The most practical use of electrical measurements most often used would be a kilowatt-hour meter which is attached to usually a home electrical system to measure the amount of energy used.
What is practical is a relative question. The unit for electric cars and biology may be Kilo Joules and ev, electron volts.
In 1888; but a little before James Blyth was built the first eolian generator. Also wind energy was not invented, it is a natural; only the practical applications can be called inventions.
In electric bell, electrical energy is converted int sound energy.
Electric energy to kitenic energy
An electric motor does that.

Electric wires are used as conductors, to conduct an electrical current. The practical use of this is either to transport energy from one part to another, or to transport signals.
As energy can neither be created nor be destroyed. It can be transformed from one form to another. Hence ,in various applications energy is only transformed. For eg. : Electric motor
Electric bill calculators have many applications for the home. First you enter the current light bulbs and appliances that you operate. The you very the wattage and numbers and see what ones cost the most, and where you can cut to find savings on your energy bill.
Electric Energy is the energy of the Universe. All energy is electric energy. Gravitational Energy is electric in the sense that matter is held together by electric energy. Briefly, Electric energy is E= - q1q2 zc/r where q is the electric charge, z is the free space resistance and c is the speed of light.
it is practical, but energy consuming

Electric motors take electric energy and turn it into kinetic energy Generators take mechanical energy and turn it into electric energy
