For the wind industry, the findings were very favorable. "Wind technologies generate far more energy than they consume," Dale said.
Why are wind energy storage units so difficult to build?
Until July 2020, the government made storage units incredibly difficult to build, which in turn dampened the potential of wind energy. To put it another way, why would operators care about all those gigawatts if they can’t monetise them, buying and selling excess energy as the nation demands?
Is wind energy storage a problem in the UK?
Wind energy storage in the UK has also posed a problem as the number of turbines increase, but new technology and battery methods are coming.
Are high wind energy resources suitable for compressed air energy storage (CAES)?

What happens if there is no wind?
When there is no wind or the wind is not enough to satisfy the demand, the energy is released from the storage system (green colored area). As a result, the generator power could shift from the blue line to the green line with such storage to allow wind energy to be converted into a desirable on-demand power supply.
