Battery storage is booming. Just look at Tesla

Tesla Energy, the clean energy division of Elon Musk’s Tesla, is a prime example of the battery storage boom we’re seeing throughout the United States. In 2024, Tesla deployed 31.4 GWh of energy storage products, equivalent to the annual electricity usage of nearly 3,000 typical American homes. This is more than double Tesla’s deployment in 2023, which saw under 15 GWh worth of energy storage products.

Tesla’s Megapack and Powerwall, which provide large-scale and residential battery storage respectively, have benefited from increased consumer demand and larger growth in the market. As a whole, the energy storage market had yet another record year in 2024, with growth expected to continue into 2025. Environment America Research & Policy Center has documented the growth of battery energy storage and other clean energy technologies in the interactive Renewables on the Rise dashboard.

As more renewable energy sources come online, battery storage will play an increasingly important role in building the grid of the future. By capturing renewable energy and dispersing it when needed, battery storage provides the flexibility and resiliency needed to integrate renewables and meet modern energy needs.

“Limitless energy from the sun is shining down on our rooftops everyday, and we have the ability to harness it and reliably store it with battery storage,” said Johanna Neumann, Senior Director of the Campaign for 100% Renewable Energy. “Continued deployment of battery storage, both for homeowners and utilities, is crucial for a modern grid.”
