Because there are no significant amounts of electricity in nature - at least, not in a form that can be used. (No way has yet been found to harness the energy from lightning.)
Depends what the source of electricity is.
Electricity
solar
No.
A computers energy source is electricity. When using a computer plugged in or not it is drawing electricity from the battery or from a plug which is connected into the PC and a wall outlet. When there is no electricity the computer cannot function.
Solar panels convert sunlight into electricity through a process called the photovoltaic effect. The energy source for solar panels is the sun, which provides a renewable and abundant source of energy.
Some use electricity, most use gasoline.
a current of water to move the energy producing aparatus.
Electricity is the naturally occurring source of energy that we are yet not able to harness and use.
For electricity it is still coal, for transport it is oil
A fridge typically uses electricity as its source of energy. This electricity powers the compressor, condenser, and evaporator to maintain a cool temperature inside the fridge and keep food items fresh.
Electricity is not a "source" of energy at all, since there aren't large amounts of electricity in nature which we can just use. Well, there are lightnings, and the electric charge of the atmosphere, but no practical way has been yet to use it. If you were to find one, it would be a renewable source, because you could take a certain amount of this energy for a long, long time.Electricity is not a "source" of energy at all, since there aren't large amounts of electricity in nature which we can just use.
