Neither terribly in-depth nor very useful, this book is mostly filled with tips that ought to be obvious. For those who have never before heard of the idea of reducing consumption and who have no idea about their own environmental impact, this might be a good introduction, but mostly it reads like a high school workbook. I imagine it's part of the publishing foundation's educational materials, for which it probably serves its purpose, but as reading matter it leaves much to be desired. This might be a good book to read with younger kids to introduce them to the ideas inside, but for adults looking for a real guide to reducing consumption, it's a bit on the fluffy side.
A neat little guidebook to saving energy and money.
