Answer:
Common Ideas
Both texts state that conventional energy sources—such as oil and coal—will run out, so people need to start using renewable sources of energy instead.
Both texts list and explain multiple types of renewable energy sources, including wind power, solar energy, geothermal energy, and hydroelectric energy.
Differing Ideas
“Alternative Energy Sources” mentions an additional type of renewable energy called “biomass energy” that comes from plants.
“Alternative Energy Sources” describes how the country of Denmark has been successful at shifting from the use of conventional to alternative sources of energy, while “Energy Sources” does not provide any examples.
Understanding
Because conventional forms of energy will eventually run out, people need to start using multiple forms of renewable energy instead of fossil fuels such as coal and oil.
