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.
Turning off your computer when not in use saves more energy compared to leaving it on. The amount of energy used to start up a computer is minimal compared to the continuous energy consumed when the computer is left running. It is typically recommended to turn off your computer when it will not be in use for an extended period to save energy.

cholesterol do not provide energy to body because the energy that contains the it wastes ots of energy so it doesnt provide energy.
It depends on the type of light. A fluorescent light takes a lot of energy to start up, and almost nothing to stay on. So leave the Fluoro on. A normal light bulb doesn' matter how many times you turn it on and off, it is cheaper to turn on and off. If you're leaving the room for more than a few seconds, you're wasting power leaving any lights on, other than possibly large fluorescents with ballast starters. However, all lighting burns out faster if you cycle them on and off more. Would you rather waste energy with more light than you need, or waste energy having to replace bulbs more often?
Yes, leaving a light bulb will damage the environment because the energy used to light the bulb comes from a coal fired station and whilst the light is on, coal is burnt which releases carbon dioxide into the air which may contribute in global warming.
For starters, anything that wastes energy - like leaving lights on when you don't need them.

Obtaining nuclear radioactive wastes
It has poor regulation and wastes energy.
