Copy of Place the following energy sources in order of their

Copy of Place the following energy sources in order of their least net carbon dioxide emission into the atmosphere, where 1. = lowest net carbon, and 5. = highest net carbon. In your calculation, take into account: How much carbon dioxide (or C02 equivalent) is emitted per unit energy generated. How much carbon dioxide (or C02 equivalent) is removed from the atmosphere each year by that resource. How long it takes that resource to remove it\'s C02 equivalent from the atmosphere. How much energy is needed to produce and deliver that energy source. Wood pellet fuel Agricultural Residue pellets and ethanol (grasses, com Stover, straw, rice husks) Biochar sequestration (produced by Torre faction or pyrolysis). Pyrolysis (Biomass gasification) Copy of Place the following energy sources in order of their least net carbon dioxide emission into the atmosphere, where 1. = lowest net carbon, and 4. = highest net carbon. In your calculation, take into account: How much carbon dioxide (or CO2 equivalent) is emitted per unit energy generated If the source is renewable, how much carbon dioxide (or C02 equivalent) is removed from the atmosphere each year by that resource. 3.How much energy is needed to produce and deliver that energy source. Biodiesel (soybean oil based). Biodiesel (waste oil based) Biodiesel (Algae-based) Grain Ethanol Biogas (recovered biogenic methane=\"landfill methane\")

Solution

Answer

1) For this answer we have keep in mind the energy produced, Carbon reduced by , Time ,energy equivalent for delivery of source, Below are rating with reasons

1.Biochar sequestration (Since it is carbon negative fuel but with high energy generation )

2. Agriculture residue (Takes least time, easily accessible but low energy generation )

3 pyrolysis (High energy generation but takes times )

4. Wood (high heat generation and few decades to generates)

5. Peat (low energy generation and take some time to generates)

2.)

1 Algae Based (Takes least time and fastest carbon fixing)

2. Grain Ethanol (Higher production compare to soybean)

3 Soybean Ethanol(require high energy to convert)

4.Waste Oil (long time for generation)

5. Biogas(Very long duration to be carbon neutral)
