In a certain city, electricity costs $0.14 per kW - h. What is the annual cost for electricity to power a lamppost for 8.00 h per day with a 100. W incandescent light bulb versus an energy efficient 25 W fluorescent bulb that produces the same amount of light? Assume 1 year 365 days.. 100. W bulb: $ 25 W bulb: S Is the additional cost of the fluorescent bulb justified? A typical incandescent bulb costs $0.89 and lasts for about a year; a typical energy efficient fluorescent bulb costs about $3.49 and lasts for about 3 years. O yes /year no /year
