Question 1169934: 1. Compare methane (CH4), octane (C8H18), methanol (CH3OH) and ethanol (C2H5OH) in terms of the quantities of CO2 that these fuel produce when they burn. Express these quantities as tons of CO2 produced per ton of fuel consumed.
2. Compare the costs per unit of energy for electricity and gasoline. Assume $0.06 per kWh for electricity and $1.50 per gallon for gasoline. Make the same comparison for gasoline at $2.35/gal. Since gas engines are only about 20-25% efficient and elecric cars are 50-80% efficient, which is more economical for transport with respect to fuel costs? If the electricity to charge the electric car's battery is obtained from a coal-fired plant which operates at an efficiency of 33%, how does this change the picture?
1 lb gasoline releases= 19,000 BTU/lb
1 gal gasoline= 5.51 lb
1 cal=4.18 j = 1.16 x 10-6KWh =3.97 x 10-3BTU
