Part A The first stage in designing your presentation is to make a list of questions that will enable you to do research. The list is divided by topic. Your presentation should answer these questions: Chemical Reactions of Fossil Fuels What kind of chemical reaction occurs when fossil fuels and biomass are burned? What is produced in addition to energy? What is acid rain? Which fossil fuel causes acid rain? What are the chemical reactions that produce the acid? Difference Between Biomass and Fossil Fuels In terms of environmental impact, what’s the difference between natural gas, coal, and biomass? Consider both carbon dioxide (CO2) emissions and acid rain. What’s the difference between nonrenewable and renewable energy sources? Is biomass a renewable energy source? What’s a new discovery that makes it easier to use biomass as an energy source? Comparing Biomass with Other Renewable Energy Sources What are the pros and cons of several renewable energy sources? Renewable energy sources include biomass, wind power, hydropower, solar power, and geothermal power. Making Recommendations for Energy Choices Which renewable energy sources should be developed in your area, and why? Consider abundance of the energy source, ease of setup in your area, and cost. Review the seven questions. Write a few sentences summarizing what you already know about these topics.
