2008 Annual Report “Everything Wind” SUMMER 2009 PAGE INTENTIONALLY LEFT BLANK 2 Mission The Wind Science and Engineering (WISE) Research Center at Texas Tech University distinguishes itself as an internationally recognized leader in research, education, and knowledge transfer on the effects of wind on people and the environment. Vision The Wind Science and Engineering (WISE) Research Center will continue to perform advanced and innovative multidisciplinary research to mitigate the deleterious effects of windstorms on the built environment, people (and their quality of life) and to utilize the beneficial effects of wind. Through research we provide educational experiences that prepare students for technical and leadership roles in private practice, industry, government and academia. We will be the place of choice for interested students, professionals and industry for wind-related research, education, outreach and community engagement. The Wind Science and Engineering (WISE) Research Center at Texas Tech University was established in 1970, following a tornado in Lubbock that caused 26 fatalities and more than $100 million in damage. Thirty-five years later, more than five thousand MW of wind power facilities has been developed in the region – with Lubbock situated at the geo-center of development and ranking. Texas is first in the nation in wind power capacity. The WISE Center focuses on research, education and information outreach and offers the only doctoral program in Wind Science and Engineering in the nation. The comprehensive and multidisciplinary research program aspires to exploit useful qualities of wind and to mitigate its detrimental effects. The Center offers a multidisciplinary education in wind science and engineering to develop professionals who are expert in wind-related research leading to the doctorate in Wind Science and Engineering. The Center develops information on windstorm disaster mitigation, wind power systems and other wind-related subjects for professionals and the public. The WISE Center has thirty-six faculty affiliates from twelve academic departments, three research associates, ten professional staff members, and twenty-one graduate students. Research and education awards totaled more than $3.5 million for calendar year 2008. The accomplishments and success of the Center through the past year are due entirely to the vision, dedication, hard work and collaborative spirit of our professional staff, faculty affiliates and students. It is through these combined efforts and commitment that the Center will continue to be successful in the future. Andrew Swift, Sc.D., P.E.

HIGHLIGHTS Thirty-five faculty members from twelve departments were affiliated with the Wind Science and Engineering (WISE) Research Center during 2008, from the fields of engineering, atmospheric sciences, economics, mathematics, architecture, and business. Figure 1 - Chancellor Kent Hance (left) and TTU President Guy Bailey accept a one million dollar grant from the Texas Workforce Commission to fund the Texas Wind Energy Institute. WISE currently has 21 students in the Ph.D. program, four students who completed their Ph.D. studies in 2008, and three Research Associates. The Texas Wind Energy Institute was created through the support of a $1 million Workforce Investment Act Statewide Activity Fund grant from the Texas Workforce Commission (TWC). The grant will be used to develop curriculum and to prepare students to meet the workforce needs of the rapidly growing wind power industry in Texas. The Texas Wind Energy Institute is a partnership between TTU and Texas State Technical College (TSTC) and will house the Wind Energy Education program. Researchers submitted thirty-one wind-related research proposals during the year for a total of more than $6.2 million in potential funding. To date, sixteen proposals for wind-related research received funding in 2008 for a total of more than $3.7 million; six (total: $1,276,977) are pending. 7 Faculty members provided sixteen special presentations and served on twenty-two professional committees at the local, regional and national levels. Wind Science and Engineering Center affiliates authored thirty-two articles published in refereed journals and books, and nineteen publications in proceedings of conferences. Texas Tech University’s College of Outreach and Distance Education hosted a short course in "Introduction to Wind Power Systems: Technology and Economics” in June (in Lubbock) and in October (in Sweetwater) through the Center. Focused towards people in government, land owners and others who are interested in learning more about wind power, the courses attracted 44 participants.

