Solar Power Webquest

Introduction

As you learned in my presentation, solar power is derived from the flux of photons from the sun.  It is the source of most biological productivity thanks to photosynthesis.  Solar energy can be used directly to provide heat and light, such as through celestory windows or solar tubes.  Or it can be trapped by solar panels and converted into electricity via a photovoltaic or thermal process.

The use of solar power has significantly increased in the past decade, due largely to declines in the cost of technologies to capture the sun's energy and convert it into a form that people can use.  Many people believe that solar power has great potential to provide far more of our heating, lighting, electricity, and even transportation needs than it does now.  The most ardent advocates even believe that solar power should be THE dominant form of energy in the decades to come.  Others believe that solar power has limited potential, especially in areas that do not receive significant sunlight.  They contend that the costs associated with solar energy are large compared to the benefits.

The purpose of this webquest is to enable teams of students to learn more about solar, and determine its potential to serve as a significant source of renewable 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 solar can provide a significant proportion of energy demand in the future?
  • Does everybody agree with that evidence?  If not, explain.
  • During my presentation, I suggested that solar energy has been best developed in areas having high sunlight and low cloud cover such as tropical and desert areas. 
    • Can energy production from solar energy be enhanced in those areas?
    • Can energy production from solar energy be developed in less sunny areas (such as northern Europe, or northeastern and northwestern U.S.?
  • What environmental problems does solar energy pose?  Are those problems real or exaggerated?
  • What social / political problems?
  • Do any laws or regulations prevent the deployment of solar energy in the US? Other industrialized countries?  Non industrialized countries?
Process

Student teams assigned to this topic 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 the following rubric.  The grade will reflect both an individual and a team performance.
