World : In California, 100% Solar and Wind in 2045 will need $350 billion in energy storage

In California, both wind and solar generation are about ten times less in the lowest months versus the top three months.

If California reaches the 80% mark for renewables there will be massive amounts of surplus generation during the summer months and would need 9.6 million megawatt-hours of energy storage. Achieving 100% would require 36.3 million.

California should reach on 50% of its electricity from clean sources by 2020 and could pass a bill to legally require 100% by 2045. In January, they voted to close a nuclear plant which is a carbon-free source that provides 24% of the electricity.

The amount and cost of the storage will go over $350+ billion because of the wide variation in solar and wind power generation.