The first of two state-of-the-art Ka-Band Radar mobile Doppler radar trucks was finished in 2008, and is now in use in the field. The second is still in progress. (See Figure 3-5.) 10 Figure 4 – Graphic of Inflow Jet Velocity – the patches of color reflect the speed of the wind in the atmosphere. (Courtesy of Jerry Guynes.) Figure 5 – Christmas photo-op of 2008 Ka-Band radar truck with faculty, staff and students taken at the American Wind Power Museum. 11 Figure 6 - The growing Mesonet network provides information throughout the region now comprising thirty-seven counties in West Texas and Eastern New Mexico, represented by the online map above. Source: http://www.mesonet.ttu.edu/site_info.html The West Texas Mesonet, an array of automatic weather stations throughout the region, has expanded to fifty-five Mesonet stations in 37 counties located in both Texas and New Mexico. The network also includes one radar wind profiler, one acoustic wind profiler, and one upper-air sounding system. The newest station is near St. Lawrence, Texas. Also, the expanded Mesonet now offers archived data products in specialized formats available to companies or individuals for purchase, and averages 41,000 hits per day. For the month of June 2008, the site had 2.133 million 12 hits (av.:71,000 hits/day) with one day in particular receiving nearly 160,000 hits. Website: www.mesonet.ttu.edu. Wes Burgett, along with the West Texas Mesonet team members Brian Hirth and Ross Williamson and Faculty Director Dr. John Shroeder were awarded the 2008 Larry R. Johnson Special Award from the National Weather Association. This award is presented to an individual or group to recognize unique events or extraordinary accomplishments that significantly contributed to operational meteorology. It was presented at the NWA conference in October 2008. (See figure 7 below.) Figure 7 - (Left to right) – Wesley Burgett of the West Texas Mesonet; National Weather Association President John Scala, and Jeffrey Vitale from the National Weather Service in Lubbock, receive the Larry R. Johnson Award at the 2008 NWA awards banquet in Louisville, Kentucky. WISE received an initial $60,000 from the International Sign Association (ISA) and the Outdoor Advertising Association of America (OAAA) to determine the wind load capacity of signs, such as the ones in front of restaurants or gas stations. The research is being conducted due to changes to the 2006 sign code by the American Society of Civil Engineers which increased the wind load requirement from previous years. The construction of twenty-four mobile Stick-Net probes has been completed. The goal is to have 48 mobile Stick-Nets. These platforms were deployed throughout the Great Plains by students and faculty from Texas Tech University to collect highresolution meteorological data within super-cell thunderstorms. In 2008, the Stick- 13 Nets were also deployed in Hurricanes Dolly, Gustave and Ike – this represents the first full-scale hurricane deployments of this observing technology. (See Figure 8.) Figure 8 - Ian Giammanco, an IGERT Fellow with the WISE program, explains the StickNet program to visitors. Entirely student-produced, the technology can be set up by two people in three minutes or less enabling it to be quickly assembled during high-wind events. National Storm Shelter Association (NSSA) headquarters are located within the TTU Wise Center under the direction of Dr. Ernest Kiesling. NSSA added a Senior Compliance Officer, Oscar Scott, to oversee shelter installation/building compliance issues. There were 63 NSSA members for 2008 in comparison to 53 members in 2007. The new “Installer Member” category has increased to seven members to date. South Plains Association of Governments was awarded a Hazard Mitigation Grant Program to provide rebate for 50% of shelter cost up to a grant of $2,500. The NSSA worked to get the International Code Council/National Storm Shelter Association Standard on the Design and Construction of Storm Shelters approved by the American National Standards Institute (ANSI) to offer new guidelines for community shelters and residential safe rooms. One feature of the new standard increases minimum wind resistance requirements in the event of rare but strong winds. 14 The NSSA is currently filing to trademark the NSSA logo both in Texas and with the Federal registration. Finalization of the process is expected to take six to twelve months. Ernst Kiesling and Larry Tanner contributed to updates and revisions of the FEMA 320 publication- “Taking Shelter from the Storm: Building a Safe Room for your Home or Small Business” and the FEMA 361 publication - “Design and Construction Guidance for Community Safe Rooms.” Larry Tanner served on the Mitigation Assessment Team (MAT) in studying the damage of Hurricane Ike. Thirteen Debris Impact Tests were conducted in collaboration with companies including Ground Zero, Tugraz, and Lite Tech Wall Systems. The Debris Impact Testing Facilities staff conducted approximately twelve tours including one for Texas Senator John Cornyn and Congressman Henry Bonilla and Charlie Stenholm .(See figure 9 below.) Figure 9 - WISE faculty, staff and students post with Texas Senator John Cornyn during his tour of the Reese research facility in October. 15 II.

