Not counting the walking time to/from the bus stations. Absolutely. I actually tested it on Monday this week. I carpool with a friend every day. It was his drive that day, he had an emergency and I had to find a way back to the car pool lot myself. I had a ride available to me, but decided to give public transportation a try as an experiment. It cost me $3.50 and took about 2 hours to get back to the car. By car for the same trip it costs me $2.00 in gas (I know, depreciation, maintenance and insurance aren't included) and it takes me 20 minutes. 2 hours ONE WAY vs. 20 minutes? I don't think it's even a question. > > Instead of releasing 80% of the energy devoted to lighting as > > heat, release 5% (or whatever the incandescent vs. LED breakdown > > is). > > This may be counterintuitive, but fluorescent lights are about twice as > energy efficient as LEDs. This again is a case where people don't consider the energy used to MAKE the bulb, and then dispose of it properly. With those numbers thrown in an incandescent bulb doesn't seem that bad anymore...
