Shale Gas Webquest

Introduction

The seventh alternative energy source considered in this course is natural gas derived from shale.  As you learned in Dr. Halsor's presentation on 23 November, shale rock (such as that found in the local Marcellus formation) contains significant amounts of trapped natural gas material.  Once extracted, the gas can be shipped to various parts of the country to power electrical plants, heat homes, or be used by various industries.

Many people believe that the gas in shale rock holds great promise as a viable alternative to "dirtier" fuels like coal, it is more abundant than oil, and does not have the long-term waste problems like nuclear fission.  Others are concerned with the environmental risks, especially to groundwater resources and surface waterways like streams and rivers.  Moreover, shale gas is a fossil fuel, and burning it will add greenhouse gasses to our atmosphere.


The purpose of this webquest is to enable teams of students to learn more about shale gas, and determine its potential to serve as a significant source of alternative energy in the future.


Task

The teams assigned to this webquest are to review the websites listed below.  Students in those teams are to answer the following questions:
  • What evidence supports the idea that products of shale gas can provide a significant proportion of energy demand in the future?
  • Does everybody agree with that evidence?  If not, explain.
  • Dr. Halsor's presentation suggested that shale gas is geographically best developed in certain locations based on geology.
    • What are the reserves of shale gas worldwide?  In the US?  In Pennsylvania?
    • Approximately how much of the shale gas has been tapped at present?
    • Are some reserves too difficult to get to?
  • What environmental problems does shale gas extraction pose?  What benefits are there?
  • What social / political issues relate to shale gas development?  Specifically, what are the economic factors involved in shale gas development, both for companies and property owners?
  • Do any laws or regulations prevent the deployment of shale gas development?  How is shale gas production taxed?
Process

On 4 December, student teams will conduct a webquest using the following websites:
Of course, you may work outside of class as a team to further research the topic, generate a synthesis, and formulate a presentation.

On 9 December, student teams assigned this topic will each give a 20 minute Powerpoint-based presentation in which they will answer the questions.

Evaluation

Students will be evaluated using the following rubric.  The grade will reflect both an individual and a team performance.
