Eine sehr detaillierte (wenn auch US-zentrische) Historie der Elektromobilität.

“The first surprise was that the grid showed particularly strong fluctuations every 15 minutes,” says Dirk Witthaut of the Juelich Institute of Energy and Climate Research.”This is the exact time frame during which generators on the European electricity market agree on a new distribution for the electricity generated — this alters how much electricity is fed into the grid, and where. In Europe at least, power trading therefore plays a key role in balancing grid frequency fluctuations.”

More European cities should follow that lead:

The City of Barcelona is migrating its computer systems away from the Windows platform, so reports the Spanish newspaper El País. The City's strategy is first to replace all user applications with open-source alternatives, until the underlying Windows operating system is the only proprietary software remaining. In a final step, the operating system will be replaced with Linux.

To accomplish this, the City will start commissioning IT projects to local SMEs, and at the same time hire 65 new developers to work on software programs. One of the projects will be to develop an online platform (a digital market) that allows small businesses to participate in public tenders.

For the coming year, 70 percent of the City's software budget will be invested in open source software. According to Francesca Bria, the Commissioner of Technology and Digital Innovation at the City Council, the transition will be completed before the current administration's mandate ends in spring 2019.

It’s not a marketing statement, those batteries are designed to last as long as the vehicle

Das Ding ist in meinen Augen eine völlig unsinnige PHEV-Konstellation. "Lipstick on a pig", wie man im Englischen sagen würde...
