One of our aims at the Planet Green website, is to try and provide people with tips and tricks for saving energy and water. Usually, we round up little household hints about how to save electricity or H2O. Most of the time we speak as if these two things were separate beasts. What you may not know is that saving electricity and saving water are actually the same thing.

Conversely, when you make electricity you can make fresh water. Development of large scale solar tower generating plants in the southwestern United States could meet the power demands of the entire country and, using the excess heat from the process, desalinate sea water to meet the needs for freshwater in Las Vegas, Los Angeles, San Diego, etc.
I think this article is misrepresenting the impact consumers can really have. Baseload power plants that consume most of the water used during power generation are not going to be turned off or use less water if we alter our daily demand by a few percent here and there. The only way that water use is impacted is through major changes in demand, or by retiring older plants in favor of more efficient plants, or retiring them altogether through major demand drop.
