" The prospects for electric power in the twenty-first century can be summarized in a single word: growth. Electricity consumption, both worldwide and in the United States, has doubled since 1980. It is expected, on a global basis, to about double again by 2035. And the absolute amount of the doubling this time will be so much larger, as it is off a much larger base. An increase on such a scale is both enormous and expensive. The cost for building the new capacity to accommodate this growth between now and 2035 is currently estimated at $10 trillion—and is rising. But that expansion is what will be required to support what could be by then a $130 or $140 trillion world economy.1 Such very big numbers generate very big questions—and a fierce battle. What kind of power plants to construct and, then, how to get them built? The crux of the matter is fuel choice. Making those choices involves a complex argument over energy security and physical safety, economics, environment, carbon and climate change, values and public policy, and over the basic requirement of reliability—keeping on not just the lights but everything else in this digital age. The centrality of electricity makes the matter of fuel choice and meeting future power needs one of the most fundamental issues for the global economy. "
