[Qgis-psc] Environmental policy

[Andreas Neumann]

Hi Matteo,

I agree with most of your comments, but have one reply for your comment on
trains running on nuclear power:

In countries, where you have synchronized time tables (most countries have
them meanwhile), where the trains always leave shortly after the hour and
half-hour, you need most energy when all the trains throughout Switzerland
leave their stations (only hydro and gaz power stations can meet those
short-term peak - nuclear plants can only generate bandwidth energy, no
peak energies). Once the trains are rolling, energy demand is a lot lower.
For such situations, nuclear with constant energy production is not very
useful. In Switzerland, the train system has an extensive network of
hydropower stations (Pumpspeicherkraftwerke) where they can open the gates
to exactly meet the peak energy demands according the train schedules every
day. For this reason, trains typically run on hydro or gaz power. Also,
when trains slow down or run down a slope, they contribute a significant
amount of energy back in to the train grid system, something most cars
(apart from hybrid/electric/plugin hybrid) still don't do, let alone planes
...

Greetings,
Andreas
