Wind Power: A Cooling Breeze On The Watergy Nexus?

Via CleanTechies, an interesting report on how wind power affects the watergy nexus:

“Besides being good for the environment for reducing emissions and being a renewable source of power, wind energy also uses less water than other types of power generation, stated the American Wind Energy Association recently.

This is an important aspect of energy generation since around 40% of the world’s population already lives in water-stressed areas; with a growing population estimated to reach nine billion by 2050, pressure on water reserves will only get more intense. In fact, global water demand is expected to outstrip supply by 40% by 2030 under a business-as-usual scenario.

According to research carried out by Vestas Wind Systems, wind power generation actually conserves water and can help alleviate water shortages, a sharp contrast with conventional fossil fuel and nuclear power plants, which make up 78% of global electricity production. These use water for cooling and condensing the steam that drives the turbines. Wind power generation requires practically no water.

The U.S. Department of Energy estimates that 20% of wind power in the U.S. power system by 2030 would save as much as four trillion gallons (15 trillion liters) of water, or the equivalent to the annual consumption of more than nine million U.S. citizens.

Fortunately, some of the water-challenged regions of the world are suitable for wind power generation, which could provide them with an ideal alternative to their energy demands, one that is carbon-free and simultaneously reduces water consumption.”

About This Blog And Its Author
As the scarcity of water and energy continues to grow, the linkage between these two critical resources will become more defined and even more acute in the months ahead.  This blog is committed to analyzing and referencing articles, reports, and interviews that can help unlock the nascent, complex and expanding linkages between water and energy -- The Watergy Nexus -- and will endeavor to provide a central clearinghouse for insightful articles and comments for all to consider.

Educated at Yale University (Bachelor of Arts - History) and Harvard (Master in Public Policy - International Development), Monty Simus has held a lifelong interest in environmental and conservation issues, primarily as they relate to freshwater scarcity, renewable energy, and national park policy.  Working from a water-scarce base in Las Vegas with his wife and son, he is the founder of Water Politics, an organization dedicated to the identification and analysis of geopolitical water issues arising from the world’s growing and vast water deficits, and is also a co-founder of SmartMarkets, an eco-preneurial venture that applies web 2.0 technology and online social networking innovations to motivate energy & water conservation.  He previously worked for an independent power producer in Central Asia; co-authored an article appearing in the Summer 2010 issue of the Tulane Environmental Law Journal, titled: “The Water Ethic: The Inexorable Birth Of A Certain Alienable Right”; and authored an article appearing in the inaugural issue of Johns Hopkins University's Global Water Magazine in July 2010 titled: “H2Own: The Water Ethic and an Equitable Market for the Exchange of Individual Water Efficiency Credits.”
