ReNew Issue 134


Energy efficiency special

This issue delves into the world of energy auditing and how to go about reducing your home’s energy consumption. We examine the rebound effect, where energy efficiency can lead to energy use that offsets some of the savings – or does it? We take a look at energy efficiency measures renters can undertake to get their energy bills under control, and review what you need to know about appliance Star ratings. We also cover the economics of adding batteries to a solar system, large-scale solar projects happening around the world, women working in the renewables arena, creating a cool refuge from the summer heat, simple DIY projects + much more! This issue includes our updated Solar Panel Buyers Guide with the lowdown on what to look for when buying your next solar panels.
