Sources of inefficiency • Externalities (market failure) • Government failure (perverse incentives)
Externalities in energy production and consumption • Coal mining • Electricity generation • Oil extraction and refining • Gasoline use in automobiles
S=MPC + MSC P* q* External costs of extracting coal $ S=MPC only pm D qm Quantity of coal mined
S=MPC + MSC P* q* External costs of electricity generation from coal $ S=MPC only pm D qm Quantity of electricity from coal-powered generation

Energy policy objectives • Reduce import dependency ratio so that U.S. is less vulnerable to unstable world markets • Manage domestic prices so that high energy prices do not dampen economic activity • Shift energy use from depletable to renewable sources • Reduce energy demand overall
Supply policy • Open new reserves in the U.S. • Alaskan Wildlife Reserve
Qd At SD: ratio = (Qt – Qd)/Qt At SD2: ratio = (Qt – Qd2)/Qt SD Domestic Supply $ SD2 International Supply SI Pw Domestic Demand Qd2 Qt Quantity of petroleum
Price policy • Strategic oil reserves • Short-term increase in domestic supply • Price controls • Temporary restrictions on prices paid by energy users (this was done in the 1970s)
Price controls (consumers’ price was set) in the 1970s resulted in shortages of gasoline S $ Pm Price control D Qd Qs Qm Quantity of gasoline
Alternative source development • Hydrogen cells • Much of the R&D with federal funding • Wind farms • Clean but loud • Solar power
Alternative approaches to encouraging conservation of gasoline: • Make cars more fuel-efficient • Impact on gasoline use depends upon elasticity of demand for driving • Driving is less costly if cars use less gas to travel any given distance • Make gasoline more expensive • The cost of driving any distance is higher • This may increase the demand for fuel-efficiency, but not for miles driven
Impact on use of gasoline in cars depends upon the elasticity of demand for driving. MC ‘ D’ Changes in fuel efficiency standards so cars use less gasoline: $ MC pm D qm Miles of driving
