Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. 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, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density ofGet price

Wind power in Russia - Wikipedia

Wind power in Russia has a long history of small-scale use, but the country has not yet developed large-scale commercial wind energy production. Most of its current limited wind production is located in agricultural areas with low population densities, where connection to the main energy grid is difficult. In 2006, Russia had a total installed wind capacity of 15 MW. Russia is estimated to have a total potential of 80,000 TWh/yr for wind energy, 6,218 TWh/yr of which is economically feasible.
