Money must have already been spent on alternate resources, or study on, I mean with wmd's thats the way things have evolved, its a progression, if past scientists and inventors engineers and mathematical genius's hadnt done what they did we wouldn't have the advances we have now, theres always a downside
Actually I think the point of depature was when they started harnessing electricity. The generation of high voltage high cyclic rate electricity was neccesary for transmittion lines to cities and factories.
Farms ran their own systems (wind power) low voltage direct currents. Today we have these technologies tday in RV and boats (sail) which have developed to meet the portable demand just as we developed desk top computers then lap tops with comparable capablitities. Look at the igloo coolers with DC plug in to run of the auto battery, these units will heat or cool within a 30 degrees of the ambient temperature.
Alterations could produce a window ac/ heat unit for auto or home, the wind generator for sail boats will work hanging of the side of the highrise apartment as well as the mast of a sail boat. They have low volt / current microwaves, etc that could be adapted to the individual home apartment usage. The use of propane motors and refrigerator/freezer would have less impact while these gases are renewable from waste decomposition.
