What is the cost to 'upgrade' to pure electric supply / generation household? Say per SF? And why would you remove gas connections when they could be used as backup? Plus why is this what future holds should look like?
The batteries are the backup. Keeping gas service "just in case" comes with it's own risks in terms of leaks, and where I live, with major earthquakes. Disconnecting it means I don't have to worry about that, or pay the $4/mo minimum to keep it active.
I believe this is the future we need if we're serious about eliminating CO2 emissions. It's not just power plants and cars - my house put out just as many emissions in the winter as my car did. Probably more. In a world where we're getting CO2 to zero there's no place for gas appliances. We need everyone to accept that, and it's going to take a while.
