Replacing fossil fuels on power generation is a good measure. I would only take it with a grain of salt if such move becomes an excuse to push a move toward EVs like it has been proposed in Fernando de Noronha, Brazil, even though most of the power supplies in Fernando de Noronha still resort to Diesel-fueled generators.

Kyocera (makers of photovoltaic panels) was offering a product akin the Tesla's Powerwall,allowing Japanese with rooftop PV to store and use solar electricity.

I'd rather trust Kyocera over Tesla.

Japan's Malibu Hotel became the world's first commercial building with the capability to run off BEVs plugged into its EV chargers in the hotel parking lot.The hotel was offering employees incentives to purchase BEVs for themselves.The BEVs shown were exclusively Nissan LEAF cars.In the aftermath of an earthquake/Tsunami event,the hotel would have a few days of available stand-alone power,should the grid go down.

My main concern about BEVs is the range-anxiety, but the unstability of the power supply under some environmental conditions is also quite bothersome. A plug-in hybrid OTOH could make sense not only as it addresses more effectively the range anxiety, but also as it may eventually provide backup electric power for the household. I like to consider this ability in a similar way to those old tiller-tractors with a "multipurpose" horizontal single-cylinder Diesel engine usually coupled to the transmission and implements with a set of pulleys and belts. Some even feature a 220-volt power outlet even when they're not coupled to a genset.
