As of 2024, the U.S. boasts an electric generating capacity of approximately 1,250 GWs, with natural gas, renewables (especially solar and wind), coal, nuclear, and hydroelectric power comprising the majority. While natural gas currently holds the largest share at 40-45%, renewables have been on the rise, collectively accounting for over 25% of the capacity. The country aims to significantly increase its generating capacity by 2040 by transitioning to cleaner, renewable energy sources and energy storage technologies, aligning with decarbonization goals and energy demand in sectors like transportation and industry. Projections suggest the addition of 400 to 600 GWs of new capacity, mainly from solar, wind, and battery storage, supported by favorable policies and incentives. Solar power is expected to lead the expansion, potentially adding over 300 GWs, with wind power and energy storage also playing crucial roles in the new capacity. The gradual decline of natural gas is foreseen as renewables expand, while nuclear power, including Small Modular Reactors (SMRs), could contribute zero-carbon baseload power if successfully developed. The transition to a cleaner energy system will necessitate substantial investments in infrastructure, policy backing, and technological advancements.
