A CLAPBOARD house in Cape Cod is very different from a one-room mud-brick hut in the Indian state of Orissa, but making them into green homes involves a similar approach: using as little energy as possible to meet the occupants’ needs. But in the developing world the impact of new technology can be far more transformative.
Consider the cooking of food, which is usually done by burning wood or dung. Typically 80% of the fuel’s energy is wasted, and the resulting smoke pollutes indoor air and contributes to more than 1.6m deaths a year, according to the World Health Organisation. But using a carefully designed stove to enclose the fire and direct heat into the pot, fuel consumption and pollution can be reduced dramatically.
