ROCK CLIMBING COOT ROCKS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Our climbing shoes, Dodge Caravans, mountain guide, and Dwayne "The ROCK" Johnson run entirely on ENERGY.

 Dwayne's metabolic energy is obviously different than the gasoline used to manufacture and run material possessions. However, Dwayne eats food (muscle milk) that uses the same resources as the van and climbing shoes.  So does his family. 

The mission of "THE ROCKING COOT" is to compare both renewable and non-renewable resources and their impact on our environment, lifestyle , and future. 

Types of resources:






Heat - thermal and geothermal

  1. Fuel Source

    Energy Produced (MJ/g)

    Carbon Emission (g/MJ)




    In the USA corn ethanol can produce 0.031 MJ of energy per gram combusted of ethanol.  Per MJ of energy created there are 103 grams of Carbon emitted.  This varies due to the type of ethanol used, and where it was made.


  2. COAL!!!

    There, are four main types of coal-
    Lignite-34 and less% carbon
    subbituminous-35-45% carbon
    bituminous-45-86% carbon
    anthracite-86-97% carbon

    Bituminous is the most popular coal in the United States, as it produces the most heat of all of the coals.

    In 1999, the United States produced approximately 1,787,910,000 metric tons of CO2 through the combustion of coal!

    Coal produces .254 kg CO2/MJ

    Coal produces 2.095 lbs CO2/KWh. That is nearly 2x as much CO2 as gasoline produces per KWh, and comparable to the CO2 production of petroleum.

    For every, mol of carbon in coal, one mol of CO2 is produced. However, for every 1kg of coal, 1.83 kg of CO2 is produced, nearly double the original weight of the coal.

    More fun facts about coal-

    • Coal contributes 66% of the United States' SO2 emmisions
    • Coal comprises 36% of man made carbon emmisions


  3. Gasoline has an energy content of 4.44 joules/gram. It produces 19 pounds of carbon dioxide per gallon.

    Bio diesel has an energy content of 3.78 joules/gram. It produces 22 pounds of carbon dioxide per gallon.

  4. HYDROGEN<!-- @page

    Unknown macro: { size}


    Unknown macro: { margin-bottom}


    As opposed to other sources of fuel, Hydrogen emits no carbon dioxide or any other greenhouse gases. Instead, its only emission is pure water.

    There are three common methods used to create H fuel: Fossil Fuels, electrolysis and nuclear power. However, of these three most methods, the most common and least expensive method requires extensive use of fossil fuels in order to split hydrocarbons.

    Pound-per-pound Hydrogen contains three times as much energy as natural gas.

    Although it may be a source of energy and it may be able to power a car, Hydrogen is not a fuel it is simply a method of storing energy for later use.

    It is somewhat difficult to store. There are three methods of storing Hydrogen: Compression, liquidation and solid state. Compressing hydrogen is by far the easiest way however it takes up to three or four times as much space as natural gas. Liquidation requires temperatures that approach absolute zero. In solid state, hydrogen can only be kept for short periods of time (a few hours).

    Energy density of hydrogen = 13,000 Joules/gram

    Carbon emissions = 0

  5. Wind Power



    Produces no greenhouse gases.

    Wind is unpredictable


    Turbines are 'eyesores'

    Can cut down transportation (i.e. power lines) for remote locations. 

    Influences bird migration

    *Energy return on investment (*EROI) = (cumulative electricity generated) / (cumulative primary energy required)
    Based upon empirical gathered date from 158 turbines worldwide: 18.1
    Based upon projected analyses of future turbine technology: 26.2

    Solar Power




     To become usable, solar power must be converted from AC to DC power. This conversion causes a loss of 4-12% energy

    No Pollution

    Extremely expensive


    Requires complementary and storage power facilities, due to the fact that sun isn't around all the time

    More expensive than grid electricity


    To become usable, solar power must be converted from AC to DC power. This conversion causes a loss of 4-12% energy


    Based upon empirical gathered= 17
    Based upon projections = 3

    (smile) Interesting tidbits:
    -¼ of 1% of the earth's surface, if covered in solar panels, could fuel the world!
    - When it comes to converting solar power into usable energy, 10% of the raw energy becomes usable. Biofuel, in comparison, only provides .13%. Even if biofuel's technology begins to use algae, which is expected to produce the highest efficiency, it will only be 1.3% efficient.
    - Not to burn any biofuel groups or anything, but the EROI for biofuel is a negative value (consider running the tractors and the oil produced in making fertilizer)
