Can Biofuels do the Job?

What do we use energy for? Heating homes, Running our homes Industries: automotive, glass, metal castings, chemical, paper. Running our cars.

Fellow 1’s energy use Fellow 2’s energy use

Where does our energy come from?

Coal fire plant

Coal Mining

Many hydroelectric dams on rivers: Kalamazoo, Au Sable, Grand, Manistee, Muskegon.

Nuclear Cook, Bridgeman, MI: – 2 Units: 1,048 net megawatt (MW) and 1,107 net MW Fermi, Toledo, OH: 1122 Mwe Palisades: South Haven, MI: 778 Mwe

Running cars

There are lots of people in the world who are driving cars

Can biofuels do the job?

Straw vs. charcoal? BTUs (British Thermal Units) A unit of energy = the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit

Gasoline 1 gallon = 125,000 Btu Diesel fuel 1 gallon = 138,700 Btu Ethanol 1 gallon = 84,600 Btu Bio-diesel 1 gallon = 126,206 Btu Can it run our cars?

Can it run our electricity? 1 gram of switchgrass =16 Btu 1 gram of charcoal = 28 Btu 1 gram of coal = 23 Btu Michigan consumed 2.7 trillion BTU in 2009!!!! Switchgrass can yield 2,000 grams per square meter!!!

What do you notice? Where is the yield higher? Where is the yield lower? Where would you grow your biofuels? Do you think the BEST plots will do better next year?
