What will be the primary source of energy when oil & fossil fuel resources deplete?

Question

I'm doing a school project on the above question. I need some sources and opinions, and welcome yours! Thanks!

Answer 1

bio energy,sun and wind and of course hydrogen (water)

Answer 2

A lot of people have posted hydrogen, but this is somewhat unlikely. The amount of energy it takes to cause fusion is enormous, though the resultant energy is basically unfathomable. The molecules must be heated to such an extent that the attractive forces between the individual parts of the atoms are overcome by the heat, basically causing the atoms to disassociate and regroup as helium. While this reaction does release a lot of energy (i.e. the sun), it requires huge amounts of energy to initiate the process. The sheer fact is, at this point in time, fusion is just not an option; we do not have the ability to reach the temperature levels need to cause fusion.

As for hydrogen burning, it produces water. The problem: getting hydrogen. To refine hydrogen, the best and most plentiful source would be: water. The energy required to refine hydrogen from water and the energy released by burning hydrogen to produce water is equivalent (see the 1st Law of Thermodynamics).

The main point is that at this time, we don't have an exact answer, otherwise we currently wouldn't have a problem. All we really have are ideas: wind, solar, and other renewable sources (i.e. ethanol from corn and other plants).

Answer 3

When u think we will run out of fossil fuels? I have an answer u need to think on . Would it be never,the earth is continually recycled,and here is how. The that terrible CO2 that the plants recycle into oxygen. in that process there is also another branch where the CO2 in the plants that produce wood ,leaves etc. which is washed down the river to the delta where It starts to change to gas,oil,and after a long time coal. The earth has been recycling this for a million years.

Answer 4

We already have all the technology we need to replace fossil fuels. These have already been mentioned: wind, solar, hydrogen, biofuel, geothermal, etc. Each has their own pros and cons, but are always improving, and the fact remains that right now, we could probably support 80-90% of our fuel needs through various renewable resources. The reason we're not? Oil companies are the hugest corporations in the world and their stranglehold on markets and governments is staggering.

Answer 5

Fossil fuels are chemical ability fuels that are saved below the earth. on account that they take 1000's and tens of millions of years to make, there's a constrained furnish. Our use of the fuels fantastically outstrips the manufacturing of those fuels below the floor of the Earth. they're particularly helpful fuels. The fuels could be extracted, shipped to turbines, and then used. particularly, they're short term extra fee-effective, yet long-term extra costly. Renewable ability components have a plenty shorter duplicate time. there is considered to be an endless source of ability. The components are weaker, yet extra sustainable. The 'gas' for those ability components occurs certainly. particularly, they're short term extra costly, yet long-term extra fee-effective.

Answer 6

Oil and fossil fuels won't deplete for hundreds of years. I would say the technology for their replacement hasn't been invented yet.

Difficult to say what technology will be available in a couple hundred years.

Answer 7

Nuclear

Answer 8

Exhaust fumes from Hummers!

Answer 9

renewable energy and non conventional energy like
1.solar energy
2.wind energy
3.geo thermal energy
4.nuclear energy
5.wave energy
and so on

Answer 10

biomass, heat exchangers, hydrogen, windmills, nuclear, solar

We have about another 50 years till supplies get low I think.

Its mostly cost driven.
