The Texas state government decided to offer subsidies in 2020 for energy production by solar
power in the form of a consumer tax credit. Explain how these government subsidies would
affect the energy production by coal by 2030 in Texas.
Studies indicate that between the present and 2050, substantial growth in population and energy consumption will occur both in less developed countries (LDCs) like India and China and in more developed countries (MDCs) like the United States and Japan. The table below displays these projections.
Calculate the percent increase in total energy consumption by LDCs between the present and 2050

Researchers state that the 2011 Tohoku earthquake and tsunami in Japan had a positive impact on
nuclear power generation in Japan after the event. Make a claim that supports or refutes this
statement based on evidence in the graph.
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.
