Large Scale Battery Storage of Electricity

This is a highly desirable approach to making solar and wind power generation key players in low carbon emissions power generation. When the sun sets, or when the wind does not blow, these two forms of power generation are of little or no value. But if the electricity generated when the sun shines, or the wind blows, could be stored and used later, then we have a means of consistent wind and solar power supply.

Large efficient batteries can achieve this, and some are being built for just such a purpose...... And still more efficient batteries are being developed. For details on what is in the works, read Gates, Pritzkers Take on Musk in $5 Billion Race for Battery Storage
