    1. I really would like to know the answer to #5. Another ? ...are any of the wind turbine parts made in Kansas?

      Delete
    2. All good questions!! I had some of the same thoughts. I wish I knew some of the answers. I also would like to know how you become a wind farm land owner. I hear they get paid very well!!

    3. The 'environmental impact' is one of my questions, too. It seems to be pretty significant during the initial construction process...but does the environment recuperate in the long-term?

      Delete
    4. I found question 7 interesting because some people in Hutchinson are being asked to take their private turbines down.

      Delete
    5. I believe that LaCrosse does not allow turbines in city limits. I assume other cities have the same rules.

      Delete
  3. My questions regarding wind energy are:
    1) Is wind energy economically feasible on a persona/individual level?
    2) How does wind energy get stored?
    3) What is 'the grid'?
    4) How does energy get on 'the grid'?
    5) How far geographically does it travel?
    6) Are wind turbines in Kansas producing energy for NYC -other high populated areas?
    7) Does this help or hurt our energy costs locally?
    8) Who owns the wind farms?
    9) Is it noisy close to them?
    10) Is the air cooler around them when they are going?

    1. Also, all good questions!! I also would like to know what "the grid" is. I know it is where they read how much power is produced (or at least I think I know). Hopefully the workshop in July will answer most of these questions.

    2. The wind farm in Gray County has been operational for many years now, but one of the complaints I heard was about the noise created by the turbines. It will be interesting to hear if these complaints are well founded and common throughout the state.

      Delete
  4. Cyn, I will be anxious to hear if anyone has an answer to your ? #9.

    1. When all is considered. when the 'whole picture' is looked at, are they truely good for our earth....would solar power be even better?

      Delete
    2. I wonder about this, too? Is wind one of those 'environmentally friendly' things like ethanol...where when you look at the cost of growing the crops (fossil fuel inputs, water, etc.), plus the pollution output from the end product that the benefit to the overall environment really isn't that much?

      Delete
  6. Good questions! What is the life expectancy of a wind farm and how productive are they vs fossil fuels? I've wondered the same things.

    ReplyDelete
  7. I think your question about longevity of that massive structure is a good one. Are we going to have a field that looks like the skeletal remains of wind turbines in our countryside??

  8. Re: Assignment 2, third bullet (constructing an initial - preresearch-ESS analysis:
    E = There is considerable debate on whether building a Wind Farm is economically feasible and environmentally good for Kansas.
    E>A : The big wind turbine blades will create currents and turbulence in the immediate atmosphere.
    E>L: The ground will support the massive structure without modification or reshaping the land.
    E>H: The location of the turbine will be away from any close open waterways.
    E>B: The local wildlife and vegetation will be minimally affected.

    ReplyDelete
  9. Continuing on Assignment 2, third bullet:
    E>A>B: The creation of currents and turbulence in the immediate area will effect the local wildlife, particullarly the birds and insects populations.
    E>A>H>B: The increased wind currents will increase evaporation thus limiting the supply for all area wildlife and fauna.

  10. Regarding question 2 third bullet constructing an initial (pre-research) Earth Systems Science Analysis

    E = I am considering the building of Wind Farms in rural Kansas. I am wanting to determine if Wind Farms would have a positive or negative effort on our environmental area.

    E>A A wind turbine is a huge manmade structure with long arms that is turned by the wind.

    E>H The setting of wind turbines are typically located in non-urban settings. Within these settings one would find possibly ponds, streams, natural springs, and rivers.

    E>L A wind turbine is a very large structure weighing several thousand pounds. There is numerous wind turbines located in close proximity to one another.

    E>B The wind turbines on a Wind Farm are located in a rural setting like a pasture or grassland . There would typical be many native animals that would be living at these locations.

    E>H>B Less water due to increased evaporation in and around wind turbines may have an effect on the population of wildlife.

    E>A>B Wind shifts and turbulence might be created or made greater by turning wind turbines.

  11. Initial ESS analysis:
    Event - Do the benefits of building a windfarm overcome the negative effects on our environment?

    E>L
    Putting in a wind farm will initially cause some disturbance to the soil in the building of the farm.

    E>H
    Using wind energy over fossil fuels will create less chemicals to contaminate our rivers, lakes, streams, and ponds.

    E>A
    Using wind energy over fossil fuels will create less pollutants to contaminate our atmosphere.

    E>B
    Building a windfarm will create habitat destruction and possibly dissrupt migratory flight patterns.

    E>B
    Building a windfarm will create noise pollution.

    E>B
    Building a windfarm will cause disturbance to our native grasses.

    E>B>A
    Building windfarms will reduce the need for fossil fuels, which will reduce the carbon dioxide released into our atmosphere.

