In class, we explore and discuss the concept of energy demand and energy supply, and how they relate to sustainability. In this assignment, you will examine spatial patterns of global energy consumption using maps and charts. Final energy consumption (composed in large part of oil, gas, coal, etc.), and renewable energy consumption (composed of biomass energy and modem renewable such as wind, solar hydro, etc.) will be compared among countries and related to energy reserves/production, national wealth (GDP), and human population.

This topic is of inherent interest to the studies of energy, global change and sustainability because today the economic transition of countries from less developed to more developed states, is often associated with a transition in the main sources of energy used by a society. This transition of dominant energy sources, in turn, leads to a number of potential environmental consequences, both positive and negative.

Instructions

First, open the Our World in Data website by clicking on the link https://ourworldindata.org.

If you are having a hard time finding the correct charts and maps, please use the following link (https://ourworldindata.org/grapher/primary-energy-cons). The charts for Sections 1 and 2 should be found on this page. However, please follow the directions for Section 3 as these directions are correct.

Using the ‘Articles by Topic’ roll-down the menu and select Energy and Environment, then Energy.

Then click on ‘All our charts on Energy’ so you can scroll up and down a list of energy topics. If you click on one of those energy topics, a CHART, and possibly a MAP, of that topic overtime will appear in a visualization window. You can access one or the other by selecting CHART or MAP at the bottom of the visualization window.

CHART: Depending on the energy topic, you can choose to add or remove one or several countries from the chart. By sliding your mouse over the chart, you can get actual topic values.

MAP: When a topic has a MAP and a CHART representation, the map comes with a time-slide animation feature that you can access by clicking on the arrow on the map left corner. You can also select a specific year by manually moving the time cursor. Finally, you can zoom on different regions of the world by opening the roll-down menu under the ‘World’ box on the upper right corner of the map.

You can download and save charts and maps using the download button located at the bottom-right of the visualization window.

Tip: do not forget to read the topic description provided in the visualization window under the visualization title.

Use the charts and/or maps and lecture content to answer the following questions.

1.On Primary Energy Consumption

Question 1:

oSelect the topic Primary Energy Consumption. The map of the Primary Energy Consumption by country for 2018 will appear. Describe the map and explain what the color variations represent. What countries stand out in this map and why?

oUsing the CHART, how has the Primary Energy Consumption evolved through time for the United States, Europe, China, India and Africa? Just a reminder that you can add and remove countries to and from the chart. Looking at the map of Africa, what limitations do you see with the data?

oWhat do some of the high energy-consuming countries have in common?

Question 2:

oUsing the regional zoom functionality (i.e. the pull down menu on the map) of the Primary Energy Consumption map, list the countries that have a Primary Energy Consumption greater than 25,000 TWh in 2014. You can get the Primary Energy Consumption values by moving your mouse over each listed country.

oThen select the energy topic Energy Use per Capita from the Energy topics list. List the countries that have an Energy Use per Capita greater than 25,000 kWh.

oHow do the primary energy consumption and the energy use per capita maps differ in terms of shifts in the patterns of consumption?

2.Renewable energy consumption

Question 3:

oIn the energy topics list, open the Share of Final Energy Consumption from Renewable Sources topic map. Describe the map and explain the significance of the percentage of renewable energy use in a country’s Primary energy consumption, in term of fossil fuels vs. renewable energy fuels (modern renewable and biomass) use.

oCompare the Share of Final Energy Consumption from Renewable sources map with the Primary Energy Consumption map and briefly describe the major differences between fossil fuels and renewable energy consumption patterns between countries, with particular focus on global trends in their use, and the magnitude of energy gained from each source.

oIn counties that have a share of final energy consumption from renewable sources greater than 50%, what do you think is the dominant source of renewable energy, i.e., biomass or modern renewable energy? Briefly explain your answer.

oBased on what you know about fossil fuel as an energy source and renewable energy (here biomass), describe two possible environmental costs and two benefits of each energy type; i.e. fossil fuels and biomass energy (8 items total).

Question 4:

oWhich is higher in your country and its neighbors, fossil fuel or renewable per capita energy consumption? Is this what you would have expected? Speculate briefly about factors contributing to the energy consumption patterns in your country and the surrounding region.

3.Energy reserves

Question 5:

oUnder the ‘Articles by topics’ drop box (at the top of the website), select Energy and Environment then Fossil Fuels. Click on All our charts on Fossils Fuels, then open the Natural Gas Proved Reserves topic as a map. Find and name three countries with high natural gas reserves and low final energy consumption (use the Primary Energy Consumption topic) (Hint: Open a second window in your browser to view the two maps at the same time). What do you think might explain this? (The answer may be different for each country.)

Since childhood, Linda has always enjoyed the outdoors. She tries to spend as much time outside in the summer as she can because she lives in the Pacific Northwest, where summers are short. Now, Linda is 62 years old and is taking her grandchildren to the same lake house where she spent long days boating, swimming, and playing sports as a child.

Linda has noticed an itchy skin lesion on the superior portion of her right ear within the past two weeks. She is beginning to worry because it doesn’t seem to be healing. She packed a large-brimmed hat for her lake trip to keep her face and ears out of the sun. She wants to make sure she is helping protect her grandchildren from any potential skin damage, too.

If Linda’s lesion is a sign of cancer, which types of skin cancer do you think it could be? What other information would you need to know to make a more educated diagnosis?

1. Linda’s son thinks a biopsy might be necessary and urges her to follow-up with a dermatologist. In your own words, briefly describe the process of a skin biopsy.

2. In your own words, what is the difference between a benign and a malignant tumor?

3. Linda had a grandfather who was diagnosed with melanoma. She is now wondering if she inherited a gene that has caused her to have melanoma, too. Could this be true? Why or why not?

4. How has Linda’s exposure to sun throughout her life contributed to her possible melanoma? (Hint: think about what happens to the DNA of skin cells.)

5. How can Linda help protect her grandchildren when they are spending time outdoors? Be specific, use your own words, and include at least 3 ideas.

Craig works in a factory and is often exposed to extremely corrosive chemicals. He always follows the proper safety precautions when necessary. One day, his coworker tripped on a staircase and Craig rushed to see if he was okay. As he tried to help his coworker stand up, Craig’s hands and arms began to tingle and burn intensely.

He looked around and realized that the box his coworker was carrying had been filled with a corrosive material and had spilled on his bare hands and arms. Craig immediately ran to the sink and began running water over his skin, while his coworkers called 911. He was rushed to the hospital. While riding in the ambulance, he was in excruciating pain. He observed large blisters forming over his right arm, while his left hand seemed to hurt less than the right, but appeared to be more damaged.

The blisters forming on Craig’s right arm indicate that his burns are at LEAST which type?

• Did Craig do the right thing by rushing to the sink to rinse his skin with running water? Why or why not?
• Craig noticed that his left hand appeared to be the most damaged portion of his skin, but it didn’t hurt as intensely as the less damaged skin. In your own words, explain how this is possible.
• Explain, in your own words, why a full-thickness skin graft may be a better choice for Craig’s wounds when compared to a split-thickness skin graft.
• Research new types of burn care/treatment. Briefly describe a new burn treatment technique that has been developed in the past 5 years. (Rasmussen’s Library and journal databases are a great place to start your research.)
