Points to Consider
- If it takes energy to get energy, then what are the best choices for types of energy?
- Put each of these actions in order from most important to least: choosing a sustainable
form of energy, increasing energy efficiency, conserving energy use. Explain the order
you chose. - Could everyone in the world use as much energy as a person in the United States does
each day? Why or why not?
