[RE-wrenches] Solaredge Storedge

[Rebekah Hren]

I hear you loud and clear Kirk. On the one hand it is pretty cool to see so
much interest in battery-based systems, on the other hand the level of
misinformation being spread around is frightening and time-consuming to
combat.

There is a Bill McKibbon article in the New Yorker this week where he
unfortunately, loudly and clearly, repeats the Tesla marketing spiel. He
reports from the CEO of Green Mountain Power  -  "Powell was excited by its
low price: three thousand dollars, far below what analysts had predicted,
and low enough that her company could immediately begin installing it for
customers, especially those who wanted backup electricity in case a
snow-storm disabled the grid."

Here's  a link the article:

The more I re-read this the angrier I get, and honestly it would be awesome
to send a group co-signed letter to the New Yorker refuting this inanity
and telling Bill M to do his homework. Send me an email off-list if anyone
wants to follow-up.
