Assuming the energy comes from burning coal, calculate the amount of CO2 (in kg) that can be saved by replacing a 60W incandescent bulb with an LED bulb over the course of the bulb's lifetime, using the information below: An average LED replacement bulb equivalent to a 60W incandescent bulb consumes 10W of power and is expected to work for 15,000 hours. On average, when burning coal, the amount of energy released per g CO2 released is 2.05 kcal/gCO2- A Watt (W) is 1 /s 1 cal = 4.184 )
