Energy Sources (Credo)
Energy Efficiency: Topic Page
When the world speaks about energy, invariably it speaks about energy supplies.
Alternative Energy: Topic Page
At the center of energy issues in the United States is the growing realization that in order to sustain this level of energy consumption, a transition away from fossil fuels to more reliable and sustainable sources is needed.
From The Columbia Encyclopedia
Fuel made from natural, renewable sources, such as new and used vegetable oils and animal fats, for use in a diesel engine.
Nuclear Energy: Topic Page
The energy stored in the nucleus of an atom and released through fission, fusion, or radioactivity.
Renewable Energy: Topic Page
Renewable energy is the energy produced by using natural resources that will regenerate in time. Primary sources of renewable energy are water, geothermal heat, wind, and sunlight. The energy produced by using different organic materials, such as wood, agricultural rejects, forestry residues, and urban solid waste (called biomass) is also regarded as “renewable.”
Solar Energy: Topic Page
Energy from sunlight is one of the world's most important natural resources. Fossil fuels and agriculture would be impossible without it. Solar power has been used for thousands of years, and the technology continues to evolve.
Water Power: Topic Page
Mechanical energy derived from falling or flowing water, e.g., rivers, streams, and the overflow of dams.
Wind Power: Topic Page
Harnessing of wind energy to produce power. Since the 1970s, advanced aerodynamic designs have been used to build wind turbines that generate electricity.
Dam: Topic Page
Structure built across a river to hold back a body of water (called a reservoir) in order to prevent flooding, provide water for irrigation and storage, and provide hydroelectric power.
Generator: Topic Page
In electricity, machine used to change mechanical energy into electrical energy.
Fuel Cell: Topic Page
Electric cell in which the chemical energy from the oxidation of a gas fuel is converted directly to electrical energy in a continuous process (see oxidation and reduction). MORE
Nuclear Reactor: Topic Page
Device for producing controlled release of nuclear energy.
Turbine: Topic Page
Rotary engine that uses a continuous stream of fluid (gas or liquid) to turn a shaft that can drive machinery.
GreenFILE This link opens in a new windowThis collection of scholarly, government and general-interest titles includes content on the environmental effects of individuals, corporations and local/national governments, and what can be done at each level to minimize these effects. GreenFILE draws on the connections between the environment and a variety of disciplines such as agriculture, education, law, health and technology. Topics covered include global climate change, green building, pollution, sustainable agriculture, renewable energy, recycling, and more. The database provides indexing and abstracts for more than 612,000 records, as well as Open Access full text for more than 9,100 records.
Environmental Studies (Gale in Context) This link opens in a new windowAn interdisciplinary portal to news, commentary, audio, video, primary source documents, images, conference reports, and statistics, supporting sustainability and environmental studies.
