Case
Studies
and
Examples
for
ESS
by
Topic
2
-‐ Examples
of
renewable,
non-‐renewable,
and
replenishable
resources
(not
just
energy
resources!)
and
explain
why
each
is
not
categorized
differently
-‐ renewable:
Dmber,
soils,
sunlight
-‐ replenishable:
groundwater,
stratospheric
ozone
-‐ non-‐renewable:
minerals,
fossil
fuels,
uranium
-‐ Examples
of
dynamic
nature
of
a
resource:
-‐ Uranium
had
liFle
or
no
value
as
a
mineral
unDl
the
age
of
atomic
weapons
and
electricity,
but
once
nuclear
energy/weaponry
was
seen
as
a
symbol
of
poliDcal
power
and
naDonal
pride,
it
became
highly
valued
as
a
resource.
Aeer
Chernobyl,
nuclear
energy
fell
out
of
favor
and
so
decreased
in
value,
but
once
the
focus
on
climate
change
and
global
warming
began,
nuclear
power’s
value
increased
because
it
does
not
release
GHG’s.
-‐ Petroleum
became
much
more
valuable
both
as
a
commodity
and
poliDcally
once
the
BriDsh
navy
switched
from
coal-‐powered
steam
ships
to
oil-‐powered
diesel
engines.
-‐ Be

the
1992

-‐ Give
specific
examples
of
people
choosing
different
energy
resources,
and
explain
why:
-‐ Tibetan/Himalayan
use
of
animal
dung
as
a
cooking/heaDng
source
because
there
are
few/no
trees
available
for
fuel
wood,
and
the
trees
that
do
grow
there
are
very
slow-‐
growing
due
to
climaDc
limitaDons.
-‐ Tuareg/nomadic
people
of
the
African
Sahel
using
dung
for
cooking
source
for
same
reasons
as
Tibetans.
-‐ United
States,
DRC,
and
China
using
hydropower
because
they
have
the
right
combinaDon
of
large
rivers
and
steep-‐sided
gorges
to
build
efficient
dams.
-‐ Historical
example
of
fishermen
and
whaling
communiDes
using
whale
oil
for
lighDng
before
coal-‐fired
electricity
was
invented.
-‐ All
the
case
studies
in
chapter
12
regarding
soil
degradaDon
and
conservaDon:
-‐ What
is
the
acDvity
that
caused
the
soil
degradaDon?
-‐ How
did/does
that
acDvity
degrade
the
soil?
-‐ What
is
the
intervenDon/strategy
that
conserved
the
soil?
-‐ How
did/does
that
strategy
conserve
the
soil?
-‐ All
the
case
studies
in
chapter
11
regarding
water
resources’
degradaDon
and
conservaDon:
-‐ What
is
the
cause
of
the
degradaDon
of
this
water
resource?
How
is
it

the

-‐ Explain
why
the

LEDC
(can
also
focus
on

rural/urban
areas
in
the
same
country).