THESES/DISSERTATIONS COMPLETED No Picture Available DESIGN AND CONTROL OF AN INTEGRATED WINDWATER DESALINATION SYSTEM FOR AN INLAND MUNICIPALITY Dennis Noll, Ph.D. (2008) ABSTRACT: Current water pricing standards do not take economic responsibility for dwindling potable water aquifers. By only incorporating financial, but not true economic costs of this scarce good, serious depletion of these often slow-recharging groundwater resources has occurred in many areas in the United States. Aquifer depletion for some areas looms on a 50year or closer horizon, and many municipalities in the Southwest and elsewhere face potential distress due to lack of sustainable fresh water levels. In order for these towns to remain economically and physically viable, alternative water resources must be found. Texas Tech University is working with an affected West Texas inland municipality to evaluate the technology and economics of a full-scale, integrated wind powered-reverse osmosis system. The system will be applied to produce potable water from a brackish aquifer at the average rate of three million gallons per day, and will be controlled by an algorithm that controls the dispatch and use of the generated electricity. The algorithm will process streaming real-time water use and electrical load data in combination with wind speed measurements in order to determine the best use of the energy produced by a turbine array; either for water purification or for displacing conventional power on other municipal loads. The algorithm will also explore the potential of using treated water as a form of energy storage for the system. The end product of this system is a water purification process that will utilize a brackish water aquifer for all of the city’s potable water needs, and wind power for all associated reverse osmosis and other electrical loads. 39 MODELING OF LOW-LEVEL JETS OVER THE GREAT PLAINS: IMPLICATIONS FOR WIND ENERGY Brandon Storm, Ph.D. (2008) ABSTRACT: Low-level jets (LLJs), wind maximums centered 100 - 1000 m above the ground, are common features observed over the Great Plains of the United States. An accurate understanding of LLJs has many implications for the wind power industry. For example, LLJs can increase wind speeds at turbine heights, which in turn leads to an increase in energy. However, these same high speed winds created by LLJs can create large amounts of stress on the turbines, causing fatigue issues over time. Without a proper understanding of the LLJ, accurate estimates of the wind speeds at hub height, which are needed for wind resource assessment and forecasting projects, are very difficult to obtain. When assessing a particular location for placement of a wind farm, it is common within the wind power industry to use towers that do not reach the height of the turbine's hubs. Therefore, the hub height wind speed has to be estimated by using lower-level wind speed measurements (60 m or lower) and assuming a simple power law relationship. However, to obtain an accurate estimate of the hub height and higer wind speeds, one has to know what shear exponent value to assume. The presence of LLJs causes the shear exponent to be significantly higher than what the industry currently assumes. The Weather Research and Forecasting (WRF) model can simulate the low-level wind speed and frequency of LLJs over the Great Plains in a manner that it could be used to estimate the shear exponent over the Great Plains. On the other hand, an investigation of the LLJ climatology compared to observational studies indicates that the WRF model has room for improvement in forecasting the speed and height of LLJs. The WRF model predicts the low-level wind characteristics (speed and directions distributions) over a year’s time period with some skill. Therefore, a framework coupling the WRF model with a wind resource analysis program commonly used within the industry, the Wind Atlas Analysis and Application Program (WAsP), was developed. It was found that the WRF model could be used as input into WAsP with confidence, and shows prospect in being able to replace tower observations for completing preliminary resource assessment projects. This would allow the wind power industry to complete site assessment projects in a timely and economically efficient manner. 40 WIND DIRECTIONALITY: A RELIABILITY-BASED APPROACH Rolando E. Vega-Avila, P.E., M.ASCE, Ph.D. (2008) ABSTRACT: A methodology to reliably combine the effects of building aerodynamics and site climatology as a function of wind direction is needed to quantify the effects of wind directionality. It has been previously noted that considerations of wind directionality would result in risk-consistent, safer and more economical designs of buildings. In this doctoral exposition, the author makes use of data collected at Texas Tech University to define such methodology. The West Texas Mesonet is used to define the mean and extreme climate in west Texas while the Wind Engineering Research Field Laboratory provides the aerodynamic data in representation of low-rise buildings. A novel approach to separate extremes in nonhurricane regions is presented by assuring that events are independent using atmospheric pressure data and using information from the continuous wind data sets. The aerodynamic extreme directional assessment of the low-rise building is based on estimates of pressure coefficients of building components representing the design of cladding and lateral and vertical forces representing the design of portal frames. The current standards of