Renewable Energy
• Fuel that can be continually produced
• Wind, hydro, geothermal, and electric
power are just some examples
Biomass
• Organic material that can be used as fuel
for industrial production
• Plant matter is the most common form of
biomass energy
Alcohol fuels
• Methanol and ethanol are the most common types of
alcohol fuels
• Ethanol is made from fermenting corn product
• Methanol can be produced a variety of ways including
recycling carbon dioxide (CO2)
Hydrogen
• Cannot be used alone, this must be mixed with another
chemical and will emit water vapor as exhaust
• Hydrogen has high energy content by weight however it
is low in volume
Compressed air

•
•
Compressed air does not carry harmful emissions
10 times cheaper than conventional fossil fuel
Car companies have reported 35 mph with just air alone
By 2010 there are plans to have air cars run over
100mpg and with a top speed of 96 mph
Alternative fossil fuels
• Compressed natural gas (CNG) is as efficient and
cleaner burning than petroleum based fuel
• CNG tanks take up slightly more space because it takes
more to equal its petroleum gas counterpart
• Nearly any modern gasoline engine can be converted to
use CNG
Nuclear power
• All nuclear power is drawn from atomic nuclei via
reactions
• The most common form of nuclear power today is called
fission
• Fission reactors get their energy from the U-235 isotope
of uranium
• Long term nuclear disposal a problem
