Why battery costs have plunged since 2010
Methinks we are moving to wrong direction. Instead of massive battery farms, we should focus on intelligent metering. Every consumer should have wireless metering unit, which shows the price of electricity at every moment with big red numbers. Then it is your choice, you can waste your monies or invest on 100 kwh battery, which can also can optimize the charging-recharging cycle. In Europe the price of electricity is often momentarily negative, when there is good wind blowing. That would the time to bake the pie and clean youres freezer.
