Engineers Are Action Oriented Action Means Change and

Different Segments of Society Have Different Goals and Values

Good Intentions Can Produce Unexpected and Unwanted Results

Only Six Percent of the Public Are Scientifically Literate

Actions Have Unforeseen Scientific, Political, and Social Consequences

Unforeseen Consequences Classic Example #1

Original Problem: Soil Erosion

Solution: Introduce Kudzu from Japan

Unintended Consequence: Overrun with VinesKilling of Other VegetationPower Lines Shorting OutEtc. Southeastern USA Kudzu

Solution: Industrialization

Unintended Consequence: Air PollutionSweat ShopsUrban Problems Santiago Chile Smog

When Should the Public be Informed?

Inform the public whenever society could be affected by the proposed project except in cases of simple consumer options or national security authorized by the legally empowered governmental agency.

Procedures to Limit Unintended Consequences and Gain Public Consent

Study similar problems and previous solutions to determine their societal impact

Identify technological trends associated with the proposed solution

Project possible societal impacts of these trends to limit unintended consequences

Research all laws and regulations that may exist concerning a proposed solution

Determine the appropriate ways to inform society and achieve an informed consensus

Question to BHP&L:Would you be able to provide a range, or approximate value, of wind power or the approximate market value of interruptible power?  I am assuming they are one in the same.

We do not need precise values but something in the ballpark.  I am suggesting that interruptible power might be 0.5 to 1.0 cents per KW-HR (I believe these are usually quoted as MW-Hr).

Could you tell me if there are any, or expected to be, any governmentally mandated values for wind power returned to commercial lines by wind farms?

The above info would be most useful an adequately meet our parochial needs.  However, if you have a publically disseminated estimate of cap-and-trade impacts, that would be most interesting to my students.

Reply: “You are tackling a complex issue.”  The value of wind power and the value of interruptible power are not the same.  Wind power has two components, the energy produced and “green” attributes.  Typically if a customer is purchasing wind energy they are purchasing the “green” attributes.  Because of the energy component,   any wind generation produced on a utility’s system must be regulated so that when the wind doesn’t blow the utility can still keep the lights on.  This is done by contracting with a 3rd party or installing quick start generation to regulate the wind turbine output.  So from a cost benefit analysis you will want to draw a connection between wind energy (with additional generation for regulation) vs. just adding generation to serve load.

Andy Butcher is the manager of our marketing department and he said he would be willing to discuss wind as it related to the overall system.  It is important to understand how wind integrates to the overall system before you start comparing prices in a cost benefit analysis.

To answer your question on government mandate pricing on wind…..I am unaware of any mandates.  Some states have mandates on the amount of renewable energy in the state which can have an effect on pricing but currently I am not aware of an direct pricing mandates.  Chicago Climate exchange would be a potential source of info with respect to carbon cap and trade.  It is my understanding that the rules of their system are set up to model what many feel a government mandate cap and trade system will look like.

Engineering’s Impact on Society

Seek Input

Provide Accurate Pertinent Technical Information

Embrace the Regulatory Environment as an Valuable Operating Template

Never Violate the Public Good

Use Secrecy only for intellectual rights, simple market-related activities, or government authorized activity
