What are the advantages and disadvantages of wind power?



Disadvantage of wind power:


  1. The cost of producing electricity from wind must be competitive with other sources to be economically viable -> now it costs less than electricity from natural gas.
  2. Large windmill farms use large areas of land for roads, pads for windmills, and other equipment.
  3. Windmills may degrade an area's scenic resources.


Advantage of wind power: 


  1. Large energy potentially, turbine designs have improved drastically, and cost is competitive with fossil fuels (meaning low cost).
  2. Advantage of areas such as coastal region of the northeastern U.S. and a belt extending from northern Texas through the Rocky Mountain states and the Dakotas, and winds in the Pacific Northwest coastal area.
  3. Serves as an alternative energy source that will help reduce dependence on fossil fuel and help achieve sustainability.
  4. Wind energy is growing at about 30% per year
  5. It is believed that there is enough ewin energy in Texas, South Dakota, and North Dakota to satisfy the electricity needs for the entire U.S.
  6. Advantages for areas such as China where air pollution is a high risk for human health.
  7. Could supply 10% of world's power in the future.
  8. More jobs, major investment opportunity.
  9. Will become cheaper with more efficient wind turbines.

JAD Advantages and Disadvantages : Compared with traditional methods, JAD is more expensive and can be cumbersome if the group is too large relative to the size of the project. Many companies find, however, that JAD allows key users to participate effectively in the requirements modeling process. Read:  What is JAD and how are users involved? What are advantages and disadvantages of JAD? When users participate in the systems development process, they are more likely to feel a sense of ownership in the results, and support for the new system. When properly used, JAD can result in a more accurate statement of system requirements, a better understanding of common goals, and a stronger commitment to the success of the new system.

What is JAD and how are users involved? What are advantages and disadvantages of JAD? Joint application development, is a popular fact finding technique that brings users into the development process as active participants. Users have a vital stake in the information system, and should participate fully in the development process. They are/should be involved at every stage of development. Advantages : Users can participate effectively in the requirements modeling stage. More accurate statement of systems requirements, better understanding of common goals and stronger commitment to success of the new project Disadvantages : More expensive, can be cumbersome if the group is too large for the project.
