Thinking Required; Uh Oh – Effective v Triggering DNA

Powerwall is mostly disruptive to the owner’s bank account. It solves no problem, but it does create new ones. In last year’s post, I assessed the cost of electricity storage via the 7 kWh Powerwall. Over the lifetime of the unit, the cost per kWh would be 11.7¢ per kWh, kWh and installation not included. In other words, the storage alone costs 11.7¢. Imagine if your…

Intelligencize This

By Energy Efficiency, Energy Rant No Comments
Last week ACEEE produced a webinar, “Intelligent Efficiency”.  I was late to the party but as I came online, an ACEEE guy, Neal Elliott was talking and the topic was intriguing – system-wide, holistic, intelligent efficiency.  I thought, hmm, maybe somebody read this entire series of rants and was possibly preaching from the gospels of the obvious. Next up was a guy from Schneider Electric and he gave a boring advertisement of – Schneider Electric.  Next was a guy from Johnson Controls to talk about what else – the Empire State building.  The  Empire State Building EE overhaul has been…
