Introduction to Energy Resources
Study Tip
Just as the letter “F” comes before “H” in the alphabet, Fuel needs to be burned in order for Heat to be released.
Energy
- Energy is the ability to do work or cause change.
- All forms of energy apply to the law of conservation of energy, which states that energy is neither created nor destroyed.
- This means that the amount of energy is always the same, even though its form may change.
- All organisms receive their energy from the sun either indirectly or directly, depending on whether they are producers or consumers.
Types of Energy
- Energy exists in a variety of types, depending on the type of activity an organism does.
- Chemical energy is the energy stored in the chemical bonds in molecules.
- Kinetic energy is the energy that is stored through motion.
- Potential energy is stored energy that has the capability to do work.
- Energy has two main forms:
- A fuel is a material that releases energy as it chemically changes.
- Heat is the energy from the movement from atoms and molecules that can be transferred.

Study Tip
The same way a person may cast a shadow over another person when they stand under the sun, planets or celestial bodies that have aligned themselves cast shadows over one another as well.
Burning fuels can release energy through heat.
Concept Check
- Where does all the energy on Earth come from?
- What are the three main types of energy?
- How is fuel and heat related to the creation of energy?
