This week on BBC One we will see Dick Strawbridge and his 22-year-old son, James, head to Bath, Bude and the Wirral, as they continue their journey across the UK to help others make their lives greener. Using their first-hand experience of converting their derelict farmhouse into an eco-home in the first series of It’s Not Easy Being Green, Dick and James offer practical assistance to those looking for a more sustainable way of life.

Two recent graduates living in Bath are keen to give their scruffy city garden the green treatment. Inspired by the greenhouse made from recycled materials and heated with a sustainable heatsink system at Dick’s farm, Duncan and Steve have grand plans for something similar to maximise their crop of home-grown vegetables.

With no budget, they search the web for freebies and, fortunately, on Freecycle – the sustainability website – they find a greenhouse. James arrives in Bath to help them source materials to construct the heatsink which will keep the greenhouse warm.

In the Cornish resort of Bude, the Moriarty family are planning to build an eco-campsite with as many environmentally friendly facilities as possible. They want showers powered by solar energy, composting loos and livestock to graze between the tents. Dick and James assess how feasible their plans are.

One project not going quite to plan is the Keenan family’s new-build eco house on the Wirral. This £750,000 property will be entirely powered by a large wind turbine and all the water will be recycled from a massive rainwater harvesting tank. Project manager Helen Keenan is dismayed to find that the huge tank may have been wrongly positioned.
