When you think about it, $30 a month plus 15 cents per kilowatt hour is a pretty darn good price for being connected to the electrical grid. A kilowatt hour is about 3/4th of a horsepower, produced over an hour of highly reformed energy that can be power even the most delicate of electronics or turn over large motors with ease and efficiency.
A typical house has a 200 amp feed in it, which means you have roughly 150 horsepower worth of electricity at your disposal to distribute throughout your house. Unlike a gas motor, it doesn’t cost you anything at idle, and your pay directly proportional to your use. You can flip a switch on and get instant torque or power from electricity.
Most electric appliances are quite efficient to converting electricity into useful work – almost all the waste is on the generating plant side, not on the consumer side. The generating plant maintains the turbines, buys the fuel, and disposes of ash. No smoke in your backyard or noxious fumes.
When at off-grid living, the truth is electric generated on site is far more expensive and less flexible than grid power. It might be much cleaner and the cost of use is fixed entirely by your capital costs – and is reduced each kilowatt you consume. But it’s still not as cheap and flexible as grid power.
Anyone who has traveled to the United Kingdom has probably marveled at the imperial bulk of the standard U.K. wall plug. With three chunky, rectangular pins, the design at first glance seems almost ridiculously inefficient, especially compared to the svelte footprints of the U.S. and European wall plugs, which manage to get juice to your electronics in under half the space.
But first impressions can be deceiving. In fact, as Tom Scott explains in a new video, the U.K. wall plug is a design classic that is substantially safer than any other plug design on Earth.
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.
