Which one of the following represents the use of a nonrenewable primary energy source? -
Answer✔heating a cabin in the winter using coal
In the United States, the energy end use sector that uses the greatest amount of coal is
________. - Answer✔electricity
Which of the following is an advantage to using wind powered electrical generators? Wind
powered electrical generators ________. - Answer✔use a renewable energy resource
Which of the following are current environmental impacts related to the widespread
generation and use of electricity in modern societies? - Answer✔PCBs from transformers and
cadmium from batteries are significant sources of water and soil pollution.
Most electricity is generated by using ________. - Answer✔primary energy sources to heat
water and produce pressurized steam, which turns the turbines of an electric generator
Electric current is measured in ________. - Answer✔amperes and electrical potential are
measured in volts
For each characteristic of mineral extraction, decide whether it applies to strip mining,
subsurface mining, or both types of mining. - Answer✔Strip mining: used to extract resources
near the surface
overburden is removed the mining site
destroys large areas of wildlife habitat
Subsurface mining: safety requires good ventilation systems
used to extract resources deep underground
one of the most dangerous occupations in the United States

Both: used to extract coal
generate acid drainage
Which of the following is of least concern in the continued reliance upon coal to generate
electricity in the world? - Answer✔the continued availability of coal
Which of the following is most likely to increase the lifetime of known oil reserves in the world?
- Answer✔increased use of electricity and natural gas for home heating
A rancher in Texas drills for water on her property and in the process, hits oil which squirts
strongly from the ground. Within days a system is installed to capture the oil as it shoots up
from the ground. This system of collecting oil represents ________. - Answer✔primary oil
recovery
Most oil in the world is used to ________. - Answer✔fuel cars and trucks
For each characteristic in the table below, decide which fossil fuel (or fuels) it best describes. -
Answer✔1. Used primarily in the United Staes for electricity generation- coal
2. Remains of ancient organisms, modified underground for long periods by temperature and
pressure- coal,oil, and natural gas
3. The world's most abundant fossil fuel- coal
4. A mixture of hundreds or thousands of different hydrocarbon molecules- oil
5. Primary fuel used in the United States for space and water heating- natural gas
6. Created very slowly and considered nonrenewable at current extraction rates- coal, oil, and
natural gas
7.Used primarily in the United States as a source of vehicle fuels - oil
8.Produces the least carbon dioxside per unit energy when combusted- natural gas
The use of natural gas to generate electricity is increasing because ________. - Answer✔natural
gas is more efficient than coal and releases fewer pollutants
Natural gas is increasingly transported ________. - Answer✔in liquid form between continents
The problem of the disposal of high-level radioactive wastes from nuclear power plants could
be addressed in part by fuel recycling. Why isn't fuel recycling of nuclear waste a widespread
practice where nuclear power is used? Fuel recycling ________. - Answer✔produces plutonium,
which can be made into nuclear bombs
Interest in nuclear power plants is increasing because ________. - Answer✔of increasing costs
of other forms of alternative energy and concerns about global warming
