Electrical production in the United States is typically produced in a power plant but can also be
supplemented by renewable sources of energy as well.
Describe why pairing solar energy with energy from natural gas makes this renewable source a
more viable method of electrical production for more United States consumers.

Renewable sources of energy are increasingly contributing to the total energy supply in Canada.
Currently, hydroelectric power is Canada’s largest renewable energy source. Hydroelectric facilities can
have major impacts on aquatic ecosystems.
Propose a solution, other than switching to a different renewable energy source, that can reduce
the impacts of hydroelectric dams on migratory species.
