BYD wants to build an ecosystem

BYD has a major vision. "The goal is to create a zero emissions ecosystem," said Michael Austin, a Chicago-based BYD vice president.
"And you don’t create the zero carbon zero emissions ecosystem by just producing a whole bunch of electric vehicles. If BYD were to sell tens of thousands of electric vehicles in Tianjin and Beijing, it would create a worse environmental condition than China has today. All they have (to produce electricity) are coal-burning plants."
PluginCars reports that instead, BYD wants to couple solar energy generation with massive amounts of stationary storage using its batteries. 
"We want to sell solar panels," Austin said. "We want to sell solar-shaded parking. We want to sell LED lighting. We want to sell energy storage for your home, and charging stations coupled to energy storage. Oh, and you can use solar panels to charge your energy storage that’s now powering your vehicle."
