Green=smoke and mirrors. Most alternative fuels sound good, but when you break down the energy and economics of them they’re big losers and not a replacement for petroleum-based fuels.
Same thing with ethanol, the price on the sign at the gas station is lower than the 100% gas stations, but when you total the up the decreased mileage you get, it isn’t a good trade off, but plenty of people are tricked into thinking they got a good deal.
As was said waaaay back in the 70’s when ethanol first started to appear in motor fuels, “stretching your fuel supplies by using ethanol is like stretching your hamburger supplies with Filet Mignon.”.........
