• – This paper evaluates the 4 articles on sustainable development –
• The First article is ‘How Much Water Does It Take to Make Electricity?’ Natural gas requires the least water to produce energy, biofuels the most, according to a new study (Jones, 2008).
• The second article is ‘Conserving Water many Times a Day: Low-Flow Toilets have Water-Saving Super Powers (Jones, 2008)’ which is one of the podcast segments in the Engineers of the New Millennium: The Global Water Challenge (IEEE Spectrum, September 2009), a special report on the Global Water Challenge.
• The third article is ‘Measuring Corn Ethanol's Thirst for Water’: Ethanol from corn consumes three times more water than previously thought. (McKenna, 2009).
• The fourth article is ‘Home Is Where 'Green' Can Start’ (Hoak, 2008).

Description

Water may seem to be everywhere, but for a rising portion of the world's population, there may soon be hardly a drop to drink -or to use for growing food, supporting industries and cities, and preserving life-giving ecosystems (Postel, 1997).
One of the environmental objectives for sustainable development is rational use of renewable resources, which if ignored could lead to either slow down or reversal of development. According to the classical definition given by the United Nations World Commission on Environment and Development in 1987, development is sustainable if it "meets the needs of the present without compromising the ability of future generations to meet their own needs.”
Water conservation is one of the issues, which needs to be seriously taken up in order to contribute to the sustainable development.
There are amazing innovations in the technology sector which provide the breakthrough in water conservation in basic areas which are generally ignored. I have picked four articles, covering innovation, researches and an investment report on water conservation.