minimum loading of structures in the United States and Canada take into account wind directionality by saying that there is a reduced probability of the extreme winds not necessarily coming from the most aerodynamically vulnerable direction. However, no systematic reliable measure is available to date to establish such reduced probability using extreme value distributions. In the research presented in this investigation, the combination of two databases (climatic and aerodynamic) to estimate wind directionality effects corroborate the assumptions in the standard and provide a methodology to quantify the factor in a reliable way. Results indicate that while the use of a wind directionality factor is absolutely not recommended for structural building components, if non-structural components get a discount of approximately 20% in the wind load, roughly 16% of the building population in open terrain will see a wind load in its lifetime that exceeds the specified design. Due to the large uncertainties in the wind directionality factor produced by: (1) unknown random building orientations and (2) large probabilities of exceedance in the load coefficient specified in the standard, the true directionality issue should only be accounted through detailed analysis and not by a wind directionality reduction factor. The use of an aerodynamic exposure correction is recommended instead to account for the reduced average peak wind load that is seen in terrains where the exposure is rougher than the modeled open exposure for which loading coefficients are given in the standard. 41 ` AN ANALYSIS OF THE COST OF HAZARD MITIGATION PLANNING POLICY IN LOCAL AND REGIONAL GOVERNMENT Andrea Gamret-Jackman, Ph.D. (2008 ABSTRACT: According to the Disaster Mitigation Act of 2000 (P.L. 106-390), and the Federal Emergency Management Agency’s (FEMA) subsequent Interim Final Rule (44 CFR Parts 201 and 206), local governments are required to write and gain approval for a Hazard Mitigation Plan (HMP). Once the plan has been approved by FEMA, the authoring jurisdiction(s) is eligible to apply for and receive federal grant funding through the Hazard Mitigation Grant Program (HMGP) and the Pre-Disaster Mitigation Grant Program (PDM). A pilot study conducted on the completion of HMPs revealed that over 90% of plans were completed multijurisdictionally, although approximately two-thirds of local governments in the United States remain without plans. An examination of disaster management literature reveals that planning activities and specifically the role of multi-jurisdictional cooperation in these activities, remains poorly understood. The analysis presented in this dissertation includes that of the pilot study, the creation of a conceptual model of emergency management in the United States, and the results of a statistical analysis of the cost to single and multi-jurisdictional planning entities for the creation of a HMP. The results of the analysis indicate that the cost of a HMP varies significantly depending on the population of, and the frequency of natural hazards experienced by the planning jurisdiction. The recommendation is made that multijurisdictional planning efforts be highly favored over single-jurisdictional ones for costreducing purposes, particularly for those jurisdictions which experience a low frequency of natural hazards. Questions regarding the role of multi-jurisdictional entities in the mitigation of natural disasters are also recommended for potential avenues of future research. 42 Figure 17 – Jeff Livingston, Unit Manager at the Reese Technology Center, explains the more technical aspects of the wind/water desalination project to JROTC visitors from Amarillo.

The Wind Science and Engineering (WISE) Research Center continues to attract minorities and females to its program. The program currently sponsors three minority and five female PhD candidates, and six of the summer interns were minorities and/or female as well. The Center hosted the McDonald-Mehta Lecture Series which invited six nationally renowned wind-research scholars: Dr. Jim McDonald (TTU – retired), Dr. Jianming Yin (Marine Technologies, GA), Dr. Vilas Mujumdar (NSF, VA), Dr. Bill Hooke (AMA), Dr. Michael C. Robinson (NREL, Golden CO) and Mr. Mike Hightower (Sandia National Labs). Other visitors to the center included Ronald T. Eguchi, President and CEO of ImagaCat, Inc (CA) who gave a talk on “Earthquakes, Hurricanes and other Disasters: A View from Space”; Professor Qingshan Yang from Beijing Jiaotong University who gave a presentation on “An Overview of Structures for the 2008 Beijing Olympic Games”, and Dr. Erik L. Peterson of Technical University of Denmark who covered the topic of “Scientific and Technical Challenges for the Advancement of Wind Energy.” Goal 2: Research and Academic Excellence: Be a world leader in integrated multidisciplinary research and education. WISE has the only Wind Science and Engineering Ph.D. program focused in wind science and engineering in the nation. The program was approved by the Texas Higher Education Coordinating Board (THECB) in 2007. WISE currently has 21 students in the Ph.D. program. Four WISE students have completed their Ph.D. studies in 2008, and the Center has three Research Associates at the current time. Researchers pursued sixteen funded wind-related research projects during the year. Thirty-five faculty members from eleven different academic departments were affiliated with the Center during 2008, from the fields of engineering, atmospheric sciences, economics and geography, mathematics, geospatial technology, architecture, and business. Faculty members were invited to give sixteen special presentations and served on twenty-two professional committees at local, regional, statewide and national levels. Affiliates in the Wind Science and Engineering Center authored thirty-two articles published in refereed journals and books, and nineteen publications in proceedings of conferences. WISE has hosted two short courses focused on the “Introduction to Wind Power Systems and Economics” reaching 44 participants, many of whom were in government positions or land owners. The first of two state-of-the-art Ka-Band Radar mobile Doppler radar trucks was finished in 2008, and is now in use in the field. The second is still in progress. 