Grade 11 Energy Resource Comparison Activity

Revision activities / Physics study practice

Learning focus: Environmental and Space Physics. This original Grade 11 Physics exercise gives you a task, a suggested response and a follow-up challenge. It is classroom practice, not an official assessment paper.

Understand the idea

Energy choices involve availability, cost, reliability and environmental effects across the system. Renewable does not mean impact-free.

Try the activity

Compare solar and geothermal electricity for a Kenyan community. Give one strength and one limitation for each.

Attempt your response before opening the guidance. Show the steps, textual evidence or reasons that support your answer; a final answer alone may hide a misunderstanding.

Show suggested answer and reasoning

Solar is modular and uses sunlight, but output varies with daylight and weather unless supported by storage or other supply. Geothermal can provide steadier output at suitable sites, but requires appropriate geology and substantial development.

Follow-up challenge

Build a comparison table and distinguish installed capacity from actual energy delivered. Avoid inventing local prices or claiming that one source suits every location.

Review your work

  • Did you answer the question actually asked?
  • Can you explain the method or evidence in your own words?
  • What would you change if one condition in the task changed?

Use the suggested response to identify one correction, then attempt the task again without copying it. For an open-ended question, other well-supported answers may be reasonable. Ask your teacher to check interpretations or language forms where needed.
