Great article, really informative.
And yet, power just means energy flow per unit time. We all know the Watt is a unit of power consumption and have an idea how quickly a 1500 Watt kettle boils water. The unit of energy is the Joule - a Watt is just a flow of one Joule per second. The other popular unit of power is the horsepower. The conversion is that one horsepower = 756 Watts. A 100-HP car would be able to turn a 75,600 - Watt electrical generator, or 75.6 kilowatts. So anybody who does talk about energy, rarely speaks in Joules.
Electrical power is the rate at which electrical energy is converted to another form, such as motion, heat, or an electromagnetic field. The common symbol for power is the uppercase letter P. The standard unit is the watt,symbolized by W. In utility circuits, the kilowatt (kW) is often specified instead;1 kW = 1000 W. One watt is the power resulting from an energy dissipation, conversion, or storage process equivalent to one joule per second. When expressed in watts, power is sometimes called wattage. The wattage in a direct current (DC) circuit is equal to the product of the voltage in volts and the current in amperes.
