No, I know this solution may not be possible for unfair sex (men) or women whose spouses are not earning. But some kid from MIT or IITs can invent a technology to convert marital bickering into energy. You did not understand. Let me explain. When you have argument with your spouse , you produce sound whose decibel level is quite good. Sound is a form of energy. And though energy can not be created, one form of energy can be transformed into another form. So some machine which converts this sound into electrical energy will help a lot. You come home, yell at your wife/husband, she/he will will shout back at you and this will definitely go on for quite some time. All this while the aforesaid machine is silently getting charged with electrical energy. You finish your fight and go to sleep. Morning your machine is all charged ready to be packed in your vehicle and drive it. If you and/or your spouse snore at night that is even better. Please remember, I have a patent over the idea.
