I am planning to buy a 500 watts power supply, but at the same time i want to conserve energy.
Does a 500 watts power supplies uses 500 watts every time i run a computer?
It means that it can distribute a max of 500 watts of DC power to the computer at 1 time. The amount of AC power it's drawing depends on what you're doing at the time, and what your hardware is.

No, its capable of providing up to 500 watts. If you are energy conscious, then investigate the power supply you are buying and make sure you get one that runs at least 80% efficient. Some of the cheaper PSU's are only around 60%.

Nope!
Main thing to remember,
A COMPUTER ONLY USES THE POWER IT NEEDS
If you have a 10,000 watt power supply, and your computer only needs 100 watts, it only uses 100 watts!
Edit:
Thought I'd comeback and add.
I recommend this power supply,
