Solve the following questions:
Question I: Locate the current world price of oil (US$/bbl), coal (bituminous coal, per tonne), and natural gas (per 1000 m3).
Part A: For each fossil fuel, calculate the cost of energy per GJ assuming that the fuel can be converted to usable energy with an efficiency of 100%
Question II: One tonne of good-quality oil shale will produce 30 gal of oil.
Part A: What is the energy content of this shale relative to 1 t of bituminous coal?
Any help would be greatly appreciated! Thank you so much!
