Slide 2

Presentation Outline United States and World Energy Outlook Renewable Energy Background Kansas' Place with Energy/Renewables Wind Energy Basics Wind Energy Economics Issues/Factors Affecting Wind Energy Next Steps

Slide 3

Energy Policy - Kansas Major Objective Improve add up to framework productivity concerning all vitality assets Improved end-utilize proficiency benefits Resource Allocation (fossil fills and renewables) Environment (air emanations, water quality, manageability) Economics Energy-benefit Ratio (EPR)

Slide 4

Community/State Dialog "What's in Your Energy Policy?" Kansas – The Net Energy Importer "Kansas kept on bringing in a record measure of its vitality in 2003. This pattern, which started in 1997, has seen vitality utilization rates outpace vitality creation, requiring noteworthy measures of cash to acquire vitality assets from out of state." (Kansas Energy Plan – 2004, page 5) What are suggestions for our economy (nearby & state)? Kansas just can not deliver itself out of this with customary assets Will regardless we need to keep on exporting $$$ or would we be able to change this? Will we be held to value volatilities? What are the ecological ramifications? Maintainability (financial, natural, vigorous, and so on.)? Different contemplations?

Slide 5

Community/State Dialog "What's in Your Energy Policy?" Kansas - The Sustainable State New vitality/control (in many structures) from vitality proficiency and in-state renewables What are suggestions for our economy? Lower, higher, or levelized costs after some time? Value instability viewpoints with current sources would to some degree be expelled Begin to control our own particular fate What are suggestions for our condition?

Slide 6

Energy Issues – Quick Overview World vitality utilization anticipated that would increment 58% by 2025 United States utilization anticipated that would increment 40% by 2025 Petroleum conjecture to stay as the essential wellspring of vitality to 2025 and will increment in creating nations altogether There are "X" routine vitality sources that are diminishing to be connected to "Y" populace; consequently the need to create and actualize new sources What will be the impact on Kansas? Star dynamic or responsive? Reference: World Oil Outlook

Renewable Energy Resources

Slide 13

Common Criticisms & Misconceptions of Renewable Energy "They are excessively diffuse" That can be something worth being thankful for "They can never meet a noteworthy bit of our vitality needs" Depends on their end-utilize "They cost excessively" Consider all expenses and particularly life-cycle costing "It takes more vitality to make renewable vitality equipment than it ever delivers" Not genuine and renewables give a supportable EPR "We have heaps of fossil fuel" We do, yet will we have the capacity to get to it and would we truly like to utilize it

Slide 14

Reasons for Renewable Resources Biomass, Wind, Solar 3 "E's" vitality → practical vitality benefit proportion (EPR) household supply versus imports (control of our own predetermination) natural → even from a pessimistic standpoint, a "shut carbon" cycle, best case scenario, no carbon outflows no sulfur dioxide discharges no overwhelming metals monetary → petroleum exchange lopsidedness as of now ~$90 billion every year; anticipated to $206 billion in 2025 ($2001) lost "open door cost" with exchange awkwardness implies loss of capital in US → loss of interest in renewable vitality → loss of occupations → loss of feasible vitality future

Slide 15

Energy Balance of Wind Energy Throughout its 20-year lifetime, the normal turbine produces 80 times more vitality than the sum used to assemble, keep up, work, disassemble and scrap it (EPR = 80+). By and large, it takes just 2 to 3 months for a twist turbine to recoup all the vitality required to assemble and work it. EPR of switchgrass for CHP = 7-10 EPR of grain-based ethanol = 1.34

Slide 16

Wind Energy

Slide 17

Kansas Wind Energy Potential Kansas' wind vitality assets are huge Kansas is usually connected with being the 1 st to 3 rd "windiest" state in the US The state has been seriously immature (for an assortment of reasons) Difference between what "blows", what can be financially created, and end-utilization of wind This is amazingly basic to the "accomplishment" of wind vitality ventures

Slide 18

Wind Power Isn't Perfect Wind Power yield changes after some time Wind Power is area subordinate Wind Power is transmission-subordinate for attach into the matrix Wind Power has natural effects (professional/con) Wind Power can just meet some portion of the electrical load

