Most people are unaware that environmental problems such as climate change can be easily avoided, at a profit, through the intelligent application of appropriate technology. The handbook describes how to achieve this goal in the residential field. The first book in North America to provide a detailed carbon accounting of a family's carbon emissions and how to reduce them, it systematically analyses energy costs and evaluates which measures yield the highest returns for the environment and the pocketbook. It provides answers to questions such as: Which measure is more effective: putting solar panels on your roof, or buying a hybrid car? Where do I need to invest first: in high-efficiency shower-heads, or solar tubes? Is a $500 fridge that uses 800 kWh of power per year a good buy? The book allows individuals to quickly and accurately assess which products are a good deal and which aren't. It systematically analyses residential carbon emissions and energy costs and prioritises solutions based on highest carbon reductions and monetary returns, yielding results that are often surprising. The book enables readers to dramatically reduce their carbon emissions - far below the levels targeted under the Kyoto Protocol. At the same time, readers implementing the recommendations will save an average of $15,000 in energy costs over the next five years.
