Renewable & Non-Renewable Energy – JSS1 Basic Science Lesson Note (Second Term)

Renewable energy comes from resources that can be replaced as they are used up, such as the sun, wind, water, biomass, tides and biofuel. Non-renewable energy comes from resources that cannot be replaced as they are used up, such as nuclear materials, petroleum, natural gas, coal and other fossil fuels.

Behavioural objectives

By the end of the lesson, students should be able to:

• explain renewable and non-renewable energy;
• list examples of renewable sources of energy;
• list examples of non-renewable sources of energy;
• state the uses of energy;
• name the problems caused by the misuse of energy resources.

What are renewable and non-renewable energy?

Renewable energy refers to energy resources that can be replaced as they are used up.

Non-renewable energy refers to energy resources that cannot be replenished as they are used up.
