Kevin, freedom without responsibility is licentiousness, which is immoral.
There is no Constitutional right to burn one's childrens' and grandchildrens' limited fossil fuel supply for the sake of one's own amusement, nor does anyone have any basis for moral standing to proclaim otherwise.
Electricity, meanwhile, is a different story, as it can -and will more and more- be generated from wind, sun, and uranium. We've solved the safety issues with nucelar reactors -four or five designs for advanced reactors to choose from. The French have solved the nuclear waste issue -recycle the stuff and stretch the world's supply of nuclear fuel by a factor of six or more. We should be going full steam ahead (ha) with a major nuclear construction program. A solid foundation of nuclear will also enable the maximum use of renewables notably wind, which can supply up to 20% of grid capacity (any more and the intermittency issue causes destabilization of the grid). Add another 30% from solar, cut back overall consumption via improved efficiency, and we've solved our energy problems.
Add the new Toshiba high-capacity instant-charging batteries, and you can drive all over creation if you choose. But between now and then, patience is not only a virtue, it's a necessity.
Air conditioning is the single largest issue with regard to electricity consumption, and is the focus of major engineering efforts that also include whole-building design changes. I don't have specialist knowledge in HVAC so I'll leave that topic to others who may.
As far as the entire vintage appliance field is concerned, a typical large top-loading washer consumes about 1/4 of a kilowatt-hour to do a load, which is practically nothing. A similar case applies to most of the appliances that folks here collect and restore: actual energy consumption is minimal. So the "sustainability cost" for the "entertainment value" of keeping the old machines whirring is minimal, unlike SUVs.
By the way, SUV is an oxymoron. A sports car is small, light, nimble on its wheels, quick through the corners, and sticks to the road like a treefrog on a window. A utility vehicle is a truck: a real truck, a creature of hard work with the muscles to prove it, and not a frill anywhere to be seen. An SUV is neither, but rather like a confused person whose goals are unclear and whose motion is neither graceful nor deliberate.
