 Zero-point energy

How about zero-point energy and other methods of quantum energy extraction?
It exists, and it's been proven to work. Mainstream science just hasn't accepted it yet.

"Mainstream science just hasn't accepted it yet."

Muhaha, another crank person :-D

Vacuum isn't empty (there are pairs of virtual particles-antiparticles, vacuum is fluctuating), you can see it for example in Casimir effect, but you can't drain energy from it. Maybe in some far far future we will find some way how to use Zero-Point-Energy, but now it looks really impossible and it will surely be impossible in near-term future. Those who claim that they invented some "vacuum energy" devices are crackpots, sorry...

 Nuclear

Score 50%

Unless the efficiency of the solar panels improves dramatically, I wouldn't even consider them. A solar panel requires more energy to be built than the energy it's able to produce for its whole lifetime, so the energy is going to come indirectly from the petrol anyway.

In the list it doesn't appear the wind energy. I think it's more feasible than the solar energy since it really produces more energy than the generators need to be built and a field of generators can produce a reasonable amount of energy.

Fusion energy still needs a lot of research and cannot be seriously taken into consideration yet. Of course, it deserves farther research and will have practical use in the future but we can not think on relying on it yet.

So I voted nuclear energy. I also don't like nuclear power stations but at least they work NOW and they are cleaner than petrol. Yes, you still have the nuclear waste but they're researching methods to reduce the half life of the nuclear waste and they could be stored somewhere, it's not like with the CO2 which goes to the atmosphere increasing the greenhouse effect.

Anyway I think it's obvious there won't be ONE main power source for the future but a combination of different ones, like now.

wrong. into the corner of shame with u.

http://en.wikipedia.org/wiki/Net_energy_gain

after 2 to 5 years todays solarpanels produced the same amount of energie that was needed to build them, while having a life span of 20 to 30 years,

http://en.wikipedia.org/wiki/Solar_panel

speaks even of 40+ years. maybe you should buy your solar panels else where :)

Then I was bad informed. I read it in a report of crisisenergetica.org, a spanish website dedicated to the energy crisis and the possible solutions to it. If the NEG of solar panels is now positive then it's cool to hear it. :) Anyway the NEG of the wind power is higher, right? Then it might be a better solution anyway. Although I wouldn't discard any alternative as long as it's renewable, of course.

Well, this is a poll about the energy of the future, after all, so fusion could be considered, even if it isn't available today.

And technically, fusion would fall under the catagory of nuclear, although I assume that the poll option is refering to fission.

wind? at my place it seems the energy firms can't get enough of those windmill-like towers.

Well, wind energy is a great idea, however the amount of turbines that would need to be built if we wanted wind to solely power a single city the size of Sydney would be quite outrageous, so I don't think it's efficient enough to replace our current forms of generating electricity completely, but it's wonderful as a secondary source. Solar power is definately proving itself to be efficient enough to become the main source of electricity for the future, it certainly is clean and environmentally friendly.



However, I did take the blue pill, so my vote goes with the humans. Now come with me, I need to plug you in to my laptop. I'm only on 30% battery.

 solar energy

Some scientists say that is sufficient an area of 500 square kilometers of sahara desert to supply the energy of entire world.
Let's put solar panel then!
In deserts rain rarely!

The problem is the transport of this energy in all world.

But there are deserts also in the other continents (europe exclused).
-----------------
Someone know something about the ELIOS3 fuel
I listen that some thousand of litres can supply energy for a year for a continent.
It is true?

I also heard that the shadows of the solar panel could be used to grow some plants below the panels.

But I guess that the wealthy countries do no really want the third world countries to become more and more powerful. They make good money from the poorer countries :-(

 I voted for solar

- Germany has on average 50% of the sun intensity of the Sahara (per square meter)
- 3000 square meters should be enough to supply the needed energy for Germany.
- We have about 2800 square meters of flat roofs
- solar installations are recycleable

I guess you mean square KILO metres.

;-)

If 3000 square metres would be enough for whole Germany, this poll would be useless as the answer is obvious in that case.

How do you like Plasma 5?
 The best KDE Desktop ever.
 Definitely a nice improvement.
 Not decided yet. Haven't tried it yet.
 I do not like some of the changes.
 KDE is taking the wrong way.
 I am still sticking with KDE 3.5.
 I have no opinion, but wanted to vote anyway.
