Problem

Consider a country with a population
of 20 million people. Suppose 200,000 MJ/person each year is needed
to support a satisfactory UN
Human Development Index.
 How much energy (in MJ) is needed
for each year by the country?
 How much power (in MW) is required?
 How many 1000 MW power plants are
needed?
 How much energy (in MJ) is needed
each day?
 Suppose the energy is obtained by
consuming crude oil with an energy density of 37,000 MJ/m^{3}.
How many barrels of crude oil are required each day?
 If the price of oil is US$50/bbl,
what is the cost of oil per kWh of energy used each day? Hint:
Calculate the energy used each day in kWh/day and the cost of
oil per day in US$/day before calculating the cost of oil per
kWh
