In addition to reading this book, if you ever have a chance to see Jeremy Rifkin present on the Third Industrial Revolution and the Intergrid, please, take that advantage (it is well worth it!). Mr. Rifkin has wonderfully distilled and delivered a compelling vision of the world ahead in a sustainable, clean, distributed and collaborative energy model. This book brings a perspective on past industrial revolutions and points to technological processes and connects many of the dots of the myriad & disparate energy technologies and how they will coalesce and be deployed in the years ahead. It is no surprise that Mr. Rifkin has been advising many global governments not only on what the vision is but how to take advantage of the economic opportunity since 2007. It remains disappointing that the political climate in the US continues to inhibit a unified energy policy... and thus puts the US at a severe competitive industrial disadvantage vis a vis countries like Germany, China, Singapore and many others that have been listening... and which understand the rich landscape of commercial opportunities ahead... and the significant detriment to those countries which aren't proactively adjusting to those threats (& opportunities) ahead. There are several books which work well as companion pieces to Rifkin's TIR: "That Used To Be Us", "Reigniting Fire" and "The Quest" are some of them. Based on documented job creation in Germany from the solar sector alone, US economists recently projected that, had the US followed a similar solar/ renewable energy vision, we would likely see over 2million related jobs created. Energy Efficiency carries its own highly compelling ROI. We have clean fuels in our labs now that have an unsubsidized cost per BTU less than that of Natural Gas, and without the carbon emissions. Coupled with the smart grid, these new technologies will allow the highly efficient energy storage that unlocks Rifkin's Intergrid: the sustainable, distributed, adaptive, interactive, renewable energy Intergrid. Rifkin's TIR & Intergrid outlines a compelling vision for the future, but one that is already dawning in labs across the world and beginning to be implemented where there are true leaders. The book drives home its points repeatedly... but the points are well worth paying attention to.
