Power Solar panels and a roof-mounted wind turbine supply power

Power Solar panels and a roof-mounted wind turbine supply power to the house. Excess energy is sent to the local electricity grid, which means that other homes can use eco-friendly electricity.

Bedroom The bedroom is kept warm by wall and ceiling insulation. It is cooled with a ceiling fan, which uses less energy than air-conditioning. Skylights and energy-efficient lightbulbs are low-emission ways to light the room.

Bathroom A low-flush toilet and low-flow showerhead help to save water. The sink, bath, and shower water, along with rainwater from the roof, drain into a gray water system. Gray water can be used for flushing the toilet and watering the garden and pot plants.

Kitchen The washer, fridge, freezer, dishwasher, and oven are energy efficient. The dryer is also energy-efficient, but an outside clothesline can be used on fine days. The cabinets, flooring, and benchtops are made from recycled or renewable materials.

Flooring The floors are made of renewable materials, such as bamboo, and heated from beneath by under-floor pipes. The pipes pump hot water from a solar heating system in the greenhouse.

50% of home electricity can be provided by a roof turbine..
