  1. Is it financial or is it men are discouraged from having a family, women are encouraged to chase only the best men and put off starting a family until its too late for them? I dunno, but its all included. HOWEVER.... I know its sustainable for me to grow two acres of cattails, use the roots to produce ethanol, the leftovers to produce methane, and that is how I power my old muscle cars. Local production, local use. I make it here and run my vehicles on it. Costs me about 40 cents a gallon, biggest cost is yeast and the enzymes that convert starch to sugar, and cleaning supplies. One acre of wild cattails makes around 1000 gallons of fuel. (2x to 4x the yield per acre of corn) One acre of cultivated cattails that are fed effluence from livestock runoff, can produce 10,000 gallons of clean burning fuel, WHILE CLEANING THE WATER flowing past them.. All you need is some tanks for fermentation, a source of starch/sugar, some water that can be reused, plastic tubing, copper or pvc for a still, and a boiler that can be cleaned easily. Also some space because things take up room and trying this in your apartment is going to limit how much you can make, and the quality of fuel. Everything left over after fermentation can be fed to livestock or used for methane production, which can power the boilers, generators, and be used for cooking. Methane is essentially natural gas you can produce easily and cheaply. No drilling or digging required. Running ethanol is simple and requires no special parts to run in your vehicle, no expensive tanks (like hydrogen does) and it has a great many other uses besides fuel. Every internal combustion engine can run on ethanol, with some changes to the tuning. Methanol is the corrosive one, ethanol is nowhere near as corrosive as methanol. Ethanol is simply vodka, moonshine, whiskey, bourbon, wine, beer... Literally anyone can do it, cavemen made it, its thousands of years old tech... however the stills I use are vastly more efficient than a moonshiner's still. I built them myself and they make 180 to 190 proof fuel in a single run. The only emissions from ethanol and methane are Co2 and water, which comes from plants already growing on the surface of the earth, not dredged up from the ground.. Put the Co2 in a greenhouse and get the benefits from plants needing less water, producing more high quality food, and growing faster. If you want to go off grid, be self sufficient/sustainable, and actually do something to help the environment, getting into ethanol production can be very beneficial. There is a lot more you can do that I am not talking about here, its not a one trick expensive pony.
