Consequence of intermittency on the volume of infrastructure to be installed!
The study of California's energy needs up to 2040 is particularly interesting: the state will need 82.3 GW. This will be broken down into 53 GW of solar energy.
It will need 37 GW of battery storage, 4 GW of long-term storage, more than 2 GW of geothermal energy and 24 GW of wind power reserves, all of which will need to be connected to the grid. The state's transmission system will require an investment of US$30.5 billion and a significant increase in energy storage to accommodate the additional power.

Editor's note: The article is interesting because it states that it is not enough to match production to consumption over the year, but to match it minute by minute. This requires battery storage of 70% of annual needs for four hours. Almost 8% of long-term storage is needed and almost half of the annual consumption in the form of wind energy reserves. To this must be added investments in transmission lines.
We are replacing linear production with intermittent production! The cost of replacement is substantial. Are we aware of this?
