Title: Energy Sources renewable vs non-rewnewable


1
Energy Sources renewable vs non-rewnewable
  • Renewable cant be exhausted
  • Solar
  • Geo-thermal
  • Tidal
  • Wind
  • Hydro
  • Non-renewable-can be exhausted
  • Fossil fuels (oil, coal etc)
  • Nuclear

2
How much do we use?
  • World energy consumption
  • US energy consumption

How much do we use?

How much do we use?
  • Almost 95 of the energy we use comes from
    non-renewable energy sources!
  • One of these days we will run out, and then what?
  • What are some short and long term answers to this
    question?

Fossil fuels

FOSSIL FUELS
  • Carbon or hydrocarbons (a compound made of
    hydrogen and carbon) found in the earths crust
  • Formed from the bacterial decay of plant and
    animal life in ancient (a few hundred million
    years ago) seas.
  • The decomposing material was covered with mud and
    sediment
  • This increased the pressure and temperature on
    the material and deprived it of oxygen.
  • A variety of hydrocarbon molecules are created in
    solid, liquid and gas states.
  • The gas and liquid could travel through the
    porous rock and collect in geological traps (rock
    features that prevent further movement of the
    hydrocarbons).

Why is there oil in Texas?
9
A little history.
  • 1859 Colonel Drake(a title he adopted to impress
    the locals) first drilled for oil and found it in
    Titusville, PA.
  • Area was already known to have many active
    surface springs or seeps. Oil had been fond by
    accident via drilling for water.
  • Other wells were drilled and the oil was refined
    into kerosene.
  • Oil was soon found in Ohio, Indiana, California
    and Texas.

What about Kentucky or Tennessee?
12
Oil in KY
  • Well that didnt really happen but there are oil
    fields in KY and TN!
  • Largest in KY is Big Sinking, spanning Estille,
    Lee, Powell and Wolfe counties.

All good things must come to and end..
  • It looks like there is a lot left, but it wont
    last very long.
  • It takes about 11 years from the time an oil
    reserve is discovered until the oil reaches
    production.
  • Also, the production of any energy resource has
    to be economically feasible it cant take more
    energy to get the energy produced than the energy
    itself produces.
  • Q8 denotes the amount of a resource available for
    all time, until it is exhausted

16
M.K. Hubbart The Nostradomus of petroleum
  • Predicted Q8 to be 165 X 109 barrels of oil for
    the US in 1956 (this did not include Alaska or
    other non-conventional sources).
  • Much smaller value than his contemporaries and he
    predicted that US oil production would peak
    between 1966 and 1971 and then fall off,
    independent of anything the oil industry did.
  • Not a popular prediction, but it rang true, US
    oil production peaked in 1970.
