How can I report to how much $ my plugged within electronics are costing me?
Anyway to tell how much wattage is used when my electronics are be idle whether it be in standby, sleep, or past its sell-by date? I read this article on Yahoo! on the topic:

Is there some inexpensive device that can recount you how many watts are drawn by objects plugged contained by to them? Or an easier/alternate method?
Answers: For about $30-40, you can procure a device called a Kill-A-Watt electric usage monitor that displays much information give or take a few an appliance's electric usage. See the review below.
Another way is to separate the insulated wires of an extension cord and clamp a clamp-type AC ammeter around any the hot or neutral (i.e., not the ground/earth) line. The AC ammeter will measure the current (i.e., amps) that an appliance draws. Multiply the current by the voltage to procure an approximation of the power used. Then, multiply that by the duration the appliance will be used to get the gusto used. Multiply that by the cost of energy to find out how much your plugged-in electronics cost to operate. For example, 1 amp times 120 volts equals 120 volt-amps, which, depending on the appliance's power factor, is approximately equal to 120 watts. 120 watts times 24 hours equals 2880 watt-hours, which can be expressed as 2.88 kilowatt-hours. If you're paying $0.15 per kilowatt-hour, the 1-amp nouns will cost about $0.43 per daytime to operate, if operated continuously.
If an appliance list its power consumption or current draw on a label, you can use that as a idea for your calculations in need having to give somebody a lift any measurements. For example, a laptop power supply that draws 65 watts (i.e., 65W) is drawing about a 1/15th of a kilowatt (65 * 15 = 975, which is almost 1000), so, if you reimburse $0.15 per kilowatt-hour, the laptop would cost about one cent per hour to operate.
The Kill-a-Watt is currently beneath $20 at Newegg.com and around $20 at Amazon.com.
