What is net energy yield and why is it important
in evaluating energy resources?
10 Nonrenewable 1
3
Net energy yield is the usable amount of
high-quality energy available from an energy
resource. Energy resources that are worth
extracting have a high net energy yield.
10
Nonrenewable 1
4
Explain why some energy resources need help in
the form of subsidies to compete in the
marketplace, and give an example.
20 Nonrenewable 1
5
An energy resource with a low or negative
net energy yield can have a hard time competing
in the marketplace with other energy alternatives
that have medium to high net energy yields unless
it receives financial support from the government
(taxpayers) or other outside sources.Nuclear
power is an example of a low net energy yield
resource.

What is crude oil (petroleum) and how are oil
deposits detected and removed? .
30 Nonrenewable 1
7
Petroleum, or crude oil, is oil as it comes
out of the ground. This black, gooey liquid
consists of hundreds of different combustible
hydrocarbons along with small amounts of sulfur,
oxygen, and nitrogen impurities. To extract the
oil, a well is drilled vertically or horizontally
into the deposit beneath the ground. Then oil,
drawn by gravity out of the rock pores flows into
the bottom of the well and is pumped to the
surface. In the process of refining, it is heated
to separate it into components with different
boiling points.

What is the peak production for an oil well and
for the world oil deposits?
40 Nonrenewable 1
10
Peak production for an oil well is when the
pressure in a well drops and its rate of
conventional crude oil production starts to
decline. Peak production for the world is the
point when we reach the global maximum overall
rate of conventional crude oil production.

11
Define natural gas, liquefied petroleum gas
(LPG), and liquefied natural gas (LNG). .
50 Nonrenewable 1
12
Natural gas is a mixture of gases of
which 5090 is methane (CH4). Conventional
natural gas lies above most reservoirs of crude
oil.When a natural gas field is tapped, propane
and butane gases are liquefied and removed as
liquefied petroleum gas (LPG). So that it can
be transported across oceans, natural gas is
converted to liquefied natural gas (LNG) at a
very low temperature and high pressure. This
highly flammable liquid is then put aboard
refrigerated tanker ships. After arriving at its
destination, it is heated and converted back to
the gaseous state at regasification plants before
it is distributed by pipeline.
50
Nonrenewable 1
13
What are proven oil reserves and what five
factors determine such reserves?
10
Nonrenewable 2
14
Proven oil reserves are identified deposits
from which conventional crude oil can be
extracted profitably at current prices with
current technology.Five factors that determine
reserves are demand, technology used to make it
available, rate at which it can be removed, cost
of making it available, its market price.

15
What are the major advantages and disadvantages
of using conventional natural gas as an energy
resource?
20
Nonrenewable 2
16
Advantages and of using conventional natural gas
as an energy resource include ample supplies,
high net energy yield, low cost, less air
pollution than other fossil fuels, lower CO2
emissions than other fossil fuels, easily
transported by pipeline, low land use, and good
fuel for fuel cells, gas turbines, and motor
vehicles. Disadvantages include nonrenewable
resource, releases CO2 when burned, government
subsidies, environmental costs not included in
market price, methane (a greenhouse gas) can leak
from pipelines, difficult to transfer from one
country to another, and can be shipped across
oceans only as highly explosive LNG.

17
What is coal and how is it formed? How does a
coal-burning power plant work?
30
Nonrenewable 2
18
Coal, a fossil fuel, is a rock that burns and
was formed in several stages out of the remains
of land plants that were buried 300400 million
years ago and exposed to intense heat and
pressure over millions of years.Power is
generated by burning pulverized coal to boil
water and produce steam that then spins a turbine.
30
Nonrenewable 2
19
What are three major problems resulting from the
use of coal? Explain why there is no such thing
as clean coal.
40
Nonrenewable 2
20
China burns more coal than any other nation
and this has helped fuel its rapid economic
growth. In 2009, China was building the
equivalent of one large coal-fired power plant
per week. Most of them lacked modern air
pollution control. China has become the worlds
leading emitter of CO2 and of sulfur dioxide.
Burning coal and removing pollutants from the
emissions produces an ash containing highly toxic
chemicals such as arsenic, cadmium, chromium,
lead, mercury, and radioactive radium. Much of
this is then stored in holding ponds. Coal can
be burned more cleanly, but there is no coal that
does not pollute.

21
Describe the nuclear fuel cycle. .
50
Nonrenewable 2
22
50
Nonrenewable 2
The nuclear fuel cycle includes the nuclear
power plant, the mining of uranium, processing
and enriching the uranium to make fuel, using it
in a reactor, and safely storing the resulting
highly radioactive wastes for thousands of years
until their radioactivity falls to safe levels.
23

What is energy efficiency? .
24
The best way to conserve energy is to improve
energy efficiency the measure of how much work
we can get from each unit of energy we use.
10
Renewable 1
25
Explain why we can think of energy efficiency as
an energy resource.
20
Renewable 1
26
 To most energy analysts, reducing energy
waste is the quickest, cleanest, and usually the
cheapest, way to provide for our energy future.

