There is a lot of standby energy consumption that people do not realize they use. In Australia this works out to be about 80 watts per household. This can be minimized by turning off devices at the wall. Real time building energy meters can show how much you are using in real time, cost per hour, daily totals, monthly totals. Once such a device is in place the household energy consumption usually falls 20%.
2/3 of energy input is wasted at the power station.
In most energy transformations, part of the energy is wasted. Much of the wasted energy is usually converted to heat.

Blood? Wasted? Wow! My whole perspective has changed!
Usually, much of the wasted energy takes the form of heat energy. However, part of the energy can also be in other forms, for example sound.
Well it all depends on how youy look at it

The power is specific to the lamp set.
They are used to show how much energy is used and how much is wasted in an object/item.
Because they dont use their energy that much
A lot of energy can be wasted at schools. Sometimes, central heating is left on in rooms with no one in them.
Useful energy is energy that can be converted to any other type of energy. Wasted energy is no longer available to be converted - usually because it got spread out too much, or because it got converted to heat. Heat can be partially, but not completely, converted to other types of energy.
