Learning Objectives

After these lessons, students should be able to:

• Describe what energy is as well as different sources and uses of energy.
• Define renewable and non-renewable energy sources and provide examples of common types
of renewable and non-renewable resources.
• Understand and explain general ways to save energy at a personal, community and global
level.
• Understand and explain, in general terms, how RES systems work and describe some general
characteristics of RES sources and why they are important.
• Understand the benefits and disadvantages to using renewable and non-renewable sources.

What is energy?

The simplest definition of energy is ‘the ability to do work or cause change’.
Work is the application of a force through a distance. (Ask students for examples, such as moving a box
across the room, sweeping, etc.)

• Force can put matter into motion or stop it if it is already moving.
• Motion is a change in position of an object with time.

To do work, energy is needed during our daily activities!!! Houses, industries, transportation, energy
is used everywhere!
From where does energy come?

• Natural energy sources: food, water, plants, trees, gravity, sun, fossil fuels, uranium,
plutonium;
• Ways that humans have harnessed or converted natural energy sources: hydroelectric dams,
coal/oil power plants, nuclear power plants, wind turbines, solar panels, etc.

What are different types of energy? (See the Glossary section.)

• Kinetic energy: electrical, light, thermal, solar, sound, wind, hydro
• Potential energy: chemical, mechanical, nuclear, gravitational
