Energy cannot be created nor destroyed...........How?

because when oranges get old, the skin turns black and gets all moldy, hence energy, duhhh!!!!

Perpetual motion violates the law of conservation of energy (can neither be created or destroyed), so any "over unity" device will fail.  In fact, they won't even reach unity itself.  Any real world device will lose energy in the form of heat, even under the best conditions.

That's not renewable. You just demonstrated that perpetual motion is feasible! Hello Nobel! Can I get in on this?

In the laws of thermodynamics, it is stated that energy can not be created nor destroyed, but may be converted from one form of energy to another.  So, it might be better to ask how does one convert various forms of energy into thermal energy?\n\nWell, in the world of HVAC, we can burn a hydrocarbon fuel such as oil or gas (energy), and the products of the combustion process will be heat energy, light, water vapor, carbon dioxide, carbon monoxide (we try to create very little of this stuff), and vaporous and particulate matter (smoke .. again, we try to create very little of this stuff too).  The heat and light energy can be placed next to, or mixed within substances that have a lower temperature, and thus heat energy will flow from the hotter products of combustion to areas and substances that are cooler (heat energy always travels from areas of higher temperature to areas of lower temperature).  If a heat exchanger is used, the above products of combustion will be on one side of the heat exchanger, and substances such as cool air or relatively cool water will be on the other side, heat energy will flow from the hot products of combustion to and through the cooler heat exchanger material, and then will flow from the heat exchanger to the even cooler substance your trying to heat such as the water or air.\n\nElectrical energy can be converted to heat energy (thermal energy) by passing a current through a device that has resistance (a resistor).  It takes electrical pressure (voltage) to push the electrons through a resistive material, but any flow of electrons through the resistive material will cause the material to heat up.  The formula P = I x E applies here and “P” will be the rate of power measured in watts, “I” stands for flow of electrons measured in amps, and “E” is electrical pressure measured in volts.  To convert watt hours to BTU's (a watt hour can be a watt that is running for one full hour), you multiply watt hours times 3.413 (I have seen conversion factors ranging from 3.412 to 3.415, I’m not sure what the exact conversion is, but any number in this range will be pretty accurate).\n\nThere are other ways of converting other forms of energy to heat energy, including mechanical energy (friction), other chemical reactions, solar radiation, nuclear reactions  etc.

Hmmmm......... could it be energy?????

Energy cannot be created or destroyed- when the roller coaster is pausing before a fall, there is a tremendous amount of potential energy. When the rc falls, the PE gets turned into kinetic energy, so energy is never gained nor lost. the roller coaster will keep on moving until 1 or 2 of 2 things stops it: friction (brakes, air resistence, etc) or gravity, because an object in motion will remain at a steady velocity until acted upon by an outside force. that's all i can think of right now, and part of that isn't even involved in the 3 laws, sorry. ;)

The accepted fact of energy conservation. Energy cannot be born or destroyed just reshaped. Everything has mass, mass is made of matter, matter is made of energy. And since energy cannot be destroyed or created in the first place there has to be a source of energy how else could energy come to exist. That energy is the building blocks of the cosmos. now how could energy become energy out of nothing if there was no source to create it? \n\nAlso one is the chances of creation coming to existence in the beggining there is absolutely nothing. Then more or less the chances of creation coming into existence would be one one hundrenth over infinity (since nothing existed) yet how come the universe existed if there was no powerful intelligent force to back it up?\n\nAnd about life. could life suddenly materialize out of non-life? as some evolutionists (Evolution dying science)propose so? If so how could non-life turn into life if there was no intelligent desing behind it?\n\n\nThe Theory of evolution is a lie. Creationism defeats evolution. Let me explain: Science has proven that DNA is the building blocks of life, and all scientists agree that DNA is material that stores information on the creation of an entity. micro-Evolution has been proven, but macro as in: "Massive modifications on a large scale?". Evolutionists argue that since everything evovled from bacteria you have to consider this fact. DNA is programmed to produce the same amount and quality of DNA they are born with. Then Why does the genetic code of the bacteria has significantly less genetic input as compared to that of the human's this proves the falcity of genetic evolution from bacteria to current day human. In all experiments with evolution. it is obeserved that creatures mutate only by shuffling or rearanging their genetic structure. think of it as Hyper Active Malnurished Albino chiwawa has a genetic structure of A-G-H-I then the mutation occurs and her oofsrping is a Hyper Active Malnurished Dehydrated Chiwawa, it has a genetic structure of A-G-H-I they are both the same creatures but only the latter "evolved" but never was it observed the a mutation had produced extra genetic code. so if a bacteria has only 10000 units in its genetic materia how come somthing as simple as a plant has x 10 more genetic materia if no intelligent being had put the extra materia there in the first place. since DNA is so complex even one modification to a molecule can tottally change the product ie: instead of a butterfly it's now a moth how could we have so much diverse and stalble life forms if everything evovled from an ameoba?  Religion was right, GOD does exist, science is only publicizing this now.

It is theoretically possible to make anything a gas (including that).  It would take way too much energy to do so though.

The energy does not become matter.  The partcles are the matter.  You, and everything around you, are mostly empty space.

you can't convert heat energy directly into free energy (electric current).  That would violate the second law of thermodynamics.  you can use a temperature DIFFERENCE to harvest free energy from thermal energy...

they can't.  That would be a perpetual motion machine.  \nConservation of energy says that you can't get something for nothing.  for a terrestrial body to do work continuously it would need to be given a continuous supply of energy.\n\nIn an elliptical orbit, two boddies can take turns doing work on each other and energy is conserved.

1. Energy cannot be created or destroyed only changed in form. 2. The total energy of any closed system is = 0\n\nA static generator does not create energy it only changes its form from mechanical to electrical.  Search on the web for perpetual motion for a more in depth explanation.\nalso search thermodynamics, first and second laws.

By the law of conservation of energy, you cannot create or destroy energy, only change it from one form into another.\n\nDark or not, energy is energy. You cannot create it.\n\nAt the moment, dark energy and dark matter are theories which scientists have come up with to explain the "missing matter" in the universe.\n\nThere has been a dark matter galaxy "found" which supports this theory.

The top answer is incorrect.  In both cases, the current woul go on infiniitely, because energy will keep on traveling, but the current will get weaker and weaker, because it will keep spreading aparty, until the ammount of current in negligeble.\n\nHope this helps.

static energy at birth and cosmic energy at death(energy can neither be created or destroy,but can change from one form to another)

Maybe this can help...all you have to do is a search in Yahoo or Google...\n\nhttp://www.think-energy.com/ThinkEnergy/11-14/activities/EnergyTrans.aspx\n\nTry searching for "energy" or "kinetic energy"

You can't make a perpetual-motion machine, if that's what you're getting at. Whatever loop you make, you'll always end up losing energy until it stops, unless you are putting energy in (solar) but then what's the point?