49 The Center (in collaboration with the TTU Water Resources Center) has partnered with the city of Seminole to lead the way in cutting-edge wind-driven water desalination focused on making brackish water available to municipalities for drinking water. Thirteen Debris Impact Tests were conducted in collaboration with national and international companies. The Center has partnered with Texas State Technical College to develop curricula and a program in Wind Energy Workforce development and education. Graduate certificates and an undergraduate degree program in Wind Engineering are under development. Goal 3: Engagement: Build community connections to enhance the quality of life. The Texas Wind Energy Institute was created through the support of a $1 million Workforce Investment Act grant from the Texas Workforce Commission. The grant is being used to develop curricula and to prepare students to meet the workforce needs of the rapidly growing wind power industry in Texas. The Technician certificate curricula have been completed by Texas State Technical College. The Texas Wind Energy Institute is a partnership between TTU and Texas State Technical College (TSTC). (See goal #2.) The Center is collaborating with a local municipality (the City of Seminole) to address wind-driven water desalination to enhance the dwindling water supply in the region. (See also Goal #2). The VORTEX tornado simulator was completed at Reese Technology Center and is capable of producing 1 m tornado vortex for research and application studies using wind tunnel models. The StickNet probes (i.e. rapidly deployable wind/weather instrument platforms) continue to be deployed to collect high resolution meteorological data within supercell thunderstorms. In 2008, the StickNets were also deployed in Hurricanes Dolly, Gustave and Ike – this represents the first full-scale hurricane deployments of the observational technology in a full-scale hurricane. WISE faculty served on the Mitigation Assessment Team (MAT) for Hurricane Ike. Twelve tours were conducted at the Reese Research facilities including one for Texas Senator John Cornyn and one for both Congressman Henry Bonilla and Charlie Stenholm. The National Storm Shelter Association (NSSA), headquartered within the Center, is currently filing to trademark the NSSA logo in both Texas and with the Federal registration. WISE faculty continue to contribute to national emergency management guidelines and publications to include revisions of this year’s FEMA 320 publication “Taking Shelter from the Storm: Building a Safe Room for your Home or Small Business” and the FEMA 361 publication, “Design and Construction Guidance for Community Safe Rooms”. NSSA membership grew fifteen percent from 2007 to reach 63 NSSA members in 2008. 50 Efforts of the WISE Research Center and the NSSA faculty were instrumental in the approval of the International Code Council/National Storm Shelter Association Standard on the Design and Construction of Storm Shelters. Approved by the American National Standards Institute (ANSI), the new guidelines are for the construction of new community shelters and residential safe rooms. South Plains Association of Governments was awarded a Hazard Mitigation Grant Program to provide rebates for 50% of the cost up to a total of $2,500 per storm shelter. Goal 4: Technology: Use latest technology in research and delivery of information. The Center has completed the construction of the first of two Ka-Band mobile Doppler radar trucks to gather high resolution wind data. (See also Goal #2.) WISE Research Center students and staff continue to develop the StickNet project, a portable network of instruments used to collect atmospheric measurements around severe thunderstorms and hurricanes. (See also Goal #3.) The growing Mesonet network now has 56 stations across thirty-seven counties in West Texas and New Mexico. The newest station is near Saint Lawrence, Texas. Additionally, the expanded Mesonet now offers archived data products in specialized formats available to companies or individuals for purchase, and averages 41,000 hits a day on its website: www.mesonet.ttu.edu. For periods of record-breaking inclement weather, the website has had more than 150,000 hits in one day. Goal 5: Partnerships: Build and enhance strategic alliances with external entities. A collaboration was initiated with the International Sign Association and the Outdoor Advertising Association for America for a $60,000 research project to determine the wind load capacity of signs, such as the ones in front of restaurants or gas stations. The research is being conducted due to changes to the 2006 sign code by the American Society of Civil Engineers which increased the wind load requirement from the previous year. A partnership between Texas Tech University and the Texas Workforce Commission has led to the creation of the Texas Wind Energy Institute through the support of a $1 million Workforce Investment Act grant. (See also Goals #1 and 2.) WISE Faculty have collaborated with State Farm Insurance for further hurricane research. The Center continues to foster strategic alliances with the National Renewable Energy Laboratories and with Sandia National Laboratories wind energy programs in the area of wind turbine performance and reliability. WISE is a founding member of the Texas Lone Star Wind Energy Alliance, a collaboration of wind energy university and industry programs. The Center, through the Texas Wind Energy Institute, has partnered with the Wind Coalition, a wind energy advisory group, to validate developing wind energy curriculum. 