" fuel . To that, the answer is yes.

Fossil Fuels are still the most widely used fuels for *one* reason: they're cheap as hell. This is due to availability, infrastructure (we've been using them for over 100 years, the equipment is already in place and we're actually fairly efficient with it), and if you're a conspiracy theorist: massive collusion between energy companies.

There are many other sources of renewable fuel that are quite viable, but they cost more. Sometimes only slightly more, but when you're dealing in billions of tons/year, a cost of a few cents per ton can mean millions of dollars for companies

Once availability of fossil fuels decreases to a certain point the cost will go up, and (cheaper) alternative fuels will become more prominant.

Similarly, if any of these alternative fuels make advances that make them cheaper to implement than fossil fuels they will come to prominance even before fossil fuel supplies dwindle down to nothing.

To some extent, these factors are already occuring. Many power plants and other industries have been replacing coal with petroleum coke for the last 5 years or so as the price of coal has risen. Unfortunately this is somewhat of a fossil fuel since it's a waste product of oil refination, but it's a step in the right direction.

Answer 3

I personally live "off the grid" and use solar and wind power to generate my electricity.
Water comes from my own well, the pump for which is also solar-driven.
I currently heat with wood but am working on passive solar-dependent heat sources.
Same goes for my current use of Propane which I hope to replace with passive solar implements.
I am looking into thermal mass building materials such as papercrete, alternate energy sources such as hydrogen generators and the like.
The thorn in my side is my truck which uses gas. Not sure if in this life time I'll find another source of transportation (I have a horse, but riding her 15 miles to the grocery store is as of yet prohibitive).
We could ALL have alternative energy sources to power our vehicles IF there were no governmental restrictions to the release of the technology.

Answer 4

Don't worry, the only reason we are still using oil is because the oil companies don't allow all the MANY alternatives to jump in the business. We have natural alternatives like the solid hydrogen in the bottom of the sea, or also chemical ways like nuclear fusion. No worries.

Answer 5

Yes. There have always been alternative energy sources. Wind power is one. They were never fully developed because they weren't as lucrative to handful of people who now control the oil.

Oil while a finite resource, is in no immediate danger of becoming obsolete. Countries, including the United States, sit on huge oil reserves. Oil supplies to the public are manipulated to maximize profits, not because it is scarce.

Answer 6

i'd like to see hydrogen fuel cells take off...or else good ole electric...

Answer 7

solar, wind , wave, geothermal and biomass energy are all renewable resources. they are not so widely used though. not sure why.

Answer 8

i was thinking maybe we could use urine. sorry its just a thought
