Assume the cost of gasoline is $2.2 per gallon and the cost of electricity is $0.10 per kWh. Gasoline weighs 5.5 lbs per gallon and releases 19,000 Btu of energy per pound. a) Calculate the cost of gasoline and electricity for transportation in terms of dollars per joule. b) Which one is a more costly energy for transportation? (hint: more costly means cost more for the same amounts of energy) c) If gas engines are 25% efficient in energy use (can only use 25% of the total energy from the gasoline) and electric engines are 60% efficient, which is more economical for fuel cost? (hint: more economical means cost less to produce the same amounts of energy)
