The electrons created during chemical reactions in a battery can travel through a conductor (such as wire), which then gets transformed into electricity that can be used to power our gadgets both at home and in our offices. The chemical reaction gets completed as soon as the electrons travel back to the other arm of the battery.
If we are talking of the electrons then it means we are talking about electric energy. Actually the energy is created by the energy generators like wind turbines, hydro power plant etc in which a turbine is rotated by a force of water or wind or any other force. Also it can be generated by using solar panels having photo diodes which converts light energy into electrical energy.
This generated energy is stored in the batteries whose charge is processed for further use
The flow of electrons is due to the difference of potential between two points causing the energy to flow from the higher potential to the lower potential.
It is only the electrons which are responsible for the creation of the energy.
I know murder and stuff is really serious but you can't lie humans are over populating and polluting the earth murderers and etc lower that I'm not saying it's good or bad but we really need to consider this earth might not be here the next morning anything could happen.
