Alternative Energy Project
You and a partner will randomly select an alternative energy and create an 8-10 minute PowerPoint presentation. You
will present your presentation on ________________ and __________________. Make sure to include a bibliography of
your sources for your presentation and make sure to reference them in your actual presentation. Both group members
must equally contribute to the production of the PowerPoint and presentation. Some sections will require more work
than others. Please dress professionally with your partner. The required items that must be in the presentation:
1. History of the Energy source
a. Who founded this type of energy (developmental pioneers)?
b. When was it invented, developed, or used?
2. Specific use of energy source?
a. What do we use it for?
b. How do we use it?
c. Where is this energy useful (applications); not useful or not efficient?
d. Name all that apply and provide a description of each one.
e. Is it used to produce electricity?
f. Is it used to produce heat?
g. Is it used to move objects (machines)?
3. How has the function of the energy source changed throughout history?
4. How much does your energy source cost?
a. How much do consumers pay to use this energy
b. Is it cost effective to make?
c. What is the estimated cost of maintenance?
d. Are costs per (J) joule, (kJ) kilo joule, BTU available?
5. How much more energy efficient (effective) is this energy source than others in doing a task?
a. Is it better at providing heat, electricity, etc.?
b. How much better or worse (looking for % or factual referenced based data/calculations)?
6. Where is this energy source most often used (where would we see it)?
a. Please show visuals for locations in order for audience to visualize, local, state, U.S., world?
7. What are some positive effects of your energy source on the environment?
8. What are some negative effects of your energy source on the environment?
9. Laws or subsidies for/against your energy source, U.S., worldwide?
10. Are there plans to use this energy source to produce new types of energy in the future?
a. What is the latest research taking place with the energy source, will it have more than one function or
use in the future?
11. Include two recent current events on your energy source, summarize and give your opinion on.
12. Include a strong conclusion on why your energy source should be used over all others or not?

Chapter 20 Sustainable Energy
1. One of easiest ways to avoid energy shortages and to relieve environmental degradation is simply _________
2. There are ways to save energy
a. _________________- produce 4x the light and last 10x as long compared to incandescent bulbs
b. ___________________- even more efficient than fluorescents
c. better insulation, sealing of cracks, new ___________________
d. More efficient ___________________- washers- use 35% less water,
e. orienting your house _____________________ allows for passive solar gain in the winter
f. Turn off appliances to save energy!!
3. Transportation could be far more efficient______________________ emissions
b. 13.3 mpg in 1973, 25.9 mpg in 1988, 20.4 mpg in 2004 (lowered due to cheap gas and SUVs)
c. Some argue that trucks and SUVs are safer during collision, however studies have shown they are
more dangerous than the typical midsize auto due to being hard to control due ______________
d. Hybrid gasoline-electric vehicles- have the highest efficiency up to 55 mpg and lowest emissions in the
e. Diesel- some European models can get up to 78 mpg
B. Tapping Solar Energy
1. Solar collectors can be passive or active
a. ________- glassed walled sunspace/greenhouse have walls that absorb heat that can be used at night
b. __________- generally pump a heat-absorbing fluid (water, air) through a relatively small collector
that can provide heating or hot water
C. High-Temperature Solar Energy
1. _________________ can focus on a central tube where fluid in the tube can reach much higher temperatures
2. Solar box cookers are a great option in developing countries
3. _______________________ capture solar energy by separating electrons from their parent atoms and
accelerating them across a one-way electrostatic barrier creating an electrical current
D. Fuel Cells
1. Devices that use ongoing electrochemical reactions to produce an electric current, similar to batteries but
rather than recharging you add more fuel
a. Advantages- small size, high efficiency, low emission, net water production, no moving parts and high
b. Engineers are focused on improving efficiency of fuel cells for autos but this could take
__________________ to set up with infrastructure
E. Energy from Biomass
1. Biomass has the potential to be a prime source of energy, it is renewable and easy access, accounts for
______ of total world energy use
2. Examples-wood, wood chips, bark, branches, leaves, starchy roots, etc.
3. Developed countries mainly use wood through woodstoves, drawbacks _____________________
4. In Vermont, fossil fuels are expensive, unmarketable ______________ are burned to fuel a 50 megawatt
power plant in Burlington
5. Developing countries depend on ___________________________ as their primary energy source, due to
rapid population growth, deforestation has increased
6. Dung and methane can be fuel
a. Where wood is in short supply, people dry and burn _____________________, drawbacks- not
putting manure on back as fertilizer reduces crop production
b. Methane is the main component in natural gas being produced by anaerobic decomposition of any
moist ______________________ (swamp gas is explosive, swamps are large methane digesters)
-Burning methane produced from manure provides more heat than burning the dung itself
