Chapter 15: Nonrenewable Energy
|
Section 1: What is Net Energy and Why is it Important?
Concept 15-1: Energy resources vary greatly in their net energy yields--the amount of energy available from a resource minus the amount of energy needed to make it available. Section 2: What Are the Advantages and Disadvantages of Using Oil?
Concept 15-2A: Conventional crude oil is abundant and has a medium net energy yield, but using it causes air and water pollution and releases greenhouse gases to the atmosphere. Concept 15-2B: Unconventional heavy oil from oil shale rock and tar sands exists in potentially large supplies but has a low net energy yield and a higher environmental impact than conventional oil has. Section 3: What Are the Advantages and Disadvantages of Using Natural Gas?
Concept 15-3: Conventional natural gas is more plentiful than oil, has a medium net energy yield and a fairly low production cost, and is a clean-burning fuel, but producing it has created environmental problems. |
Section 4: What Are the Advantages and Disadvantages of Using Coal?
Concept 15-4A: Conventional coal is plentiful and has a high net energy yield at low costs, but using it results in a very high environmental impact. Concept 15-4B: We can produce gaseous and liquid fuels from coal, but they have lower net energy yields and using them would result in higher environmental impacts than those of conventional coal. Section 5: What Are the Advantages and Disadvantages of Using Nuclear Power?
Concept 15-5: Nuclear power has a low environmental impact and a very low accident risk, but its use has been limited by a low net energy yield, high costs, fear of accidents, long-lived radioactive wastes, and its role in spreading nuclear weapons technology. |
