I drive a Bolt now. I average about 4.6 miles per kwh and I've traveled about 4,200 miles since the end of December or 600 miles per month or 20 miles per day. I'm retired. This means I have to save about 4.3 kwh using LED bulbs over incandescent bulbs on a daily basis. Each bulb, if it replaced

Excuse me, i think Bob said 50 lights, 5h, 75w so that is in the order of 20kWh, not 150. So it is maybe twice as much as avg, not 10x. With the 15+ kWh Bob can save with LEDs, he can drive approx 50-60 miles a day. BTW, Lee, you are not alone. My daily commute is 35 mi round trip. Cor. On Sat, J

The calculation was for 50 bulbs 5 hours a day. In my house, I leave 3 basement lights, and one shop light on all the time (hard to get to the switches). And outdoors, there are 4 lights on dawn-to dusk (say 10 hours). So, do the math. The 4 bulbs on 24/7 are the same as 19 bulbs for 5 h ours.

To make the math work, I should have said, "the average house with teenagers leaving all the lights on for 5 hours a day". [50 lights times 60W saved times 5 hours a day = 40 miles daily EV charging] I stand by my numbers when corrected to a house that leaves most of their lights on all evening a
