Now the fossil fuel companies – from fuel suppliers such as coal miners to coal-burning electric power utilities – will be on the defensive, fighting the new normal of cheaper renewable supplies and storage.
Instead of asking “can we have our own energy system?” communities will be asking “why can’t we have it?”
The Tesla Energy system launched last week is comprehensive, with global ramifications. The Powerwall system offering 10 kWh is targeted at domestic users. It is complemented by a commercial system termed the Powerpack offering 100 kWh storage, and a stack of 100 such units to form a 10 megawatt hour storage unit that can be used at the scale of small electricity grids.
Whole communities could build micro-grid power supply systems around such a 10 MWh energy storage system, fed by renewable energy generation (wind power or rooftop solar power), at costs that just became super-competitive.
At his launch last week, Musk maintained that the entire electric power grid of the US could be replicated with just 160 million of these utility-scale energy storage units. And two billion of the utility-scale units could provide storage of 20 trillion kWh – electric power for the world.
