Here in Australia, the government is providing subsidies to households for buying batteries (backed by solar).
After paying $15k (after subsidies) for a 40kWh battery, our battery is filled by roof solar and grid provided renewable energy, when needed, at very cheap rates (6c/kWh). I pay $1 a day for grid connectivity. Our total annual energy bill will be approximately $500 for the foreseeable future.
