renewable energy sources

Presents a scientific view at how carbon dioxide affects climate change, explaining how a buildup of carbon dioxide in the atmosphere is contributing to global warming, and discussing various energy innovation methods and techniques that can be used to improve and safeguard the future of the planet.

Identifies the energy-related challenges of the early twenty-first century, looks at how the United States and other nations are responding to the problems, and provides a selection of related reference information, including case studies, primary source documents, biographies, statistics, and a chronology.

Examines the complex issues surrounding current energy sources and alternative energy options focusing on fossil fuels, bioenergy and geothermal energies.

Profiles the fossil fuel crisis and discusses why Americans ignore the warnings about depleting fuel supplies, how alternate sources of fuel can be developed, what the fuel crisis means for society, and other related topics.

Provides an overview of career opportunities in the twenty-first century that are related to green or renewable energy, and discusses education and training.

Describes the alternative methods of generating energy instead of using fossil fuels, including solar power, wind power, and biofuels, and speculates on the future of alternative energy.

Discusses some of the problems related to the world's dependence on fossil fuels for energy, and describes five renewable energy resources, including the sun, biomass, wind, and water.

Investigates the production and use of methane as an energy source, covering the costs, risks, potential roadblocks, and benefits.

Worldwide, over 1.3 billion people lack access to electricity and another 1 billion have unreliable access, with enormous consequences for their everyday lives. In addition, many countries spend a high share of their GDP on fossil fuel imports, making them dependent on foreign energy supplies and vulnerable to price fluctuations. The burning of fossil fuels pollutes local environments, endangers the health of citizens, and exacerbates global climate change.
