Leaving any electrical device on consumes power. You get charged for what you use. With no power consumed, no charge.
A+ Nuclear energy
The energy transfer is: chemical --> light and heat the heat is the waste product
cholesterol do not provide energy to body because the energy that contains the it wastes ots of energy so it doesnt provide energy.
If it is 100 watts, on for 12 hours, this is 1.2 KWh. This would probably boil a kettle every 10 minutes if you wanted to, or run a one bar fire for just over 1 hour.
Not likely - any machine wastes some energy; that would reduce the useful output energy.
For starters, anything that wastes energy - like leaving lights on when you don't need them.
When it wastes energy you would rather keep - which is quite often.When it wastes energy you would rather keep - which is quite often.When it wastes energy you would rather keep - which is quite often.When it wastes energy you would rather keep - which is quite often.
Definition - Wastes in your body. Causes of poop - Nutrients from food and turning it into energy. With the left over of the non-nutrients will be poop or peed out.
Let's consider these situations : 1) You turn it on at six o'clock am and leave it turned on till six 0'clock pm . 2) You turn it on at six o'clock am and it keeps it on during 2 hours. Then you turn it off during 2 hours. And so sucessively until six o'clock pm. Obviously the computer wastes more energy on the first case. But all depend on the variations of the time you keep it continuosly on, and the variations on the range you keep it off and on. In other words, it may spend more energy by turning it on and off several times, and may spend less energy by keeping it on continuosly. It's a matter of a simple math operation.
