1. Energy price sensitivity 1. An aluminum saucepan weighs
1.2 kg, and costs $10. The embodied energy of aluminum is 210 MJ/kg. If the
cost of industrial electric power doubles from $0.0125/MJ to $0.025/MJ, how
much will it change the cost of the saucepan?

2. Energy price sensitivity 2. An MP3 player weighs 100
grams, and costs $120. The embodied energy of assembled integrated electronics
of this sort is about 2,000 MJ/kg. If the cost of industrial electric power
doubles from $0.0125/MJ to $0.025/MJ, how much will it change the cost of the
MP3 player?
