Good topic, Meg! My experience with breweries and solar is complicated: a) they are staunch advocates of sustainability, but b) they are EXTREMELY sophisticated in the use of heat exchangers are other ways to recapture waste heat, and, c) they are inundated with calls from solar salespeople. Here's something I wrote on the subject: http://2greenenergy.com/2014/01/14/microbreweries-sustainability/.
Yes, this is a brilliant summary, to be sure. Hi, Stephen. Keep up the good work. Btw, here's a post I wrote on your podcast about biomass the other day: http://www.2greenenergy.com/biomass-in-the-news/1501/. And, perhaps more on topic, one of several I've written on solar thermal: http://www.2greenenergy.com/solar-thermal-bruce-allen/1064/.
Again, great stuff.
