How is electricity generated and used.?

Short answer:  Electricity and magnetism are two sides of the same coin; each can cause the other.  For instance, moving a wire through a magnetic field can create a current, while current flowing through a wire also creates a magnetic field.  Thus, one can generate electricty by using some kinetic energy source--water, wind, what have you--move powerful magnets through wire coils.  There are other ways, of course.

electricity is either made by chemical reactions, or by moving a magnetnic field over a copper wire, as i am sure you allready know, so the problem is geting a force that can move the magnet, to give inductance in the wire. causing a current to flow.\nwater turns the blades of a fan, or tubine whitch is conected to a magnet witch turns inside a copper coil.\nso any natural way that can generate enough force to move the magnet, can be used.\nwith nuclear the heat is made in a chamber called a reactor whitch turns the water to steam the steam turns the turbine whitch is conected to the magnet.\nif you have a propella connected to a magnet that is moved by wind that is driven by the sun, inside a copper coil you get some electricity\nin water fall the downward force of the water turns the blades, withch turn the magnet, inside a coil,\nall diffrent ways of doing the same thing.\nnot sure about forrest though, unless you burn the wood to make steam, to guess what turn the magnet inside the copper coil. or maybe you could cover the tree in magnets, and buld a copper coil next to it, then wait for the wind to sway the tree

a hyrdo electric generator works by using water current flowing againsnt a wheel that in fact turns the generator wheel creating electricity, just like when you put your hand against a current it opushes against your hand, except its being diredcted twards a wheel that catches that current turning it into energy

There is a lot of possibilities starting from the simplest one which is wind generator.  More complicated would be water generation where a usually dam is build and potential energy of the water accumulated behind the dam moves water through turbines and generates power. Some other may include thermal energy of the earth. If you drill deep enough you will get to the earth crust zone where temperature is high to produce steam and this steam is converted (generated) into the electric power. Ocean waves are also source to generate energy.

Moving water -- generally provided by a river -- is used to turn a turbine.  The turbine is wrapped in conductive cable, and the housing is lined with magnets.  Thanks to the Oersted Effect (or maybe the Faraday Effect; I get them mixed up), moving a conductor through a magnetic field generates an electric current.  The stronger the magnets and the more conductor involved, the more current you get -- which is why hydroelectric turbines are so freakin' big.

when you provide the current, the generator induces a current, i.e. the production of current due to the availablity of a initial current.

How was the electricity produced?  If it was from coal, then it is a dirtier form of energy than Natural gas.\n\nIt is more efficient to heat with natural gas than electricity.\n\nNormally, it is more efficient to cool with electricity than with natural gas.\n\nNatural gas is a non-renewable resource (at present).  Electricity can be produced by hydro-electric, coal, solar, wind, etc.\n\nHouses don't explode when they have an electricity leak, they can explode from a gas leak.

Hi,\n\nYou know that if electricity is apllied to a coil over a magnet it causes mechanical movement due to the formation of magnetic fields similarly the converse is also true\nthat if mechanical energy is applied to a similar but reverse arrangement electricity can be produced\n\n\nwhen current flows magnetic fields are induced but if a fluctuating magnetic field forms in a ciol electricity is induced

It would actually be pretty easy to use a bike to generate electricity.  You would need a bike, wire, magnets, and some resistors to get the right current and voltage.  If you could find a way store to store the energy in some type of battery, that would be ideal.  Otherwise, you could use it to power small appliances.  Most people don't do it because they don't know it's possible, don't care, don't know how, or don't think about it.  If you are interested in that, you should design something.  It would take a lot of bike riding, but it would be possible (especially if you had a good transformer to step up the current, which would be easy to build as well).

There are many ways to take advantage of the energy produced by the sun.  A good place to start is with a passive solar energy water heater.  They are inexpensive to install and easy to maintain.  The simplest ones use the radiant energy of the sun and convert that to thermal energy using a material that absorbs the light instead of reflecting it, in layman's terms, something black.  \n\nPhotovoltaic (solar cell) systems convert sunlight directly into electricity. A solar or Photovoltaic cell consists of semiconducting material that absorbs the sunlight. The solar energy knocks electrons loose from their atoms in a semiconductor, allowing the electrons to flow through the material to produce electricity.\n\nFor a more in-depth explanation of photovoltaic technology try this site.

electric can come from solar energy gas is made of oil and if people use gas powered cars earth might run out of oil and solar power can keep on going
