In our latest Short-Term Energy Outlook, we forecast U.S. working natural gas inventories will reach 3,872 billion cubic feet (Bcf) by the end of October, or 2% more than the previous five-year average for that time of year. Natural gas inventories grew quickly in late April through early June, with seven consecutive weeks of net injections to inventories exceeding 100 Bcf each for the first time since 2014.

U.S. natural gas production outpaced natural gas consumption during the start of the 2025 injection season. The injection season generally runs from April through October, when injections into storage are typically greater than withdrawals. The latest data from our Weekly Natural Gas Storage Report show total natural gas inventory was 7% above the five-year (2020–24) average as of August 8, compared with the start

Even without accounting for electricity interruptions resulting from major events such as hurricanes, customers in Puerto Rico experienced on average 27 hours of power grid interruptions per year between 2021 and 2024. By comparison, electricity customers in the mainland United States generally experience about two hours of electricity interruptions per year without major events.

Hurricanes and other major events add to the outage time customers experience. In August 2024, Hurricane Ernesto affected at least 1 million customers in Puerto Rico. On average in 2024, customers in Puerto Rico went without electricity for more than 73 hours, of which 43 hours were attributed to major events such as hurricanes. In September 2022, Hurricane Fiona left all 1.5 million electricity customers in Puerto Rico without power. The average customer in Puerto Rico experienced almost

In 2024, the United States exported about 30% of its domestic primary energy production. This percentage has grown considerably in recent decades, according to data in our Monthly Energy Review. Nearly all of the exports were fossil fuels destined for other countries in North America, Europe, or Asia.

The United States set multiple records for energy production and exports in 2024. Of the record 103 quadrillion British thermal units (quads) of total primary energy production in the United States, a record 31 quads went to other countries. The energy production that is not exported is not necessarily equivalent to domestic consumption because domestic consumption also includes energy imports and withdrawals from storage.

In our Monthly Energy Review, we convert different measurements for different sources of energy to one common unit of

Five countries account for more than two-thirds of the world’s total nuclear electricity generation capacity. The United States has the most capacity, followed by France, China, Russia, and South Korea, based on International Atomic Energy Agency (IAEA) data as of June 2025. Globally, 416 nuclear power reactors are operating in 31 countries, with a total installed net generating capacity of 376 gigawatts (GW).

The development of nuclear power plants for commercial electricity generation began in the United States in the late 1950s with the commissioning of the Shippingport Atomic Power Station in Pennsylvania. Most of the operating U.S. nuclear generating capacity was constructed between 1967 and 1990.

Electric utilities in the United States currently operate 94 nuclear reactors, and the country is the world’s largest producer of nuclear electricity. Domestically, nuclear
