QUESTION - Place the following energy sources in order of their least net carbon dixide emission into the atmosphere, where '1. = lowest net carbon, and 5. = highest net carbon.
In your calculation, take into account:
1. How much carbon dioxide (or CO2 equivalent) is emitted per unit energy generated?
2. If the source is renewable, how much carbon dixide (or CO2 equivalent} is removed from the atmosphere each year by that resource.
3. How much energy is needed to produce and deliver that energy source?
