What exactly is a carbon zero home?
A zero carbon home is one that returns to the National Grid as much power as it uses over the course of a year. Unless you plan on living somewhere with no heating, electricity or water, that means a zero carbon home will need to be kitted out with equipment for microgeneration – the production of energy on a small scale.
So, in come mini-wind turbines, solar panels and a wood pellet burner for generating energy. Meanwhile, to keep that precious energy in you will need clever, draught excluding construction with super-insulated walls, a geothermal heating system extracting heat from the ground and triple-glazed windows. You might also want a rain water collecting tank to supply the washing machine and toilets and to be connected to a reed bed sewage system for organically cleaning human waste.
