From RenewableEnergyWorld.com (Jerome Muys/Van Hilderbrand):
One approach to reducing greenhouse gases has been more reliance on renewable energy. But energy projects, both conventional and renewable, typically require large amounts of water. That means the long-term physical and legal availability of water resources will play an important role in the siting of renewable energy facilities.
In the U.S., federal programs such as the Endangered Species Act and the push to reserve water rights for parks, wilderness areas and tribal lands are further limiting water availability for development.
To remedy this, two trends are emerging. First is an effort to co-locate renewable energy projects with water reuse, reclamation and desalinisation facilities. Second is a growing interest in new water conservation technologies being developed in Israel and other countries which have a long experience of dealing with water shortages.
