Title: Depletable, Non-recyclable Energy Resources


1
Depletable, Non-recyclable Energy Resources
  • Oil, gas, coal uranium

2
  • Energy one of the critical resources
  • Also from food, meat, plants that depend on
    energy from sun
  • Raw material from earths crust ? finished
    product - with energy
  • When price peaks find substitute
  • Hubberts peak bell shaped?
  • No idea when oil gets over - think of substitute
  • Will transition to substitutes be smooth?
  • Is market mechanism allocating resources
    efficiently?

3
Natural Gas
  • 1974-75 severe shortage - people ready to pay
    more but no supply
  • In efficient allocation this magnitude of
    shortage is should not happen. Why?
  • Source of the problem govt. control
  • ? in automobiles - ? demand for gasoline - while
    exploring for crude oil - also large quantity of
    natural gas was found replaced manufactured gas
    coal - pipe lines laid - after II WW important
    source of energy - US Natural Gas Act 1938

4
  • Regulated price Effect of regulation no
    conservation - consumption increased drastically
  • From supply side production until its
    profitable When MC is higher than the price
    no production although there was demand - ?
    distorted allocation
  • Time of transition was much earlier under price
    control - we will not use all gas at the price
    consumers are willing to pay transition to
    substitute before technologies are developed to
    use it
  • Transition is abrupt as price rises jump to new
    price - technology burden on consumers

5
  • Price controls are not permanent can change
    with politics
  • Ceiling lifted ? price rise - if producers are
    expecting larger rise - stop production and wait
    for higher prices - consumers have severe
    problems
  • Price controls on n-gas created turmoil as it
    took away economys ability to respond to
    changing situation regular incidents of control
    will ? collapse of economy - not due to pure
    market behaviour
  • Why such behaviour of govt.?
  • Rent-seeking behaviour

6
  • When govt. attempts to ? security rent through
    price controls ? over allocation to current
    generation under-allocation to future
    generations ? they are worse off transfer from
    future to current generation
  • Price controls are politically attractive as
    current consumers mean current votes - but also
    inefficient as losses to future population
    producers gt than gain to current population
  • In the LR price-controls harm consumers than
    helping them as controls distort allocation
    towards present
  • President Bush p-decontrol (1989) in stages by
    1993 no p-control - demand is increasing
    production has not kept pace - price ? - imports ?

7
  • LNG is attractive from air-quality point of view
    - storage transport has potential hazards -
    burns hotter spreads more rapidly than oil or
    gasoline cannot be put off can injure the
    people damage the property up to a distance
    from the fire itself
  • Although safety records have been good, potential
    for terrorism has raised security concerns
    facilities tempting target for terrorists high
    security risks especially at coastal areas
    (Mumbai has n-gas pipe lines now and had even in
    the past) to construct new LNG terminals aroused
    local opposition political considerations are
    affecting will affect the importing nations and
    supplying economies.

8
Oil the cartel problem
  • Seller power over resources - due to lack of
    effective competition leads to inefficient
    allocation
  • Oil produced mainly by OPEC countries
    monopoly more scarcity rent than in comp. -
    force higher price by slower production -
    monopolistic transition to a substitute later
    than in competitive transition - ? less net
    present value to the society from these resources
  • Cartelisation effective - Is its profitability
    unique to oil? Will oil cartels lead a new wave
    for natural resource cartelisation?

9
  • Must isolate the factors that that make
    cartelisation possible. Many, but 4 stand out
  • Price elasticity of demand for OPEC oil in SR
    LR depends on opportunities for conservation
    availability of substitutes
  • Y-elasticity of demand for oil Y ? ? ? DD
  • Supply responsiveness of oil producers who are
    not OPEC members want to max their profits
  • Compatibility of interests amongst OPEC member
    countries members may have a strong incentive
    to cheat steal the market

10
Transition Fuels
  • Some day will happen
  • India Reva (10 years ago), solar cooker..
  • Future transition to renewable source of energy
    - what happens in intermediate period?
  • Some believe that no transition fuel required
    -transition rapid - no transition fuel required
  • Most believe that transition fuel will play
    important role
  • Transition fuel for future coal uranium
  • Their environment impact is different.

11
  • Coal main drawback air pollution sulphur
    dioxide emissions culprit in acid rain problem
    major source of particulate emissions carbon
    dioxide coal users fail to consider env costs
  • Uranium used in nuclear electrical generation
    stations safety limitation concerns are for
    nuclear accidents storage of radioactive waste
  • Will market make right decisions? - taking into
    account current decision making environment No
  • Many issues involved

12
  • Electricity by nuclear reactors requires
    radioactive elements - if elements escape into
    atmosphere come in contact with humans - birth
    defects, cancer, deaths.
  • Nuclear accidents Chernobyl - Hiroshima,
    Nagasaki not accidents - very harmful effects
  • Losers can/must be compensated by gainers
  • N-power is efficient - gain to gainers gt loss to
    losers
  • Japan, France using n-power Sweden closed
  • Disposable sites nobody wants ? in land value

13
  • Those consume will be taxed to pay compensation
    to pay those who stay near disposal sites - if
    people accept - nuclear power is viable option -
    costs of disposal borne by consumers - e. g.
    Naurita, Colorado
  • If taxes get too high to obtain disposal sites,
    n-power may become non-competitive. Then it is
    not an efficient source
  • Are future generations adequately represented in
    this transaction? - quick answer no, although
    it is not right ? in value of land reflecting
    risk if land not cheap will not stay there
    accept risk in return for cheaper land values

14
Electricity
  • Transition fuels environmental problems
  • Alternate fuels solar energy play increasing
    role penetrate market slowly as get more
    familiar accessible
  • How is these transitions are managed by
    electrical utilities sector?
  • High prices of oil n-gas ? cost of generating
    stations ?? electrical demand
  • More conservation is needed differ capacity
    expansion
  • Pricing system of electricity is ill-designed to
    lead to conservation MC is gt rate - investing
    in conservation is saving less if the rate is low
  • Wind or solar? solar water heating

15
  • Energy demand is spread over the year
  • Should be able to satisfy peak period DD in
    other periods underutilised
  • Peak periods special costs on utilities
  • peaking units higher MC fired in peak period
  • need for capacity expansion base-load plants
    need expansion due to p-period demand - slowing
    growth in this DD can delay the need for new
    more efficient generating plants can be made
  • Peak-load pricing economic load management
    technique charge full MC
  • Costs dont include all costs of env damage ? low
    priced ? highly polluting - TFCs

16
  • In LR use of renewable energy sources
  • More pollution if poor countries were using
    fossil fuel -
  • Can we manage transition effectively?
  • Renewable energy in different forms
  • Hydropower
  • Biomass
  • Energy Solar, wind, geothermal, wave
  • How much which - depends on their relative cost
    consumer acceptance
  • Hydrogen can ? rising water dangers

17
Summary
  • Relationship between govt market is not always
    harmonious efficient
  • Price controls ? no conservation discourage
    exploration supply to cause biases in
    substitution penalize future consumers create
    potential for abrupt, discontinuous transition to
    renewable resources
  • Not too much regulation
  • But govts role important