    E>B>L
    Building windfarms will reduce the need for fossil fuels which will reduce th acuse of erosion from mining or drilling ores.

  12. Questions I have:
    1. Are wind turbines for individuals or small business owners cost effective?
    2. What has been the effect of wind farms on the Kansas economy, specifically jobs, energy production, costs,etc.
    3. Who is making money off of wind energy?
    4. Is the government supplementing the cost? If so, is this being passed on to the consumer?
    5. What are energy companies paying for the electricity from wind farms versus other providers?
    6. Are there fewer environmental effects to wind energy production than other forms?
    7. Are Americans willing to pay more for energy that is produced with fewer environmental effects?

    1. Carlotta: I wonder about the cost effectiveness for individuals as well. I've always had this dream of living 'off the grid' and would love to be able to convince my skeptical hubby that it is feasible:)

    2. My husband has wind and solar at his business. Both of these pretty much pay for his electric bill every month. Sometime the meter actually runs backwards!!

      Delete
    3. Number 6,I feel, is one of the biggest reasons for making this all happen? I think we are going to be encouraged by our findings.

      Delete
    4. #6 - Yes, the government does supplement the cost. There was an energy kickback passed in 2009 I believe that helped individuals put up turbines. Our neighbor explained it as being able to write off 30% of the initial costs on his taxes.

  13. Initial Questions About Wind Energy:
    1. What is the cost (monetary) to erect a wind turbine?
    2. How much electricity can said turbine produce?
    3.What is the projected time frame for the turbine to pay for itself?
    4. Where does energy produced by KS wind farms get utilized?
    5.What is the environmental impact of wind turbine manufacture/construction?
    6.What is the long term environmental impact of the turbines on the prairie ecosystem (ie. Wildlife disturbance, erosion, etc.)?
    7.What benefit/incentive is there for KS residence to give up their land for a wind farm?
    8.What impact does living in the wind farm shadow have on KS residents?

    1. #3 - I would like to know this as well. You always see at least one not turning/broken down when you drive by them either on I-70 or heading to Dodge City.

      #7 - regarding the idea of someone else putting up a wind farm on my land: I would much rather put something up by my own volition than letting a strange company do it. Land lease companies can be kind of sketchy and the contracts they supply really need to be looked over by an attorney.

  14. Initial ESSEA Analysis (Pre-Research)
    Focus Question: Do the environmental impacts of construction and operation of a KS wind farm outweigh the benefits of the clean energy production?

    Event: Wind farm construction and operation on the prairie

    E> B (Human actions)> L Extraction of construction materials from the ground (metals, concrete components, etc.)

    E> B (Human actions)> A Air pollution from the from the creation/refinement of raw materials into turbine components.

    E> B (Human actions) >A Air pollution (exhaust) from the transport of component parts to the wind farm site.

    E> L> H Destruction of roadways and prairie soil by heavy equipment. Eroded particulates are carried by rain events to nearby waterways.

    E> B Displacement/destruction of native prairie vegetation and wildlife species during construction process.

    E> B Effects from continued turbine operation on migratory bird patterns, plant growth, etc.

    A> E> B (Humans) Large amount of wind in KS hopefully allows the production of large amounts of electricity. Electricity makes life more ‘comfortable’ for humans as a species.

    E> A Atmospheric levels of CO2 and other greenhouse gases decrease because of reduction of fossil fuel related energy sources.

  15. After reading the information I found it interesting that we always focus on the negative first. So I tried to push myself to find positive relationships.
    Here is my ESS analysis:
    Event: Building a Wind Farm
    E>H Energy production with wind reduces the need to drill for oil and natural gas, reducing the amount of water pumped from the Ogallala Aquifer.

    E>L Energy production with wind reduces the damage to the soil from drilling and fracking.

    E>B Wind Farms take up land currently used for farming, decreasing the amount a food available for an expanding population.

    E>A Energy production with wind reduces the need for coal burning energy plants that increase air pollution.

    1. Hadn't thought about the need to drill less and the positive impact that would have on the water supply. Interesting point!!

      Delete
  16. Good point, Carlotta! I think it is human nature to see the negative so we can avoid the pitfalls. However, once the pitfalls are avoided, the positive aspects become important.

  17. My questions about wind energy are:

    1. How does the cost to produce wind energy compare to the cost of other energy sources?

    2. How much energy is produced by one turbine? How many turbines does it take to power one city?

    3. How close together can wind turbines be placed?

    4. Do they change the local wind patterns or affect wildlife?

    5. What happens when the current turbines become out of date? Will they be removed and at what cost?

    6. What is the cost to install and maintain the turbines? How does this compare to the cost to maintain other power plants?

