As debates over energy resources continue to dominate public discourse, it is crucial that the American public have access to objective and authoritative information on such matters. This well-designed and thoughtful website from The National Academies contains helpful interactive features, short quizzes, complete academic reports, and a glossary. First-time visitors can learn about the potential of different energy sources in the "Sources" area, which includes overviews of how the sun, electricity, fossil fuels, and nuclear power can be harnessed most efficiently. Moving on, the "Uses" area includes summaries of how Americans currently use energy in the home, workplace, and industry. The "Understanding Efficiency" area provides two useful activities that illustrate how energy can be delivered efficiently to the home and on the road. Finally, visitors can sign up for email updates and learn more about upcoming events sponsored by The National Academies.
