This is a book on how the U.S. and other governments have changed their thinking about energy issues over the past four decades, a change triggered by increasing concern about the role of fossil fuels in global warming and climate change, greater awareness of the risks of nuclear power, and the emergence of viable renewable energy sources. It will help understanding of how this change came about in the United States from the unique perspective of a well-placed participant and observer. It will enhance understanding of the global energy transition that is finally getting underway in the second decade of the 21st century at an accelerating, even dizzying, pace. The book’s main purpose is to illustrate how the U.S. government moved along its winding path to where it is today in getting ready for a renewable energy future. Target audiences are the young people who will inherit the transition and shape its future, those in government who currently shape our public policies, and those colleagues, friends, and family members who lived through many of the times and events discussed in the book.
