Just been looking into energy sector plays, and there's something worth paying attention to here. With all the AI infrastructure buildout happening, data center power demands are absolutely exploding. Bloomberg's latest forecast has data-center power demand hitting 106 gigawatts by 2035 — that's a 36% jump from just seven months ago. Pretty wild acceleration.

One fund that's positioned to ride this wave is the Vanguard Energy ETF (VDE). It's honestly one of the best ETF options to buy today if you're thinking long-term energy exposure. Why? A few solid reasons.

First, it's a Vanguard product, so you know the fee structure is clean. The expense ratio sits at just 0.09% annually — meaning you're only paying $9 per year on a $10,000 investment. That's the kind of low-cost structure that actually matters when you're holding something for years.

Second, the timing feels right. Data centers are transitioning fast. Right now only 10% of facilities pull more than 50 megawatts, but over the next decade, new builds will average over 100 megawatts each. Some will hit 500 megawatts or more. That's a structural shift in energy demand that's just getting started.

Third angle — and this matters if you like passive income — the fund throws off a solid 3% dividend yield. So you're getting both potential upside from the energy sector tailwinds plus regular distributions.

Now, nothing's guaranteed. Energy markets have their own volatility. But if you're looking for one of the best ETFs to buy today with a real growth narrative behind it, this one checks boxes. The AI energy story is just getting going, and the energy sector looks positioned to benefit for years to come.
