By 'speed of electricity', presumably, you mean 'speed of current'? We don't normally measure the speed of current but, rather, its intensity. The unit of measurement of current is the ampere (A), which is one of the SI system's seven base units. The ampere is defined in terms of the force a current produces, due to the magnetic field surrounding it, between two, parallel conductors.

In the SI, any type of energy is measured in joules.
All forms of energy are measured using the same units. The SI unit for energy is the joule (J). However, the unit used by electrical utility companies is the kilowatt hour (kW.h).
Ohm
Electric energy used in homes is measured using a kilowatt hour meter. This is the meter that is found on the outside of your home just below where the utility company makes a connection to your house.
