Best method of green energy

Being interested in green energy, I was wondering what some favorites were out there. Not the most efficient or practical (necessarily), but simply the *BEST*.

personally, I think that using piezoelectric energy from dancing in order to power the dances lights and air-conditioning is both clever and awesome.

Its weak, breathing only does so much work but its cool.

yeah i mean, it may only be 50 mw but the concept is interesting

Cut the human population in half, thus reducing the world's energy consumption by one half. Then take all the dead people and use them as fertilizer for plants and trees. That's about as green as it get folks ;)

except for all of the CO2 released by decomposing human bodies. Other than that I see no problem with it :D

no, not so much of CO2 will be released once we kill as many as half the population and use it as manure and fertilizers for the plants. it will even help the vultures feed on some good and tasty meat. actually come to think of it, if we kill fatties more than thin ones, then that will help more better. also we can try becoming veggies for a short period of time, so that species that are going endangered, will have some time to recover from the shock of being the least in numbers.

Depends what you mean by "best" if it's most efficient then it's bioethanol. If you mean cheapest them it's solar. If you mean easiest then it's Wind turbines and if you mean best potential then it's ocean tides.

The most efficient form of Energy known today is Actually Gasoline. The most efficient Heat energy-mechanical work converter known today works at 65-67% efficiency. Bioethanol actually has a -12% energy Efficiency rate. The Cheapest form of Green Energy is Nuclear Fission, almost by definition. The easiest to make form of Green Energy generators is Thermo-Solar, it can be as cheap as $300 to cover a small roof. The one with the best potential is actually Zero-Point Energy Manipulator Generators, as they quite literally suck energy out of "empty" Space and are powered by the gravity of all mass in the universe. As of today, Id say the Best form of Green energy is Nuclear Fission, thanks to its low cost and high energy output.

"Zero-Point Energy Manipulator Generators"

there is no such thing as an energy manipulator generator. Something cannot be both manipulated and generated instantaneously.

secondly, zero-point energy (if it even exists) is theorized to be energy in its absolute lowest form. Entropy dictates that we cannot convert energy from a lower state to a higher state, so converting the absolute lowest state of energy to anything useful would violate the laws of physics.

"Nuclear Fission" is absolutely not 'green'. In addition to literally being bad for the environment due to the dumping of radioactive wastes into the earth, they are in no way low cost. They may be efficient once set up, but the costs for building the plant are around $4000/kWe

whereas wind power is around $1821/kW.

where exactly did you find this information? You state each of these quite factually, without giving neither explanation nor source.

For the majority of these topics- although I am knowledgeable in them- I do not know the exact efficiency or cost/ kilowatt and so would like to know.

what I am more concerned with is what you mean by 'easiest' and 'most potential'. For instance, piezoelectricity could be harnessed from everyday actions like walking, driving, etc.

And I do not even know where to begin with "most potential". How did you even come up with criteria for 'most potential'?

Consider matter-antimatter annihilation. Should we develop an easier mechanism to capture it, we could convert 1 kilogram of antimatter and matter into 8.988×10^10 joules in a fraction of a second.

for comparison, the maximum yield of kinetic energy from the ocean's waves are about 2.88×10^20 J/year.

That would only require 3204 kilograms of antimatter. As of now, that would not be feasible- but that is a far higher energy density than anything else in the known universe. Were we able to harvest it from the Earth's Van Allen belt, it would have a lot of "potential"

Piezoelectricity is a very neat topic, especially under Highways and high-traffic-volume streets. However, as of now, most generators have only a 20% efficiency and a high input cost, and due to the nature of their placement, roads and highways, it would require a huge government bill to put these in. If they can achieve a much higher efficiency, around 60%, Id say that they should and would be put into every Highway. Until then, the easiest form of green energy remains thermo-solar.

As for Most potential, you give the example of a Matter-Antimatter Anihilation Generator. Yes, it gives off a great amount of energy per kilogram, but the cost of infrastructure and a stable reaction chamber would be in the trillions per facility and the cost of fuel would be enormous, regardless of its source. Unless we can get Zero-Point Energy manipulators in here, there is no way to efficiently transport, hold or utilize Antimatter. My suggestion would be a Zero-Point Energy Manipulator Generator. By utilizing the gravity of any mass at all, useful energy is produced. Essentially, the Earth's Own Gravity could be used, or the gravity of every single body of mass in the universe. Endlessly, as well.

Also, your projection for Ocean waves is incorrect. I believe that figure comes from current Wave-Mechanic Generators. Future ones on the ocean floor, where the current is 80000 times stronger, will produce far more energy than ones as of today. Your number of 2.88x10^20 x 8x10^4 equals 2.30x10^25 J/year. Thats a lot more. Not to be mean or anything. That sounded mean, sorry.

As we understand it, the ingenious scientists at the Chinese institute of nuclear research (God knows what they call it) have developed a method of nuclear power generation utilising fuel pellets encapsulated within graphite spheres. This method renders meltdown impossible.

We are also aware of certain radiophilus bacteria which subsist on fissile materials such as plutonium and uranium. We surmise that they might be used to dispose of the waste products created through fission.

Hmm.... did anyone think of using the moons gravitational effects on our oceances....wait yes they did.....capturing...measurable force..converted into power, the tidal flows will allow us to forgoe our dependence on oil.. and yes there will be another step...as we progress towards an optimal efficencey..that is static and continual

power=force*distance/time

you cannot 'convert' force into power

and there is no such thing as a 'static and continual' resource.

entropy points the universe in a single direction. Energy cannot be created nor destroyed, nor can the order in the universe increase.

eventually, even energy generated by tidal waves will end.

of course, this is just a matter of wording- I am not arguing that we will run out of waves.

I simply believe one should recognize the difference between 'infinite' and 'renewable' sources of energy.

I think solar and wind is best.

Pro; solar is great if you have enough sun.

Wind is great if you’ve got a steady wind.

Con; the amount and placement of solar panels can be hard.

Can you put up a wind generator where you live.
