Electricity is scale-able, from picowatts to Gigawatts; it is transmittable; it is storable; it is convertible; and it is affordable.
Mechanical energy
Electricity is not exactly the source; it is the way energy is transported. The reason electricity is used is because it is an easy way to transport energy from one place to another.
solar energy

another source of energy must be used to make electricity
Electricity
Any energy source that generates electricity can be used to run an electricity pump for water. Without electricity, wind power, like a windmill, can be used to pump water, as it has done since the time of the Romans.
Coal is the most used source for electricity in the US. World wide, other countries, I don't know.
Biomass
Electricity and after that natural gas.
noelectricity is a source of energy
The most common source of energy used to produce electricity is fossil fuels, such as coal, natural gas, and oil. These fuels are burned to generate heat, which is then used to produce steam that drives turbines to generate electricity.