51 Goal 6: Human Resources and Infrastructure: Maintain and enhance faculty and staff, and experimental facilities and work space. Renovations of the Reese facilities have continued, the West Texas Mesonet continues to expand (now up to 56 stations), and the Vortex Tornado Simulator is completed. Goal 7: Tradition and pride: Maintain and enhance national and international reputation. Wes Burgett, along with West Texas Mesonet team members Brian Hirth and Ross Williamson, and Faculty Director, Dr. John Schroeder, received the 2008 Larry R. Johnson Special Award from the National Weather Association. This award is presented to an individual or group “to recognize unique events or extraordinary accomplishments which significantly contributed to operational meteorology”. The Center hosted the McDonald-Mehta Lecture Series which invited six nationally renowned wind-research scholars: Dr. Jim McDonald (TTU – retired), Dr. Jianming Yin (Marine Technologies, GA), Dr. Vilas Mujumdar (NSF, VA), Dr. Bill Hooke (AMA), Dr. Michael C. Robinson (NREL, Golden CO) and Mr. Mike Hightower (Sandia National Labs). (See Goal #1.) Other visitors to the center included Ronald T. Eguchi, President and CEO of ImagaCat, Inc (CA) Professor Qingshan Yang from Beijing Jiaotong University, and Dr. Erik L. Peterson of Technical University of Denmark (See also Goal #1.) There were three hurricane deployments to Hurricanes Ike, Gustave, and Dolly involving approximately ten team members from the Center. The Center generated at least five news releases in 2008 with at least one leading to coverage outside the region in Jackson, Mississippi. Additionally, there were visits from two international companies, one television station from Japan, and one independent British television production company. There was also coverage on various events from the local media. Goal 8: Institutional Advancement and Accountability: Establish fiscal stability. Research funds for 2008 were from a variety of sources and totaled more than $3.7 million for the year. The Center anticipates similar figures for the following year supporting its goal of fiscal stability within the university. Researchers submitted thirty-one proposals for wind-related research during the year for a total of more than $6.2 million in potential funding. Sixteen proposals for wind-related research received funding in 2008 for a total of more than $3.7 million; six (total: more than $1.2 million) are pending. Commentary: The Center continues to build on its strong foundation and 38-year history. This report illustrates the continued expansion and evolution of the Center providing additional research thrust areas, such as wind power systems and advanced wind research capabilities (e.g. Ka Band Doppler radar, Sticknet etc.) leading to new research and educational opportunities for students and faculty while serving the region, state, and 52 the nation. The new Ph.D. program provides the next generation of leaders and decision makers in wind-related fields enhancing our goal of research and academic excellence while the formation of the Texas Wind Energy Institute for wind energy workforce development expands the Center’s commitment to outreach and education. Implementation Plan: Facilities and space are presently adequate with offices on campus in the Civil Engineering building and with space at the Reese Technology Center to include the field site and building numbers 250 and 350. The research and education potential in the area of wind energy is potentially quite large, but to capitalize on these opportunities will require the hiring of several new faculty. Grants and endowments would facilitate these hires, and are being sought through development and other avenues both within and external to the university. Long-term projects and goals require long-term and stable sources of revenue. Presently, the inflation-adjusted State Line item support for the Center is decreasing substantially each year. In addition, Federal Congressionally Directed Projects, an important element in funding over the past decade, is becoming increasingly unstable and problematic, adding to future resource uncertainty. Securing longer term, stable funding is a priority and the Center is actively seeking endowments for scholarships, professorships, and chairs by working with the Development Office, alumni and corporate partners. Finally, Center personnel and facility resources continue to provide important support for the faculty who seek competitive grants and contracts, which remain an important element in securing resources. 53 Figure 18 – A selection of the historical collection of windmills at the American Wind Power Center in Lubbock, Texas. 54 PAGE INTENTIONALLY LEFT BLANK 55
