Sulfur hexafluoride: The truths and myths of this greenhouse gas

insulating gas is damaging to the environment: TRUE. Along with CFCs, HCFCs, HFCs and PFCs, Sulfr hexafluoride is an industrial gas that doesn't exist naturally in the atmosphere and so impacts the radiation balance, contributing to climate change. insulating gas is the energy industry"dirty little secret": FALSE. Sulfr hexafluoride is certainly no secret in the Norwegian energy industry. Its use is highly regulated, and many of its users are working together to share experience and come up with viable alternatives Sulfr hexafluoride is used in wind turbines: TRUE. Sulfr hexafluoride is used not in the turbine itself, but in the switchgear that controls the current generated by the turbine. But there is nothing unique about wind turbines. There are no viable alternatives to sf 6: PARTLY FALSE. Bodies including the European Union are known to be considering a ban on Sulfr hexafluoride at low-to-medium voltage levels in the future.

5 Reasons Why I Don’t Have Solar Panels on My Roof...Yet

Not Yet Economic…For MeBig Changes ComingUnrealistic Lifetime ExpectationsSocial Un-FairnessUncertain Utility Standby ArrangementsSolar installation costs have fallen to less than $4/Watt and a few states have reached ‘grid parity’ — meaning that power from those panels costs the same as that provided by the local utility grid. As far as I can tell, Colorado, where I live, isn’t one of those states, even though we have plenty of sunshine. That’s because the economics depend so heavily on various tax and rate incentives, which vary from state to state. It’s not just a matter of cheap panels. Panels are expected to drop to less than $2/Watt by 2020, and by 2017, Colorado will probably reach true grid parity, again assuming incentives stay the same. That’s only two years away — another reason to wait a bit before pulling the trigger.Get price
