Batteries are scaling up faster than ever in the US, enabling record solar growth to continue and reducing fossil fuel use. - https://ember-energy.org/chapter/the-rise-of-batteries-plus-...

> In 2024, California and Nevada led the nation in solar power, becoming the first states to surpass 30% annual solar share, with California hitting 32% and Nevada 31% – the highest shares of any state. But the transition is uneven – while some states are surging ahead, others are just beginning to see significant growth.

> Batteries are essential for the rise of solar, allowing solar to meet growing demand and displacing gas and coal generation. Across the US, the growth of batteries is accelerating alongside solar, with 1 MW of storage being added for every 3 MW of solar added in 2024.
