1. Masdar is a city that is just outside the most unlikely of locations-the oil-rich Abu Dhabi. It runs without carbon, and it only uses natural energy. The UAE decided to build it because they rely on the oil wells, and the officials are well aware that the oil wells will eventually run dry, leaving them with no choice, but to resort to renewable sources of energy. 2. In Masdar, the "greywater' gets recycled. The water from washing machines, sinks, baths, and showers gets purified and recycled so it can be used again. In order to minimize wastage of water or electricity, the designers eliminated faucet handles and light switches inside buildings. Instead, everything is motion activated! Officials say that this feature has reduced electricity consumption by 51%, and water usage by 55%. 3. Some people think Masdar will never be completed because of how much it costs to build it. Over the past six years, it has only been completed about 15%. The author believes that the experiment is still successfull because the UAE has come up with many clever ideas that other cities can use. 4. I think that the thing that would help our city most is to get the "greywater" recycled and to make the faucets and light switches motion-activated.
