000 watts per kilowatt) – (72 watts energy usage for halogen bulb × 1,000 hours × $0.13 per kilowatt-hour / 1,000 watts per kilowatt ) = $3.64 electricity cost savings of halogen versus standard bulb
fluorescent lasts 10000h. That means it takes 20 incandescent bulbs to replace the compact fluorescent, at a cost of $5 (the same as the price of the compact fluorescent bulb). However, over 10000h of operation, compact fluorescent use costs (at a rather typical 11 cents per kilowatthour)...
