oil and natural gas supply 62% all energy consumed worldwide
how to transition to new sources?
use until mc of further use exceeds mc of substitute resources More abundant coal Or renewable solar
transition should be smooth
have allocations been efficient?
natural gas huge shortages on 1974-75. why?
rise of automobile rise of demand for gasoline search for new sources of crude oil uncovered large quantities of natural gas
in the 50’s gov’t put price ceilings
the effect of price controls price ceiling reduces MUC (higher future prices no
longer possible), decreasing total mc curve (supply)
consumers better off today (gained BC)
producers not better off: Overproducing giving up scarcity rent could have gotten without price
controls (area D only measures current profit)
consumers also lose in the future as resource depleted, supply curve shifts up (reflecting
higher extraction costs)
when mc reaches price ceiling, QS=0
but demand is not zero at that price: shortages
suppliers willing, demanders willing, but price control will not allow
overallocation to current consumers, underallocation to future consumers
losses to future consumers/producers are greater than gains to current consumers
oil similar price control problems
second source of misallocation: OPEC
restrict supply, raise prices
why OPEC so effective?1. price elasticity of demand for oil
• inelastic, substitutes exist but are expensive2. income elasticity of demand for oil
• income grows, demand grows3. supply responsiveness of non-OPEC members
• OPEC produces 2/3; only Mexico may have influence
oil: national security problem excessive dependence on imports
national security issue dependent on countries with unstable political
history actual price we pay is higher than world price
when national security is an issue market consumes too much oil domestic production is too small
market vs. efficient allocations vulnerability premium reflects additional national security
costs caused by imports
horizontal because each individual supplier has no effect on world price
market allocation demand Q5 Q1 domestically produced Q5-Q1 imported
efficient allocation demand Q4 Q2 domestically produced Q4-Q2 imported
what would happen during an embargo? consume Q1 at price of P2
supply curve assumes enough time to develop the resources
if embargo hits, not enough time – in short run supply curve becomes perfectly inelastic at Q1
price rises to P2 to equate supply & demand
huge loss in CS
self sufficiency? domestic supply = domestic demand
net benefits from Q3 < net benefits from Q4 (efficient allocation
w/imports)
Efficiency loss (shaded triangle): because foreign mc is lower than domestic mc (supply) loss between Q2 and Q4 (where domestic mc > foreign mc)
still better to import vulnerability premium lower than cost of
self sufficiency embargos not certain events possible to reduce vulnerability (strategic
reserves) using more domestically incurs user costs by
lowering amounts available for future
paying vulnerability premium creates more efficient balance btw present/future
how to achieve efficient consumption (Q4 instead of Q5)? energy conservation, e.g. gas tax
reduces consumption, but no affect on share of imports
subsidize domestic supply reduce imports, but not consumption
tariff on imports (P1-P0) or quota on imports (Q4-Q2) price rises to P1, consumption falls to Q4,
imports Q4-Q2
transition fuels how to transition to renewables?
fuels receiving most attention: coal, uranium coal: abundant uranium: not abundant with current reactors
technology is changing this
biggest issue btw these: environmental impact
transition fuels: environmental problems
coal: air pollution (sulfur, particulates, CO2)
uranium: nuclear accidents storage of radioactive waste
energy conservation significant role: defer capacity expansion
cost increases are substantial
by reducing demand for electricity, delay new plants, delay rate increases
current pricing systems rely on AC pricing, lower than true MC of new units
utilities invest in conservation when cheaper rebates for conservation measures in
homes
incentives for solar water heaters
energy audits
load management peak period imposes 2 costs on utilities
requires firing up special generators during those periods (higher MC)
growth in peak period demand => capacity expansion
peak load pricing
