ReNew Issue 136
This issue of ReNew cheers on Australian-made research and production with an eye toward sustainability. We also look at strawbale building workshops and case studies of people who love their houses ‘built of straw’. We explore the important issue of keeping textiles out of landfill and cover ways to reconnect with nature in the city. ReNew 136 highlights a world-first trial of a household battery system network on Bruny Island and how forecasting of both energy usage and the weather can improve battery economics. You’ll also find tips on what to consider to ensure you buy or build the most efficient computer possible, as well as an update on our popular eco-paints buyers’ guide. Finally, we report on the very exciting project just completed by the ATA where we helped advise and connect a remote Aboriginal community with investors to install a 36kW solar system offsetting about 10 tonnes of CO2 each year. Plus lots more!
Issue 136 is hot off the press and full of advice for your sustainable home. As always, ReNew comes overflowing with articles to satisfy both the technically and the not-so-technically minded. Regardless of whether your interest is building with strawbales, finding out what to do when your solar feed-in tariff expires or buying eco-paints, there is something for everyone in this issue.
ReNew 136 has ‘Australian-made’ as its focus. Inside you’ll find:
