1. LED light bulbs are replacing incandescent light bulbs because over 90% of the energy consumed by an incandescent bulb goes in to producing heat, not light. The 14-watt LightKing LED costs $1.32 in electricity per year. The 60-watt LightKing incandescent bulb gives the same amount of light but costs $6.09 in electricity per year. How much could be saved per year by using 25 of the LED bulbs in a house?​
