Can we save the planet? To find out, two ordinary suburban households have been wired to monitor their every eco move. The challenge starts with a bang. Without warning four environmental hotspots, energy, water, transport and waste removal are shut down until further notice. Over several weeks, while still living their normal lives, the families must radically reduce consumption and learn to live sustainably. For the Edwards; a large, frugal family led by logistically minded ex-commando Spike and no nonsense working Mum, Mary, it’s going to be tough. With seven in the family, including their elderly grandmother, Nonna, consumption is high. Meanwhile the Shepherds; an affluent family headed up by financially obsessed businessman, Cam and sharp witted domestic workhorse, Shauna, love the good life. Going without is not going to be easy for these consumer addicts. But help is at hand. The families’ Eco Coach is modern day greenie and scientific number cruncher, Tanya Ha. Together they have just weeks to do what we all must do in just a few decades. If they can pass the Eco House Challenge and help save the planet…so can we.
