Eco House Challenge - S1 E1

2. Water Torture

For twenty-four hours both families have lived without energy, water, transport or waste removal, and now, Glenn arrives to turn their water hotspot back on and set a sustainable reduction level. With the water challenge in place, it's time for Eco Coach Tanya Ha to start her coaching and she quickly zeros in on the families' un-eco behaviour.

3. Emission Impossible

After living in darkness for a week, the Edwards family finally pass the water challenge and their energy hotspot is returned. Relieved and upbeat, they move on to the next hotspot challenge - a sixty percent reduction in their energy use.

4. Driving Me Crazy

This week, the Shepherd family face their toughest trial yet. The transport challenge is underway, and for university student Jesse, giving up his car is a huge sacrifice. Over at the Edwards household, the transport challenge rules spark debate.

5. Waste Not Want Not

It's the penultimate episode of the series and the Edwards are struggling to pass the transport hotspot challenge. All out of solutions, Eco Coach Tanya decides to exploit a loophole in the challenge which results in the Edwards meeting their transport target.

6. Final Countdown

The families have just two days to go and nerves are starting to fray. Have the Shepherds taken too big a risk putting their kids in control? Over at the Edwards home, Spike has taken a leaf out of Cam's eco book and he too has drawn up a master plan.
