Energy touches our lives in countless ways and its costs are felt when we fill up at the gas pump, pay our home heating bills, and keep businesses both large and small running. There are long-term costs as well: to the environment, as natural resources are depleted and pollution contributes to global climate change, and to national security and independence, as many of the world's current energy sources are increasingly concentrated in geopolitically unstable regions. The country's challenge is to develop an energy portfolio that addresses these concerns while still providing sufficient, affordable energy reserves for the nation. The United States has enormous resources to put behind solutions to this energy challenge; the dilemma is to identify which solutions are the right ones. Before deciding which energy technologies to develop, and on what timeline, we need to understand them better. America's Energy Future analyzes the potential of a wide range of technologies for generation, distribution, and conservation of energy. This book considers technologies to increase energy efficiency, coal-fired power generation, nuclear power, renewable energy, oil and natural gas, and alternative transportation fuels. It offers a detailed assessment of the associated impacts and projected costs of implementing each technology and categorizes them into three time frames for implementation.

The America of the near future will look nothing like the America of the recent past. America is in the throes of a demographic overhaul. Huge generation gaps have opened up in our political and social values, our economic well-being, our family structure, our racial and ethnic identity, our gender norms, our religious affiliation, and our technology use. Today's Millennials -- well-educated, tech savvy, underemployed twenty-somethings -- are at risk of becoming the first generation in American history to have a lower standard of living than their parents. Meantime, more than 10,000 Baby Boomers are retiring every single day, most of them not as well prepared financially as they'd hoped. This graying of our population has helped polarize our politics, put stresses on our social safety net, and presented our elected leaders with a daunting challenge: How to keep faith with the old without bankrupting the young and starving the future. Every aspect of our demography is being fundamentally transformed. By mid-century, the population of the United States will be majority non-white and our median age will edge above 40 -- both unprecedented milestones. But other rapidly-aging economic powers like China, Germany, and Japan will have populations that are much older. With our heavy immigration flows, the US is poised to remain relatively young. If we can get our spending priorities and generational equities in order, we can keep our economy second to none. But doing so means we have to rebalance the social compact that binds young and old. In tomorrow's world, yesterday's math will not add up. Drawing on Pew Research Center's extensive archive of public opinion surveys and demographic data, The Next America is a rich portrait of where we are as a nation and where we're headed -- toward a future marked by the most striking social, racial, and economic shifts the country has seen in a century.

As the importance and dependence of specific mineral commodities increase, so does concern about their supply. The United States is currently 100 percent reliant on foreign sources for 20 mineral commodities and imports the majority of its supply of more than 50 mineral commodities. Mineral commodities that have important uses and face potential supply disruption are critical to American economic and national security. However, a mineral commodity's importance and the nature of its supply chain can change with time; a mineral commodity that may not have been considered critical 25 years ago may be critical today, and one considered critical today may not be so in the future. The U.S. Geological Survey has produced this volume to describe a select group of mineral commodities currently critical to our economy and security. For each mineral commodity covered, the authors provide a comprehensive look at (1) the commodity's use; (2) the geology and global distribution of the mineral deposit types that account for the present and possible future supply of the commodity; (3) the current status of production, reserves, and resources in the United States and globally; and (4) environmental considerations related to the commodity's production from different types of mineral deposits. The volume describes U.S. critical mineral resources in a global context, for no country can be self-sufficient for all its mineral commodity needs, and the United States will always rely on global mineral commodity supply chains. This volume provides the scientific understanding of critical mineral resources required for informed decisionmaking by those responsible for ensuring that the United States has a secure and sustainable supply of mineral commodities.
