Summary:
Researchers have found that the wind industry can easily afford the energetic cost of building batteries and other grid-scale storage technologies due to Wind Power Surplus.
However, for the solar industry, scientists found that more work is needed to make grid-scale storage energetically sustainable

Wind Power Surplus

A big challenge for utilities is finding new ways to store surplus wind energy and deliver it on demand. It takes lots of energy to build wind turbines and batteries for the electric grid. But Stanford scientists have found that the global wind industry produces enough electricity to easily afford the energetic cost of building grid-scale storage.

The dramatic growth of the wind and solar industries has led utilities to begin testing large-scale technologies capable of storing surplus clean electricity and delivering it on demand when sunlight and wind are in short supply.

Now a team of Stanford researchers has looked at the “energetic cost” of manufacturing batteries and other storage technologies for the electrical grid. At issue is whether renewable energy supplies, such as wind power and solar photovoltaics, produce enough energy to fuel both their own growth and the growth of the necessary energy storage industry.
