Long-winded benefits - electrical energy storage systems

The best wind-
Energy facilities can generate electricity at the same cost as large coaland nuclear-powered plants.
However, compared with these old factories, the wind
Power generators are less reliable because they depend on the wind.
According to the team of energy analysts led by Paul Denholm of the golden National Renewable Energy Laboratory in Colorado.
If excess energy is saved in strong winds, the reliability of the wind system can be improved. Such energy-
The researchers said the storage system can provide full power in about 80% of the time, which is comparable to the performance of traditional power plants.
How to save energy is our challenge.
There is a very good solution: save the remaining wind energy in the underground cave as compressed air, and then use it later to run the generator.
This system occasionally requires an increase in fossil fuel, but it is not enough to seriously damage wind power.
