Auckland Council reveals that Aucklanders are discovering new and simple ways to lower their carbon footprint and save money using tools from Live Lightly. One family changed all their lights to LED’s and saved $400 per year on power bills. Another found that conserving water – a small change – added up to big savings in both water and power bills. A free Home Energy Audit Toolkit (HEAT kit) from a local Auckland Library is the best start to figure out where the biggest savings might be for your particular situation.
