A letter on Nov. 2 notes that the Chronicle's article on wind energy failed to mention the nearly $573 million that Invenergy had received in state/federal grants since 2010 as calculated by the website "Subsidy Tracker."

The writer then asks, tongue-in-cheek I'm sure, if that "sounds sustainable."  Based on the nearly $4.9 billion in subsidies that just one oil company (Exxon) received during the same period, again from Subsidy Tracker, the answer would have to be, "Well, it's a start!"