Slide 19

Wind Energy Basics Physical & Engineering Aspects

Slide 20

Wind Power Equation P = ½ * air thickness * Area Swept by Rotor * Wind Speed 3 P = ½ * ρ * A * V 3 Power in the wind is corresponded 1:1 with zone and is to a great degree delicate to wind speed (the cubic enhances the power fundamentally) If the wind speed is twice as high, it contains 2 3 = 2 x 2 x 2 = 8 times as much vitality A site with 16 mph normal wind speed will produce about half more power and be more savvy than one with 14 mph normal wind speed (16*16*16)/(14*14*14) = 1.4927 Therefore, it " pay$ " to chase for good twist destinations with better wind speeds

Slide 21

Power in the Wind Velocity is Related to Height Above the Ground

Slide 22

Alpha ( α ) Coefficient α is capacity of the wind speed and its stature over the ground α = log ( V H2/V H1 ) log (H2/H1) α is a marker of the "decency" of a specific site; the more prominent the α , the better the site regarding wind assets, financial matters, ecological advantage, and so forth α can, and varies, yearly, month to month, and day by day α , when all is said in done, is 0.143 (1/7 control law) ( general United States normal) α in the Flint Hills is for the most part more noteworthy than 0.143 (0.16 to 0.24)

Slide 23

Alpha Variation with Time

Wind Energy Economics

Slide 27

Platts "conservatively appraises that producing power from renewable sources can eventually spare customers more than $5/MWh (1/2 ¢ per kW-h) by disposing of fuel cost risk"* *4/8/03 declaration re "Control Price Stability: What's it Worth?" Value of local fuel source (wind) would have an immediate advantage on the Kansas/people group Wind vitality "Fuel" is swelling confirmation; in this way impenetrable to fuel value climbs Wind Insures Against Fuel Price Risk

Slide 28

Cost of wind vitality is unequivocally influenced by normal wind speed and size of wind homestead The taller the turbine tower and the bigger the zone cleared by the sharp edges, the all the more intense and gainful (practical) the turbine Comparative Cost of Wind Energy

Slide 29

Wind Power Costs Wind Speed Assuming a similar size venture (add up to MW introduced), the better the wind asset, the lower the cost; catch more vitality for a similar capital/introduced/upkeep cost

Slide 30

Wind Power Costs Project Size Assuming a similar wind speed, a bigger wind ranch is more temperate; economy-of-scale related with wind cultivate establishment

Slide 31

Environmental and Other Factors Associated With Energy Sources

Slide 32

Benefits of Wind Power Environmental Electric Utilities are a Primary Source of Our Nation's Air Pollutants, including: Sulfur Dioxide Carbon Dioxide Nitrous Oxides Particulate Matter Toxic Heavy Metals Source: Northwest Foundation, 12/97 0% 20% 40% 60% 80%

Slide 33

Turbine unwavering quality Aesthetics Noise Bird crashes Shadow glimmer Ice Safety Property estimations Siting Issues

Slide 34

Aesthetics Modern turbines utilize tubular towers Turbines at many locales must be isolated every which way to stay away from turbulence Larger size = more extensive dividing Modern turbines turn about once at regular intervals

Slide 35

Siting of Wind Turbines Energy substance of twist fluctuates with the 3D shape of the wind speed. (Twice as much wind yields eight circumstances as much vitality.) Roughness of the territory influences neighborhood wind speed. Rough landscape may make turbulence which may diminish vitality creation and increment wear and tear on turbines.

Slide 36

Land Use & Wind Energy In a commonplace wind stop, turbines and get to streets involve under 1% of the region. The staying 99% of the land can be utilized for cultivating or touching, not surprisingly.

Slide 37

Noise & Wind Energy Wind cultivate at 750-1000 feet is no noisier than a kitchen icebox or a respectably calm room. Foundation clamor for the most part veils any turbine commotion totally, particularly at twist rates of 8+ meters/second. Examination of clamor levels: Rural evening time backgrou
