Watch the following 4 minute 50 second video Review for Lesson 2.
Review Sheet – Energy Supply and Demand
- Gross Domestic Product (GDP)
- Energy Intensity
- Quadrillion Btus = 1015 Btus
- World Energy Consumption
- Oil is the most utilized energy source in both 2020 and 2050
- Energy Consumption will increase from 2020 to 2050
- United States Energy Consumption
- First in worldwide reserves of coal
- Oil is the most utilized energy source in both 2020 up to 2050.
- Consumption of all energy sources will increase from 2020 to 2050
- 66.5% of petroleum is used for transportation
- More than half of petroleum needs are met by imports
- US has almost one fourth of the world’s reserves of coal
- Doubling time
- Energy reserves and resources
- "Reserves" represent that portion of demonstrated resources that can be recovered economically with the application of extraction technology available currently or in the foreseeable future. Reserves include only recoverable energy.
- “Resources” represent that portion of the energy that is known to exist or even suspected to exist irrespective of technical or economic viability. So reserves are a subset of resources.
- How long will the reserves last?
The questions below are your chance to test and practice your understanding of the content covered in this lesson. In other words, you should be able to answer the following questions if you know the material that was just covered! If you have problems with any of the items, feel free to post your question on the unit message board so your classmates, and/or your instructor, can help you out!
- Why is the energy use per person in the world increasing?
- The United States, with 5% of the world's population, uses about 25% of the world's energy and contributes 25% of the world's greenhouse gas emissions. Explain.
- List the reasons why the United States per capita energy consumption is the highest of any other region in the world.
- List reasons why the United States energy consumption per dollar of GDP is higher than most of the industrialized nations.
- What is the difference between reserves and resources?
- List the changes that you would make in your personal lifestyle if you were mandated to reduce your energy consumption by 25%.
- What variables determine the lifetime of a nonrenewable resource?
