Comparing Energy Use
Developing countries are those that are poor in terms of their
economy and whose citizens have a low standard of living.
The image below shows the income levels for countries in the
world. Answer the following question in your science journal:
- How do you think energy use is different between people in
low-income countries and those in high-income countries? (give at least 3 differences)
High income Upper-middle income Lower-middle income Low income
Energy Spenders: China and U.S.
China has only recently
surpassed America in energy consumption by 4%
China consumed 2.252
billion tons of oil equivalent in 2009, the U.S. consumed 2.170 billion tons.
Prior to 2009, the U.S. has
been the largest energy consumer since the 1900s.

Energy Consumption vs. Population
In 2007, the U.S. was
the leader in energy consumption.
In 2007, the U.S. had
5% of the World’s Population, but consumes 30% of the energy resources.

Data from 2007
Energy in Industrialized Nations vs. Developing Nations
A citizen of an advanced industrialized
nation consumes in 6 months the energy that has to last a citizen of a developing country his entire life.

Conserving Energy Starts at Home
Special photography
records thermal radiation, and offers clues to where energy is being wasted in this older house in Connecticut.
Red and yellow patches
indicate escaping heat, while new double-pane windows appear cool blue.
By sealing in warmth, the
windows cut heating costs, which can account for up to half a family's energy bill. Where is this house losing
the most heat from?
What can they do to
conserve it?

Energy Management Plan
Managing energy is like managing your budget. You should
follow three steps:
1.
Collect information that tells you what your money (or energy) is being spent on.
2.
Evaluate the information and decide where you can reduce costs or replace with a better solution.
3.
Make a plan that you can follow to reduce your costs.
Think back to the money you have spent this week. Include all costs! List them in Part 1 of the Money Management page.
Hidden Costs in Energy Consumption
Can you think of ALL the ways energy was used to allow
you to wash your clothes in a washing machine?
Direct: Energy to run the machine
Hidden: energy spent in shipping the machine to your house or local store. Hidden: energy spent to pump water to the machine Hidden: energy spent to heat the water used to wash the clothes. Hidden: energy spent to create the metal and plastic on the machine Hidden: energy spent to produce, package and ship the laundry soap.
