Denis Du Bois, editor of "Energy Priorities" magazine, commented on the realistic and comprehensive coverage of the book. However, he suggests that "The Clean Tech Revolution" is not an explanation of the technologies and how they work, nor is it an analysis of energy or environmental policy. Policy is complicated and the authors avoid discussing it in detail. Little discussion ties the various clean technologies together and a "single-minded American focus" dominates. There is very little on the influence of mass transit and urban planning in Europe and other progressive regions. The chapter on water focuses on filtration, which is already an area of considerable opportunity, affecting even "green" industries, such as photovoltaics manufacturing.
