This is a space to list possible bugs in the excel model or web front end. Please assign the bug a number, incrementing one from the last one on the page.
Outstanding bugs
Web front end
- Bug 1: IE8 cost sensitivity page very slow to load
- Bug 2: IE8 cost sensitivity page 'reset' link hard to press
Excel model
- Bug 4: Is the cooling demand in IX.a correct? D12/192752
- Bug 5: The model assumes 77 million bikes in 2050, which seems too high, and the costs are not on the wiki
- Bug 6: labelling in E107 on year sheets is misleading - electricity imports are not related to hydrocarbons. Similarly, sorting out imports (brackets)ambiguity would be useful.
- Bug 7: error in waste volumes. D12/383050
- Bug 10: Transpot double counted in the energy demand chart on the control sheet
- Bug 11: Total emissions change when the unit of energy is changed in the preferences sheet. It shouldn't.
Assumptions
- Bug 8: 2050 working assumption Biomass forestry arisings collection 2050 high end looks absurd.
- Bug 9: The operating cost of conventional vehicles looks high unless it includes tax and insurance. It should not include tax and insurance.
Costs to delete
Bioenergy costs (comments from richard.taylor@e4tech.com)
- Delete cost_source/84 (and therefore remove costs/793, /794, /795 and /796). These macro-algae costs needed correcting (as the source had them in biomethane form, not seaweed), plus these costs have been replaced by the more up-to-date TINA bioenergy analysis (http://2050-wiki.greenonblack.com/cost_sources/46)
- Delete energy crop costs/843 and /844, as these have been replaced by the more up-to-date TINA bioenergy analysis (cost_sources/46)
- I think the costs extracted from cost_source/90 (Jablonski et al. 2010) might need to be double-checked. All of the capital costs in the wiki are given as £/GJ (and hence converted straight into £/MWh using x3.6), however, all the investment costs in the original source itself are given as £/(GJ/year). Alternatively, the y-axis units could be changed £/(MWh/yr)?
Fixed bugs
- Bug 3: Cost VI.a.Bioenergy is not included in the total cost presented by the webtool.
- Bug 12: There is a missing GW unit in sheet I.a, cell F92.
- Bug 13: XVI.b wrong price year - row 37
- Bug 14: I.a - missing GW unit in cell F92
- Bug 15: VI.b Unit error: should have MGBP rather than GBP in cell G233
- Bug 16: IX.a small error in cells referenced by cooling costs on rows 461-463 of sheet
- Bug 17: XII.a. cell E365 referencing wrong cell & throwing off costs
