NEWClean Wind Energy Tower, Inc. Selects First Site in United States to Build Green Renewable Energy Downdraft Tower
ANNAPOLIS, Md., March 22, 2012 -- Clean Wind Energy Tower, Inc. (OTCBB: CWET - News), (the "Company"), announced today that the Company selected a site located in San Luis, Arizona, to pursue the construction of their innovative green renewable energy Downdraft Tower Facility. The Downdraft Tower has the capability of being operated with virtually no carbon footprint, fuel consumption, or residual waste. This technology will generate clean, cost effective and efficient electrical power without the damaging effects caused by using fossil or nuclear fuels, and other conventional power sources.
The San Luis location incorporates plans for two (2) Downdraft Towers and a component parts Assembly Plant. As designed, the Company anticipates that each Downdraft Tower could generate enough electricity to power up to 1,600,000 homes using the guidelines set forth in the California Statewide Residential Appliance Saturation Study, 2004. As an independent power producer of clean renewable energy, the Company will not be selling power directly to consumers but rather to the grid.
Ronald W. Pickett, President and Chief Executive Officer, stated, "San Luis is an ideal location for Clean Wind Energy to build our first alternative energy facility because this region of the southwest United States provides the proper weather profiles, proximity to the power grid, and other ingredients beneficial to the operation of a Downdraft Tower, and has been previously targeted as a prime region for alternative energy projects. I am enthusiastic about locating our Downdraft Tower in the United States because not only is this a breakthrough source of clean alternative energy, it will bring significant employment opportunities and economic stimulus to San Luis and a number of U.S. industries. We anticipate that during the Downdraft Tower's construction phase, 2,500 construction and transportation jobs and 1,000 manufacturing jobs will be created. Once placed in service, each Tower should generate 1,000 permanent jobs."
In early February 2012, Clean Wind Energy Tower, Inc. applied to the United States Department of the Interior for permission to lease a parcel of property located in San Luis, Arizona, suitable for the development and construction of our first Downdraft Tower. The Company also applied to the Bureau of Reclamation for a temporary use permit to enable access to the site to evaluate a variety of issues including zoning, performing a preliminary geological survey and a general site evaluation along with other environmental assessments.
After notification by the Bureau of Reclamation that Clean Wind Energy Inc. could proceed with the local zoning process and site evaluations, the Company applied to the City of San Luis, Planning and Zoning Commission for entitlement to build two (2) Downdraft Towers and a component parts Assembly Plant.
In furtherance of this process, a City of San Luis, Public Information Hearing has been scheduled for March 29th, 2012, and the City of San Luis, Planning and Zoning Commission has scheduled a hearing for April 10, 2012.
About Clean Wind Energy, Inc.
Clean Wind Energy, Inc., a wholly owned subsidiary of Clean Wind Energy Tower, Inc., has designed and is preparing to develop, and construct large "Downdraft Towers" that use benevolent, non-toxic natural elements to generate electricity and clean water economically by integrating and synthesizing numerous proven as well as emerging technologies. The Company's core objective and focus is to become a provider of clean efficient green energy to the world communities at a reasonable cost without the destructive residuals of fossil fuel, and to help broker the chasm between both, while continuing to generate innovative technological solutions for today and tomorrow's electrical power needs. In addition to constructing Downdraft Towers in the United States and abroad, the Company intends to establish partnerships at home and abroad to propagate these systems and meet increasing global demand for clean water and electricity. Clean Wind has assembled a team of experienced business professionals, engineers and scientists with access to the breakthrough energy research upon which this technology is founded and the proven ability to bring the idea to market. Clean Wind Energy, Inc. has filed several patents that the Company believes will further enhance this potentially revolutionary technology. Clean Wind Energy, Inc. is based in Annapolis, MD, and is traded on the OTCBB under the symbol 'CWET'. For more information visit www.cleanwindenergytower.com

Comment from Denis Bonnelle about:
“Solar chimney project in Arizona: an energy budget basic check”
A paper, published in October 2011, in the review “Sun & Wind energy”,
provides useful information about the La Paz solar chimney project in Arizona.
Denis Bonnelle checks the basic figures which are mentioned by EnviroMission in this article:
• the delivered design power will be 200 MW
• the plant will get a 60 percent capacity factor
• hence, the annual delivered energy should be: 1 GWh/y

Bay Area in Wuhai Jinsha Inner Mongolia built a 200 kW solar hot experimental demonstration power plant.
Wuhaijinsha Bay for the construction of solar chimney power plant has unique advantages
(1) sufficient energy sunlight for a long time.
(2) resource-rich desert, the sand may help to solve the heat storage medium.
(3) construction methods and building materials can be obtained locally, just glass building materials, cement and steel.
(4) geographical location and convenient transportation.
(5) has unique climatic conditions, is a temperate continental arid climate, dry and windy throughout the year, helping improve the air flow speed.
Therefore, Wuhai Jinsha Bay voted for the construction of desert air solar power stations.
Currently Wuhai Jinsha Bay Area voted to build a 200 kW solar chimney power station demonstration technology.
The project planning capacity of 27.5 MW, accounting for a total of desert 2.780.000 m2, a total investment of 1.38 billion Yuan.
Work will be done in three phases:
the first phase
of the project in May 2009 - December 2010 year in building 200 kW demonstration solar chimney power generation, accounting for desert area 40.000 m2, investment of 1 000 million;
the second phase
of the project in February 2011 - December 2011, building 2.2 MW solar chimney power plant system, accounting for desert area 220.000 m2 investment 110 million yuan;
the third phase
of the project in January 2012 - December 2013, construction of 25.1 MW solar chimney power plant system, accounting for desert area of 2.510.000 m2, investment 1.26 billion Yuan.
The CD-ROM of the Proceedings of the 2nd International Conference on Solar Chimney Power Technology, held on Bochum – Germany, 28-30 september 2010 is available for the price of 40.00 €.
