do you kno anything that breaks down somthing to make energy?

If you're human, you do.  The food you eat is broken down to make the energy you need to live.  The energy is measured in calories.

Just so it doesn't use too much energy!

The answer is (D) simple sugars.  However, cells must break down glucose through cellular respiration (glycolysis or fermentation) to create ATP, which is the energy molecule used for cell processes.

I think what you are really asking is what different forms of energy convert to other forms of energy.  Mechanical energy can be converted to heat through friction.  Electrical energy can be converted to sound energy with the use of varying electrical currents and permanent magnets.  The splitting of atoms releases huge amounts of electromagnetic radiation of a huge variety, from electrons, to photons, heat, light, etc.  Light energy (photons) can interact with semiconductors in solar cells to produce electrical energy, also known as electromotive force.  I am sure someone has a comprehensive list of the primary energies that we know about.  \n\nIt may help, however, to discuss energy in terms of storing it.  Gas under high pressure in a closed cylinder has high potential energy.  The release of this pressure can cause thrust (like a rocket), or cause a super-sonic shock wave that can blow things up.  Certain chemicals have energy stored in them which is released through chemical reactions.  A rotating wheel has energy stored in the mass about the rotating axis, known as rotational momentum.  The magnetic field in an inductor, like a vehicle ignition coil stores energy in the field in the core, and releases it when the current to the coil is interrupted.  \n\nIn simpler terms, mechanical energy can be turned into heat, light, electromotive force, or pressure. Chemical energy can make heat, light, electromotive force, or pressure (not a complete list).  Atomic reactions (fission or fusion) release huge amounts of energy all across the electromagnetic spectrum.  Hope this is food for thought...\n\nSee a study of thermodynamics and entropy.  It would appear that all energy flow is headed in only one direction, always at a net loss.  See the link.

Many forms of energy exist around us. Energy cannot be created or destroyed, only changed from one form to another. If a person ever says that energy is lost, what really happens is that energy is spent or changed into different forms. It never really is lost. For example, if you use water energy to create mechanical energy, you might "lose" some energy by creating heat energy in the form of friction.

Hydrogen powered autos is the way to go. The sun's energy can be used to separate Hydrogen from Oxygen, so you definitely have something environmentally friendly.

I assume you mean electrolysis?  I don't know the exact ratio of energy out to energy in, but I do know that it's not very efficient.  There will be a lot of lost energy.  What kind of H2 on demand system?  Are you trying to run an automobile?  If so, you'd need more than about 10 kilowatts of electricity.  Might as well just build an electric car if you have that much electricity to waste.

The source of energy is food. Food is digested, giving you energy.

It would end up as heat. At least that is the usual place you say all the energy went when you can't otherwise account for it. Like where does the energy go when you drop a bean bag on the ground? Yell out loud? Turn on a light? slow your fall with a parachute? And on and on and on.

Just how much Hydrogen do you want to produce?\nI could tell you several ways to make small amounts for next to no cost, but if you want to step up production, it will involve increase the price too.\n\nElectrolysis of water is probably the cheapest method, especially when the energy your using is cheap/free too.  The cheaper the energy, the cheaper the over all price.  The energy from a battery is much more expensive than the energy "out of the wall" which is much more expensive than energy from the sun (free).\n\nYou could also produce Hydrogen by reacting a more active metal in an acid.  Metals like Iron, Zinc, Magnesium, (you could use the Alkili metals, but I woulnt advise it), ...\nCopper (in a penny) wouldnt work since it is less active than Hydrogen, but the zinc inside the penny would. [we ignore the cost of the penny you have to destroy]

Solar energy is the best energy in my view .With the help of this solar energy we can use solar cookers,solar lamps,solar geasers\nsolar heaters, solar refregirators etc

It is not possible for usng slar energy directly. because the compresser operations want frequent input. ( Not continuose). In the form Solar electricity is possible. \n\nHow ever Vapour Absorption syastem is possible

no. there is no such case , theroretically. because, according to the law of conservation of energy the total energy in any closed system is constant. however practically some energy is dissipated in a practical case.
