Sydney, Brisbane and the Gold Coast followed and they were more costly and at times controversial.<\/p>\n<p>\u00e2\u20ac\u0153However, just because circumstances mean the plants are spending long periods on standby, doesn\u00e2\u20ac\u2122t mean they cannot be used in other beneficial ways.<\/p>\n<p>\u00e2\u20ac\u0153This research shows that building more dams isn\u00e2\u20ac\u2122t necessarily the key to water security, but that it is better to consider what infrastructure is already there and how it can be used.<\/p>\n<p>\u00e2\u20ac\u0153For example, desalination plants can generate renewable hydropower for those times of peak demand in our cities by increasing supply during those hours.<\/p>\n<p>\u00e2\u20ac\u0153The benefits from this approach would include reductions in water costs for consumers and overheads for government and industry.\u00e2\u20ac\u009d<\/p>\n<p>Dr Sahin says that despite some predisposed views about the capacity and capability of desalination plants, they are a hidden asset that should be considered by government, industry and the water and power planners of our major cities.<\/p>\n<p align=\"center\">###<\/p>\n<p>Paper: http:\/\/www.sciencedirect.com\/science\/article\/pii\/S1364032116001817<\/p>\n","protected":false},"excerpt":{"rendered":"<p>IMAGE:\u00c2\u00a0Scientists say their findings can turn the tap on new options for urban water and energy management. view more Credit: Griffith University Renewable hydropower generated from desalination plants and other existing infrastructure would bring economic and environmental benefits to our biggest cities, according to new research from Griffith University.
