What Does energy end up as?
537611
Do you know Einstein's theory e=mc(^2)? In theory (taking out the relevant c for these purposes), it means energy and mass are the same thing ("e" is energy, "m" is mass; a packet of light is considered a particle, etc). Mass and energy are never created or destroyed, simply "change" from one to the other. For example, you get up in the morning and you eat a carrot. I don't know why you'd do that, but say you do; where does that carrot go? G-rated/simply speaking, that mass is translated into energy for your body to use. Your body gives off energy through things like motion and heat when you move, but the mass/concept of the nutrients you received from that carrot weren't lost, were merely translated into an equivalent amount of energy, which your body then gives off. If you go from mass --> energy --> mass, hypothetically, repeatedly, hundreds and hundreds of times, you will end up with the same amount of mass/energy each time.

It is the transformation of potential energy, converted into kinetic energy, which in turn is converted to hydroelectric energy by the means which you described....KECK

As electricity flows into certain atoms (which make up LEDs), energy is transferred to the electrons in the atoms.  Those electrons absorb energy and rise to a higher excited state.  At some later point in time, those electrons fall to a lower energy state.  The difference in energy between the higher state and the lower state is emitted as a photon.  The amount of energy in the photon determines the color.

When heated the electrons move from the ground state to an exicited state.  They are unstable here and return to the ground state giving off energy in the form of a specific color.  Different energy levels will produce different colors

If you consider that matter and energy are two forms of the same thing (that's what the E=mc2 is about), then yes, this is never created or destroyed.  Some matter is converted to energy (e.g. nuclear burning in the core of stars), but it is never completely destroyed.  So yes, everything created is still here in some form or another.

Your question leads us to try and come up with what creates energy and that is not going to happen.\nI suppose you are asking what conversion processes exist and which is best for your needs or the needs of the general population.\nThe energy in fossil fuels is converted to heat and the most popular source is coal because it is least expensive.  That heat energy from coal is then converted to electricity at most power plants.\nThe energy in petroleum is converted to kinetic energy in your car's engine.  Since we buy millions of barrels per day, one can assume it is the most popular.\nThe energy coming from atomic fusion is the greatest energy used on the planet.  We get it from the sun.  We can capture that energy and convert it to electricity too.  Not only is it our planet's greatest source of heat, but also is the greatest source of light.  Given the number of people sunbathing at the pool, one can assume it is the most popular, too.  Atomic energy can also be pulled from uranium and turned into electricity or used to destroy entire towns.  One is popular, the other is not.\nPlease add some more info to your question.  It is too vague for me to answer well.  Just as minootoo points out, the pros and cons of ALL sources of energy is beyond the scope of this forum.

radiant energy is of a short wave length. After it is trapped inside the atmoshere it begins to bounce ( reflect ) betweent the layers..the result is the short wave lengths become longer and slower, releasing the stored energy...just like when sunlight beams into a car...80degrees outside but 120 degrees inside!

states that energy never vanishes it just chamges into another form of energy

You should re-ask.  Do you mean strength or heat or both?  We also produce electricity and build chemicals that store energy.  You need to define output better.

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.

Electricity doesn't exactly do work.  Electricity is a form of energy that enables other things to do work.  Like food in your body.  Your body does the work, the food provides the energy.  Electricity is one form of stored energy that is extracted from a number of different sources, like coal, oil, the sun, flowing water, or splitting atoms.

Energy is created.\nPhysicists currently believe that about 75% of the energy in the universe exists in a form known as dark energy.\nThis energy has a constant density over all space regardless of what the space contains and so the total amount of dark energy increases as at the same rate as the increase of the volume of the universe (which is expanding).

Nothing is nothing. Energy is something.\n\nIf there is nothing in a universe then is it even a universe?  No, it is not, it's nothing.

well energy is used only in the beginning to start the reaction. otherwise an exothermic reaction will give out tremendous amount of heat energy.

It would be heat and sunlight- A cycle means that a substance or energy will eventually return to its origin.  Sunlight generates heat and chemical energy on the Earth, but is non-cyclic, in other words, you have to have a constant infusion of it all the time, it doesnt recycle.  The majority of the energy of sunlight is lost as heat, out of our atmosphere into space, never to enter the cycle again. So the flow would be sunlight in, some chemical use and some heat absorption, and eventually all the energy is lost as heat out.

ONE THING IT MUST HAVE POTENTIAL ENERGY BUT FOR YOUR CONVENIENCE I ASSUME IT HAS 0 KE & PE\nTHE TOTAL ENERGY OF A SYSTEM REMAINS CONSTANT SO IT MUST HAVE "ZERO" END ENERGY

You are quite right that what is meant by the term energy is at best often ambiguous, and saying energy can convert from one form to another is unhelpful because it introduces "flavours" of energy. This confusion has historic origins - at one time, different forms of energy were thought to be different and it was not obvious that they were interchangeable of equivalent.\n\nThe easiest way to think of it is this.\n\nThere are two ways in which a particle can be said to have energy.\n\n1. it is moving (including vibrating)\nthis accounts for many of the things you think of as energy - heat is vibrating molecules, electricity is moving charge etc, and of course a speeding bullet has "kinetic energy"\n\n2. it is in a potential\nthis means it is being pulled by one of the forces of nature (gravity, electrostatic or strong nuclear) - if it "gives in" to this force it will accelerate (ie move) and have energy of type 1, and hence this is often called potential energy\nthis accounts for things like the energy in chemical bonds, nuclear energy, the energy in springs etc\n\nNow you can see that you can convert energy associated with moving to energy in a potential. For instance, if i fire a bullet in the air, first the chemicals in the explosive react. This means the electrons rearrange to have a little less energy in the potential created by the nuclei, and this energy is release. The released energy is converted to the energy of motion of the bullet. The bullet flies into the air against the force of gravity and it gain gravitational potential energy as it rises; it also slows down so it is losing kinetic energy.\n\nOne of the triumphs of science was to show that all of these energies are the same - i.e. that none is gained or lost.
