Understand Temoa's results

[robfairh]

Here are some the results for Temoa's current models:

UIUC_2050_cost:

Figure 1:

Figure 2:

Figure 3:

Figure 4:

• Issue number 1: Figure 1 shows that the CO2 emission falls to zero. Figure 2 is consistent with this behavior. However, Figure 3 is not. TURBINE produces electricity somehow without producing CO2. If TURBINE produces electricity means that ABBOTT is producing STM. However, Figure 2 shows that ABBOTT doesn't produceSTM. The only explanation I find is that Temoa is accumulatingSTM```.

• Issue number 2: Figure 4 shows that ABBOTT's capacity is more than 375 MWth in 2021. The model imposes that constraint for all the future years including 2021. The rest of the years seem to meet this constraint.

UIUC_2050_land:

Figure 1:

Figure 2:

Figure 3:

• Issue number 3: similar to number 1 but for the land-use model.

This issue can be closed when an explanation for these phenomena is found and the 3 issues are fixed.

hmm this one's a doozy

This isn't so bad.

1. We should get rid of the minimum activity for wind after 2026. That's when the university's actual PPA ends.
2. I'm actually not bothered by the fact that the cost scenario adds so much wind power. This just means that Temoa believes it is in the University's interest to obtain more PPAs. The results would likely be different if UIUC had to pay a fixed cost for wind and solar energy. Bottom line, this is okay.
3. To solve the TURBINE issue. Try adding a small but non-zero amount of carbon emissions from the Turbine. Perhaps 0.00001 tons/GWh (whatever the units are, I'm forgetting). This should force Temoa to stop using the TURBINE to generate electricity.

Update: @robfairh and I solved the TURBINE problem. data_parser was combining TURBINE and NTURBINE. We have renamed NTURBINE "SPINNY" for the moment, to prevent string overlap. Here is the new result:

@samgdotson Can you PR your fixes?

PR #156 partially fixes this issue, by solving the above-called issue number 1.

This issue number 2 is addressed in a new issue: #162. Closing this issue.
