Introduction to Science - Energy Portfolio exercise
(Please hand in at the start of class next week)
1. The most economical means of solar heating is an Active or Passive system?
2. What is the difference between active and passive solar power? Give an example of both
3. Briefly describe how a photovoltaic cell works.
4. Look at the diagram below which shows global solar radiation input
a. Describe (with values) the effect of latitude on the amount of solar energy available in December in the northern and southern hemispheres
b. List two factors other than latitude which may reduce the usefulness or availability of solar power
5. List three advantages of using solar power
5. Look at the Guardian Energy webpages on https://www.theguardian.com/environment/energy
