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.

Summarize effective communication strategies in organizational hierarchies, and review the role and relevance of the organizational grapevine Some companies try to encourage communication through workspace design, as well as through Web-based communication channels. some executives also meet directly with employees, such as through management by walking around (MBWA) and town hall meetings, to facilitate communication across the organization. In any organization, employees rely on the grapevine, particularly during times of uncertainty. The grapevine is an unstructured and informal network founded on social relationships rather than organizational charts or job descriptions. Although early research identified several unique features of the grapevine, some of these features may be changing as the Internet plays an increasing role in grapevine communication.
