What percentage of generated electricity is used for residential use?

This is not the answer to this question. It depends on your power factor! Power factor is the measurement of the percentage of "clean" electricity you get from your electric company. Low power factors can be corrected by installing a unit like "powermax3000". Most U.S. pf's are in the .75 to .92 range. In the case of a .75 pf, only 75% of your electric is being used effectively.

How electrical energy is generated, transmitted and distributed?

Electricity is distributed via electric distribution substation. At the substation, the high voltage electricity from the high-voltage transmission lines is passed through step-down transformers that lower the voltage. The electricity is then transmitted to network of local electric distribution lines. Before electricity enters a home, the voltage is again lowered using step-down transformers. In most countries the voltage is 220 V AC or 110 V DC. In a home, electricity is distributed to ...
