The conflict between Net Zero Energy Buildings, and the need for EV Charging

There are two climate change related efforts which put conflicting constraints on building electrical service and energy accounting. On the one hand we want “Net Zero Energy Buildings” where, between a combination of energy efficiency and local renewable energy (rooftop solar), the building generates all the electricity it consumes. On the other hand we want people driving electric cars. Since charging electric cars requires electricity, it then becomes that much harder to reach Net Zero Energy goals.

Groan.

One could just, to meet Net Zero Energy Goals, put up more solar panels to match the electricity consumed in electric car charging. Simple, problem solved, right? Wrong. It makes the Net Zero Energy goal more expensive to reach, and therefore company management is more likely to veto the project. And we want more buildings to produce the energy they consume, right?

Let me make a little observation: Electricity used to recharge electric cars is not electricity used in running the building.