    ReplyDelete
  18. I also wonder about your second and third questions. I know that technology is always changing and I really wonder if they will come up with a better design of turbine and then what will they do with the old ones? It takes a lot of resources to truck them to the site. I can't imagine them all being trucked away. I see turbines shut down all the time when traveling past the wind farm on I-70. I suppose this is for maintenance but is it also because the terminal needs to be replaced? How much longer will those terminals be functional?

    ReplyDelete
  19. Focus question: What is the feasibility of erecting turbines on our farm for personal usage (small business) or reselling to grid?
    E>L Acreage for consideration is roughly 1500 acres in various tracts.
    E>L Rocks and soil should suffer no more trauma than no-till farming already gives it, possibly less.
    E>L Current land is not suitable for drilling oil wells and transmission lines for natural gas are too far away to be feasible for drilling/delivery purposes, which makes it a candidate for another source of earned income.
    E>L>B>H Fields would be disrupted initially, then farming/grazing could co-exist with the turbines.
    E>H Ponds and streams would remain as is without any disturbance.
    E>B Noise pollution is minimal compared to normal, daily occurrences by others in the area.
    E>B Erection of turbines would provide jobs.
    E>B Animal loss due to flying into turbines or loss of habitat would be no more significant than hitting an animal with a car or natural selection of trees, animals, etc.
    E>B Wind energy cannot be stored therefore turbines would produce the most energy in the summer months when the wind is blowing.
    E>A Wind energy is a renewable resource and would have no negative impact on air quality.
    E>A>B Turbines must take into account the rolling hills (or lack of) making them quite tall.

  20. ESS Analysis- Building a Wind-farm
    How could a wind farm affect each sphere?
    E>A- Wind turbines stick up high into the air. They have large spinning blades. There have been studies done to see the effect of them on birds and this is frequently a concern of people.
    Do wind farms change air patterns? When driving on the highway on a motor cycle I notice that the other vehicles on the road seem to change the wind patterns there. I assume that these giant turbines might do the same.
    Are there a lot of fossil fuel emissions associated with constructing and transporting wind turbines? Are there any measures being taken to decrease these?
    Does the energy produced by a wind turbine actually emit less greenhouse gas than a traditional power plant? I would assume so.
    How tall are wind turbines?
    E>B-Animals and plants live in the area where turbines will be installed. We do not want to install something that will have a negative effect on wildlife.
    Do wind farms affect migratory birds? Do birds die when they fly into wind turbines?
    Does the noise from the turbine affect grazing animals in the area? How about the construction of wind farms…does it destroy habitat or disrupt mating?
    How does the disruption to plant and animal life compare to the disruption due to drilling for fossil fuels?
    E>H-Depleting and contaminating ground water are concerns when any new construction is done. It will be important to take this into consideration if building a wind farm. Trucks driving in and out of fields leave ruts these ruts could collect ground water. The truck traffic in and out of fields could also kill plants which might keep water from being held in the soil.
    What role does water play in the construction, transport, installation, and operation of a wind farm?
    I would assume that the hydrosphere is the least affected.
    Are weather patterns changed by wind turbines?
    E>G- Kansas has a lot of oil and gas exploration. New methods for drilling for fossil fuels involve drilling horizontally. I believe it would be important to study how this has altered the rock underneath a potential wind energy site.
    If mining took place under the area where the turbines are installed will the ground hold them? What if drilling takes place in the area? Will that influence the strength of the footings?

    How could each sphere affect a wind farm?
    A>E- Certain areas are better for placing wind farms than others because of the wind patterns.
    Can wind patterns change? If so what would happen to the wind farm in the event of a change?
    Does the area determine how many turbines are placed?
    B>E- It is unknown how exactly a wind farm will influence wildlife.
    Would environmental studies be done before and after installing turbines? What would happen if significant changes to wildlife were observed?
    Who if anyone would work to correct the problem? Is the problem correctable?
    H>E- Rainfall could slow the building and maintenance of the turbines.
    G>E- If drilling for fossil fuels was happening in the area they might not be able to install wind farms even if the wind zone was correct.
    Who would win out in this situation? Wind or traditional fuels?

    How do the spheres influence each other when it comes to building a wind farm?
    A>G- If the wind patterns are good then turbines will be installed. These put additional pressure on the rocks in the area. Also they will possibly prevent drilling in the area.
    Does putting additional weight on rocks make a difference? Can you drill for fossil fuels near a turbine?
    A>B- Building turbines will have a positive effect on humans by providing more energy. It could have a negative effect on birds or other wildlife.
    Is this the best way for humans to obtain energy?
    How will wildlife be affected? Will they really be affected?
    B>A- Animal rights activists will likely step in and say that turbines should not be built. This will prevent energy from being harvested from the atmosphere.
