Energy Resources - Chapter Summary and Learning Objectives
Whether we realize it or not, we all use a variety of energy resources throughout the day. In this chapter, our experienced instructors explain the kinds of energy, how they are used, and how they're found in nature. You'll learn the most important concepts associated with energy resources, including vocabulary terms. At the end of this chapter you should be able to:
- Explain what energy is and why it matters
- Give examples from nature of chemical, thermal and radiant energy
- Describe various forms of renewable and non-renewable energy
- Explain the difference between renewable and non-renewable energy
- Define the first and second laws of thermodynamics

1. What is Energy? - Definition and Significance in Nature
This lesson describes the nature of energy and how it is transferred from one source into another. Additionally, it will describe the significance of energy in natural systems.
2. Renewable & Non-Renewable Resources: Definition & Differences
We use a variety of Earth's resources, but not all of them will be around forever. This lesson explains the difference between resources that can be regenerated for our use and those that are gone after they are used once.
3. What Are Fossil Fuels? - Definition, Advantages & Disadvantages
Fossil fuels are sources of energy that have developed within the earth over millions of years. Because fossil fuels - oil, natural gas, and coal - take so long to form, they are considered nonrenewable. Learn more about these fuels, including the pros and cons of using them.
4. What is Chemical Energy? - Definition & Examples
This lesson describes chemical energy as a type of potential energy stored in chemicals, such as sugar and gasoline. The lesson discusses how energy is transferred from solar energy to chemical energy by plants and how gasoline is a source of chemical energy used to move cars.
5. What is Radiant Energy? - Definition & Examples
This lesson defines and describes radiant energy in its different forms. The different types of electromagnetic waves created by radiant energy are identified and described as well. This includes X-rays, microwaves, and radio waves, to mention a few.
6. What is Thermal Energy? - Definition & Examples
This lesson defines and identifies examples of thermal energy everywhere from your kitchen to the Earth's core. We'll discuss geothermal energy, a renewable energy source, as well.
7. Wind as a Renewable Energy Resource: Advantages & Disadvantages
Wind power is a renewable energy resource, but there are both pros and cons to this type of energy. In this video lesson, you will learn about wind power as well as some of the benefits and drawbacks of using it as a global energy source.
8. What is Nuclear Energy? - Definition & Examples
You've probably heard of nuclear energy. But what is it? And what is the difference between fusion and fission? This lesson will answer your questions about this exciting form of energy that involves atoms and their nuclei.
9. Hydroelectric Energy: Definition, Uses, Advantages & Disadvantages
In this video lesson you will understand how water can be used to generate electrical energy. You will also identify some benefits and drawbacks of using this type of renewable resource for energy production.
10. Tidal Energy: Advantages and Disadvantages
The tides move a massive amount of water, and the energy from this moving water, known as tidal energy, can be captured and converted into electricity. Learn how tidal energy works and the advantages and disadvantages of this energy source.
