Fossil Fuels
 Come from remains of organisms
 Coal
 Petroleum
 Natural Gas
 Many problems with their use
 Availability
 Pollution
Availability
 Not renewable
 Can’t be man-made
 Limited supply
 Difficult/Dangerous to reach
 Dig deeper for oil
 Further into natural areas
 Combustible (explosions)
Pollution
 Burning of fossil fuels releases carbon
dioxide
 Increased on earth by 20%
 Greenhouse effect increases temperature
 Other sources Oil spill
 Habitat alteration
 Mostly air pollution
Biomass Fuels

Alcohol
 Renewable resource
 Made by bioconversion
 conversion of organic material to fuel
 Ex. plants to alcohol
 Sugarcane & corn
 Ethanol
 Liquid
 Burns cleanly
To make ethanol
 Made by yeast
 Fermentation The chemical breakdown of a
substance by bacteria, yeasts,
or other microorganisms
 Yeast turning sugar to alcohol
