What are my savings in replacing one 65 Watt Incandescent light bulbs with one 23 Watt Compact Fluorescent Light (CFL)... running it for one hour at $.14 kWhr cost (from my monthly utility bill)?

Note: The 23 Watt CFL is a 65 Watt Incandescent equivalent. Since CFLs keep improving it may be closer to 18 Watts. They just keep going down.

While daily savings appear small, they add up over time. What if I replaced 8 light bulbs and run them for 6 to 8 hours per day? It begins to really add up!
