Title: Possible bugs in the model or web front end

Content: 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.

h1 Outstanding bugs

h1 Web front end

* Bug 1: IE8 cost sensitivity page very slow to load
* Bug 2: IE8 cost sensitivity page 'reset' link hard to press
* Bug 3: webtool seems slightly out of sync with spreadsheet

h1 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

h1 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.

h1 Costs to delete

h2 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macro-algae costs needed correcting (as the source had them in biomethane form, not seaweed), plus these costs have been replaced by the more up-to-date TINA bioenergy analysis (http://2050-wiki.greenonblack.com/cost_sources/46)
* Delete energy crop costs/843 and /844, as these have been replaced by the more up-to-date TINA bioenergy analysis (cost_sources/46)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)?

* Bug 11: Total emissions change when the unit of energy is changed in the preferences sheet. It shouldn't.
