On average, an AC unit uses about 3,000 to 5,000 watts of energy per hour.
The unit used to measure the average kinetic energy of a substance is joules (J).
60!
The same units as for any type of energy. There is no special unit for kinetic energy.
On average, a computer uses about 60 to 300 watts of energy per hour, depending on its size and usage.
depends on the size of the unit you want to use and the size of the window plus how many rooms you are trying to keep cool and if the unit is energy efficient and depends on how much you are willing to spend on the unit
How much electrical energy does the average person use in a day . . . In the UK the figure is about 16 kilowatt hours.
17cm
kilowatt-hour (kWh)
LEED for Homes 2009, states that an average sized home will use electric load of 10,000KWh annually
Traditionally, this was measured in calories, or Calories (equal to 1000 calories - note the uppercase!). But the tendency is to use the official unit of energy - the Joule. This is the same unit that is used to measure any type of energy.
The basic unit of energy that scientists use is the joule (J). It is equivalent to the energy transferred when a one-newton force acts over one meter distance.
The number that tells you how much electrical energy a machine will use in one year of average use is called the annual energy consumption in kilowatt-hours (kWh). It is a measure of the total energy the machine consumes over the course of a year if used normally.
