putting a switch on the plugs in my house?

[t-maxxracer32]

hey guys i was bored yesterday thinking about this and was wondering how it would work.

as everyone knows electricity is a freakin crazy high bill, and i was thinking of ways of helping my parents out.

i figured that at night when everything is plugged into the socket it is pulling some amps and using unneeded power. if i could mod a switch onto it and make it to where they can turn off the power then would that make it to where there is alot less energy being used? or will it be so little that there will be no difference on the bill?

i honestly have no idea how to do this but if i find out it is worthwhile then ill turn off the power to my room and test it out to see if i can get it to work.

i think it would be cool if a simple thing like this could take 50 dollars off the phone bill.
