Question

part c
in a separate location, take notes from the sources you’ve identified. the notes will provide details for your
presentation. while taking notes, you may want to use these reading strategies . write down one or two
pieces of information per topic that you intend to use in your presentation. use these sources if you find
them helpful:
combustion of fuels
how much carbon dioxide is produced?
acid rain
biomass
biodiesel fuel
sources of energy
table with columns topic and main points, rows: chemical reactions of fossil fuels, difference between biomass and fossil fuels, comparing biomass with other renewable energy sources, making energy choices locally

Answer:

To complete the note - taking for the presentation, we analyze each topic using the provided sources:

Topic: Chemical reactions of fossil fuels

• Source: Combustion of Fuels
• Main Point 1: Fossil fuels (such as coal, oil, and natural gas) undergo combustion reactions. In the presence of oxygen, they react to produce carbon dioxide ($\ce{CO_2}$), water ($\ce{H_2O}$), and release a large amount of energy. For example, the combustion of methane ($\ce{CH_4 + 2O_2\xlongequal{combustion} CO_2 + 2H_2O}$).
• Main Point 2: The combustion process of fossil fuels is an exothermic reaction, which means it releases heat. This heat energy is harnessed for various purposes like electricity generation and transportation.

Topic: Difference between biomass and fossil fuels

• Source: Biomass, Combustion of Fuels
• Main Point 1: Biomass is derived from recently living organisms (like plants, wood, and agricultural waste), while fossil fuels are formed from the remains of organisms that lived millions of years ago.
• Main Point 2: Biomass is a renewable energy source as it can be replenished in a relatively short time (through plant growth, for example), but fossil fuels are non - renewable as their formation takes an extremely long geological time scale.

Topic: Comparing biomass with other renewable energy sources

• Source: Biomass, Sources of Energy
• Main Point 1: Compared to solar energy, biomass energy can be used continuously (not just during the day or when the sun is shining) and can be stored more easily. However, solar energy production does not produce greenhouse gases during operation, while biomass combustion may still produce some $\ce{CO_2}$ (although it is considered carbon - neutral in the long run as plants absorb $\ce{CO_2}$ during growth).
• Main Point 2: In comparison to wind energy, biomass energy production is less dependent on weather conditions (like wind speed and direction). But wind energy generation has a lower impact on land use compared to biomass production which may require large areas of land for growing biomass feedstocks.

Topic: Making energy choices locally

• Source: Sources of Energy, Biodiesel Fuel
• Main Point 1: Local energy choices can consider the availability of resources. For example, if there is a large amount of agricultural waste in a local area, biomass energy production (such as converting the waste to biofuels) can be a viable option.
• Main Point 2: Using local energy sources like biodiesel (produced from local vegetable oils or animal fats) can reduce the dependence on imported fossil fuels, which can have economic and environmental benefits (such as reducing transportation - related emissions from fuel import).

If we were to fill in the table:

Topic	Main Points
Difference between biomass and fossil fuels	1. Biomass from recent organisms; fossil fuels from ancient organisms. 2. Biomass is renewable, fossil fuels non - renewable.
Comparing biomass with other renewable energy sources	1. Biomass can be used continuously and stored easily compared to solar; solar has no GHG during operation, biomass has some (carbon - neutral long - term). 2. Biomass less weather - dependent than wind; wind has less land - use impact.
Making energy choices locally	1. Use local resources (e.g., agricultural waste for biomass). 2. Local biofuels (e.g., biodiesel) reduce fossil fuel import dependence.
