Question
Chapter 16, Problem 1TYC
To determine
The proportion of energy now comes from renewable sources and most prevalent form of renewable energy used and the form of renewable energy that is most used to generate electricity.
Expert Solution & Answer
Answer to Problem 1TYC
Major part of renewable energies is used is the generation of electricity and other percent in used as fuel, heating water, and so on
Explanation of Solution
Renewable sources of energy contribute a little in the global population. About 22% of electricity in the United States is generated by renewable source of energy.
The U.S uses only 9.9% of renewable sources which includes hydropower, bioenergy, geothermal, solar, and wind energy.
Most of the prevent form of renewable energy consumed by the United State is bioenergy. Bioenergy is the energy which is most widely used in the U.S. Bioenergy is the energy derived from the biological materials and sources.
The electricity in United States is generated by using the following form of energies:
- Geothermal energy (2.3%)
- Solar energy (5.7%)
- Wind energy (18.8%)
- Hydropower (24.7%)
The generation of electricity is mostly contributed by the 25% of hydropower renewable source of energy. Geothermal energy is the least renewable energy used in the generation of electricity.

Figure 9.9 is a stereogram showing a portion of the area covered by the Whitewater, Wisconsin, topographic map (Figure 9.10, page 160). Use the stereogram and the map to complete the following.
7. The streamlined, asymmetrical hills composed of till, labeled B, are what type of feature?
8. Examine the shape of the features labeled B on the map in Figure 9.10. How can these features be used to determine the direction of ice flow in a glaciated area?
9. Using the features labeled B in Figure 9.10 as a guide, draw an arrow on the map to indicate the direction of ice movement that occurred in this region.
10. What is the likely location of the outwash plain on the map? Identify and label the area "outwash plain." (Hint: Refer to Figure 9.7.)
11. Label the area covered by ground moraine.
12. What term is applied to the numerous almost circular depressions designated with the letter C?

Calculate the elevation of the water table at each well location and write the approximate elevation on the line next to each well. Next, use a colored pencil to draw smooth 10-foot contours that show the shape of the water table. (Start with the 1160-foot contour.) Use a pencil of a different color to draw arrows on the map to indicate the direction of the slope of the water table. a. Toward which direction (downward) does the water table slope? b. Referring to the site of the proposed water well, at approximately what depth below the surface should the proposed well intersect the water table? 2. Assume that a dye was put into well A on May 10, 2017, and detected in well B on May 25, 2018. What was the rate of groundwater movement between the two wells, in centimeters per day?
