The source URL has changed. It represents the year 2012 and is only
for buildings, not district heating. So the capacities for urban
central are now set to zero from this source.

This is because old costs default (25) is longer than all heating
technologies (20). Script was distributing across 25 years, then
throwing out boilers older than 20 years, an inconsistent
behaviour.

Now existing boilers are smoothly distributed across 20 years.

This allows them to cover heat demand peaks e.g. 10% higher than
those in the data.

The disadvantage of manipulating the costs is that the capacity is
then not quite right. This way at least the costs are right.

Doing it properly would require introducing artificial peaks, but this
creates new problems (e.g. what is going on with wind/solar/other
demand).

This is required so that other models can do CO2 limits on each type
of aviation separately.

Also allow industrial coal demand to be regional (so we can include
them in regional CO2 constraints).

This is so that the full EU28 ammonia demand can be correctly
subtracted in the build_industry_sector_ratios.py script.

No other downstream scripts are affected by this change.

in build_industry_sector_ratios.py. In the config the units are Mt/a,
they are multiplied by MWh/t, but what is desired is GWh/a.

I.e. split basic chemicals (without ammonia) into MeOH, Cl and HVC.

This now agrees with scheme for industrial sectors tomorrow.

This makes sure the distribution key is correct when only subsets of
countries are used. This is then consistent with the HVC, MeOH and Cl
totals being EU28 totals.

Without this change, industry production is overestimated when using
subsets of countries.

Or the user has to adjust the totals for industrial production
themselves.

This uniformises how demand for basic chemicals is calculated.

We also avoid unnecessary use of ammonia production separately.

For each country we gradually switch industry processes from today's
specific energy carrier usage per ton material output to the
best-in-class energy consumption of tomorrow in the
industry_sector_ratios.csv.

This is done on a per-country basis. The ratio of today to tomorrow's
energy consumption is set with the
config["industry"]["sector_ratios_fraction_future"] parameter.
