ReNew Issue 129
Community energy special
This issue takes a tour of community solar projects happening in Australia right now, as well as community-owned microgrids, disruptive social innovations and what it takes to get a community wind farm up and running. It also includes our efficient hot water systems buyers guide, a look at microinverters, EVs and how they affect demand management, small hydro in Tassie, a DIY computer monitor from a dead laptop, making caravan fridges more efficient, building with hemp, the basics of inverters and much more!
Issue 129 October-December 2014 is out now! As always, ReNew comes overflowing with articles to satisfy both the technically and the not-so-technically minded. Regardless of whether your interest is photovoltaic cells, recycling, or even environmentally responsible building techniques, there is something for you in this issue.
