According to the U.S. Energy Information Administration, only 10 percent of the energy consumed in the United States in 2015 came from renewable sources. The five major consumers of energy are electric power at 39 percent, transportation at 28 percent, industrial at 22 percent, residential at 7 percent, and commercial at 4 percent. This engaging resource explores the issues of energy use, policy, and possible new sources. Chapters address the current status of the world''s energy use and the role of governments in addressing energy concerns; the impact of voluntary conservation and the transition to energy efficient technology; the current use of alternative energy sources; and the future of energy from where we stand.

Hundreds, even thousands, of years before Europeans arrived in North America, American Indians had made their homes here. These many groups adapted to the varied lands and climates of what would later become the United States. Each group developed its own culture and history. When settlers from Britain, France, Spain, and Russia arrived, the newcomers interacted with American Indians in different ways. Some engaged in trade, while others tried to enslave American Indian peoples or to take over their territories. Many conflicts arose as the different groups fought over land and resources. The colonization of their land changed the lives of American Indians forever. Explore the history of the many American Indian peoples who predated the United States. Track the important events and turning points that shaped their cultures both before and after the arrival of European explorers, traders, and colonists.
