Nuclear energy ETFs provide investors with broad exposure to nuclear energy stocks such as utilities and uranium producers.
That makes the fund less diversified overall, but it can also be somewhat more stable because it excludes the long tail of smaller exploration and production companies that tend to be more volatile.
The large-cap tilt also contributes to stronger income potential. This energy ETF offered a 30-day SEC yield of about 2.65% in March 2026. It is also slightly cheaper, with a 0.08% expense ratio, and far more widely used by investors, with roughly $39 billion in assets under management.
The fund tracks a benchmark of 28 midstream corporations and master limited partnerships, or MLPs. These companies operate pipelines, storage terminals, and other energy transportation assets. Rather than producing or refining energy, their role is to move oil, natural gas, and other resources from point A to point B.
Because many of these businesses operate under long-term contracts, their revenue streams tend to be steadier than those of exploration and production companies. That stability supports higher payouts, and the ETF offered a 30-day SEC yield of about 4.3% in March 2026.
The fund is also fairly popular with investors, managing roughly $31.2 billion in assets. The trade-off is cost, as it carries a 0.45% expense ratio, which is higher than most traditional energy sector ETFs.
The energy sector is in the middle of a strategic reset. Many oil and gas supermajors have pulled back from aggressive environment, social, and governance (ESG) and low-carbon mandates and are refocusing on the core reality that energy is a depletion business. Capital discipline, reserve replacement, and shareholder returns have moved back to the forefront.
At the same time, global energy demand continues to rise. Utilities powering data centers and artificial intelligence (AI) infrastructure are driving incremental demand for electricity, natural gas, and supporting fuels. Natural gas, in particular, plays a growing role as a bridge fuel due to its reliability and lower emissions relative to coal.
Commodity prices and energy producer equities are likely to remain volatile. Crude oil and natural gas prices will continue to oscillate in response to geopolitical developments, especially conflicts and supply disruptions in sensitive regions such as the Middle East, Eastern Europe, and major shipping corridors.
Energy exchange-traded funds (ETFs) give investors exposure to one of the world's most essential industries. Energy underpins almost everything in the global economy, from manufacturing and food production to shipping, cloud computing, and even charging your phone.
Most people notice its importance only when prices spike or supply gets disrupted. That is why interest in energy ETFs often rises during times of market stress or uncertainty.
Here are some of the best energy ETFs investors can consider in 2026, based on assets under management (AUM) and expense ratio.
If your goal is to invest in the broad U.S. energy sector across large-, mid-, and small-cap stocks, Vanguard Energy ETF (VDE +2.17%) is a straightforward option to consider. The fund tracks a market-cap-weighted index of U.S. energy companies and charges a low 0.09% expense ratio.
The ETF holds 106 companies, though its market-cap weighting means the portfolio tilts heavily toward large caps. The median market capitalization of holdings is about $72.3 billion, reflecting the dominance of major integrated oil and gas companies within the sector.
Vanguard's energy ETF is also well established, with about $8.2 billion in assets under management. In addition to sector exposure, the fund offered a 30-day Securities and Exchange Commission (SEC) yield of around 2.4% in March 2026, providing investors with some income alongside exposure to the energy market.
If your preference is toward the largest companies in the U.S. energy sector, a more focused alternative may be State Street's energy ETF, Energy Select Sector SPDR Fund (XLE +2.36%). State Street's energy ETF holds a much narrower portfolio than Vanguard's, with just 22 large-cap energy companies that are already part of the S&P 500.
If you want exposure beyond the United States, iShares Global Energy ETF (IXC +1.82%) offers a broader geographic approach. While the U.S. is home to many dominant energy companies, it is far from the only major player. Looking internationally reveals a wide range of additional oil and gas producers and integrated energy companies, particularly in the European Union and Canada.
This ETF captures that opportunity by investing globally rather than limiting itself to U.S. companies like the Vanguard and State Street energy ETFs. The portfolio holds 51 companies and includes many international energy majors. Because several of these companies historically pay higher dividends than their U.S. peers, the fund currently offers a higher 30-day SEC yield of about 3.48%.
The main drawback is cost. This ETF charges a much higher 0.40% expense ratio. Even so, it has attracted strong investor interest and currently manages about $2.2 billion in assets.
The Vanguard, iShares, and State Street energy ETFs largely focus on the upstream side of the industry, meaning the companies that explore for and produce oil and gas, along with the large integrated majors. Investors looking for a more infrastructure-style exposure to energy, particularly with an emphasis on income, may find Global X MLP & Energy Infrastructure ETF (MLPX +0.87%) appealing.
