Sulfur hexafluoride (SF6) is an inorganic, colorless, odorless, non-flammable, non-toxic extremely potent greenhouse gas, and an excellent electrical insulator.SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, it is poorly soluble in water but quite soluble in nonpolar organic solvents. It is generally transported as a liquefied compressed gas. It has a density of 6.12 g/L at sea level conditions, considerably higher than the density of air (1.225 g/L).
All electric buildings were quite popular in the mid 1960s at the dawn of the nuclear age but they fell out of popularity during the 1970s. It's not particularly efficient to convert fossil fuels into electricity compared to burning them directly. It's a different calculation if your generating from renewables though. Also, most American homes are wired at too low of a voltage to be really efficient at using electricity to do very energy intensive tasks well - like quick, instant on heat generation or spinning large electric motors. 240 volt outlets are relatively rare and almost nobody in their home has 480 volt 3 phase electricity. If people had 480 volt 3-phase in their homes, then things like instant-on electric water heaters and electric cars would be a lot more pratical -- but higher voltages require greater separation of the wires, with more insulation, and greater issues with sparks due greater ability of electricity to jump.
Some electricity customers in New York’s Hudson Valley support hydropower harnessed from running water close to home. The idea is similar to farm-to-table, except for electricity instead of food: green-minded customers supporting an area renewable resource. And smaller hydro plants like those run by Harry Terbush and Sarah-Bower Terbush have a different way to keep their turbines turning. “It’s community energy, and it allows us to sell directly to customers, and allows them to get a little more benefit of what’s in their backyard,” said Sarah Bower-Terbush.
The story of electric power is a story of urbanization. The major battlefield of the famed “War of Currents”—an electric arms-race and propagandized power struggle between Thomas Edison, Nikola Tesla, and George Westinghouse—was Manhattan. But to set the scene, let’s start in Paris, the City of Light.
