Energy
Yes
batterys
electric train run by obsorving electrical energy from the trans mission lines and storing that energy in the batterys and transmitting that energy to the wheels
it needs to eat eat copper and metal or maybe batterys at times to get energy

some batterys
green energy source
The term clean source of energy refers to only primary energy sources as wind or solar energy. Electricity, by definition, is not a primary energy source. It is a secondary energy source that is could be produced by a clean energy source as wind or any renewable primary energy source or produced by fossil energy source as oil, natural gas, or coal.
waves is not a source of energy
No its not a source of energy..... geez...
The efficiency of batteries is typically around 80-90%. This means that when charging a battery, 80-90% of the input energy is stored as chemical energy, and when discharging a battery, 80-90% of the stored energy is converted back to usable electrical energy.
