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.

Discuss the seven characteristics of useful information.

Discuss the seven characteristics of useful information. Answer: The seven characteristics of useful information are: relevant, reliable, complete, timely, understandable, verifiable and accessible. These characteristics are qualities that information should possess to be useful in a business environment. Briefly stated, in order for information to be useful it must be: 1) relevant, meaning that it reduces uncertainty and adds to the decision-making process; 2) reliable information is information that is free from error, and is accurate in its nature; 3) complete information is information that does not omit any important data, facts, or aspects about events or activities; 4) information is timely when it is fully available to enable the decision-making process to proceed; 5) understandable information must be both in an intelligible and useful format; 6) information is considered verifiable if two people, acting independently of each other, produce the same inform

Why have accounting software packages been designed with separate transaction modules?

Why have accounting software packages been designed with separate transaction modules? Answer: : Since every organization does not necessarily use all of the transaction cycles in its operations, it is to the advantage of the organization to be able to "pick and choose" from among various software modules that track and record different transaction cycles. For example, a law firm would have no need to implement a production cycle module. Also, the nature of a transaction cycle varies across the broad spectrum of business organizations. Again, a law firm would have a revenue cycle, but it would not involve the purchase, receipt, and payment for products or merchandise; likewise a retail store chain may not sell any consulting services to its customers.

A laboratory assistant prepared solution of 0.8 M, 0.6 M, 0.4 M, and 0.2 M sucrose, but forgot to label them. After realizing the error, the assistant randomly labeled the flasks containing these four unknown solutions as flask A, flask B, flask C, and flask D.

A laboratory assistant prepared solution of 0.8 M, 0.6 M, 0.4 M, and 0.2 M sucrose, but forgot to label them. After realizing the error, the assistant randomly labeled the flasks containing these four unknown solutions as flask A, flask B, flask C, and flask D. Design an experiment, based on the principles of diffusion and osmosis, that the assistant could use to determine which of the flasks contains each of the four unknown solutions. Include in your answer (a) a description of how you would set up and perform the experiment: (b) the results you would expect from your experiments: and (c) an explanation of those results based on the principles involved. (Be sure to clearly state the principles addressed in your discussion.)
