nuclear energy is a hidden ,concentrated,compressed energy.You just leave it free and use it.it is everywhere and in everything.just get the technology to get it out .it is the ultimate source of energy,clean ,easy to use and will be in absolute abundance.

renewable - Wind power - cheap, available, enviromentally friendly & does not run out. Disadvantage - has to be windy/exposed, initial cost of setting up, can be considered unsightly\nTidal - Cheap, enviromentally friendly, available around the world & does not run out. Disadvantage - cost of setting up, small return for initial investment, suitable locations\nSolar - available, enviromentally friendly, relatively cheap after installation. Disadvantages - Cost of setting up, sunny location needed, storing power\nNon Renewable - Nuclear - reliable, clean, economic. Disadvantage - enviromental hazard, safety, disposal of waste\nFossil fuel Coal & gas - widely available, relatively cheap, established technology. Disadvantage - limited source, carbon emmissions, price can fluctuate

http://en.wikipedia.org/wiki/Nuclear_fission\n\nEffectively generating energy from breaking down an element to at least two smaller elements.\n\nThis is the reaction that takes place in bombs and power plants. This is distinct from fusion

This is a debate we're going to have to have here in the US soon...are the risks of nuclear power worth the benefits.  I think there's nothing wrong with nuke power, having worked around it for several years in the early 90's.  I think irrational fear is nuclear power's biggest obstacle.  People fear what they cannot understand.  They see Chernobyl and think that's going to happen all over again in their backyard, when the fact of the matter is that modern nuke plants are as safe as any other industrial facility handling volatile materials.  The UK would be well served by building new nukes and opening up research on alternative power sources simultaneously.

Every atomic fission releases excess energy in a variety of forms.  That excess energy is trapped by the reactor in the form of heat, which is used to generate steam to drive turbines which generate electricity.

The best energy source depends on what you want and which factors you consider important.\n\nMost people would want something that is clean, safe and reliable as well as cost effective (with predictable pricing as well).\n\nNuclear Fission meets those requirements better than anything else in most cases.  When used with centrifugal enrichement it produces less CO2 than anything else, has a much better safety record than most of the competition (way better than hydro, fossil fuels and wind) and can provides power when it is needed instead of when the wind is blowing or the sun is up and is cheap enough to compete with pretty much everything even with all the environmental costs included in the price.\n\nIt also has the advantage of being doable with todays technology and infrastructure.  Should someone figure out how to store the energy from solar and wind on a large scale or we develop the capablity of putting solar power plants in orbit (which I think we should do) or get fusion to work (yeah right) then it would probably change.

Hi, Kenny. You are asking for a lot of information. I have written a book, on the history of nuclear science and will link you to it to read online. This space here is awfully limited.\n\nThe short answer is that nuclear science allows us to generate electrical power out in space even when we are far away from stars like the sun. \n\nThere are two ways we do that:\n\n1. Nuclear reactors - just like the atomic power plants on earth, reactors depend upon the splitting of uranium or plutonium atoms to generate heat and then the heat is used to boil a liquid and turn a turbine. The turbine moves a coil of wire through a magnetic field and gives you electricity.\n\n2. Thermopyles - plutonium due to its alpha radioactive decay gets pretty hot naturally. If you put two dissimilar wires wrapped around each other in a heat source and then the other end of the wires in somewhere cold (like out in space), electrons will flow through them. This is called a thermocouple. If you put lots of those together, you have what is called a thermopyle. This kind of technology is pretty flawless and is used even for things like heart pacemakers.

Do you mean electrical power from a Nuclear power plant?\n\nIn a nuclear power plant, a reactor contains a supply of enriched uranium.  This radioactive material reacts with itself as it decays, producing heat.  This heat is used to heat water into steam, which turns a steam turbine, which turns a generator (much like in a coal burning plant).  Due to concerns over leaks of radioactive material, there is usually two steam/water loops, one that goes through the reactor and then through a heat exchanger to heat the water in the second loop that goes through the turbine.\n\nNewer reactor technology replaces the first water loop with helium gas instead, resulting in an even safer reactor design.

A nuclear plant is efficient and very clean. They probably dont cost that much more than any other sort of plant. The disadvantages are straight forward, if anything goes wrong then they go very wrong.

I think that nuclear energy source is a viable energy source as long as we do everything we can to make it as safe as possible.  If we do nothing to find new energy sources our economy and our way of life can deteriorate.

To answer the first question, most power generation currently in use comes from burning things (coal, oil, gas, wood), that contain carbon in their molecular structure.  This carbon is combined with oxygen (typically from air), creating carbon dioxide, and releasing energy.  This carbon dioxide is released into the air.  Depending on the fuel source, other components and contaminants of the fuel may be burned or released as well, producing other types of pollution (such as mercury or acid rain).\n\nWith nuclear power (fission), the energy comes from a reaction contained entirely within a nuclear pile (generally made of uranium or plutonium).  Neither carbon nor oxygen needed for the process, and so CO2 is not produced.  In addition (at present), generally all of the waste products of the reaction are kept sealed and contained at special storage facilities.  While these waste products have the potential to be hazardous, because they are kept sealed, the environmental impact is greatly reduced.

Advantages\n- Solar energy is renewable (i.e. it will not deplete)\n- Solar energy is  clean (it does not give out pollutants)\n- Solar energy is readily available (there is sunshine quite often)\n\nDisadvantages\n- Solar energy is difficult to harness (technology is kind of advanced now, but still, the energy absorbed is quite little)\n- Solar energy cannot be stored (if we rely totally on solar energy and we can't store it, what are we to do on a dark day or at night?)

Nuclear power is a 'clean' power in that, under normal circumstances, the only emisson is steam from the reactor. However, if there is a meltdown, like the one in Russia a while ago, the effect could be very threatning.

Nuclear fusion is the process of creating usable energy by fusing, or combining, the nuclei of two light atoms (like deuterium) into the nucleus one heavier atom (like helium). This is the process that powers the Sun.\n\nSo-called "cold" fusion was a claim (since widely doubted) that this fusion of nuclei could be done chemically, without the high temperatures and pressures that most physicists believe is necessary for fusion to occur.\n\nFusion is a nuclear process, but it is quite different from conventional nuclear power, which is a process called "fission." In fission, a heavy nucleus, like Uranium or Plutonium, is split into two lighter "daughter" nuclei, releasing energy.
