Basics of Energy Use
United States is a developed and Industrialized Nation.
Energy is a part of everything we do.
Residential Energy Use
Other" includes small electric devices, heating elements, motors, swimming
pool heaters, hot tub heaters, outdoor grills, and natural gas outdoor lighting.”

Transportation Energy Use
Energy and the Environment
Energy sources have different impacts or effects on the
environment. Some of these effects may include:
• emissions
• waste
• land or water use impacts
• others.
Greenhouse Gas Basics
Did You Know?
Most of our carbon dioxide
emissions come from using coal
and petroleum fuels.
Learn more about each major
energy source's impact on the
environment below.

Connection
We use a lot of energy! Most of the energy we
use today results in warming the earth.
What happens on a warmer Earth?
Do the Hot EaArth, Warm Earth activity to find
out!
The earth/eaArth water cycle
• This activity is simple yet very effective for
illustrating how a warmer earth changes our
water cycle
• Since the water cycle is taught in every K-12
school, why not take the opportunity to enrich
our student’s learning to include motivation
for changes in energy production and use?
The earth/eaArth water cycle
• Fill one styrofoam cup 2/3 full of
warm water. This is water you
could bathe a baby in, warm, but
not too hot!
• Put the cup in a quart zip-lock bag
and seal it.
• Repeat with a cup of really hot
water or coffee fresh from the pot.
Do NOT put your finger in this
liquid!
• Observe and note any differences
between the two systems.
Please volunteer
to draw
the water cycle!
What happens on a warmer earth?
• Check your cups! Can
you see that more
heat allows more
evaporation, and thus
more condensation?
• Remove your cups and
squeegee the water to
a corner of the bag.
How does the different
amounts of water
relate to flooding?
Something else
to consider
• What you can’t see
is important, too!
The same amount of
energy absorbed
during evaporation is
released during
condensation. In the
atmosphere this
results in strong
winds.
• Is this elaboration?

What happens on a warmer Earth?
How do we solve this problem?
Solutions
• Change the way we generate energy to
sustainable forms
• Reduce the amount of waste we produce
• Change our energy usage behavior to
conserve more energy
• Improve our technology to improve energy
efficiency
• and many more…
Definition of Terms
• Energy Conservation: is any behavior that results in the use
of less energy. Turning the lights off when you leave the
room and recycling aluminum cans are both ways of
conserving energy.
• Energy Efficiency: is the use of technology that requires
less energy to perform the same function. A compact
fluorescent light bulb that uses less energy than an
incandescent bulb to produce the same amount of light is
an example of energy efficiency. However, the decision to
replace an incandescent light bulb with a compact
fluorescent is an act of energy conservation.
