does solar power generation require energy storage
How much "backup power" is needed for solar and wind?
Accessing them in combination is a smart way to ensure that renewable energy doesn''t need "backup generation." Rather than building power plants, utilities need to build better power plans. In those plans, there are four key ways that utilities can include solar and wind power while enhancing reliability.
