Energy Storage: Balancing the 21st Century Power Grid

While many people think of natural gas as the "go-to" fuel of the decade and near future, it is remarkable how much renewable energy is being installed. In 2013, approximately 44% of all new electric generation capacity (on a nameplate megawatt basis) installed in the United States came from solar and wind. In 2014, that amount increased to 53% [1] (see Figure 1).
