Renewables chart is based on incorrect final demand queries #45

While reviewing some scenario's with @DorinevanderVlies in the myc tool we spotted a difference in Electricity from solar PV in 2 scenario's in the 'Renewables' chart, while we used the same input-statements for PV. There was no curtailment in both scenario's. Link to the multi-year chart can be found here In the picture we see that the difference was 26.27 TJ for the solar pv.

The query for this amount is found in _myc_final_demand_of_renewable_electricity_fromsolar in Etsource.

The structure is as follows: `- unit = MJ

We see that when the final demand of renewable electricity changes, the amount of produced solar pv in the graph changes as well, while the actual produced electricity by solar PV does not change.

I would think that the amount of PV should not be multiplied by the final demand of renewable electricity, since this can give a skewed view on the production of solar PV in the scenario.

It's somewhat difficult for me to assess exactly what the exact issue is here based on your description @kaskranenburgQ. Is it caused by the sustainability_share, is it because households_flexibility_p2p_electricity is part of final demand, or is it something else? The issue title is not very specific either.

In general I would say that I would rather re-align the MultiScenario queries with those in the SingleScenario queries. I'm not sure why the choice was made to make a different set of queries to begin with. In this case, this would mean that we would no longer distinguish between renewable electricity and non-renewable electricity.

Since we are likely to do a project for the MultiScenario tool, I will propose to restructure the queries as well.

Thanks for your response @mabijkerk, I made some changes. Hope it's more clear now.

Would be great if we can make some improvements in this chart in that project!
