### Generic Electrical Energy Cost Calculator

Lighting: To find out how much your lighting costs, enter the number of bulbs you use, then choose a bulb type. (A common incandescent bulb is 60 (we have stated 60 as typical), 75 or 100 watts, and a standard fluorescent bulb is 40 (we have stated 40 as typical) or 60 watts. An outdoor spotlight or floodlight may use 150 (we have stated 150 as typical) to 500 watts. Light bulb wattage is usually printed right on the bulb. We have provided six sets of data entry fields and a wide array of lamps types for the likely event you must use different types of light bulbs. You may have to run the calculator several times for a total.