30
Renewable 1
Three reasons we waste energy Fossil fuels and
nuclear power are artificially cheap. There are
few government incentives to invest in energy
efficiency. People tend to resist change.
29
What is a solar cell (photovoltaic or PV
cell) and what are the major advantages and
disadvantages of using such devices to produce
electricity?
40
Renewable 1

40
Renewable 1
Solar energy can be converted directly into
electrical energy by photovoltaic (PV) cells,
commonly called solar cells. Most solar cells are
thin wafers of purified silicon with trace
amounts of metals that allow them to function as
semiconductors to produce electricity.
  Advantages of using solar cells to produce
electricity fairly high net energy yield, work
on cloudy days, quick installation, easily
expanded or moved, no CO2 emissions, low
environmental impact, last 2040 years, low land
use (if on roof or built into walls or windows),
and reduces dependence on fossil fuels.
Disadvantages need access to sun, low
efficiency, need electricity storage system or
backup, environmental costs not included in
market price, high costs (but should be
competitive in 515 years), high land use
(solar-cell power plants) could disrupt desert
areas, and DC current must be converted to AC.
31
What is biomass and what are the major
advantages and disadvantages of using wood to
provide heat and electricity?
50
Renewable 1
32
Biomass is plant material that can be
burned directly. Using wood to provide heat and
electricity has advantages that include
potentially renewable forest and can be local,
and disadvantages that include increased
deforestation, not enough, and air pollution. .

Renewable 2
Hydropower is any technology using the kinetic
energy of flowing or falling water to produce
electricity. Hydropower is the leading renewable
energy source.

  Summarize the global potential for wind power.

36
20
Renewable 2
Wind is widespread and inexhaustible. Wind power
has the potential to produce 40 times the worlds
current use in electricity.

What is geothermal energy and what are three
sources of such energy? .
38
30
Renewable 2
Geothermal energy is heat stored in soil,
underground rocks, and fluids in the earths
mantle that can be tapped into to store energy to
heat and cool buildings and to produce
electricity.

 What are the major advantages and disadvantages
of using hydrogen as a fuel to use in producing
electricity and powering vehicles?
40
40
Renewable 2
Advantages of hydrogen Can be produced from
plentiful water Low environmental
impact Renewable if produced from renewable
energy resources No CO2 emissions if produced
from water Good substitute for oil. Competitive
price if environmental and social costs are
included in cost comparisons. Easier to store
than electricity. Safer than gasoline and natural
gas. Nontoxic. High efficiency (4565) in fuel
cells. Disadvantages of hydrogen Not found as
H2 in nature. Energy is needed to produce
fuel. Negative net energy. CO2 emissions if
produced from carbon-containing
compounds. Environmental costs not included in
market price. Nonrenewable if generated by fossil
fuels or nuclear power. High costs (that may
eventually come down). Will take 25 to 50 years
to phase in. Short driving range for current
fuel-cell cars. No fuel distribution system in
place. Excessive H2 leaks may deplete ozone in
the atmosphere.

What are the major advantages and disadvantages
of using biodiesel and ethanol to power motor
vehicles?
42
50
Renewable 2
Advantages of using biodiesel as a vehicle fuel
include reduced CO emissions, reduced CO2
emissions (78), high net energy yield for oil
palm crops, moderate net energy yield for grape
seed crops, reduced hydrocarbon emissions, better
gas mileage (40), and potentially renewable.
Disadvantages include increased NOx emissions
and more smog, higher cost than regular diesel,
environmental costs not included in market price,
low net energy yield for soybean crops, may
compete with growing food on cropland and raise
food prices, loss and degradation of biodiversity
from crop plantations, and can make engines hard
to start in cold weather.   Advantages of using
ethanol as a vehicle fuel include high octane,
some reduction in CO2 emissions (sugarcane
bagasse), high net energy yield (bagasse and
switchgrass), can be sold as a mixture of
gasoline and ethanol or as pure ethanol, and
potentially renewable. Disadvantages include
lower driving range, low net energy yield (corn),
higher CO2 emissions (corn), much higher cost,
environmental costs not included in market price,
may compete with growing food and raise food
prices, higher NOx emissions and more smog, and
corrosives can make engines hard to start in cold
weather.

What are the major advantages and disadvantages
of relying on the nuclear fuel cycle as a way to
produce electricity?
47
10
Potpourri
The nuclear power fuel cycle has a low
environmental impact and a very low accident
risk, but its use has been limited because of
high costs, a low net energy yield, long-lived
radioactive wastes, vulnerability to sabotage,
and the potential for spreading nuclear weapons
technology.

Define horizontal drilling and hydraulic
fracturing or fracking and explain how these two
technologies are being used to extract tightly
held oil and natural gas from shale rock.
50
Horizontal drilling is subsurface drilling
horizontally to approach a reserve. Hydraulic
fracturing involves using high-pressure water,
sand, and chemicals to extract tightly held oil
and natural gas.

Explain how we can get heavy oil from oil shale
rock and from tar sands (oil sands).
52
30
Potpourri
Tar sand, or oil sand, is a mixture of clay,
sand, water, and a combustible organic material
called bitumena thick, sticky, tar-like heavy
oil with a high sulfur content. If tar sand is
close enough to the surface it can be
strip-mined. First the overlying surface is
clear-cut, next the overburden is stripped away,
and then the tar sand is dug up and taken to an
upgrading plant. There the oil sand is mixed with
hot water and steam to extract the bitumen, which
is converted into a low-sulfur, synthetic, crude
oil suitable for refining

Advantages of geothermal energy for space heating
and for producing electricity or high-temperature
heat for industrial processes very high
efficiency, moderate net energy at accessible
sites, lower CO2 emissions than fossil fuels, low
cost at favorable sites, low land use and
disturbance, and moderate environmental impact.
Disadvantages scarcity of suitable sites, can
be depleted if used too rapidly, environmental
