Sources is a web portal for journalists, freelance writers, editors, authors and researchers, focusing especially on human sources: experts and spokespersons who are prepared to answer Reporters' questions or make themselves available for on-air interviews.

This subject index is underpinned by an 'Intelligent Search' system which helps reporters focus their searches by suggesting additional subjects related to their search terms. For example, a search for "cancer" will suggest terms such as "chemotherapy", "melanoma", "oncology", "radiation therapy", "tobacco diseases" and "tumours", as well as topics that actually contain the word "cancer".

Energy conservation and Efficient energy use, efficiency measures reduce the demand for energy development, and can have benefits to society with improvements to environmental issues. Societies use energy for transportation, manufacturing, Lighting, illumination, heating and air conditioning, and communication, for industrial, commercial, agricultural and domestic purposes.

Non-renewable resources are signif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
