Chapter 3 Fossil Fuel Resources and Use 3.1 A person's primary energy needs are supplied exclusively by burning oil (with an energy content of 3.85 × 107 J/L). If a person's average power consumption is 12 kW, how long would it take that person to use one barrel of oil (158.97 liters)? Solution The power 12 kW is the same as energy consumed at a rate of 12,000 J/s. Thus the amount of oil required per second is (12,000 J/s)/(3.85 × 107 J/L) = 3.12 × 10–4 L/s. Thus to consume...
