Problems
2.1 Using the resources mentioned in Chapter 1, obtain the latest estimate of the world primary energy consumption. How does this number compare to the primary energy available from various renewable resources?
2.2 What are the major differences between macroscopic and microscopic forms of energy? How will you classify the ocean energy resources?
2.3 What is solar constant? What is its numerical value? Why does it differ from the number (340 W/m2) shown in Figure 2.3?
2.4 What are the different types of geothermal energy resources?
2.5 What is the key difference between biomass energy and other renewable energy sources?
2.6 What are the two types of hydropower plants? Which of the two has the potential to generate electricity on a scale comparable to thermal power plants?
2.7 Conversion of primary energy sources into electricity involves several intermediate transformations into other energy forms. Describe for each primary source the sequential transformation steps and identify the intermediate energy forms in its conversion to electricity.
2.8 What is a Lindal diagram? Using the resources mentioned in Chapter 1, identify two geothermal reservoirs closest to your location. Develop a Lindal diagram for each reservoir.
