Really? Try and tell that to the 1000s of people who are using Elon Musk's Power Wall for load shifting, backup power, and off-the-grid use. 
Elon Musk has proven that power storage can be profitable and he invested millions to do just that. Go read more about this project here, https://www.tesla.com/powerwall
We need to start thinking out of the box, like Elon Musk and his team of engineers, to reduce Bitcoin's electricity footprint.

you do realise that getting 1KW from the grid and putting it into a battery as potential energy. does not mean you will get out 1kw when you later use the potential energy
its why when you charge a battery for 6 hours you only get 2 hours USE out of the battery(dont pretend standby time is real use)
EG solar power to lightbulb direct=7 hours of light
EG solar power to battery to lightbulb =less than 7 hours of light
