Wind Plus Solar Plus Storage = 99.9% of Grid Needs, Affordably

I was greatly encouraged today to read the news of a new study in Delaware that suggests that it would be affordable to combine wind and solar with storage to replace substantially all of the nation’s power grid.

The finding is contained in new  research by the University of Delaware and Delaware Technical Community College and reported in Science Daily.

According to the report, “Unlike other studies, the model focused on minimizing costs instead of the traditional approach of matching generation to electricity use. The researchers found that generating more electricity than needed during average hours — in order to meet needs on high-demand but low-wind power hours — would be cheaper than storing excess power for later high demand.”
