Prices exaggerated for ventilation system, electric aluminum roller shutters

I think he rather means electric for short distances and combustion engines for long ones.

Yes, but of course in the same car. Nuclear and coal power are not "clean" just because you can’t measure any puffs at the back of the car. But driving the car from the street into the garage (for me half a km) without turning on the combustion engine, only using the braking energy from yesterday, that is a real improvement.

I love synergies. Small electric car for the city. Big guzzler for long distances. Then cruise control at a moderate speed, and that consumes much less.

okay, it's going fine. 4 photovoltaic systems currently with a total of 34KWp, soon 30KWp will be added to the office. In addition, exclusively! contracts with Green Planet Energie (purely renewable). Unfortunately, the Tesla Superchargers source their power mix. But the above does not work for everyone and I don't want to hijack the thread further. Sorry in advance as this is really off-topic.

Cool. I would like that too... I can manage a maximum of 18.8 on my roof. North is already taken there. on topic: I have roller shutters and venetian blinds. Back then for price reasons. Venetian blinds were about 50% more expensive than roller shutters

I have roller shutters and venetian blinds. Back then for price reasons. Venetian blinds were about 50% more expensive than roller shutters.

Mixing them, as I recommend with PVC/aluminum building elements, is of course also possible here. But I mainly meant to definitely connect roller shutters and venetian blinds in series. Of course, only at selected locations, if you are not Rockefeller.
