Hydropower Webquest

Introduction

As you learned in my presentation, hydropower is derived from the movement of water, especially in rivers.  Most hydropower is produced at dams, where a reservoir is created and flow through the dam can be easily captured.  In some cases, water flowing down natural waterfalls is captured and converted into electricity.

For centuries, people took advantage of hydropower to propel machines like mills for grinding grains or saws for cutting lumber.  The use of hydropower to create electricity was quickly realized at the end of the 19th Century.  The middle of the 20th Century saw great growth in hydropower, especially in the United States.  The last few decades has seen relatively little increase in hydropower development in the U.S., mainly because all of the major rivers have already been harnessed.  Instead, hydropower development has occurred mostly overseas, particularly in China.

Many people believe that hydropower still holds great promise as a viable alternative to coal and nuclear fission for generating electricity.

The purpose of this webquest is to enable teams of students to learn more about hydropower, and determine its potential to continue 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 hydropower can provide a significant proportion of electrical demand in the future?
  • Does everybody agree with that evidence?  If not, explain.
  • We know that hydropower, especially for electrical generation is localized. 
    • Can production be enhanced in those areas in which it is already developed?
    • Can production be developed in areas where it is now minimally developed?
  • What potential does novel application of hydropower (e.g., capturing tidal flows) hold?
  • What environmental problems does hydropower pose?
  • What social / political problems?
  • Do any laws or regulations prevent the deployment of new hydropower?
  • Is hydropower truly sustainable?
Process

Student teams will conduct a webquest using the following websites:
On 19 November, 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 a rubric under development.  The grade will reflect both an individual and a team performance.
